The Impact of Geopolitical Risks on the Forex Market

The closure of the Strait of Hormuz triggered the largest oil supply shock in market history in March 2026. As a result, the US Dollar Index (DXY) surged towards the 100 mark, the highest since November 2024.

However, the impact of the escalating tensions in the Middle East hasn’t been uniform. While the US dollar (USD) has strengthened, the Japanese yen (JPY) has struggled significantly. The USD/JPY hit a 20-month high on March 13, hovering near the 160 level, even as both the US and Iran remained defiant.

Given that both the USD and JPY are seen as safe havens, why this disconnect? The reason is that Japan is a net importer of crude oil. In March 2026, soaring oil prices offset the yen’s safe-haven status, as market concerns regarding a massive trade deficit for the island nation rose. 

This shift highlights one of the best risk management rules forex traders must follow at such times: Never assume historical correlations are permanent.

Central Banks Struggling to Maintain the Right Balance

Before this conflict erupted, the narrative for 2026 was one of “cautious easing,” especially for the Federal Reserve (Fed). The markets were pricing in interest rate cuts by the Fed and European Central Bank (ECB) by the summer. However, the onset of the US-Iran conflict has completely changed the script.

The Fed’s Higher-for-Longer Stance

Even until February, the markets expected the Fed to pivot towards lower rates. However, with the closure of the Strait of Hormuz in early March, energy prices have surged, reviving inflation fears. With oil prices pushing past $101 by mid-March, the Fed is now widely expected to hold rates steady in the 3.50% to 3.75% range. The higher-for-longer mantra is back, providing additional fundamental support to the USD.

The ECB and the Resilience of the Euro

Similarly, the ECB kept interest rates unchanged at its February meeting, a decision it is expected to maintain in March as well. While the Eurozone economy remains resilient, the Governing Council is wary not just of the rising geopolitical tensions but also of the ongoing uncertainty regarding global trade policy.

For a forex trader, this means the euro (EUR) might find itself caught in a tug-of-war between safe-haven flows to the USD and the domestic resilience of the European markets. This is visible in the extended decline of the currency from its February highs, with the EUR/USD dropping 5% on March 15 to reach its lowest in seven months.

Beyond the War: Other Geopolitical Headwinds

While the US-Iran situation is the headline risk, other structural factors are also at play in 2026:

Inflationary Pressures

The International Monetary Fund (IMF) estimates that every 10% increase in oil prices adds 40 basis points to global inflation. This forces central banks to remain hawkish, which in turn keeps currency volatility high.

Fragmented Trade

2026 is seeing a shift toward “national security priorities,” with increased defence spending and protectionist tariffs. This fragmentation often favours the US dollar, as the United States remains more energy-independent than its European or Asian peers.

Rise of Digital Safe Havens

Interestingly, Bitcoin has outperformed traditional assets, gaining almost 9% since the conflict began to March 17. Meanwhile, gold has seen a mixed performance.

Tips for Trading Forex Amid Geopolitical Tensions

Navigating these waters requires more than just a good eye for patterns; it requires a disciplined approach to capital preservation. Here are the core forex risk management strategies for the current climate:

Use Leverage Wisely

In a stable market, 1:50 leverage might feel safe. But with escalating geopolitical tensions, a single headline about a drone strike can move a currency pair 200 pips in seconds. Reducing your position size is the simplest way to survive a black swan event.

Widening the Stop-Loss Buffer

Volatility can lead to price jumps, which can create gaps that impact your stop-losses. Experienced traders are use wider stops with smaller positions during such times to keep their total dollar-risk the same.

Focus on Correlated Assets

Don’t just watch the EUR/USD chart. If you are trading the CAD or the NOK, you must also follow crude oil prices. Energy prices are the primary driver of currency valuations for many nations, and with the volatility fuelled by geopolitical tensions and supply concerns, your forex risk management strategies must include assessing all factors affecting forex prices.

Follow the “Friday Rule”

One of the best risk management rules for forex traders is avoiding holding large unhedged positions over the weekend. Geopolitical developments often happen on Saturdays and Sundays when the markets are closed, leading to massive gaps in asset prices on Monday morning. When assets that affect currency valuations face such gaps, your stop losses might get missed.

To Sum Up

• The USD remains the preferred safe haven, supported by rising energy prices and hawkish Fed expectations.
• High oil prices have weakened the JPY’s traditional safe-haven status due to Japan’s energy import dependency.
• Surging commodity prices are making it harder for central banks like the Fed and ECB to cut interest rates.
• Forex risk management strategies, like using leverage wisely and widening stops, are critical to surviving headline-driven volatility.
• Traditional correlations are breaking down, which means traders must adapt to a fragmented landscape, where energy security dictates currency strength.
