Global currency markets are reacting to weekend military strikes involving the United States, Israel, and Iran that resulted in the death of Iran's Supreme Leader. Safe-haven currencies like the Swiss franc and Japanese yen are strengthening while investors worry about potential oil supply disruptions and broader economic impacts.

Currency markets opened Monday with significant shifts as investors responded to escalating Middle East tensions following weekend military operations between the United States, Israel, and Iran that resulted in the death of Supreme Leader Ayatollah Ali Khamenei.
The Swiss franc and Japanese yen, both considered safe investments during times of uncertainty, strengthened as global markets reopened. Meanwhile, the euro declined 0.34% to $1.1776, down from approximately $1.18 during Friday’s late New York trading session. The European currency also dropped 0.5% against the Swiss franc to 0.9039, marking its weakest position since 2015.
The U.S. dollar weakened by 0.26% to 155.65 yen and fell 0.3% compared to the Swiss franc, though it gained ground against both the British pound and Australian dollar.
The military actions and subsequent Iranian counterattacks have created widespread concern throughout the Middle East region, impacting industries ranging from shipping and aviation to energy markets. Businesses operating in the Gulf region, a crucial global trade corridor, are bracing for potential disruptions and increased operational costs.
Energy market reactions will likely determine how stocks, bonds, and currencies respond to the unfolding situation in Iran going forward.
Market analysts anticipate oil prices will surge significantly when trading begins Monday, with over-the-counter markets already showing increases of approximately 10%. Gold, another traditional safe-haven investment, is expected to rise sharply while stock markets are projected to decline.
Regional stock exchanges felt the impact Sunday, with most Gulf markets falling and Boursa Kuwait halting operations entirely after Iranian retaliatory strikes targeted American installations in nearby Gulf cities, heightening concerns about extended regional conflict.
Currency markets were among the first to respond to weekend developments as investors worked to assess potential outcomes from the escalating situation.
“We see two scenarios: first, contained disruptions to global energy markets, with limited implications for the world economy. Second, a more protracted, broader conflict leading to an oil shock,” explained Lombard Odier chief economist Samy Chaar.
“We believe that the first case is playing out right now,” Chaar noted, while warning that in a more severe scenario, “commodities, bond yields, currencies, oil-sensitive equity sectors, inflation expectations, monetary policy paths – and in case of a protracted closure (of the Strait of Hormuz), economic growth – would all be affected.”
Brent crude oil prices jumped 8% to 10% higher at approximately $80 per barrel in over-the-counter trading Sunday, according to traders. Oil prices had already climbed Friday to $73, reaching their highest level since July.
Iran plays a significant role in global energy production and sits across from the oil-rich Arabian Peninsula, separated by the Strait of Hormuz. This strategic waterway handles roughly 20% of worldwide oil shipments.
