日本债券在事件后持续抬头，10 年期殖利率已接近 1997 年以来高位，日本亦传出为稳定汇市而施作干预，规模高达 ¥10 兆（日圆，约 US$64 billion）。Davos 会谈后，Bessent 对日圆发出的 so-called rate check 一度吓退投机资金、暂缓直接干预需求；但美方仍警戒持续依赖售债资金进场，可能推高美国公债殖利率。若日本在 Sanae Takaichi 领导下推进更扩张性的财政路径，例如消费税减免，而未充分回应通膨压力，Bessent 可能再度提高施压。
政策问题不只在汇率层面。BOJ 自 2023 年 4 月已由负利率转向 0.75% 正利率，但仍偏低，Bessent 仍主张加快升息并要求「policy space」。市场亦关注资本重新配置风险：日本利率上升可能放缓国内资金外流、提升资金回流本土，比重转移会影响全球流动性与Treasury融资条件。这与他先前的日本操作逻辑一致——他参与 Soros 团队时曾押注日圆、Key Square Capital 曾在 BOJ 政策转折中录得 30% 收益——显示其 2026 年东京至首尔行程兼具金融外交与战略讯号层面。
In January 2026, after a selloff in Japanese bonds spilled into U.S. Treasuries, Scott Bessent’s meeting with Finance Minister Satsuki Katayama in Davos was unusually hard-edged. People familiar with it said he spoke forcefully in private, while his public comments said he had coordinated with Japanese counterparts and expected volatility to ease. The trip was publicly routine, but it was his 54th visit to Japan since 1990, signaling a long-term pattern of shaping Japan’s policy mix through U.S. macro pressure, while Treasury risk rises as U.S. debt increases.
Japanese bonds have continued rising since then, with the 10-year yield moving toward levels not seen since 1997, while Tokyo is reported to have spent up to ¥10 trillion (about US$64 billion) in suspected FX defense. After Davos, Bessent’s so-called rate check for the yen temporarily scared away speculators and reduced the immediate need for direct intervention, but U.S. authorities remain alert that repeated intervention funded through Treasuries sales could still push U.S. yields higher. If under Sanae Takaichi the government pursues broader fiscal expansion, including possible consumption tax cuts, while insufficiently addressing inflation risk, Bessent is likely to raise pressure again.
The policy frame is broader than exchange-rate optics. BOJ has moved from negative rates to +0.75% since April 2023, yet still below most peers, and Bessent still argues for faster tightening and more aggressive moves. Markets are watching for possible capital reallocation: rising Japanese rates could slow flows into overseas assets, potentially shifting funds back onshore and changing global liquidity plus Treasury financing conditions. This logic echoes Bessent’s own Japan playbook—his Soros-era yen bets and Key Square Capital’s 30% gain during BOJ transition—which suggests the 2026 Tokyo-to-Seoul tour is both financial diplomacy and strategic signaling.
