Foreign exchange markets are simultaneously processing a U.S. inflation print at 4.2%, the ECB's first rate hike in nearly three years, and an escalating U.S.-Iran military exchange, a combination of signals that would be challenging to interpret in isolation but together are producing a complex and volatile trading environment.

Key Highlights

  • Dollar supported by inflation and safe haven: The U.S. Dollar Index held near 99.83 on Thursday, supported by persistent inflation data pushing rate hike expectations higher, but slightly pressured by Trump's "VERY HARD TONIGHT" Iran threat, which raised risk-off concerns globally.
  • EUR/USD steady near $1.1525: The euro held relatively flat against the dollar despite the ECB's 25bp rate hike to 2.25%, as Middle East tensions continued to support dollar demand and offset the euro's rate uplift.
  • Oil-linked currencies diverge: Commodity-exporting currencies including the Canadian dollar and Norwegian krone have seen relative support from elevated oil prices, while energy-importing economies face currency depreciation pressure from worsening terms of trade.
  • Treasury yields move sharply: The U.S. 10-year Treasury yield held near 4.53% and the 2-year at approximately 4.09%, with the yield curve reflecting both persistent inflation and uncertainty over the Fed's next move.

Three simultaneous macro signals arrived in global currency markets on Thursday, each pointing in different directions and requiring traders to weigh competing forces with unusual care. The result was a session characterised by contained moves in major pairs despite an underlying environment of significant uncertainty.

U.S. consumer prices rose 4.2% year-on-year in May, while producer prices climbed 6.5%, both above forecasts. The data reinforced market expectations that the Federal Reserve will hold rates steady at the June 16-17 FOMC meeting but raise them later in the year, with the CME FedWatch tool showing approximately 70% probability of at least one hike before year-end 2026. Dollar strength from rising rate expectations provided one source of support for the currency.

At the same time, the ECB raised its deposit facility rate by 25 basis points to 2.25%, its first increase since September 2023, citing rising energy-driven inflation and upside risks to its 2% target, which it does not expect to reach until 2028. In principle an ECB hike is euro-positive, but the euro failed to gain meaningfully, as persistent geopolitical risk kept demand for the U.S. dollar elevated.

The third signal, escalating Iran hostilities, added further complexity. Trump's threat to strike Iran and seize Kharg Island sent oil prices higher and equity markets lower at points during the session, generating safe-haven flows into the dollar and Treasury bonds before stabilising.

Oil-linked currencies including the Canadian dollar and Norwegian krone have maintained relative resilience, benefiting from improved terms of trade for energy exporters, while currencies of energy-importing economies face pressure from rising crude import costs.
