In the summer of 1981, Paul Volcker's Federal Reserve pushed the federal funds rate above 19 percent, and long-term bondholders watched decades of capital evaporate. In the summer of 2020, the same central bank held rates near zero, and bondholders complained of the opposite problem: coupons so thin they barely covered inflation. Two eras, two opposite complaints, one shared lesson. The bond that looks safe in one rate regime can become the portfolio's biggest problem in the next, and the exit playbook has to change with the regime.
Most investors learn duration as a textbook definition. It is better learned as a clock. A bond with a duration of eight years will lose roughly 8 percent of its value if yields rise by one percentage point, and gain roughly the same if yields fall. That single number explains why the supposedly conservative part of a portfolio produced double-digit losses in 2022, and why it produced double-digit gains in other years. Duration is not a footnote. It is the dominant risk in high-quality bonds, and managing it means managing exits — shortening duration before rates rise, lengthening it before they fall, or holding steady and accepting the ride.
Reading the regime before choosing the exit
A useful playbook starts with three questions. First, what is the central bank actually doing? Between March 2022 and July 2023, the Fed delivered 11 rate increases, then held rates at 5.25 to 5.50 percent for more than a year before a first cut in September 2024. A manager exiting long bonds in early 2022 faced a different market from one exiting in late 2024: the first was escaping tightening, the second potentially surrendering gains as cuts arrived.
What is the yield curve paying for? When the curve inverts — short rates above long rates, as happened through much of 2022 and 2023 — the market is signalling that today's tight policy may give way to slower growth. In that environment, exiting long bonds to sit in Treasury bills can look rational on income alone: in mid-2023, three-month bills yielded above 5 percent, more than the 10-year Treasury. But an inverted curve also warns that the bill yield may not last. The investor who exits duration entirely may lock in today's income and miss tomorrow's price gain when the Fed eases. The playbook answer is rarely all-or-nothing. It is usually a partial exit, a barbell of short and long maturities, or a ladder that matures steadily and can be reinvested at new rates.
What is credit compensating? Spreads — the extra yield corporate bonds pay over Treasuries — compress when confidence is high and explode when it is not. The ICE BofA U.S. High Yield Index option-adjusted spread, a standard gauge, has swung from below 300 basis points in calm years to above 1,000 basis points in crises such as 2008 and the spring of 2020. Investment-grade spreads move less dramatically but follow the same logic. A manager deciding whether to exit a corporate bond should ask whether the spread still pays for the risk of downgrade or default. In 2021, when high-yield spreads fell below 300 basis points, many managers concluded that the answer was no, and trimmed credit before the 2022 selloff widened spreads again. Those who waited for a headline to justify selling paid a wider spread to get out.
Three exits, three different logics
Consider three positions a manager might hold today, and how the exit logic differs for each.
A long Treasury bond is an interest-rate bet, pure and simple. Its exit is governed by the rate outlook and by duration targets. If a fund's mandate calls for a duration of five years and a rally has pushed it to seven, the manager sells long bonds to restore the target, regardless of any view on the economy. Discipline, not prophecy, drives the trade.
A corporate bond is a credit bet layered on a rate bet. Its exit may be triggered by an earnings miss, a buyout rumour, an outlook change, or a sector shock. When Moody's or S&P places an issuer on negative watch, mandate-constrained managers often must sell if a downgrade follows, because fallen angels — bonds cut to high yield — face forced selling that depresses prices further. Anticipating that cascade is a classic exit skill.
A municipal bond adds tax and liquidity to the credit bet: a market of more than $4 trillion fragmented across tens of thousands of issuers, many trading infrequently, where a sale attractive on yield alone can be poor after spreads and taxes.
The case for staying put
Here the counterargument deserves a full hearing, because the playbook can be misread as a licence to trade constantly. The evidence for patience is formidable. Vanguard, BlackRock, and other large managers have published research showing that the starting yield of a bond portfolio explains most of its return over the following five to ten years. A diversified bond fund bought at a 5 percent yield, held through volatility, has historically delivered something close to that yield over time, even if the path included sharp interim losses. The investor who exits after a rate shock, moves to cash, and waits for "clarity" often misses the recovery, because bond recoveries, like equity recoveries, tend to arrive in bursts that are hard to time.
There is a second, quieter argument for staying put: taxes and transaction costs. In taxable accounts, selling a bond at a gain triggers tax; selling at a loss can be harvested, but only if the replacement is not substantially identical and the wash-sale rules are respected. In institutional accounts, bid-ask spreads in off-the-run Treasuries and in corporate credit still bite. Mohamed El-Erian, former chief executive of PIMCO, has cautioned that investors who treat bonds like stocks — trading on every headline — surrender the very stability that justifies owning bonds in the first place.
Both warnings are valid. They refine, rather than defeat, the case for a playbook: not a mandate to sell often, but a mandate to sell deliberately, only when a trigger is hit, and to know in advance what that trigger is.
What the next regime will reward
Looking ahead, the managers best positioned for the next rate turn are unlikely to be those with the boldest forecast. They will be those with the clearest exit rules: a duration band they will not breach without committee approval, a spread floor below which credit is trimmed, a liquidity tier that separates what can be sold today from what would take a week, and a reinvestment plan for every sale.
For a wealth manager, the equivalent is simpler: a retiree holding a bond ladder needs one rule — reinvest maturities at prevailing rates, sell a deteriorating credit before a downgrade forces the issue, and let the ladder itself act as the exit strategy, since maturities arrive every year without any sale at all.
Rates will rise again, and fall again. The firms that prosper through both halves of that cycle will not be those that never sell. They will be those that sell for a reason they can state in one sentence, at a cost estimated in advance, into a replacement already identified. That is the whole playbook. It fits on a page. Executing it, year after year, is the work of a career.
