Analyzing the Convexity of Current US Mortgage Backed Securities Portfolios

Retirement planning operates as a strict mathematical exercise in capital preservation and income generation. The fixed income portion of a portfolio bears the heavy responsibility of funding your daily life when the equity markets turn hostile. Many investors reflexively allocate a massive portion of their wealth into generic bond funds without examining the underlying mechanics of what they actually own. A heavy allocation to United States Mortgage-Backed Securities sits inside almost every broad bond index fund on the market. These securities offer an attractive yield premium over standard government debt. They pay you more money. They do not pay you more money out of corporate generosity. They pay you a premium because you are assuming a highly specific, mathematically complex risk. This risk is called negative convexity.

Understanding convexity separates the amateur yield chaser from the professional capital allocator. You cannot simply look at the headline yield of an MBS fund and assume it behaves like a standard Treasury bond. It does not. The underlying asset is a pool of residential mortgages. Every single homeowner in that pool holds a legal right to break their contract and hand your money back to you exactly when you do not want it. Analyzing the convexity of current US Mortgage-Backed Securities portfolios requires a cold look at the 2026 interest rate environment, the behavior of the American homeowner, and the pricing of options-adjusted spreads. If you rely on fixed income to pay your property taxes, you need to know exactly how these assets react when the Federal Reserve moves the cost of capital.

The Role of MBS in Retirement Income Strategies

Mortgage-backed securities represent a massive slice of the global fixed income market. When you buy a share of an ETF tracking the Bloomberg US Aggregate Bond Index, nearly thirty percent of your money flows directly into agency MBS. These are pools of thousands of individual home loans bundled together by government-sponsored enterprises like Fannie Mae and Freddie Mac. As the homeowners pay their monthly mortgage bills, the servicer collects the cash, subtracts a small administrative fee, and passes the principal and interest through to you, the investor. This pass-through structure provides a monthly stream of cash flow that perfectly matches the consumption needs of a retiree.

The primary function of these assets in a retirement portfolio is to boost the overall yield without introducing massive default risk. A retiree cannot put all their money into high-yield junk bonds. The default risk during an economic contraction would destroy their capital base. They also cannot put all their money into short-term Treasury bills if those bills yield less than the rate of inflation over a ten-year horizon. MBS sits precisely in the middle. It offers a spread above the risk-free rate, providing the extra income required to maintain purchasing power throughout a thirty-year retirement timeline.

Yield Generation Versus Corporate Bonds

Corporate bonds offer another avenue for yield. A solid investment-grade bond from a company like Johnson & Johnson or Microsoft will pay a steady coupon. However, corporate bonds carry credit risk. If the company mismanages its balance sheet or faces a catastrophic lawsuit, the bond value plummets. Furthermore, corporate bonds usually pay interest semi-annually. A retiree managing cash flow often prefers the monthly distribution schedule inherent to mortgage-backed securities. The yields on agency MBS frequently rival the yields on high-quality corporate bonds, making them a highly competitive alternative for the income sleeve of an investment portfolio.

The structural difference lies in the maturity. A corporate bond has a bullet maturity. The company borrows ten million dollars for ten years, pays interest along the way, and hands back exactly ten million dollars on the final day. The cash flows are predictable. Mortgage-backed securities pay down principal every single month. A portion of the monthly check you receive is interest, and a portion is your own money being returned to you. You have to reinvest that returned principal constantly. This reinvestment requirement forces the investor to continually interact with current market rates, altering the yield profile of the asset class compared to corporate debt.

The Implicit Government Guarantee and Risk Mitigation

Credit risk in agency MBS is functionally nonexistent. Fannie Mae, Freddie Mac, and Ginnie Mae guarantee the timely payment of principal and interest. If a homeowner in Sacramento loses their job and defaults on their mortgage, the GSE steps in and makes the investor whole. Ginnie Mae holds an explicit guarantee from the full faith and credit of the United States government. Fannie Mae and Freddie Mac hold an implicit guarantee, which the market treats as ironclad. You are not taking credit risk when you buy an agency MBS. You will get your money back.

Because credit risk is removed from the equation, the yield premium you receive over a Treasury bond compensates you for something else entirely. It compensates you for timing risk. The government guarantees that you will receive your principal. They do not guarantee exactly when you will receive it. A homeowner might pay the loan off in thirty years, or they might pay it off in three months. This timing uncertainty defines the entire asset class and introduces the concept of convexity to the retirement portfolio.

