We introduce our BoJ PSI, an index tracking each member's stance on Economy, Inflation and Policy Rate. We attribute anonymous remarks in meeting minutes to individual members to produce PSI.
A proof of concept is Nakagawa Junko's April rate hike dissent, which surprised the market. Our PSI record shows her inflation assessment rising from November 2025 through March 2026.
With a June hike well priced in, the question is the timing of the next hike. Our PSI should provide a transparent way to monitor swing votes, Koeda and Masu.
