Markets have largely priced in a European Central Bank (ECB) rate rise in June, framing the move as more symbolic than a shock. Expectations for additional tightening later this year have softened as hopes of a resolution to the Iran conflict have grown, and the prospect of the Strait of Hormuz reopening in the coming days is presented as insufficient to deter a June hike.
Under a scenario in which the Middle East situation does not re-escalate and second-round effects fail to appear, the ECB is described as likely to stop after this single step, with the focus shifting from the size of the move to the bank’s reaction function. The implied increase is 25 basis points, and the argument is that this limits the scope for a longer-term repricing that would weigh on the euro; in the near term, an end to the war in Iran is associated with a weaker US Dollar (USD), firmer Eurozone growth sentiment and broadly steady ECB rate expectations.
ECB Rate Hike Expectations and Market Reactions
We believe the European Central Bank’s expected interest rate hike on June 11th is already reflected in current market pricing. Overnight index swaps show a 95% probability of a 25 basis point increase, so the event itself is unlikely to cause significant new volatility. The real focus for the coming weeks should be on geopolitical developments in the Middle East.
An end to the Iran conflict would be the primary catalyst for a stronger Euro. The potential reopening of the Strait of Hormuz has already caused Brent crude prices to pull back from over $115 to around $102 a barrel, which would ease inflation and growth concerns in the energy-dependent Eurozone. This relief for the European economy would likely attract investment flow into the region.
Implications for Currencies and Trading Strategies
At the same time, a de-escalation of conflict would weaken the US Dollar’s safe-haven appeal, a dynamic we have seen before. For instance, an easing of global tensions in late 2022 led to the Dollar Index (DXY) falling by over 8% in two months. We anticipate a similar, though perhaps less pronounced, move if a resolution is formally announced.
For derivative traders, this outlook suggests positioning for a rise in the EUR/USD exchange rate. With one-month implied volatility still elevated near 9.8% on the uncertainty, we see value in buying EUR/USD call spreads with a July expiry. This strategy captures the potential upside from a weaker dollar and a more stable Eurozone while helping to offset the current high cost of options.
