Japanese Finance Minister Satsuki Katayama announced that US President Donald Trump raised concerns about the weak yen during his summit with Japanese Prime Minister Sanae Takaichi. Katayama, after confirming with the prime minister's office, stated that Takaichi responded by agreeing that, as a general principle, an undervalued yen is a problem. The prime minister expressed general concern about yen weakness, and Tokyo committed to close coordination with Washington on currency matters.
The news led to an immediate, though modest, reaction in the currency markets, with USD/JPY easing from around 158.70 to near 158.40. This development adds significant political weight to the pressure on the yen, as it suggests a shared concern at the highest levels of both the US and Japanese governments regarding the currency's weakness. This shift in sentiment changes the backdrop for currency traders, particularly concerning the risk of Japanese intervention.
While Katayama declined to comment on specific exchange-rate levels or the possibility of rate checks (calls to dealers that often precede intervention), the comments are significant because they lower the political barrier to potential joint action. The US Treasury had already purchased yen earlier this year as part of efforts to manage rising borrowing costs, and a US President's vocal unease about the yen's weakness makes further joint action more plausible. The Bank of Japan also recently raised its policy rate to 1.25%, with Goldman Sachs cutting its USD/JPY forecasts due to anticipated faster BOJ tightening and intervention threats.
Despite these developments, the market's reaction remained modest, largely due to the continued wide interest rate differential favoring the dollar, with US 10-year yields above 5.2%. Traders are still awaiting concrete action rather than just words. The key question now is whether the expressed concerns from Washington and Tokyo will translate into intervention if USD/JPY approaches 160 again. Previous interventions, including a joint US-Japan effort where the US bought Japanese yen as it dropped to a 40-year low, have shown varying degrees of temporary success, with some analysts noting that such actions often only buy time against structural factors driving yen weakness.
