PIMCO Says Rising Inflation Expectations Could Force Central Banks to Tighten Policy

Firm cautions that unanchored long-term inflation expectations would push rates up and strain risk markets

By Nina Shah

Pacific Investment Management Co.'s chief investment officer Daniel Ivascyn warned that if long-dated inflation expectations become meaningfully unanchored, major central banks including the Federal Reserve may need to tighten monetary policy even amid economic weakness. The dynamics have already pushed breakeven inflation measures and long-term Treasury yields higher, while corporate credit and equities have so far shown resilience.

PIMCO Says Rising Inflation Expectations Could Force Central Banks to Tighten Policy

Key Points

  • PIMCO CIO Daniel Ivascyn warns that unanchored long-term inflation expectations could force central banks to tighten policy, raising interest rates and pressuring equities and credit.
  • Treasury breakeven inflation measures climbed to their highest levels in over three years after oil surged following a US attack on Iran in late February, and the US 30-year Treasury yield reached its highest level since 2007.
  • Despite bond market repricing that nearly reflects a quarter-point Fed hike by year-end, corporate credit and equities have remained relatively resilient; PIMCO recommends disciplined interest rate risk management and sees high-quality fixed income yielding 6% to 7% over a multi-year horizon.

Pacific Investment Management Co.'s chief investment officer, Daniel Ivascyn, warned that major central banks could be compelled to tighten monetary policy if inflation expectations at the long end of the curve rise materially.

"If long-dated inflation expectations become more significantly unanchored, then you are going to see a tightening of policy even in the face of some economic weakness," Ivascyn said. He added that such a policy response would tend to lift interest rates and increase stress on equities and credit markets.

The warning arrives as leadership at the Federal Reserve changes hands. Incoming Fed Chair Kevin Warsh is set to assume the role this month after President Donald Trump campaigned for lower interest rates. The central bank has kept its policy rate unchanged so far this year, but officials have shown increasing divisions over the appropriate stance. At the April meeting, policymakers noted upside risks to the near-term inflation outlook while stating that longer-term inflation expectations remained well anchored.

Market measures of inflation expectations have moved notably. Treasury market inflation expectations, captured by breakeven rates, recently climbed to their highest levels in more than three years after oil prices jumped following a US attack on Iran in late February. That move helped trigger a sharp selloff in global bond markets and pushed the US Treasury 30-year yield this week to its highest level since 2007.

Those Treasury inflation benchmarks now sit at levels last observed in March 2023, a period when the Fed was raising rates to counter post-pandemic inflation and an energy shock tied to the Russian invasion of Ukraine. The US 10-year breakeven has traded above 2.5%, up from roughly 2.2% at the start of the year.

Despite these shifts in fixed income markets, corporate credit and equities have so far demonstrated relative resilience. Bond traders have nevertheless been repricing expectations for tighter policy: swap contracts are close to reflecting a quarter-point Federal Reserve rate increase by year-end.

Ivascyn said that a firmer commitment to fighting inflation could, paradoxically, stabilize long-term rates by convincing markets that central banks will prevent inflation expectations from drifting upward. He also suggested that the level of tightening currently implicit in market pricing may be excessive.

PIMCO, which manages $2.3 trillion in assets, said it retains a disciplined stance on interest rate risk. Over a three-year horizon the firm is comfortable with its interest rate exposure, and Ivascyn noted that investors can construct high-quality fixed income portfolios yielding in the 6% to 7% range.

On the macroeconomic outlook, Ivascyn highlighted a historical pattern linking energy shocks to recessions. He said that the longer elevated oil prices and heightened inflation expectations persist, the greater the probability markets will assign to a recession. Such a shift in recession odds could translate into lower equity valuations, wider credit spreads and lower bond yields.

Risks

  • If long-dated inflation expectations become more significantly unanchored, central banks may tighten policy even amid economic weakness, which could depress equities and widen credit spreads - affecting equity and corporate credit sectors.
  • Sustained higher oil prices and elevated inflation expectations would increase recession probabilities, potentially leading to lower equity valuations, wider credit spreads, and lower bond yields - impacting energy-sensitive sectors, financials, and fixed income markets.
  • Market pricing may already incorporate substantial tightening; if that pricing proves excessive or shifts abruptly, volatility could rise across bond, equity and swap markets - affecting institutional fixed income portfolios and funding-sensitive firms.