Defining Convexity in Fixed Income Markets

Duration measures how much a bond's price will change for a one percent shift in interest rates. It acts as a linear approximation. If a bond has a duration of five years, and interest rates drop by one percent, the bond price should rise by roughly five percent. This linear math works well for very tiny movements in yield. The real world does not operate in straight lines. The price-yield relationship of a bond is actually curved. Convexity measures the exact curvature of that line. It tells you how much the duration itself changes as interest rates move.

Think of duration as the speed of a car. Convexity is the acceleration. If you only look at speed, you fail to predict where the car will be if the driver stomps on the gas pedal. In bond math, high positive convexity is a highly desirable trait. It means the bond's price will accelerate upward faster than duration alone suggests when rates fall. It also means the bond's price will decelerate its decline when rates rise. Investors pay a premium to own assets with positive convexity because it protects their capital in volatile markets.

Positive Convexity in Traditional Treasury Bonds

A standard United States Treasury bond exhibits positive convexity. If you buy a ten-year Treasury note yielding four percent, you hold a static contract. The US Treasury cannot call the bond early just because interest rates drop to two percent. They are locked into paying you four percent for the entire decade. Therefore, if market rates collapse, the value of your four percent bond skyrockets. The upside is mathematically uncapped by any early redemption feature. The price-yield curve bows outward.

When interest rates rise from four percent to six percent, the Treasury bond loses value. However, the rate of that loss slows down as the price falls lower. The positive convexity acts as a cushion. The bond becomes less sensitive to further rate hikes the more its price drops. For a retiree relying on capital preservation, positive convexity is a defensive wall. It maximizes capital gains during rate cuts and minimizes capital destruction during rate hikes.

The Mathematical Reality of Negative Convexity

Negative convexity reverses the math. A bond with negative convexity will see its duration shorten when interest rates fall. The price appreciation hits a mathematical ceiling. The curve bows inward. When interest rates rise, the duration lengthens, causing the price to drop faster and harder than a linear duration model would predict. You get the worst of both worlds. Your upside is strictly limited, and your downside is actively accelerating.

Why would any rational investor buy an asset with negative convexity? They buy it because the market prices this flaw into the asset. To convince you to accept the risk of capped upside and accelerating downside, the issuer must pay you a higher baseline yield. This is the exact tradeoff occurring inside a mortgage-backed security. You are trading price appreciation potential for a higher monthly income stream. You accept negative convexity to increase your immediate cash flow.

The Embedded Call Option of the American Homeowner

The root cause of this negative convexity is the American mortgage contract. When a borrower takes out a thirty-year fixed-rate mortgage, they sign a document that gives them an incredible amount of power over the lender. The borrower has the right to prepay the loan at any time, for any reason, without a financial penalty. They can pay an extra hundred dollars a month, they can sell the house and pay off the entire balance, or they can refinance the debt with a new bank. They hold an embedded call option on the loan.

Every time you buy a mortgage-backed security, you are simultaneously buying a bond and selling a call option to thousands of anonymous homeowners. Because you sold the option, you collect an option premium. That premium takes the form of the higher yield on the MBS. The homeowner will only exercise that option when it benefits them, which mathematically guarantees it will harm you. You are on the opposite side of the trade against millions of self-interested consumers.

Refinancing Waves and Prepayment Speeds

Homeowners act rationally. They watch mortgage rates. The industry measures their behavior using metrics like the Conditional Prepayment Rate. If you hold a pool of mortgages yielding seven percent, and current market rates drop to five and a half percent, the prepayments will spike. Mortgage brokers will aggressively call every homeowner in your pool, offering to lower their monthly payment. A massive refinancing wave begins. The homeowners exercise their embedded call option. They take out a new loan at five and a half percent and use that cash to pay off the seven percent loan you hold.

Your pass-through check next month will be massive. The servicer will hand you back thousands of dollars in principal. This sounds good until you realize you now have a pile of cash sitting in a brokerage account earning zero. You have to take that cash and reinvest it in the current market. The current market only offers five and a half percent. Your high-yielding asset vanished exactly when it became most valuable.

