Japan's latest efforts to curb yen depreciation are facing mounting challenges. Unlike previous administrations that prioritized exchange rate stability, Prime Minister Sanae Takaichi's cabinet has signaled tolerance—even welcome—for a weaker yen, rendering the Finance Ministry's verbal interventions ineffective and plunging Japan's "yen defense" into a policy quandary.

Market skepticism became evident this week. Despite Finance Minister Satsuki Katayama's warning about authorities' vigilance against "one-sided, sharp fluctuations" and acknowledgment of the yen's growing negative impact, the remarks failed to halt the currency's decline. USD/JPY briefly breached the key 155 psychological level this week, hovering near 154.50 on Friday, while the yen hit record lows against the euro.

Investors remain unmoved by official rhetoric as they observe Takaichi's cabinet core being dominated by "reflationists" advocating fiscal expansion and monetary easing. Reports indicate these new policy advisors openly tout the benefits of a weaker yen. Meanwhile, Takaichi and her finance minister have expressed dissatisfaction with potential Bank of Japan (BOJ) rate hikes, reinforcing expectations of delayed monetary tightening.

With rate hikes constrained by political will and FX intervention facing high barriers, Japanese policymakers appear to have limited tools left to counter yen depreciation. This sustains downward pressure on the currency, which may weaken further without effective policy brakes.

**Dovish Cabinet Undermines Intervention** Contradictory signals within the government are severely eroding its market communication effectiveness. Finance Minister Katayama's Wednesday verbal warning failed partly because it lacked escalation to more deterrent phrasing like "prepared to take decisive action," which markets interpreted as insufficient intervention resolve.

Concurrently, other cabinet members' remarks deepened skepticism. Economic Revitalization Minister Minoru Kiuchi last month cited yen weakness as growth-positive, adding Tuesday that its import cost push was fading—a stark contrast to previous governments' focus on imported inflation's household burden. Mizuho Securities chief FX strategist Masafumi Yamamoto noted:

"Prime Minister Takaichi's government hasn't escalated its warnings, signaling tolerance for yen weakness."

He predicts Japan may only intensify verbal warnings if USD/JPY breaches 155, with direct intervention considered beyond 160.

**Easing Stance Clouds Rate Hike Outlook** Takaichi, a staunch "Abenomics" adherent, has appointed low-rate advocates like economist Takuji Aida to key growth strategy roles. Advisors like Aida argue a weaker yen mitigates U.S. tariff impacts on manufacturers.

Despite over three years of above-target inflation and household discontent, the government's easing stance remains firm. While BOJ Governor Kazuo Ueda hinted at possible June rate hikes amid mounting price pressures, Takaichi and her finance minister quickly countered that Japan hasn't achieved sustainable inflation—directly influencing policy expectations. BNP Paribas chief Japan economist Ryutaro Kono stated:

"The Takaichi administration's reflation bias appears stronger than initially thought."

He has revised his 2025 BOJ hike forecast from three to two moves based on recent appointments.

**High Intervention Bar Weighs on Yen** With rate hikes constrained, FX intervention remains the last tool to stem yen declines—but its activation threshold is steep. Japan last intervened in July 2024 when USD/JPY hit a 38-year low of 161.96, coinciding with a BOJ hike to 0.25%.

However, Takaichi's government faces tougher intervention conditions now. U.S. Treasury Secretary Bassett has repeatedly suggested rate hikes as the optimal yen support, making Washington's approval unlikely. Domestically, skepticism persists—former BOJ official Toru Sasaki calls yen-buying intervention amid deeply negative real rates "foreign reserve waste," predicting no action unless USD/JPY exceeds 165. With limited policy options, sustained yen pressure appears inevitable.
