US and Japan Currency Intervention Hints at Eroding Dollar Dominance

A recent joint currency intervention by the U.S. and Japan reveals that the dollar's reserve status is not as dominant as it once was.

The U.S. Treasury Department took a new approach in its intervention, buying yen with euros rather than dollars. This move was seen as an attempt to preserve dollar strength while still supporting the Japanese currency.

According to UC Berkeley economics professor Barry Eichengreen, this unusual move by the U.S. reveals a deeper concern: the sagging demand for U.S. Treasuries is a growing problem for U.S. policymakers.

The demand for U.S. Treasuries has been dropping, leading to lower prices and higher yields. This increases the federal government's borrowing costs, which are already over $1 trillion per year in interest expense.

Eichengreen notes that selling euros rather than dollars was likely partly a function of what the Treasury had on hand in its currency stabilization fund. However, he believes there is more to the operation than just that.

The U.S. intervention also highlights the growing trend of reserve diversification among central banks. With the dollar's status as a reserve currency not as attractive as it once was, other countries are looking for alternative assets.
