Global Currency Markets Brace for Central Bank Decisions Amid US-Iran Tensions

Neutral (0.1)Impact: Medium

Currency markets are experiencing cautious trading ahead of a series of major central bank decisions this week, with the US Federal Reserve, European Central Bank (ECB), Bank of England (BoE), and Reserve Bank of Australia (RBA) all set to announce policy moves. The Australian Dollar (AUD/USD) has extended gains for a third consecutive day, trading around 0.7190, supported by rising expectations of an RBA rate hike. The ASX 30 Day Interbank Cash Rate Futures May 2026 contract implies a 74% probability of a rate increase to 4.35% at the upcoming RBA Board meeting, with Australia's March Consumer Price Index (CPI) report expected to show headline annual inflation at 4.7%, well above the RBA's 2–3% target range. Any upside surprise could reinforce expectations of a 25-basis-point rate hike at the central bank’s May 5 meeting [1].

Meanwhile, EUR/USD trades with mild gains around 1.1725, but upside is limited as market sentiment remains fragile due to stalled US-Iran peace talks. Iran has offered to end its closure of the Strait of Hormuz if the US lifts its blockade and ends the war, but US President Donald Trump is unlikely to accept the offer, and US Secretary of State Marco Rubio has ruled out any deal that excludes Iran’s nuclear program. These tensions are seen as potentially boosting safe-haven demand for the US dollar and acting as a headwind for major pairs. The Federal Reserve is widely expected to keep interest rates unchanged at its April policy meeting, maintaining the federal funds target range at 3.50% to 3.75%, marking the third consecutive hold. Traders await Jerome Powell’s press conference for further guidance, with a higher-for-longer stance or renewed rate hike signals likely to underpin the Greenback. The ECB is also expected to keep its benchmark deposit rate at 2.0% at its meeting on Thursday, with policymakers adopting a wait-and-see approach amid high economic uncertainty caused by conflict in the Middle East [2].

GBP/USD ended Monday largely unchanged near 1.3535, consolidating at the upper end of its April recovery. The Fed and BoE rate decisions this week are expected to set the tone for the pair through May. The FOMC is expected to hold rates at 3.50% to 3.75% on Wednesday, with Chair Jerome Powell's final meeting before his term expires May 15. March headline inflation in the US stands at a two-year high of 3.3%, and Q4 2025 GDP was revised to just 0.5%. The Senate Banking Committee is scheduled to vote on Kevin Warsh's nomination as Powell's successor on Wednesday, adding leadership-transition risk. The BoE MPC meets Thursday, with all 62 economists in a Reuters poll calling for a hold at 3.75% after March's unanimous vote to keep rates steady. The Iran conflict has reignited inflation pressures, shifting market expectations from two cuts to a split between a hold and a hike. Governor Andrew Bailey has signaled caution, noting a "very big energy shock," but previous projections suggest UK CPI inflation may drift back toward the 2.0% target through Q2. The MPC vote split (consensus 8 hold, 1 hike), Bailey's press conference, and Chief Economist Huw Pill's speech will be key UK catalysts this week [3].

Across all three major currency pairs, market sentiment remains fragile due to geopolitical tensions and uncertainty surrounding central bank policy. The closure of the Strait of Hormuz and ongoing US-Iran standoff are cited as factors limiting upside for risk-sensitive currencies and supporting the US dollar as a safe haven [1][2][3].

CONCLUSION

Currency markets are trading cautiously ahead of key central bank decisions, with geopolitical tensions adding to uncertainty. The US dollar is supported by safe-haven flows, while expectations for rate holds dominate across the Fed, ECB, and BoE. The Australian Dollar stands out on rate hike speculation, but overall market sentiment remains fragile as traders await policy signals and economic data.