Contraction Risk When Interest Rates Fall

This phenomenon is known as contraction risk. The duration of your MBS portfolio shrinks violently during a rate rally. You bought an asset you thought had a duration of five years. Suddenly, due to mass refinancing, the cash is returned to you in two years. The asset contracted. In a normal bond market, falling rates create massive capital gains. In the MBS market, falling rates trigger mass executions of the call option, destroying your asset and forcing you to reinvest at lower yields.

This risk devastates the income projections of a retirement plan. If you built a spreadsheet assuming a six percent yield for the next ten years, and a rate cut forces you to reinvest half your portfolio at four percent, your monthly income drops significantly. You cannot force the homeowners to keep the expensive debt. Contraction risk ensures that your portfolio yield will always trend downward during aggressive Federal Reserve easing cycles.

The Cap on Portfolio Capital Appreciation

Contraction risk creates the physical price ceiling of negative convexity. A generic corporate bond might trade at 115 cents on the dollar if rates plummet. An MBS will rarely trade far above 102 or 103 cents on the dollar. Why would an institutional trader pay 105 for a bond that a homeowner can legally pay off at 100 tomorrow morning? They will not. The mere threat of prepayment caps the price of the security. You lose the capital appreciation that usually buffers a fixed income portfolio during economic downturns.

Extension Risk When Interest Rates Rise

The dark mirror of contraction risk is extension risk. Imagine you buy an MBS yielding three percent. The Federal Reserve initiates an aggressive hiking cycle to fight inflation. Current mortgage rates shoot up to seven percent. The homeowners in your pool holding three percent mortgages will never refinance. They will cling to that cheap debt with absolute desperation. They will not move to a new city. They will not upgrade to a larger house. They will stay put to avoid taking on a seven percent loan.

Prepayment speeds grind to an absolute halt. The principal you expected to receive back in five years will now take twelve years to arrive. The duration of your asset extends rapidly. This happens precisely when interest rates are rising. As the duration lengthens, the mathematical sensitivity of the bond to those rising rates increases. The price of your MBS falls faster than a comparable Treasury bond. The negative convexity punishes you severely on the downside.

Being Locked into Subpar Yields for Decades

Extension risk traps your capital. You are forced to hold a three percent yielding asset in a seven percent world. Because the homeowners refuse to prepay, you receive very little principal back each month. You have no cash to reinvest at the new, higher rates. Your portfolio is effectively frozen in the past. If you need to sell the MBS to fund a medical expense, you will have to sell it at a massive discount to par value. The market will demand a heavy price concession to take that low-yielding paper off your hands.

The Current 2026 Interest Rate Environment

Evaluating convexity requires locating yourself on the macroeconomic timeline. In 2022 and 2023, the fixed income market suffered historical destruction as the Federal Reserve raised the federal funds rate rapidly. MBS portfolios experienced maximum extension risk. Prepayment speeds hit multi-decade lows. The year 2025 provided significant relief, generating some of the strongest returns for the asset class in twenty years. Now, operating in 2026, the landscape looks entirely different. We are in an environment defined by easing inflation, moderating employment data, and shifting central bank priorities.

The current macroeconomic setup dictates how the prepayment models function. We are no longer dealing with extreme shocks. The market expects a normalized path of monetary policy. This normalization directly impacts the severity of the negative convexity embedded in these mortgage pools. You cannot analyze a bond portfolio using the fears of 2022 when you are investing in the reality of 2026.

The Federal Reserve and Slow Drip Rate Cuts

The Federal Reserve began cutting rates in late 2025. By early 2026, they established a pattern of slow, methodical reductions. This is not a panic-driven zero-interest-rate policy environment. They are cutting rates by twenty-five basis points at a time to maintain a neutral policy stance as inflation approaches the two percent target. For MBS investors, this slow drip is the absolute ideal scenario. It provides a tailwind for bond prices without triggering a catastrophic wave of refinancing.

If the Fed slashed rates by two hundred basis points overnight, mortgage rates would plummet, and contraction risk would wipe out high-coupon MBS pools instantly. A slow reduction allows investors to capture the yield premium while the underlying bonds appreciate gently toward par value. The homeowners look at a drop from 6.8 percent to 6.2 percent and decide it is not quite enough to justify the closing costs of a refinance. The investor keeps the high yield. The negative convexity remains dormant.

