The Chinese government’s ban of cryptocurrencies is a sign of weakness. From Eric Peters at zerohedge.com:
“Is it your intention to ban or limit the use of cryptocurrencies, like we’re seeing in China?” asked Ted Budd, Republican congressman from North Carolina. “No,” replied Fed Chairman Jay Powell. “No intention to ban them?” asked Budd again. “No intention to ban them, but stablecoins are like money market funds, they’re like bank deposits; they’re to some extent outside the regulatory perimeter, and it’s appropriate that they be regulated,” answered Powell. And as it sunk in that the world’s largest economy would not chase China to stifle private sector innovation in the field of blockchain technology, digital assets prices surged
The US dollar is the world’s reserve currency. 59.2% of all official foreign exchange reserves are held as US dollars. 20.5% are euros. 5.8% are Japanese yen. 4.8% are British pounds sterling. 2.6% are Chinese renminbi — slightly more than the 2.2% of reserves held in Canadian dollars. 1.8% are Australian dollars. The remaining few percent are various other small currencies that don’t matter in the grand scheme of things. Swiss francs would be an example. Some reserves are held in gold. Someday, there will be digital asset reserves too.
For a foreign nation to hold dollars in reserve, it must first acquire them. It can either purchase those dollars in foreign exchange markets, or it can acquire the dollars by selling its goods, services, hard assets, or financial assets. There are consequences to such transactions. One of them is that the dollar’s value relative to other currencies is higher than it would be if these nations were not buying and holding dollars in reserve. Another is that by acquiring so many dollars and holding them in reserve, the US is forced to run a current account deficit.
