The benchmark 10-year Japanese government bond (JGB) yield rose 2 basis points to 2.790% on Monday, marking the sixth consecutive session of gains.

The move pushes the rate closer to its highest level in 30 years, reflecting persistent investor anxiety over the Bank of Japan’s policy trajectory and the sheer volume of upcoming sovereign debt issuance.

Traders are increasingly focused on the fiscal implications of Japan’s budget plans, with concerns that aggressive government borrowing could outstrip demand.

The yield climb comes as global bond markets face headwinds from resurgent inflation fears and broader geopolitical tensions, including renewed hostilities in the Gulf region that have already pressured US Treasuries.

This repricing in Tokyo aligns with a wider trend of sovereign debt issuance surging globally.

As fiscal expansion and persistent inflation risks force major economies to tap markets more aggressively, investors are grappling with the dual pressures of higher supply and uncertain monetary policy paths.
