The Federal Reserve's Dilemma: Rising Probability of Rate Hikes and Economic Downturn Risks

By the end of February 2026, after the United States and Israel launched military operations against Iran, the situation in the Middle East deteriorated rapidly. The conflict quickly evolved from a regional confrontation into a global economic stress test, with the most critical event being Iran’s effective blockade of the Strait of Hormuz. This strait is the most vital chokepoint for global energy transportation, carrying approximately 20% of the world’s oil and a significant volume of liquefied natural gas. The blockade caused disruptions in supply chains, leading to sharp fluctuations in energy prices, a reshaping of inflation expectations, and a dramatic shift in investors’ assessments of the Federal Reserve’s monetary policy.

A few weeks prior, the mainstream market expectation was still that the Federal Reserve would implement multiple rate cuts in 2026 to counteract signs of slowing economic growth. Now, the focus has shifted to whether the Federal Reserve “might raise interest rates again.” According to market pricing, the probability of rate hikes before the end of 2026 has surged from near zero to over 20%, with some forecasts even approaching 30% to 40%. This change reflects how quickly geopolitical risks can translate into economic realities.

Strait of Hormuz blockade: a critical bottleneck for global energy and supply chains

The Strait of Hormuz, located at the exit of the Persian Gulf, is the essential route for Middle Eastern oil exports. Through military actions and threats, Iran has effectively closed passage for vessels associated with the United States and Israel, while imposing restrictions on other ships. Following the outbreak of conflict, traffic through the strait plummeted; only a few Iran-related or specially authorized vessels managed to pass, while many ships remained stranded in the Persian Gulf or were forced to reroute.

This blockade directly impacts global oil supplies. Brent crude and West Texas Intermediate (WTI) prices surged sharply at the onset of the conflict. Before the conflict, Brent was around $70 per barrel; it briefly exceeded $100 per barrel after the outbreak, even reaching the $110–$119 range. Although subsequent negotiations rumors caused some pullback, as of late March 2026, prices remained around $99–$104 per barrel, representing a cumulative increase of over 40% to 60% from the start of the year. U.S. gasoline prices also rose, with the national average surpassing $3.97 per gallon, and some regions experiencing even higher prices.

The blockade not only affects oil but also impacts key agricultural inputs such as fertilizers. The Middle East is a major hub for global fertilizer production and export, with about 20%–30% of urea, ammonia, and related products transported through the Strait of Hormuz. The blockade caused fertilizer prices to spike sharply; in the U.S., urea prices jumped 32% in a week, and ammonia prices increased by 92% compared to the same period last year. This threatens spring planting activities, as farmers face rising input costs and potential reductions in crop yields, which ultimately influence food prices.

Additionally, the strait transports industrial metals like aluminum and copper, and fluctuations in these commodities further increase manufacturing and construction costs. Rising energy prices also elevate transportation and logistics expenses, creating widespread cost-push inflation pressures.

Inflation dynamics amid oil-price shocks: from temporary to persistent risks

Traditionally, central banks tend to “look through” energy-price shocks, viewing them as temporary and causing one-off price increases rather than sustained inflation. However, the current environment is different. The U.S. economy has experienced inflation above the 2% target for several consecutive years, with consumer and business inflation expectations remaining fragile. Prolonged high oil prices could disrupt this balance.

Energy costs directly influence production, transportation, and consumption. Higher gasoline and diesel prices increase logistics costs, which in turn push up retail prices of goods. Fertilizer shortages may reduce crop yields, especially during key planting seasons in the Northern Hemisphere, triggering a global food inflation chain. Analysis indicates that if fertilizer supply disruptions persist, food prices will rise further, heightening food insecurity risks in emerging markets and affecting developed economies through import channels.

The core challenge for the Federal Reserve is the potential spillover into core inflation (excluding food and energy). If an energy shock develops into a wage-price spiral, or if firms preemptively raise prices to cover higher costs, inflation expectations could become self-reinforcing. The lessons from early-2020s misjudgments about “transient inflation” remain fresh. Fed Chair Jerome Powell and other officials emphasize the importance of closely monitoring data to avoid repeating past mistakes.

Recent data confirms market concerns: the yield on the 2-year U.S. Treasury has risen above 3.9%, surpassing the current federal funds rate target range of approximately 3.5% to 3.75%. This indicates that investors expect future interest rates to remain higher than current levels, reflecting worries about the persistence of inflation.

The Federal Reserve’s dilemma: rising odds of rate hikes versus economic downside risks

Recently, Federal Reserve officials have been cautious in their statements, avoiding explicit signals of rate hikes but acknowledging that the situation is “highly uncertain and volatile.” The latest economic projections from the Federal Open Market Committee (FOMC) still assume a baseline scenario of one rate cut in 2026, but market pricing has already shifted significantly: the probability of rate cuts in 2026 has been sharply reduced, while the likelihood of rate hikes has increased to roughly 10%–30%, depending on timing, with some points even higher.

Conditions that could trigger rate hikes include: an energy shock that sustains core inflation on an upward trajectory, combined with a resilient labor market and no significant slowdown in economic growth. Only if demand remains robust while price pressures intensify would the Fed be compelled to tighten policy further to preserve credibility and anchor inflation expectations.

However, rate hikes also entail substantial risks. Higher borrowing costs could suppress consumer spending, housing activity, and business investment, potentially pushing the economy into recession. Several institutions have already increased recession probability estimates to 30%–40%, some attributing this to elevated oil prices weighing on GDP growth. Conversely, if the Fed chooses to hold steady and allows inflation to become entrenched, it may later need to implement more aggressive tightening at a higher cost.

Political factors further complicate the outlook. Pressure from the White House to keep interest rates low could challenge the Fed’s independence, which is fundamental to its credibility. If markets perceive that monetary policy is influenced by political considerations, long-term financing costs and confidence in the dollar could suffer.

Broader global impacts and supply chain restructuring

The Hormuz crisis accelerates the global trend toward diversifying supply chains. Shipping companies are rerouting large volumes of traffic, leading to higher freight costs and delays. Countries in Asia dependent on Middle Eastern energy and fertilizers face increased pressure; some are already experiencing fuel shortages and rationing.

Disruptions in metals and chemicals also impact downstream industries such as electronics, automotive, and construction, raising costs and potentially hampering global manufacturing recovery. Over the longer term, such events may accelerate the energy transition, but in the short term, they heighten economic uncertainty.

Policy outlook and risk management

The narrative has shifted from “expectations of easy rate cuts” to “a geopolitical-driven trade-off between inflation and growth.” The Fed must act based on incoming data, closely monitoring oil prices, core PCE inflation, employment figures, and inflation expectations.

If the conflict de-escalates quickly and the Strait of Hormuz returns to normal operation, oil prices could decline, easing inflation pressures and allowing the rate-cut trajectory to remain intact. However, if the blockade persists for weeks or longer, supply shocks will be more persistent, and policy options will become more constrained. Economists generally believe that the spillover effects of energy shocks are likely to be limited and temporary, but the current fragile inflation environment increases the risk of prolonged impacts.

Overall, the crisis in the Strait of Hormuz triggered by the U.S.-Iran conflict has become one of the most significant external shocks facing the global economy in 2026. It tests energy security and supply chain resilience while reshaping monetary policy frameworks. The Federal Reserve’s response will determine whether inflation can be controlled and whether economic growth can avoid a hard landing. Investors and policymakers must prepare for multiple scenarios and remain flexible in adjusting expectations.