A Steeper Yield Curve and MBS Performance

The shape of the yield curve dictates the profitability of banking institutions and the relative attractiveness of mortgage bonds. During the inflation fight, the yield curve was deeply inverted. Short-term rates yielded more than long-term rates. In 2026, the curve steepened significantly. The spread between the two-year Treasury and the ten-year Treasury normalized into a positive slope. This steepening improves the carry profile of the asset class.

A steeper curve helps mitigate the sting of negative convexity. When the curve is steep, the forward path of interest rates is priced more rationally. Homeowners base their refinancing decisions on the ten-year sector of the curve, where standard thirty-year mortgage rates derive their pricing. The steepening curve provides a stable baseline for pricing the embedded option. The fixed income market rewards this stability by tightening the spreads on agency paper, driving up the capital value of the bonds held in your retirement account.

Falling Rate Volatility as a Major Tailwind

Convexity is fundamentally an options pricing problem. The value of any option derives heavily from implied volatility. If you own a stock and sell a call option on it, you demand a massive premium if the stock swings wildly by ten percent a day. If the stock barely moves, the option premium drops. The exact same math applies to the embedded call option in a mortgage. Interest rate volatility is the primary enemy of the MBS investor. When volatility is high, the value of the homeowner's option increases, which directly decreases the value of your bond.

The ICE BofA MOVE Index tracks the implied volatility of US Treasury options. During 2022 and 2023, the MOVE index sat at incredibly elevated levels. Nobody knew where rates would peak. By 2026, the MOVE index collapsed back to historical norms. The market largely agrees on the trajectory of central bank policy. This collapse in volatility is the single greatest tailwind for MBS performance in the current market.

The Relationship Between Volatility and Refinancing Models

Low volatility makes forecasting easier. When rate volatility drops, the massive institutional computer models that predict prepayment speeds generate tighter confidence intervals. If a model knows that rates will likely stay within a narrow fifty-basis-point band for the next twelve months, it can accurately price the exact probability of a homeowner in Ohio refinancing their loan. The uncertainty premium vanishes from the market.

When the uncertainty premium vanishes, institutional buyers bid up the price of the bonds. You benefit directly. The negative convexity of the portfolio matters far less when the underlying variable—interest rates—refuses to move aggressively. The bonds behave more like traditional positive convexity assets because the boundaries of the embedded option are rarely tested. You collect the high yield without suffering the severe price whiplash.

Options-Adjusted Spread Dynamics in 2026

You cannot measure the value of an MBS by simply looking at its nominal spread over a Treasury bond. You must use the Options-Adjusted Spread. The OAS strips out the cost of the embedded call option using complex Monte Carlo simulations across thousands of potential interest rate paths. It gives you the true, pure yield premium you are receiving for taking on the asset. If the OAS is wide, the bond is cheap. If the OAS is tight, the bond is expensive.

Entering 2026, the OAS on agency MBS remains historically attractive compared to investment-grade corporate credit. Corporate spreads compressed to incredibly tight levels as investors desperately bought debt to lock in yields before the Fed cut rates further. The corporate bond market priced in absolute economic perfection. The MBS market, still bearing the psychological scars of the 2022 extension risk event, offered a wider OAS. A savvy retirement planner recognizes this discrepancy. You are currently getting paid more per unit of risk in the mortgage market than in the corporate bond market, even after adjusting for the negative convexity.

Evaluating Institutional Demand for MBS Assets

Retail investors do not move the mortgage market. A guy buying a thousand shares of a bond ETF in his IRA is a rounding error. The market moves based on the behavior of massive institutional players: commercial banks, foreign central banks, and government-sponsored enterprises. You have to analyze the purchasing intentions of these heavyweights to understand the technical setup for the asset class in 2026. If the big buyers disappear, spreads will widen, and your portfolio will lose value regardless of the macroeconomic fundamentals.

Supply and demand mechanics override theoretical bond math in the short term. The supply of new mortgage bonds depends on the housing market. In 2026, housing turnover remains relatively constrained. People are not selling their homes at the rapid pace seen in 2021. Therefore, the net new supply of agency MBS hitting the market is highly manageable. The equation then rests entirely on the demand side of the ledger.

