In the weeks after U.S. and Israeli forces struck Iran on February 28, 2026, government bonds delivered a punishing performance. Prices fell, pushing yields sharply higher and handing investors negative returns. Yet during that same period, according to Lipper data, a net $12 billion flowed into developed-market government bond funds—the entirety of the year's inflows . It's a paradox rooted in a collision of inflation panic, income hunger, and a conviction among some of the world's largest asset managers that the bond market was misreading the future.
Why investors bought bonds that were losing money
The selloff itself created the entry point. As inflation fears from the oil shock repriced interest rate expectations, yields on government debt surged to levels that had not been seen in years—and in some cases, in decades.
Income buyers arrived: The sharp price decline was, as Raymond James put it, an "unexpected positive for income-buying clients" who had been starved for yield . Pension funds, insurers, and retail yield-seekers used the selloff to lock in higher income streams.

Institutional dip-buying: For many professional allocators, a deep drawdown in high-grade sovereign debt is a rare re-entry point, especially after bonds had rallied earlier in 2026 before the conflict began .
Rotation from cash: Early in the war, investors fled to the safety of money market funds. Global money market funds absorbed $47.9 billion in the first week of March alone . As the conflict wore on, some of that cash rotated into longer-duration government bond funds to capture the elevated yields.
The contrarian case: three arguments for buying the selloff
Money did not just chase higher yields; it followed a deliberate thesis that bonds would regain their footing—and possibly surge.
1. Peak-inflation expectations
The immediate market reaction was a repricing of central bank rate expectations. Brent crude leaped from roughly $72 to $119 per barrel during March, stoking fears of persistent inflation and pushing rate cuts out to late 2026 or 2027 . But by mid-2026, a growing number of fund managers argued that the inflation impulse was peaking. Supply shocks dissipate eventually, and the war's drag on global growth would overtake the energy-price spike. Some investors now see bonds regaining their traditional safe-haven role as inflation erodes economic activity .
2. Multi-decade high yields
The selloff created historically attractive entry points across major sovereign markets.
Japan: The 10-year Japanese government bond yield hit 2.80% in May 2026, its highest level in 29 years, while the 30-year yield reached 3.79% and the 40-year touched 4.02% . For a market that has lived with near-zero yields for decades, these levels are transformative.
Europe: German Bund yields climbed to 3.07%, restoring the viability of euro-denominated government debt for yield-seeking portfolios.
United States: Treasury yields jumped across the curve. The 10-year yield rose from 3.97% to 4.31% during March alone, drawing in buyers who had been waiting for a more attractive entry point .
3. PIMCO and JPMorgan: the slowdown trade
The most prominent institutional expression of the contrarian view came from PIMCO. Andrew Balls, the firm's chief investment officer for global fixed income, revealed in April that PIMCO had moved from an underweight to an overweight position in European government bonds, adding exposure in its global bond funds . He cited a mispricing created by the unwinding of previously crowded trades.
A few weeks earlier, PIMCO and JPMorgan made a joint argument that the bond market was underestimating the risk of a global slowdown . The logic is straightforward: if recession fears overtake inflation fears, bonds will rally sharply. At current yields, the payoff for being right is substantial. PIMCO's broader position is that "globally, fixed income markets look very appealing" because the recession scenario remains underpriced .
The Strait of Hormuz wildcard
At the center of every scenario is a single chokepoint. Iran's effective closure of the Strait of Hormuz—a waterway that carries roughly one-fifth of the world's oil supply—jammed the transportation route for oil consumed by more than 30 countries and sent crude prices surging by roughly 83% .
The outcome is binary in ways that both favor bondholders:
If the Strait reopens fully, as Iran's foreign minister claimed during the April ceasefire, oil prices could collapse, easing inflation and reversing rate-hike expectations. Markets surged on exactly that scenario in April .
If the disruption persists, the sustained oil shock deepens the risk of a global recession. Morgan Stanley laid out scenarios in which extended high energy costs crush demand . In a recession, bonds reassert their traditional safe-haven role, and investors buy for capital preservation regardless of current yields.
The April ceasefire initiated peace talks and relieved some yield pressure, but the underlying outcome remains unresolved as of June 2026. As long as the Strait remains a live uncertainty, the binary risk—reopening equals disinflation, closure equals recession—keeps both sides of the contrarian bond trade intact.
What the flow data reveals
The scale of the repositioning extends beyond the $12 billion headline figure. Sovereign wealth funds redirected capital; one Middle Eastern fund reportedly shifted an estimated $15 billion into U.S. and European government bonds from speculative tech positions . Global bond funds attracted another $19.6 billion in one reporting period alone as investors trimmed corporate credit exposure and accepted government duration risk . PGIM noted that the anxiety of the first quarter had pushed government yields and credit spreads to levels that "bode well for returns over the long term" .
For the contrarians, the math is simple: starting yields are the single best predictor of future bond returns. The selloff may have inflicted short-term losses, but it also reset the starting point for forward-looking returns at a level that institutions like PIMCO, PGIM, and Franklin Templeton consider unusually attractive. Whether the trade ultimately works depends on a single unresolved variable—a narrow strip of water between Iran and Oman.
