The US dollar strengthened broadly on September 14 as the continuing Middle East conflict pushed oil prices higher and investors sought the relative security of the US currency. The move came ahead of the Federal Reserve’s policy meeting, with markets preparing for the central bank’s first interest-rate increase in more than two years, while growing concerns about the pace of artificial intelligence development further weakened global risk appetite.

The combination of geopolitical uncertainty, higher energy prices and changing monetary-policy expectations is creating a more complicated environment for global currencies. For international investors, the latest move in the dollar also highlights the close relationship between energy markets, inflation expectations and capital flows.

Dollar Gains as Geopolitical Risk Drives Safe-Haven Demand

The US Dollar Index rose 0.3% to 99.41, after earlier reaching 99.735, its highest level since September 2. The advance reflected increased demand for the dollar as investors responded to uncertainty surrounding the continuing conflict in the Middle East.

The dollar’s role as a major reserve and safe-haven currency can become more prominent during periods of geopolitical stress. Investors often increase exposure to highly liquid US-denominated assets when uncertainty rises, supporting the currency even when other fundamental factors remain mixed.

The latest move therefore reflects more than a conventional currency-market adjustment. It demonstrates how geopolitical developments can rapidly alter global capital flows, particularly when they coincide with changes in energy prices and expectations for monetary policy.

Oil Prices Add to Inflation Concerns

The Middle East conflict has also pushed oil prices higher, creating an additional challenge for central banks. Energy costs have a direct influence on transportation, production and household expenses and can therefore affect broader inflation expectations.

For the Federal Reserve, a sustained rise in energy prices could complicate the process of bringing inflation toward its target. Higher oil prices can increase headline inflation even when underlying price pressures are moderating, potentially creating a more difficult policy environment for officials seeking to balance inflation against economic growth.

The energy shock also has implications for countries that depend heavily on imported fuel. For economies outside the United States, a stronger dollar combined with more expensive oil can increase the local-currency cost of energy imports, potentially adding to inflationary pressure.

Fed Expectations and AI Concerns Weigh on Risk Appetite

Currency markets are also adjusting to expectations surrounding the Federal Reserve’s first rate hike in more than two years. Higher US interest rates can support the dollar by increasing the relative return available on dollar-denominated assets, although the eventual currency impact will depend on how much of the policy change is already reflected in market pricing.

At the same time, warnings from executives at leading AI companies about the potential risks of rapidly developing artificial intelligence have weakened broader investor sentiment. The resulting pressure on technology stocks adds another layer of uncertainty to markets already dealing with higher bond yields and elevated energy prices.

For investors in Israel and globally, these developments are particularly relevant because the dollar, oil and US interest rates influence financing conditions across international markets. Emerging markets and energy-importing economies can be especially sensitive when the US currency appreciates at the same time that energy costs increase.

Looking ahead, markets will focus on the Federal Reserve’s policy decision, developments in the Middle East and the persistence of higher oil prices. Investors will also monitor whether the dollar can maintain its recent strength and whether rising energy costs begin to influence inflation expectations more broadly. A prolonged geopolitical shock could support continued safe-haven demand for the dollar, while any meaningful de-escalation could reduce that support. The interaction between monetary policy, oil prices and global risk appetite will remain central to currency-market direction in the weeks ahead.
