The quiet part that nobody pays attention to most of the time is that many countries - Canada, Japan, China, France, Italy, Germany - are quietly but steadily unloading their holdings of US Treasury bills.
One of the first things Mark Carney (the current Prime Minister of Canada and former governor of the Bank of Canada and Bank of England) did after taking office was to issue a large, multibillion bond in $USD. Otherwise known as shorting the US dollar (borrow in a currency, then spend that money to buy in another currency). Another thing he did was initiate a slow but steady selloff of US bonds to reduce Canada's exposure to the self-inflicted US cataclysm - and he went and met with all those other leaders to talk about exactly that process.
Right now all the other holders of US bonds - pensions, hedge funds, foreign governments - are eyeing each other nervously and unloading bonds as quickly as they can without triggering a panic. Nobody wants to be the last to panic and lose everything, all of them can see that putting a complete economic simpleton in charge of the US economy is suicide. So they are clearing out in a so-far orderly fashion. But clearing out is what is happening. Parallel to that is a clearing out of US dollar holdings in general.
The next thing to happen will be the federal reserve having to 'buy' US bonds to fund the US government deficit (and the huge tax cuts for the rich). Which in practice will mean that they are printing even more money than they do most years. In past years, other countries, hedge funds and the rest bought at least most of the bonds. Watch for nobody to be interested over the coming months, and the Fed to have to paper over that by simply creating more money.
Back in February I rebalanced my investments and ended up selling quite a but of US indices. I now regret not selling all of them.
I will predict right now that when the shoe drops and the bonds and/or dollar collapse, Trump and his sycophants will claim the US is being attacked by enemies and traitors. Because accepting the blame for something they have 100% created is just outside the realm of possibility.
