Federal Reserve Governor Christopher Waller warned that the ongoing conflict with Iran and the resulting blockage of the Strait of Hormuz pose significant risks to the U.S. inflation outlook. Speaking at Auburn University, Waller stated that while the central bank typically looks through temporary energy shocks, a sequence of supply disruptions could force a more aggressive policy stance. As of April 20, 2026, the critical waterway remains effectively closed to commercial traffic, despite a brief and unsuccessful attempt to reopen it over the weekend.
Waller outlined two primary scenarios for the American economy. In the first, a rapid reopening of the Strait would allow energy prices to recede, enabling the Federal Reserve to focus on a softening labor market. However, Waller emphasized a second, more worrisome scenario where an extended closure leads to high energy costs bleeding into other goods and services. He noted that the Strait handles approximately 20 percent of the world's oil supply, and its continued obstruction could cause businesses to incorporate higher input costs into their long-term pricing strategies, mirroring the inflationary shocks seen during the pandemic.
The Governor’s comments come as the Federal Open Market Committee (FOMC) prepares for its April 28-29 meeting. Market data from the CME FedWatch Tool currently indicates a 99.5 percent probability that the central bank will maintain the federal funds rate at its current target range. Waller’s speech is expected to be the final public communication from a Fed official before the mandatory pre-meeting blackout period begins. He indicated that if high inflation and weak hiring become the defining features of the economy, the Fed will have to balance the risks of its dual mandate, potentially delaying any anticipated interest rate cuts.
The geopolitical situation remains fluid. While Iran claimed on Friday that the Strait was completely open, the U.S. administration has maintained a naval blockade, leading to renewed skirmishes and the re-closure of the route by Sunday. This volatility has kept energy markets on edge, with Brent crude prices fluctuating near the 100 dollar mark. Research from the Dallas Federal Reserve suggests that an extended closure could push headline inflation above 4 percent by the end of the year, a significant jump from the 2.8 percent PCE inflation rate recorded in January.
Waller also pointed to the compounding effect of recent import tariffs, which he said make the economy more vulnerable to energy shocks. He observed that the labor market is currently in a no-hire, no-fire environment, with payroll growth showing signs of fragility. The Fed Governor concluded that the standard look-through approach to inflation becomes problematic when households and businesses begin to believe that price increases are persistent, potentially unanchoring long-term inflation expectations.
