Mitsubishi UFJ Morgan Stanley Research Hub

Research from Mitsubishi UFJ Morgan Stanley underscores a period of significant volatility and structural anxiety within the Japanese Government Bond (JGB) market, characterized by a persistent bear steepening trend that recently pushed 10-year yields to 2.720%. Analysts attribute these movements primarily to mounting inflation uncertainty, driven by high oil prices and yen depreciation, rather than underlying economic optimism. While the market has largely priced in a preemptive Bank of Japan rate hike for June 2026, concerns remain that the BoJ’s current policy trajectory lacks the necessary hawkishness to stabilize the yield curve effectively. Divergent market signals, such as the counter-intuitive narrowing of ASW spreads and a surging 10-year break-even inflation rate, suggest a potential risk of disorderly yield increases decoupled from core fundamentals. Looking ahead, participants are closely monitoring upcoming 1Q26 GDP and Core CPI data as benchmarks for the BoJ's next policy maneuvers, with projections pointing toward interest rates potentially reaching 1.50% by mid-2027.
