JGB yields

Updated

What it is

This indicator tracks yields on Japanese government bonds across maturities — 2-year, 10-year, and longer-dated (20/30/40-year) — as the primary gauge of Japan's domestic interest-rate and monetary-policy cycle. Rising JGB yields reflect both Bank of Japan policy tightening and investor demands for term premium amid Japan's high public debt load. AA uses this as a core Japan-rates input feeding related indicators on capital repatriation and yen volatility.

Why it matters lately

JGB yields rose to multi-decade highs through 2026 as the Bank of Japan tightened policy, with the 10-year JGB yield hitting 2.93% on August 17, 2026 (a roughly 30-year high, highest since 1996), then 2.97% on September 1 and 3.06% by September 24, 2026. The 2-year yield rose to about 1.77%, its highest since April 1995, and the 5-year yield hit a record 2.235%; the Bank of Japan raised its policy rate by 25 basis points to 1.25% — the highest since 1995 — on September 18, 2026, in a 7-2 board vote.
