US-Iran Deal Buys Fed Time: Former Dallas Fed President Kaplan on Rate Outlook

US-Iran Tensions Ease, Giving Fed Breathing Room: Former Dallas Fed President Kaplan Weighs In

Recent diplomatic progress between the United States and Iran over the nuclear issue is being viewed by markets as a potential positive signal. Former Dallas Federal Reserve President Robert Kaplan said in an interview that a potential US-Iran resolution would give the Fed valuable "breathing room" before its next rate decision. This view has prompted Wall Street to reassess the monetary policy path.

Geopolitical Risk Declines, Inflation Pressure May Ease

Kaplan noted that if the US and Iran can resolve differences through diplomacy, Iranian crude oil exports could increase, helping to ease supply tightness in global energy markets. According to a previous report by the International Energy Agency (IEA), Iran has about 4 million barrels per day of spare capacity. If sanctions are relaxed, the release of this capacity could push down oil prices, thereby reducing imported inflation pressure. For the Fed, this means one less upside risk factor to consider when assessing whether inflation is sustainably declining.

"If geopolitical risks decline and energy prices stabilize, then the Fed won't feel pressured to take more aggressive tightening measures," Kaplan said during a recent online seminar. He believes this provides a window for the Fed to observe more economic data and wait for further cooling in the labor market and core services inflation.

The Logic of "Trading Time for Space" in Rate Decisions

Currently, market expectations for a Fed rate cut in 2025 remain divided. Some investors worry that if inflation proves stickier than expected, the Fed may be forced to keep rates higher for longer. Kaplan's view offers a middle-ground perspective: supply-side improvements from a US-Iran rapprochement could allow the Fed to adjust policy more comfortably without sacrificing employment goals.

"This is essentially a strategy of 'trading time for space,'" Kaplan added. He explained that Fed Chair Jerome Powell has repeatedly emphasized a "data-dependent" approach. If external shocks (such as a spike in oil prices) are eliminated, domestic economic data—especially wage growth and rents—will become the key drivers of the rate path. This reduces the risk of the Fed having to make hasty rate adjustments due to unexpected events.

Potential Impact on US Stocks

From a US equity perspective, this logic is positive for several sectors. First, lower energy costs directly benefit heavy oil users such as airlines, transportation, and manufacturing, improving their profit margins. Second, stable rate expectations help tech growth stocks' valuation recovery, as reduced long-term rate volatility lowers discounting pressure on high-valuation stocks. Additionally, a fading geopolitical risk premium typically boosts overall market risk appetite, driving funds from safe-haven assets (like the US dollar and gold) back into equities.

However, Kaplan also cautioned investors to remain prudent. He noted that US-Iran negotiations remain uncertain, and even if an agreement is reached, it will take time for Iranian oil to return to the market. Moreover, the Fed's final decision still depends on key indicators such as core PCE (Personal Consumption Expenditures price index). Therefore, markets should not overbet on a single event.

Summary: A Positive "Cushion"

Overall, former Dallas Fed President Kaplan's analysis provides a valuable framework for the current market: US-Iran diplomatic progress does not directly determine the rate path, but it creates a more favorable decision-making environment for the Fed. For US stock investors, this means near-term rate risk has decreased, but the long-term focus remains on economic fundamentals and inflation data evolution. As Kaplan put it: "This is not the finish line, but a cushion that allows the Fed to reach the finish line more comfortably."
