Trump Calls Yen Intervention a "Signal of Friendship"
0xBroomberg
The U.S. and Japan jointly intervened to buy yen for the first time in 15 years. Trump called it a 'friendship signal' — elevating the move from a technical FX operation to a political endorsement that raises the cost of walking away.
What happened?
Japan's Finance Minister Katayama Satsuki will formally announce on August 4 that Japan and the U.S. jointly bought yen last week to stop it from falling to a 40-year low.
This is the two countries' first joint yen intervention in 15 years, and the operation is "still ongoing."
Trump told reporters aboard Air Force One on August 2 that U.S. involvement was "a friendship signal" — the most direct political endorsement of this round of coordinated action.
How big is the intervention?
Bank of Japan data suggest Japan's intervention in New York on Thursday alone may have reached $58.97 billion.
A Reuters photograph showed U.S. Treasury Secretary Scott Bessent's handwritten to-do list at a cabinet meeting: "Buy yen $5B–$10B."
This means → Washington is not just offering verbal support — it is preparing to put real money in. That has not happened in 15 years.
How far had the yen fallen?
USD/JPY hit around 164 earlier in the week — the highest since 1986.
After the joint intervention, it closed Friday at roughly 157.60, a sharp pullback.
In plain terms = the yen had fallen so far that it was pushing up import prices, fueling inflation, eroding household purchasing power, and dragging down Prime Minister Takaichi Sanae's approval ratings — politically unsustainable.
What is the Bank of Japan doing on its own?
The BOJ held rates steady on Friday but sent its clearest early-rate-hike signal yet.
It had already raised the benchmark rate to a 31-year high of 1% in June, but the yen barely responded.
This reflects a hard reality: rate hikes alone were not enough — hence the need to bring the U.S. into a joint FX operation.
Why is the U.S. willing to step in?
Bessent had already said publicly that the yen appeared "significantly undervalued" and repeatedly urged Japan to raise rates.
South Korea also intervened to buy won on Thursday, signaling a broader regional dimension to this round of coordination.
This means → it is not just a favor to Japan — the U.S. is leading a collective recalibration of Asian currencies.
Can the intervention last?
Japan intervened unilaterally in April and May, but the effect was short-lived.
Trump's public framing elevates the intervention from a technical operation to a political signal — raising the political cost of an American withdrawal.
In plain terms = the president called it "friendship" on the record. Walking away now would mean contradicting himself. But whether the joint intervention holds depends on whether the BOJ actually follows through on rate hikes and whether the U.S. Treasury actually executes its yen purchases.
