The policy landscape has shifted toward a more aggressive hawkish tilt over the last 30 days. While the BOJ held rates at 0.75% in April, the decision was marked by a significant split, including three dissents. The primary catalyst is a "Middle East shock" (Iran war worries) that has sharply increased the FY2026 inflation outlook and spiked wholesale inflation. New board member Kazuyuki Masu has emerged as a vocal hawk, warning that the current energy shock could be more severe than the 1973 crisis and calling for an immediate rate hike. Market expectations and internal board dynamics now strongly point toward a potential hike to 1.0% in June, supported by rising real wages in March and surging Tokyo CPI.

1. Inflation Assessment (CPI, Core, Wages)
Inflation is the primary driver of current hawkishness. Tokyo CPI surged to 1.5% in April, and core inflation held at 1.8% despite energy volatility. Crucially, real wages rose in March, providing the "virtuous cycle" evidence the BOJ seeks. However, the "Middle East shock" is creating a cost-push surge in wholesale inflation.
2. Growth Outlook
Growth remains a secondary concern compared to inflation risks, though member Masu noted that a hike is appropriate "unless the economy weakens."
3. Yen / FX Considerations
Higher yields are currently supporting the prospect of a hike; MUFG notes that higher yields are providing necessary support for the Yen.
4. Financial Conditions & JGB Market
Deputy Governor Himino continues to emphasize the global monetary system's stability, though the market is now pricing in a June move to 1.0%.
5. Balance Sheet (JGB purchase taper)
No specific updates provided in the last 30 days regarding the pace of the taper.
6. Forward Guidance Evolution
The BOJ has moved from "cautionary" to "signaling." The sharp upward revision of inflation forecasts in April serves as a proxy for forward guidance, signaling that the path to 1.0% is accelerating.
HAWKISH (favor faster normalization / rate hikes)
├─ Hajime Takata (Serial dissenter; pushed for 1% in Jan/Mar)
├─ Naoki Tamura (Consistent hawk)
└─ Kazuyuki Masu (Active; warns of 1973-style shock; wants immediate hike)
NEUTRAL/DATA-DEPENDENT
├─ Kazuo Ueda (Managing risks; cautious but open to hikes)
├─ Ryozo Himino (Focus on stability/holistic approach)
├─ Junko Koeda (Consensus-follower)
└─ Junko Nakagawa (Lame duck; term ends Jun 29)
DOVISH (favor maintaining accommodation / slower hikes)
├─ Shinichi Uchida (Pragmatic; emphasizes stability)
└─ Toichiro Asada (Reflationist; joined Apr 1)
Key Shifts Identified:
- Masu's Activation: Kazuyuki Masu has moved from "Neutral/Hawkish" to a primary driver of the hawkish narrative, explicitly calling for an immediate hike.
- Board Fragmentation: The April hold was not a consensus; the 6-3 split indicates the "Neutral" block is leaning Hawkish.

The April MPM saw a significant breakdown in consensus. While the policy rate was held at 0.75%, three members dissented, favoring a rate hike. This follows Hajime Takata's previous lone dissents in January and March 2026, suggesting the hawkish minority has expanded to a substantial bloc (33% of the board).
