On a trade weighted basis it’s more like 3%-4%. The US is indeed lower on average, but marginally by like 1-2% on average.

But I think the concern is more key industries for the US like autos, tech (EU never ending fines are essentially tariffs), etc. where the disparity is more dramatic. But it’s still not a 20% difference.

Another concern is the devaluation of the Euro vs the dollar due to certain economic policies. Which again is a defacto tariff.

Anyways, my guess is this is a negotiating position since 20% seems excessive, but I could be wrong.
