Singapore, 9 March 2026 – The US dollar strengthened against major global currencies as escalating conflict involving Iran sent shockwaves through financial markets, pushing oil prices sharply higher and triggering a wave of risk aversion among investors.
The surge in the greenback comes as global markets react to the widening geopolitical crisis in the Middle East, which has driven crude oil prices above US$100 per barrel and intensified fears of inflation and economic disruption.
Safe-Haven Demand Lifts the Dollar
Currency markets moved swiftly as investors sought safety in the world’s reserve currency. The US dollar strengthened against all major peers, including the euro, Japanese yen, British pound and commodity-linked currencies.
Analysts say the rally highlights the dollar’s continued role as the dominant safe-haven asset during periods of geopolitical instability. As markets become more volatile, global investors often shift capital toward highly liquid assets such as US Treasury securities and the dollar itself.
At the same time, rising oil prices have added another layer of support for the US currency. The United States is one of the world’s largest oil producers, and higher energy prices tend to reinforce the dollar’s strength relative to many other currencies.
Oil Shock Ripples Across Financial Markets
The conflict has triggered one of the sharpest oil rallies in recent years. Brent crude and US benchmark crude have climbed above US$108 per barrel, the highest levels since 2022, as military strikes and retaliatory actions disrupt energy supply routes in the Middle East.
A key concern is the Strait of Hormuz, a vital maritime chokepoint through which roughly 20% of the world’s oil supply passes. Any disruption to tanker traffic through the strait could significantly tighten global energy supplies and send prices even higher.
Some analysts warn that oil prices could climb toward US$150 per barrel if the conflict escalates further or if shipping routes remain restricted for an extended period.
Global Stocks Slide Amid Rising Inflation Fears
The energy shock has triggered broader turmoil across global financial markets. Equity markets in Asia and the United States have retreated as investors reassess the economic impact of rising oil prices and the possibility of slower global growth.
Higher energy prices can act as a tax on the global economy, raising production costs and consumer expenses. Economists warn that a sustained spike in oil prices could reignite inflation pressures worldwide and complicate central bank policies.
Central banks had previously been preparing for potential interest-rate cuts as inflation eased in many economies. However, a new inflation shock driven by energy prices could delay those plans and force policymakers to maintain tighter monetary conditions for longer.
A New Phase of Market Volatility
The geopolitical escalation has underscored how quickly global markets can shift when energy security becomes uncertain. Commodity prices, currencies and equity markets are now moving in tandem with developments in the Middle East conflict.
For investors, the strengthening dollar and rising oil prices signal a broader shift toward defensive positioning in global portfolios.
Whether the current market turmoil proves temporary or evolves into a longer-term economic shock will largely depend on how the geopolitical situation unfolds, particularly the stability of energy supply routes through the Persian Gulf.
