Bankers warn Bessent’s yen push risks undermining BOJ credibility

Treasury Secretary Scott Bessent's declaration that he is "the house" in the currency markets has drawn pushback from traders and warnings from bankers that his public pressure campaign risks undermining the Bank of Japan's credibility as an independent central bank.

Speaking at a Southern Methodist University event in Texas on Tuesday, Bessent challenged traders to bet against his effort to strengthen the Japanese yen. "I am the house now, so when we intervene with the Japanese yen, I have pretty good insight into what the Japanese, what the Bank of Japan is going to do, what Japanese policymakers are going to do," Bessent said, according to Bloomberg.Bloomberg+1

Markets Push Back

Despite weeks of verbal intervention and a coordinated U.S.-Japan effort to prop up the yen, markets have not fully cooperated. The USD/JPY pair bounced back above 154 on Wednesday and Thursday after touching a seven-month low near 153 earlier in the week. The rebound, driven in part by short-covering in oversold conditions, underscored the limits of jawboning alone.TRADING ECONOMICS+1

The yen has strengthened roughly 6% from its late-July peak near 164 — close to its weakest level in 40 years — but remains far from the 150 level Bessent himself has suggested as a target. Speculators still hold a large net short position on the yen, though that positioning has been unwinding in recent weeks.xtb

Credibility Concerns

The Financial Times reported Friday that bankers warned Bessent's claims of "asymmetric information" about BoJ plans risk eroding market perceptions of the Japanese central bank's independence. Bloomberg reported that his public pressure campaign is raising expectations for a monetary tightening cycle "unseen in more than a generation," creating the danger of market disruption should the BoJ fail to deliver.Financial Times+1

The BoJ is scheduled to meet on September 17–18, with markets pricing in a high probability of a 25-basis-point rate hike. Bessent met with BoJ Governor Kazuo Ueda at the G20 finance leaders' gathering in Asheville, North Carolina, in late August, urging "decisive" steps to combat yen weakness.Reuters+1

A Former Trader's Gambit

Bessent's background adds a layer of irony. As a hedge fund manager, he helped George Soros profit from breaking the Bank of England's currency peg in 1992. Now sitting on the other side of the table, he is daring traders to challenge a central bank's resolve — while some in Tokyo worry his public commentary may be the very thing that weakens it.Yahoo!
