FRANKFURT (Reuters) - A handful of European Central Bank policymakers initially wanted a larger interest-rate cut on Thursday, worried among other things that new U.S. tariffs would hamper economic growth, three sources told Reuters.

But around five of the 26 members of the Governing Council initially pushed for a 50-basis-point cut in light of lower inflation and growth forecasts.

They argued, in particular, that economic output could grow by less than the ECB-POLICY-CENTENO-a52f21b9-8975-4dc5-9a21-8c5e8267aa43>ECB-POLICY-RATES-82f6314e-6203-420b-bc8b-70a978546822>ECB-POLICY-CENTENO-a52f21b9-8975-4dc5-9a21-8c5e8267aa43>ECB's already downgraded 1.1% projection next year if Donald Trump's incoming U.S. administration imposed fresh tariffs on the European Union.
