Nobody appreciates back-seat driving, yet Bank of Japan Governor Kazuo Ueda currently faces two such passengers demanding he accelerate at different speeds. On Friday, Ueda raised interest rates for the second time in three months, a move that aligned with the wishes of US Treasury Secretary Scott Bessent, who had supported the yen and urged faster monetary tightening from Tokyo. Meanwhile, Prime Minister Takako高市’s focus rests on accelerating economic growth; her two appointees to the central bank’s policy board were the only dissenters against Friday’s hike. This foreshadows potential friction next year when she gets the chance to replace its two most hawkish members.
As global bond market turbulence pushes inflation and borrowing costs higher nearly everywhere, satisfying both constituencies becomes increasingly difficult. It remains unclear what interest-rate level would satisfy Bessent, whose priority is avoiding any Japanese instability spilling into US treasuries. How rate levels align with the prime minister’s view of domestic demand is equally uncertain—while inflation may be tracking above target, consumer spending and broader growth have lagged behind.
According to Atsushi Takeuchi, a former head of the Bank of Japan’s foreign exchange division, “Ueda’s balancing act is extremely tricky. He is squeezed between the pressures of 高市 and Bessent. Compared with the US and Europe, Japan’s inflationary pressures are weakest. In fact, if the BOJ tries to hike in tandem with other central banks, it would lose out.” Rapid tightening risks pushing Japan back into the prolonged stagnation it has only recently escaped, and it raises thorny questions about central bank independence if Tokyo appears to follow Washington’s playbook. Moving too cautiously, however, could squander the gains from currency intervention—an operation backed by Bessent with American funds and prestige, which succeeded in pulling the yen off its 40-year low. With impending board changes, the window for policy normalization may be closing.
Ueda described monetary policy as entering a “new phase” during Friday’s press conference, refusing to rule out another hike in October or, at some point, a larger-than-usual move. Despite his hawkish tone, markets remained skeptical; the yen slipped 1.3% against the dollar by 7 p.m. in Tokyo. While Ueda insisted the BOJ would not set rates to control currency markets, many investors view exchange-rate movements as a key driver of decisions. Shoki Omori, chief fixed-income strategist at Deutsche Bank in Japan, said the job had become “as difficult as it gets,” adding that “no single approach can satisfy investors, Washington, and the Japanese government simultaneously.”
For now, enough common ground exists to maintain unity. Local media described Bessent’s remarks as unusually direct pressure on the BOJ, with sources noting a quiet resistance within the central bank in the days before Friday’s decision. Officials privately held that their decisions rest on inflation, economic, and financial conditions—not statements from foreign or domestic politicians.
Yet Ueda may welcome Bessent’s support for further hikes as a counterweight to 高市, who has shown little resistance to this dynamic—perhaps the price paid for US help in defending the yen. It may also keep Washington satisfied ahead of the prime minister’s potential meeting with President Donald Trump in New York next week. Still, 高市 has adjusted Japan’s main debt metrics to free up room for increased spending. Faster growth plus some inflation serves that goal, whereas rising rates would elevate debt-servicing costs—projected to grow by about 30% by 2029.
The dissenting votes from her two appointees on Friday signal a higher hurdle for future hikes. Yet around 80% of economists polled believe Tokyo’s opposition to tightening may have become harder following Bessent-backed intervention. Tominaga Norinori, a former BOJ board member and now executive economist at Nomura Research Institute, said Bessent’s public advocacy for higher rates “freed the BOJ from domestic political pressure, which is significant.” He added that since the 高市 government took office last year, the central bank has faced noticeable political interference, having previously delayed hikes under strong government opposition—but this time, thanks to the US, they moved forward.
Observers are split on timing for the next increase, with December the most popular pick, followed by January. Beyond 2027, the outlook grows murkier. Hawkish board members Hajime Takata and Naoki Tamura both depart in July next year; if 高市’s replacements lean dovish like Friday’s dissenters, the balance on the nine-member policy board could shift dramatically.
