Japanese yen jumps after joint US‑Japan market intervention

BOOCKVAR: “.. the only reason why the US Treasury and Scott Bessent are getting involved in defending the yen is because they don’t want US Treasuries to be a source of funds for the Japanese.” peterboockvar.substack.com/p/pretty-ple...

The U.S. dollar is TUMBLING after Trump’s Treasury dumped billions in U.S. reserves to buy Japanese yen. ​The market chaos happened just hours after Trump stood aboard Air Force One bragging that "the dollar is doing great," framing the sell-off as a "signal of friendship" to Japan right after

President Trump on why we are saving the Japanese Yen:

largest intervention to save the yen since the 1980s???

the more nerdy point is that both the Japanese and US side here are talking about countering "disorderly" yen movements. What disorderly yen movements? it's been incredibly orderly.

The US dollar weakened sharply against the Japanese yen after Trump & Japan's finance minister confirmed both sides had intervened in markets. The dollar had been trading above 163 yen, a 40 year high.The dollar then dropped about 1% to 156.34 yen. That's a big change for the exchange rate. #Blues

Okay i didn't expect that thread about consumers to pop off so much. Clearly i should do a series about this sometime. But this week is about the Japanese Yen.

Trump said the intervention would be “good for the world economy,” but some analysts suggest the Trump administration is concerned that Japan’s efforts to buy up yen, raising the value of their currency, could hit the US economy by making government borrowing more expensive, The Guardian reported.

Coming up on #KTLA: The Trump administration says it's spent billions of U.S. taxpayers' money propping up the Japanese yen because we're good guys. In reality, there's a more self-interested reason. I'll explain (in plain English)

"Trump Spends Taxpayer Dollars on Shoring Up Japanese Yen." (No headline ever.)

"Industry veterans told CNBC that one of Washington’s biggest concerns was avoiding a scenario where Japan would need to dump large quantities of Treasurys to finance unilateral intervention, given how the north Asian nation is the largest foreign holder of U.S. government debt."

The United States and Japan coordinated to intervene in the currency markets to stabilize the weakening yen last week, a rare move that last occurred more than a decade ago www.nytimes.com/2026/08/02/b...

In saving the Yen, the US was trying to save itself. "The yen’s slide to a 40-year low indirectly threatened to bump up U.S. interest rates and risked throwing a wrench in plans to pull billions of dollars of Japanese investment into the U.S." www.wsj.com/finance/curr...

“This prompted one of the most dramatic interventions in global currency markets in decades — a joint Japanese-US effort to bolster the yen, accompanied by a joint warning that the two nations wouldn’t hesitate to move again to defend its value if required.” — www.bloomberg.com/news/article...

The US dollar is extremely weak under Trump, so what does he do? He props up Japan's yen at the dollar's expense. finance.yahoo.com/markets/curr...
