Yen Intervention: A Band-Aid Fix or a Long-Term Solution?

The US Treasury Secretary Scott Bessent has characterized the country's support for Friday's yen intervention as a sign that President Donald Trump's government 'delivers for America's trusted partners'. However, a more plausible reading is that the administration is growing uneasy with its own climbing borrowing costs and wants to avoid forced selling of Treasury securities by their biggest overseas holder.

The US joined Japan in bolstering the yen last week, marking the first American yen intervention in 15 years. The Japanese currency has been trading near its weakest in four decades due to low bond yields, concerns about fiscal and monetary policy credibility, and a terms-of-trade shock delivered by the US-Iran war.

Some argue that Japan needs to raise interest rates to compete with rising rates around the world and shore up its currency. However, policymakers have been slow-playing normalization, and markets have grown suspicious of their independence from Prime Minister Sanae Takaichi's government.
