The U.S. dollar has come under pressure amid soaring energy prices triggered by the U.S.-Israel war on Iran. The greenback slipped from multi-month highs this week as rising oil and gas costs disrupted expectations for global interest rates, leaving the U.S. Federal Reserve as the only major central bank not expected to raise rates this year.
“The Fed is signalling a longer pause if inflation stays sticky; the ECB is opening the door to insurance hikes,” said Wei Yao, global chief economist and head of Asia-Pacific research at Societe Generale, in a note to clients.
According to Reuters, investor expectations have shifted significantly since the conflict began at the end of February. Before the escalation, markets anticipated two Federal Reserve rate cuts this year; now, even a single cut appears increasingly unlikely. At the same time, the outlook for other major central banks has turned more hawkish, and at a faster pace.

This divergence has created mixed pressures on the dollar. On one hand, rising global uncertainty typically supports the currency. On the other, relatively tighter monetary policy abroad is making other currencies more attractive to investors.
“The longer the war drags on, the higher the U.S. dollar will go, because it will benefit from safe-haven demand arising from higher uncertainty (and) also from the U.S. being an energy exporter,” said Carol Kong, currency strategist at Commonwealth Bank of Australia.
At the same time, surging oil and natural gas prices have intensified inflation concerns globally. Central banks such as the European Central Bank and the Bank of England have signaled potential rate hikes to contain inflation. This shift has weakened the dollar relative to other currencies, as investors look toward markets where returns may rise more quickly.
The euro, yen, sterling, Swiss franc, and Australian dollar are all heading for weekly gains against the dollar, as policymakers lay the groundwork for higher interest rates in response to supply disruptions stemming from the Middle East conflict.
Sudden geopolitical shocks, particularly in key energy-producing regions, can ripple across financial systems, influencing exchange rates, investor sentiment, inflation expectations, and central bank strategies.
Reuters reports that benchmark Brent crude futures have surged nearly 50% since the U.S. and Israel attacked Iran, a development that has severely disrupted a critical sea lane for Middle East energy exports.
These market movements also highlight the central role of monetary authorities in stabilizing economies during periods of uncertainty. Diverging policy responses, shaped by regional economic conditions and external shocks, can create both risks and opportunities for investors and businesses alike. Currency movements, in this context, are driven not only by economic fundamentals but also by perceptions of risk, policy credibility, and broader market sentiment.

Energy markets remain a key factor in this dynamic. Sharp increases in oil and gas prices can amplify inflation, shift trade balances, and alter growth trajectories. Policymakers must weigh short-term stabilization measures against long-term resilience, particularly when faced with unpredictable geopolitical developments.
These developments illustrate the complexity of global financial systems and the need for adaptability among investors, governments, and businesses. Understanding the interplay between geopolitical events, commodity markets, and monetary policy is essential for anticipating market trends and mitigating risks in an increasingly interconnected world.
