Military actions by the US and Israel against Tehran have entered their third week, with a recent attack setting an oil storage facility ablaze, sending thick smoke into the sky as local residents watched and documented the scene. This conflict has effectively dashed any remaining hopes for Federal Reserve interest rate cuts this year.

The war has triggered the most severe oil supply disruption in history, driving up energy prices and placing upward pressure on the cost of nearly all US consumer goods. Concurrently, investors and Fed officials are still assessing the full inflationary impact of President Trump's tariff policies.

The Federal Reserve currently anticipates only one rate cut this year, projected at 25 basis points, with updated forecasts due for release on Wednesday. However, as the conflict persists, any potential rate reduction is likely to be pushed further into the future.

"While the Fed typically looks past oil price shocks, we would be fortunate to get even one rate cut this year," wrote Rick Gardner, Chief Investment Officer at RGA Investment Company, in a recent analyst note. "Even if a cut happens, it will most likely be delayed until late in the year, when a new Fed Chair will be in place and more data on inflation and employment will be available for assessment."

In January, Trump nominated Kevin Warsh to succeed Chair Jerome Powell when his term concludes in May. If confirmed by the Senate, Warsh is expected to favor lowering borrowing costs. However, the war with Iran is likely to disrupt this strategy.

Following this week's meeting, Powell theoretically has only one more opportunity to chair a meeting. Nevertheless, he could remain in the role if Republican lawmakers fail to secure the support of North Carolina Senator Thom Tillis for the new chair nomination. Tillis has stated he will block all Fed-related nominations unless the Trump administration halts its investigation into Powell's handling of the Fed headquarters renovation project.

The situation is growing increasingly complex. In April of last year, Trump imposed a series of punitive tariffs on all US trading partners. Many economists argued these tariffs would raise costs for American businesses and individuals. Although prices for many imported goods rose after the tariffs were implemented, previously lower energy costs largely offset this increase. The war with Iran now appears to be eliminating that buffer.

Even though the Supreme Court struck down most of Trump's tariff policies in January, he quickly introduced a new policy: a global 15% tariff on all goods entering the United States.

Several Fed officials, including Powell, have suggested that Trump's tariffs would ultimately lead to a one-time increase in price levels. Now, central bank policymakers must also evaluate how this increase interacts with the economic repercussions of the Middle East conflict.

"We were already facing significant uncertainties," explained Chicago Fed President Austan Goolsbee in a March 6th interview, noting that the current oil crisis makes it more difficult to distinguish tariff-induced inflation. "The movement in energy prices and the effects of the tariffs will compound each other," he said.

The economic impact of the war largely depends on its scope and duration. Experts indicate that the current disruption to global energy markets exceeds any in modern history, including the 1973 Arab-Israeli War, which led to a years-long oil crisis in the US. Currently, there are few signs of the conflict ending, with Iran escalating attacks on energy infrastructure across the Middle East.

"We need to observe the persistence of this effect," New York Fed President John Williams told reporters at an event in Washington D.C. on March 3rd, referring to the global energy shock. "The key questions are the magnitude of the impact on the United States and how long the effects on price stability will last."

This complex economic landscape once again places Fed officials in a difficult position. They must weigh the dual threats to their mandate of price stability and maximum employment, deciding which risk to prioritize.
