What Iran Conflict Could Mean for the Bond Market

Key takeaways

  • Recent geopolitical events and private credit market concerns have increased bond market volatility, influencing expectations for Federal Reserve policy and Treasury yields while raising questions about credit market spillover risks.
  • Contrary to typical safe-haven behavior, 10-year Treasury yields rose sharply after the attacks on Iran, driven by inflation expectations and a shifting federal funds outlook. We expect the 10-year Treasury yield to stay above 4%, supported by inflation and fiscal concerns.
  • We suggest that investors not overreact, favor intermediate-term maturities and higher-rated bonds, and prepare for potential short-term volatility amid uncertain economic and geopolitical conditions.

Bond market volatility has picked up following the attacks on Iran, with more questions than answers about the ultimate impact on economic growth and inflation. The attacks come on the heels of a wave of negative headlines around the private credit markets and how that might influence Treasury yields and corporate bond values.

Prior to these events, the U.S. economy appeared to be on solid footing, but the markets are likely to focus on these risks over the short run. Below we'll discuss the market reaction and potential impact on Federal Reserve policy, the direction of Treasury yields, and potential spillover to the publicly traded credit markets.

Federal Reserve policy: One or two rate cuts still likely

Coming into 2026, we expected the Federal Reserve to cut its benchmark interest rate one or two times by the end of the year, with the next rate cut likely not coming until the middle of the year. Despite signs of stabilization in the labor market, sticky inflation suggested that the Fed could take a patient approach to any policy shifts. Our view hasn't changed following the recent events in the Middle East.

We expect the Fed to continue to take a cautious view before deciding on any change in policy. Although the war in Iran is potentially inflationary, a prolonged conflict and elevated oil prices could also slow economic growth and lead to higher unemployment or tighter financial conditions. For now, elevated inflation is likely to outweigh growth concerns. Several inflation readings are still in the 2.5% to 3% range. The increase in oil prices risks inflation moving further away from the Fed's 2% inflation target. That's the view that investors generally have, as the federal funds futures market isn't fully pricing in a rate cut until the September meeting, and fewer cuts over the next year are currently priced in relative to what was expected at the end of February.
