Why I Believe the Yen Could Become the Core Battle in US-Japan Trade Talks

At first glance, Japan seemed to have sidestepped US pressure over the yen during the recent finance talks between Japanese Finance Minister Katsunobu Kato and US Treasury Secretary Scott Bessent. Kato insisted there was no discussion of exchange-rate targets, and no accusation from the US side regarding currency manipulation. However, the details tell a different story.

Kato also mentioned that Japan and the US would continue “close and constructive dialogue” on exchange rates within the framework of broader trade negotiations. This language is crucial. It suggests that while currency was not the headline issue in this meeting, it is quietly becoming embedded into the upcoming US-Japan trade talks.

In my view, if the yen does become a central issue, several consequences are likely:

First, the US is highly likely to push for a stronger yen. President Donald Trump has long believed that Japan (like China) has intentionally kept its currency weak to itsboost exports at the expense of American manufacturers. Now that Trump is refocusing on reducing the US trade deficit, the yen’s value could easily become a political target again. A stronger yen would, in theory, make US products more competitive against Japanese goods.

Second, Japan would find itself in a tough spot. A stronger yen would directly hurt Japan’s major exporters — from automakers to tech companies — by squeezing their overseas profits. This would threaten Japan’s already fragile economic recovery, especially given the additional drag from Trump’s new tariffs.

Third, the Bank of Japan (BOJ) could face external pressure on its monetary policy. Although the BOJ raised rates to 0.5% in January, its pace of tightening remains extremely slow. US negotiators might argue that Japan’s ultra-loose monetary stance indirectly weakens the yen, effectively framing BOJ policy as a trade issue rather than a purely domestic matter.

In fact, Finance Minister Kato hinted at this when he said he had briefed Bessent on Japan’s “wage developments” and “price trends” — both of which are key inputs into the BOJ’s rate decisions. Analysts believe that a continued rise in wages and inflation would normally give the BOJ the green light to hike rates further, supporting the yen. But Trump’s tariffs and the resulting uncertainty could delay these plans, complicating Japan’s balancing act.

From my perspective, this situation feels like a slow-motion setup: If Japan resists US demands on trade, the yen could quickly move to center stage as leverage. And once the exchange rate becomes the battleground, Japan will have much less room to maneuver without risking either its exports or its fragile domestic recovery.

Ultimately, the story here is bigger than just a finance meeting. It’s about how economic policy, monetary decisions, and geopolitical strategy are becoming increasingly entangled.
