The US Dollar may be on the decline, but nobody can say whether it has a few months, years, or decades before it collapses. Right now, the increase in interest rates is making it attractive for global investors who are buying US bonds. The USD has appreciated in value against most global currencies over the past few months.
No one has the timeline for sure. Calls for doomsday have been made since the 2008 financial crisis. But we do see it coming miles away. and It will happen. Within the next five years, imo. One thing is for sure, it's a bigger bubble and we can't really have negative interest rates this time around to reinflate that bubble.
