AI Summary. Japan's two traditional options for supporting a weak yen — much higher Japanese interest rates or large sales of dollars and US Treasuries — would both pressure US yields, as Japan holds about $1tn of Treasuries. US willingness to back Japan via its exchange stabilization fund and the Federal Reserve's international repo facility suggests officials see that risk.

To shield Treasuries from selloffs and higher yields, the US prefers its own yen support tools: ESF yen purchases as a signal and the Fed’s rarely used FIMA facility, lending Japan dollars against Treasuries to forestall direct Japanese Treasury sales.

Does supporting the yen serve US Treasury market interests?

Core argument: Japan holds $1tn of US Treasuries, the world's largest such holdings and just under 4% of the total outstanding, so Japanese dollar sales to prop up the yen would add a large seller to the Treasury market.

Japan has two traditional routes to push up the battered yen. One is a massive rise in Japanese interest rates, and the other is massive sales of dollars — i.e., of US Treasuries. Neither would be good news for the US. Japanese yields are already seriously elevated by historical standards — 2.8% on the 10-year and 4% on the 30-year. The US is just not in a position to lose a big buyer of Treasuries when its own 10-year yield is tickling 4.7% and the 30-year is well over 5. And it certainly can’t tolerate a big seller of Treasuries, in the form of Japanese authorities selling dollars, hoping to prop up the yen. (Japan’s Treasury holdings already lead the world, at $1tn, or just below 4% of the total outstanding.) Much better to stand behind Japan and hope to scare off the yen sellers. Recent use has been made of the Exchange Rate Stabilization Fund [ESF] to signal that intent. Bessent has also said he will encourage the Fed to bump up Fima, the Fed’s international repo facility, in the coming months. This tool has rarely been wheeled out since it was established during the 2020 Covid shock. Its current $60bn per counterparty, per day limit has been reached just once. The fact that US authorities approved the use of this facility suggests the US side sees potential risk that fx intervention could push up US Treasury yields.

Takeaways by Macro Roundup® AI

  1. Japan holds $1tn of US Treasuries, the world's largest such holdings and just under 4% of the total outstanding, so Japanese dollar sales to prop up the yen would add a large seller to the Treasury market.
  2. Japan's two traditional routes to lift the yen — a massive rise in Japanese interest rates or massive sales of dollars — are both unwelcome for the US, whose 10-year yield is near 4.7% and 30-year above 5%.
  3. US authorities have used the Exchange Rate Stabilization Fund to signal support for the yen, and Bessent said he will encourage the Fed to raise its Fima international repo facility, whose $60bn per counterparty per day limit has been reached once.
