Why EUR/GBP Falls Despite ECB Rate Hike Prospects

A second layer is growth differentials. The euro zone economy is showing signs of stagnation. Manufacturing weakness and a slowdown in the services sector are visible. The UK economy has avoided the same depth of contraction. Currency markets price the growth outlook as much as the policy path. A hawkish ECB paired with a deteriorating growth backdrop is a negative for the euro because it raises the risk that tighter policy will accelerate the downturn.

Risk appetite also plays a role. The euro tends to benefit when global growth expectations improve. Sterling has a more idiosyncratic driver in UK domestic policy. The current environment of cautious risk sentiment and elevated geopolitical uncertainty favours the pound's liquidity premium over the euro's cyclical exposure.

Positioning and the Next Catalyst

Positioning adds another dimension. Speculative accounts have built up long euro positions on the expectation of ECB hawkishness. When the data does not confirm the growth story, those positions become vulnerable to unwinding. The recent drift lower in EUR/GBP may reflect position squaring rather than a fundamental shift in rate expectations.

The next catalyst for EUR/GBP is the ECB policy decision and the accompanying economic projections. If the ECB delivers a hike but downgrades growth forecasts, the euro could weaken further. Conversely, a more optimistic growth outlook would challenge the current drift. On the UK side, the next CPI print will be critical. A sticky inflation number would reinforce the BoE's hold-and-wait stance and keep sterling supported.

For traders, the key is to watch the rate differential and the growth data rather than the headline rate decision alone. The simple read of ECB hawkishness equals euro strength is not holding. The better framework is to track the terminal rate gap and the relative growth momentum. Until those shift, the euro's softness against the pound may persist.
