Yet the article does not explain how a "gas crisis" leads to a weaker currency.

And the ECB has done basically nothing about it. Deeply negative real rates and little indication that the ECB has the stomach for any substantive action.
On the US side, there have been sizable interest rate hikes, which will continue at least until the midterm elections get underway. Real rates are still deeply negative.
That difference in rates attracts a lot of capital that might otherwise be parked on the EU side.
The US doesn't need to be a pillar of financial responsibility to attract the world's capital. It just has to be the cleanest dirty shirt in the hamper.
