BOJ board member Naoki Tamura urged a “decisive” interest rate increase as underlying Japanese inflation accelerates toward the 2% target—despite headwinds from looming U.S. trade tariffs.
Rising Core Inflation Makes Rate Hikes More Likely
Japanese core CPI jumped to 2.1% year-on-year in May, its highest level in over two years. Even excluding fresh food and energy, underlying consumer inflation is proving stickier than expected.
-
Wage Growth Support: Firms have begun boosting base pay, underpinning household spending.
-
Tariff Pressures: A 10% universal U.S. tariff and a 25% levy on cars threaten to push import prices higher.
-
Domestic Demand: Retail sales and service-sector activity remain resilient, adding to price pressures.

Tamura vs. Ueda: Diverging Views on Timing
Tamura’s hawkish stance contrasts with Governor Kazuo Ueda’s more cautious approach:
| BOJ Member | Viewpoint |
| Naoki Tamura | “Decisive” hikes needed soon; inflation unlikely to fall back. |
| Kazuo Ueda | Prefers measured moves; uncertainty warrants patience. |
While Tamura softened his tone later—acknowledging no “preset idea” on timing—his comments shift the policy debate decisively hawkish.
USD/JPY Reaction and Trade Talks
The yen strengthened to ¥145 per dollar on Tamura’s remarks, up from ¥148 last week. With U.S.–Japan trade talks stalling, currency markets are pricing in a higher BOJ terminal rate.

What Investors Should Do Now
-
Reassess Japanese Bonds: Rising rate expectations may spur widening Japan Govt. bond yields—trim duration if break-even inflation stays elevated.
-
Currency Hedging: Consider hedging yen exposures or rotating into exporters benefiting from a stronger yen.
-
Tariff Impact Watch: U.S. auto and parts stocks may underperform; track tariff negotiations for sudden reprieves or escalations.
Bottom Line:
With core CPI at two-year highs and trade uncertainties looming, Tamura’s hawkish pivot makes a BoJ rate hike more than theoretical.
