COFA data reveals a significant multi-year trend where a bloc of unspecified "other currencies" is steadily gaining share in global reserves. This group has displaced more of the US dollar's declining share than the Euro, Yen, or Sterling, indicating a broad, under-the-radar diversification movement by reserve managers.

The dollar's decline, particularly in April, was not driven by investors divesting from US assets. Instead, it was caused by investors with large, unhedged dollar exposures belatedly adding hedges. This involves selling dollars in the spot or forward markets, creating downward pressure without actual asset sales.

The US Federal Reserve's money printing functions as a global tax through the Cantillon effect. The first recipients of new money (government, large banks) benefit before inflation spreads. This silently dilutes the wealth of all other dollar holders, both domestically and internationally, effectively transferring purchasing power to entities closest to the money printer.

The US dollar's dominance is less about its role in oil transactions (petrodollar) and more about its deep integration into global banking and financial plumbing via the Eurodollar system. This structural entrenchment makes it incredibly difficult to displace.

Stablecoin adoption by U.S. entities merely shifts existing dollar assets from bank deposits or money market funds. True new demand for the U.S. dollar only materializes when foreign households or corporates convert their local currencies into dollar-backed stablecoins for the first time, creating a net FX conversion.

The U.S. economy's ability to consume more than it produces is not due to superior productivity but to the dollar's role as the world's reserve currency. This allows the U.S. to export paper currency and import real goods, a privilege that is now at risk as the world diversifies away from the dollar.

The US dollar reached its peak global dominance in the early 2000s. The world is now gradually shifting to a system where multiple currencies (like the euro and yuan) and neutral assets (like gold) share the role of reserve currency, marking a return to a more historically normal state.

The fall of the dollar as the world's reserve currency isn't an abstract economic event. It would have immediate, tangible consequences for citizens, including skyrocketing prices for imported goods like energy and medicine, a sharp drop in living standards, and an exodus of talent and capital to more stable regions.

As foreign nations sell off US debt, promoting stablecoins backed by US Treasuries creates a new, decentralized global market of buyers. This shrewdly helps the US manage its debt and extend the life of its reserve currency status for decades.