Commercial Bank Purchasing Trends and Basel III

Commercial banks traditionally serve as the primary buyers of mortgage-backed securities. They take in short-term deposits from checking accounts and buy long-term, high-quality liquid assets like MBS to earn the spread. This mechanism broke down recently. Deposit growth was sluggish, and banks faced heavy regulatory scrutiny regarding unrealized losses on their bond portfolios. They stepped away from the MBS market, allowing spreads to widen.

In 2026, the regulatory environment shifted. Federal regulators indicated a softer approach to the Basel III endgame capital requirements. This relief on securitization capital frees up bank balance sheets. As short-term rates drop, deposits become cheaper for banks to acquire. They take those cheap deposits and immediately deploy them into the MBS market to capture the attractive Options-Adjusted Spread. This resurgence of bank demand puts a solid floor under the price of mortgage bonds, offsetting the natural drag of negative convexity.

Government Sponsored Enterprise Intervention

The true wildcard in the mortgage market is direct government intervention. The Federal Reserve spent years running off its massive MBS portfolio through quantitative tightening. They were the dominant buyer for a decade, and their exit caused massive indigestion. The market eventually absorbed the supply. Now, a new buyer has emerged to fill the void. The political pressure to lower mortgage rates and stimulate housing affordability forced action at the federal level.

The GSEs themselves—Fannie Mae and Freddie Mac—retained the authority to purchase specific tranches of their own paper. When housing policy dictates a need for lower consumer borrowing costs, these entities use their massive balance sheets to buy MBS directly from the open market. This artificial demand artificially suppresses yields and drives up bond prices. You are investing alongside a buyer who possesses infinite capital and a political mandate rather than a profit motive.

Trillions in Securitization and Policy Impacts

The scale of this market defies basic comprehension. We are talking about an asset class measured in the trillions of dollars. A policy announcement regarding two hundred billion dollars in targeted MBS purchases creates immediate, violent price action. Institutional traders front-run the government buying. If you hold a broad MBS index fund, your portfolio captures this policy-driven capital appreciation. The negative convexity limits the upside, but the sheer volume of government buying forces the price against that mathematical ceiling, ensuring you extract the maximum possible total return from the security.

Portfolio Rebalancing for the Aging Investor

You do not build a retirement portfolio by hoarding a single asset class. You build it by combining assets with contrasting behaviors. Mortgage-backed securities serve a highly specific function: they generate superior cash flow with zero credit risk. They fail entirely at providing explosive capital appreciation during a severe economic crash. If the stock market drops thirty percent and the Federal Reserve takes interest rates back to zero, your MBS portfolio will suffer severe contraction risk. You will get your cash back, but you will not get the massive price spike you need to rebalance into cheap equities.

Therefore, you must pair your MBS holdings with assets that exhibit strong positive convexity. You construct a barbell strategy. You use the mortgage bonds for their high carry and steady income. You use other fixed income instruments for their defensive geometry. This combination ensures your portfolio bends without breaking during extreme macroeconomic events.

Pairing MBS with Long Duration Treasuries

The perfect hedge for a heavy MBS allocation is a position in long-duration US Treasury bonds, such as the twenty-year or thirty-year Treasury bond. These assets possess massive positive convexity. If a recession hits and rates collapse, the price of a thirty-year Treasury bond will explode upward by twenty or thirty percent. This capital gain provides the exact defense you need when your equity portfolio is bleeding.

While the long Treasury protects the downside of the macro environment, the MBS provides the yield during normal times. The thirty-year Treasury pays a relatively low yield compared to a mortgage bond. Holding too much long Treasury paper acts as a severe drag on your monthly cash flow. By holding both, you blend the characteristics. The MBS pays your grocery bills in 2026. The long Treasury acts as an insurance policy against a deflationary crash in 2028. You manage the negative convexity of the mortgages by diluting it with the positive convexity of the sovereign debt.

Managing Convexity Risk Through Active Management

Retail investors usually buy massive, passive ETFs like the iShares MBS ETF. These funds blindly track an index. If the index is heavily weighted toward generic, low-coupon mortgages issued in 2021, the passive ETF buys them. These specific bonds carry massive extension risk. They are dead money. Passive funds offer cheap expense ratios, but they force you to own the ugliest, most inefficient parts of the mortgage market.

