In the real world, the US dollar via the DXY index has been VERY flat since this thread was started.
In fact, it's really been quite stable overall for the period of the 37 year chart I'm looking at, and a slow appreciation re the dominant trend, since the great recession.
https://www.marketwatch.com/investing/index/dxyAnd for the umpteenth time, since the modern Forex (foreign exchange) markets trade on the order of $5 trillion of major currencies a day, ANYONE with means and a roughly average IQ can hold their wealth in ANY major currency, basket of currencies, commodity, stock markets, real estate, etc. they want.
The power isn't in the "Petrodollar" (which is basically meaningless anyway, given that funds can be held in gold or yen or whatever and exchanged for oil at the last minute via electronic transactions).
The power is in international agreements re acceptance of payments where, say, the US and friends, can impose economic sanctions on an outfit like Russia -- and make it hurt. But that's FAR more about agreements and cooperation than the USD itself.
But of course, the instadoomer crowd like on zerobrains likes to pretend that a dollar disaster will tank the global economy overnight "real soon now", like the last 10,000 or so FALSE claims of economic calamity they've made since 2008 (when I first noticed them).
For actual credibility, they're in the FOX News category - i.e. extremely unreliable and catering to ratings and clicks more than credibility.
And it's not like gold or crypto has been going gangbusters in recent years either. The major trend for Gold has been down since Covid, and BTC has been pretty moribund for something that was supposedly going to be above $100,000 (or $200,000, $500,000, or a cool million in 2022 depending on the pumper du jure).
So much financial doom projection. So little logic.
Look, I still have the gold coins I put in my safe deposit boxes in the mid-80's, as an inflation hedge.
And it's performed meh, much like cash (but with no taxes since no interest), overall.
But the real performer over time, which ANYONE can invest in easily with just patience, is the major stock exchanges, through broad based indexes. If that's too "risky" for you, then speculating in dollar alternatives and the risk of massive long term under-performance is MUCH riskier, re probabilities of success.
Given the track record of the perma-doomer blogs, I wouldn't bet a fast crash doomer's money on their predictions.
