Will Japan 10Y JGB yield exceed 2.75% by September 30, 2026?
The Condition
BOJ raises policy rate to 1.00% or higher by end of July 2026
Our Ensemble Estimates
Given BOJ reaches 1.00%+: Will Japan 10Y JGB yield exceed 2.75% by September 30, 2026?
Given BOJ stays below 1.00%: Will Japan 10Y JGB yield exceed 2.75% by September 30, 2026?
Causal Effect
BOJ reaching 1.00%+ worth ~27pp increase in probability of JGB 10Y exceeding 2.75% — amplified pass-through ratio (1.74x) and fiscal-monetary tension from Takaichi expansion drive yield acceleration
Why This Matters
Tests whether aggressive BOJ normalization pushes JGB 10Y yields to levels not seen since the late 1990s. The analysis identifies a 1.74x pass-through ratio at the 10Y point -- financial markets are overshooting BOJ policy rate changes, amplified by QT and the Takaichi fiscal expansion creating a dual yield pressure. Current JGB 10Y is at 2.24%, already up 87bp in 12 months. With the 30Y JGB at 3.4% reflecting fiscal premium, the curve is steepening under fiscal-monetary tension. Two additional hikes to 1.00%+ with the amplified pass-through could push the 10Y toward 2.75%+, potentially forcing BOJ to choose between inflation control and bond market stability.
Resolution Criteria
Japan 10-year government bond yield (FRED series IRLTLT01JPM156N or MOF Japan daily reference rate) closes at or above 2.75% on any trading day on or before September 30, 2026
Source Analysis
JGB 10Y yields at multi-decade highs with 1.74x pass-through ratio amplified by QT and fiscal concerns; further hikes accelerate repricing
