A surge in geopolitical tensions in the Middle East, specifically the ongoing conflict involving the US and Iran, has triggered significant volatility across global financial markets, with pronounced effects on currency and energy markets [1][2][3][4][5]. Oil supply fears have pressured the Japanese Yen (JPY), as Japan relies heavily on imported energy from the Middle East. The USD/JPY pair climbed to around 158.82, approaching levels seen before a 'rate check' on January 23, as the US Dollar (USD) strengthened on the back of firm Treasury yields and in-line US inflation data [1]. The Consumer Price Index (CPI) in the US rose 0.3% MoM in February and 2.4% YoY, with core CPI at 2.5% YoY, reinforcing expectations that the Federal Reserve (Fed) will maintain a cautious policy stance as inflation remains above its 2% target [1][2][3].
The conflict has also led to heightened risk aversion, weighing on risk-sensitive currencies such as the New Zealand Dollar (NZD), which traded lower at 0.5910, down 0.38% on the day [2]. Market analysts now expect more persistent inflation in New Zealand, with increased expectations for Reserve Bank of New Zealand (RBNZ) rate hikes this year, a shift from previous guidance that the Official Cash Rate could remain at 2.25% [2]. Meanwhile, the Pound Sterling (GBP) remained steady near 1.34 against the USD, despite the oil shock and elevated US inflation, as traders balanced Middle East risks with steady US CPI data [3]. Oxford Economics estimates UK inflation could be 0.4% higher if the Strait of Hormuz remains shut for up to two months [3].
In Europe, ECB Executive Board member Isabel Schnabel emphasized the need to monitor the persistence of the energy price shock and remain vigilant to upside inflation risks, noting that March projections will partly reflect the Iran shock [4]. French President Emmanuel Macron stated that France will engage with other countries to limit export restrictions and may decide on further measures to cushion oil price increases for French consumers. France's release of strategic reserves represents 14.5 million barrels, and G7 nations have backed the IEA's coordinated release of 400 million barrels to ease supply disruptions [1][5]. Macron also noted that it will take a few weeks to coordinate Hormuz ship escorts [5].
Currency heat maps across the sources consistently show the Japanese Yen as the weakest among major currencies, while the Euro and US Dollar have gained ground, reflecting the market's risk-off sentiment and preference for safe-haven assets [1][2][4][5]. Market participants trimmed bets on a Fed rate cut in 2026 following the CPI release, with money markets expecting 30 basis points of easing toward December [3]. In contrast, a Reuters poll indicated that the Bank of Japan is widely expected to keep its key rate unchanged at 0.75% at the March 19 meeting, though 60% of economists expect a rise to 1.00% by the end of June [1].
Forward-looking statements from central bankers and government officials highlight ongoing uncertainty. The Fed is expected to remain cautious, the ECB is vigilant about upside inflation risks, and the French government may introduce further measures to shield consumers from oil price shocks [1][4][5]. US President Donald Trump suggested the war with Iran could end soon, but this contrasts with other US officials who indicate intensifying military operations, leaving the market outlook uncertain [1][2].
CONCLUSION
Escalating Middle East tensions and oil supply fears have driven significant volatility in currency and energy markets, strengthening the US Dollar and pressuring risk-sensitive currencies and the Japanese Yen. Central banks and governments are responding with cautious policy stances and potential interventions, while inflation risks remain elevated. The market impact is high, with ongoing uncertainty likely to sustain volatility in the near term.