Active management thrives in the MBS space. A professional portfolio manager can selectively buy highly specific mortgage pools. They can buy pools composed entirely of loans from states with high moving costs, where refinancing is less common. They can buy specified pools with lower loan balances, where the homeowner is less likely to bother going through the paperwork of a refinance to save fifty dollars a month. By actively selecting the underlying loans, the manager physically alters the convexity profile of the fund. Paying a slightly higher management fee for an active fixed income fund frequently pays off by avoiding the worst traps of contraction and extension risk.

Personal Reflections on Fixed Income Investing

I spent years treating the bond market as an afterthought. Like most people heavily focused on building a retirement portfolio, I obsessed over equity valuations, dividend growth rates, and emerging market technicals. I viewed fixed income simply as cash waiting to be deployed. I bought a generic total bond market index fund and completely ignored what was happening under the hood. That ignorance cost me a significant amount of money when the interest rate environment fractured in 2022. I watched the value of my bond holdings drop by fifteen percent in a matter of months. I learned a brutal lesson about duration and extension risk the hard way.

The failure forced me to actually read the prospectuses. I tore apart the components of the aggregate bond index. I realized that a third of my safe money was tied up in the psychological behavior of millions of random people deciding whether or not to refinance their split-level ranchers. The realization that I was functionally short a call option to the entire American middle class completely changed my view on fixed income. You are never just collecting a yield. You are always taking a specific risk. In the MBS market, you are betting that homeowners will act lazily. You are betting they will not refinance when they should, and they will not move when they could.

I eventually restructured my retirement accounts to handle this reality. I stopped using passive funds for my mortgage exposure. I moved the capital into actively managed mutual funds where the managers specialize in specified pools. I also barbells the exposure heavily with long-dated Treasuries. If you are fifty-five years old and staring down the barrel of a thirty-year retirement, you cannot afford to misunderstand the math of your income generation. Negative convexity sounds like an academic term until it destroys your monthly cash flow. Understand the mechanism, respect the math, and build a portfolio that actually survives the inevitable shifts in monetary policy.

Frequently Asked Questions

What exactly does negative convexity mean for my bond portfolio?
Negative convexity means the price of your bond will not rise as much as expected when interest rates fall, but it will drop faster than expected when interest rates rise. Your upside is capped by the borrower's right to pay off the loan early, while your downside accelerates because the borrower will refuse to pay off a low-rate loan in a high-rate environment.

Why do mortgage-backed securities have negative convexity?
They have negative convexity because the underlying asset is a residential mortgage. American mortgages allow the homeowner to prepay the loan at any time without penalty. When rates drop, homeowners refinance, forcing the investor to take their cash back and reinvest it at lower market yields.

Is it safer to buy corporate bonds instead of MBS for retirement income?
It depends on the type of risk you want to take. Corporate bonds have positive convexity but carry credit risk; the company could default. MBS carries zero credit risk due to government guarantees, but it carries timing risk and negative convexity. A balanced retirement portfolio usually holds both to diversify the risk types.

How does a steeper yield curve benefit MBS investments?
A steeper yield curve generally improves the income profile of the asset class and stabilizes prepayment speeds. Because mortgage rates are tied to the ten-year Treasury, a normal, steep curve provides a more predictable environment for forecasting homeowner refinancing behavior, which tightens spreads and increases bond values.

What is extension risk and why is it dangerous?
Extension risk occurs when interest rates rise rapidly. Homeowners hold onto their low-rate mortgages, causing the expected lifespan of the MBS to extend drastically. The investor is trapped holding a low-yielding asset for much longer than anticipated, and the market value of the bond plummets.

Should I use an active or passive fund for mortgage-backed securities?
Active management is generally preferred in the MBS space. The mortgage market is highly complex, and an active manager can select specific loan pools that exhibit better convexity profiles, avoiding the worst effects of mass refinancing. Passive index funds are forced to buy the entire market, including the highly inefficient, poorly structured bonds.

How do commercial banks affect the price of MBS?
Commercial banks are massive buyers of mortgage-backed securities. When banks have excess deposits and favorable regulatory capital rules, they buy billions of dollars of MBS, driving up the price and lowering the yield. If banks step away from the market, prices drop. Monitoring bank demand is critical for forecasting MBS performance.

Does holding MBS protect me against a stock market crash?
Only partially. Because of negative convexity, MBS prices will not skyrocket during a severe recession when the Federal Reserve slashes rates. You will get your principal back safely, but you will not experience the massive capital appreciation that standard long-duration Treasury bonds provide during an equity panic.
