South Korea 10-Year Bond Yield Drops to 6-Week Low Near 4.25% as Government Cuts Debt Sales
South Korea's 10-year government bond yield dropped to roughly 4.25% in mid-October, reaching its lowest level in six weeks. The retreat in yields followed direct government actions designed to soothe volatility across fixed-income markets, including warnings of potential currency intervention and a reduction in scheduled monthly debt issuance.
To stabilize sovereign borrowing costs, authorities trimmed planned government debt sales for October by 5 trillion won ($3.74 billion). Even with these relief measures, underlying upward pressure on borrowing costs persists. Elevated global crude oil prices continue to fuel inflation concerns, while a broader global bond selloff and robust domestic economic growth boosted by a booming semiconductor sector add further price pressures.
Investors are now monitoring the Bank of Korea ahead of its October 22 rate-setting meeting, where central bankers may pause rate moves before considering further monetary tightening in November. Following consecutive rate hikes that lifted the benchmark policy rate to 3%, won swap markets are currently pricing in roughly a 70% probability of 50 basis points in cumulative rate increases over the next six months.
