Lower than their 2024 peak, but still much higher than before 2022 where for a long period it was at 0% or even negative interest (apparently, I don't know much about these things). It's at 2% or 2.4% at the moment, last time it was around that was in 2008. See https://www.ecb.europa.eu/stats/policy_and_exchange_rates/ke...

But I'm no economist and don't know what these numbers mean or what the consequences are.

In general lower interest rates would cause your currency to depreciate.

Which would mean that the Euro would depreciate significantly against the dollar under normal circumstances.

Yet the Euro increased by > 10% despite the ECB cutting the rates quite significantly. Imagine how low the dollar would go if the Fed listened to Trump and cut to 1%..
