I believe the war in Ukraine has permanently damaged the USD's dominance in the medium to long term.

The use of a supposedly neutral financial network (SWIFT) as a sanction weapon will make other nations who aren't on good terms with the U.S. and the West (and not just the "usual suspects" but many nations in Africa and South America too) seeking alternatives.

As previously mentioned, Bitcoin is a viable alternative. But there may be others. In any case I see nations ganging up to create an alternative to the SWIFT network, potentially undermining its usefulness.
