3.17 Why the Dollar System Is Cracking

The US dollar is the world's reserve currency — most international trade, savings, and debt are denominated in dollars. That gives the US enormous power, but it also comes with a built-in problem economists call the 'Triffin Dilemma'.

In plain terms: for the rest of the world to use dollars, the US has to keep sending dollars out into the world (by importing more than it exports, year after year). But running those deficits forever eventually undermines the very currency everyone is supposed to trust. It's a slow-motion contradiction.

The dollar system got a major life extension in the 1970s with the 'petrodollar' arrangement: Saudi Arabia and others agreed to price oil in dollars in exchange for US security guarantees. Every country that wanted oil therefore needed dollars, which kept demand high.

That arrangement is now visibly cracking. China, Russia, India, and other 'BRICS' countries are openly settling oil and trade in their own currencies, gold, and other instruments. The era of universal dollar trust is ending.

Whatever replaces it has to be neutral — no single country can be in charge — and digitally portable across borders. Bitcoin happens to fit that description, which is why central banks and large investors have started paying attention.
