The recent relief rally in South Korean bonds looks like it's hitting a wall. Strategists are warning that government measures to dampen volatility are losing steam, and the market is bracing for a sharp reversal. The 10-year yield, which dipped on intervention fears, is now expected to snap back to 4.6%—a level last seen in September and the highest since 2022. The three-year benchmark is tracking toward 4.1%, up from 3.98% on Thursday. This isn't a minor wiggle. It’s a potential retest of four-year highs.
But why the sudden shift? Inflation. The Middle East conflict has pushed oil prices higher, keeping inflation stubbornly above the Bank of Korea’s target. Meanwhile, the semiconductor and memory-chip boom is driving economic growth faster than expected. Rajeev De Mello, global macro portfolio manager at Gama Asset Management SA, put it bluntly: “I am becoming more cautious on Korean bonds... If the global bond selloff continues, it will become increasingly difficult for Korean yields to resist the upward pressure.”
The market is pricing in pain. Won swaps are betting on about a 70% chance that the BOK will raise rates by a cumulative 50 basis points in the next six months. The central bank has already hiked back-to-back to 3% to cool the economy. Park Junwoo, a fixed-income strategist at Hana Securities, called the current yield dip a trap. “I don’t think now is the time to buy, but it would be worth buying again if it goes back above 4%,” Park said, referring to the three-year yield. His firm is underweight on both Korean and US bonds.
The next trigger? The BOK’s policy meeting later this month. A dot plot released in August showed 10 of 21 policymakers favoring a 3.25% rate. Traders are watching for a hike after a hold on Oct. 22, with yields likely to peak around the November meeting. But the government has a counter-move: Finance Minister Lee Hyoung Il has hinted at further cuts to planned debt sales, citing a tax windfall from the chip industry.
So, is it a buying opportunity or a trap? Woo Hye-young, a fixed-income analyst at LS Securities Co., thinks the yield surge will invite more intervention. She’s willing to wait for the November dot plot to confirm the direction. “It won’t be too late to wait for the BOK’s dot plot in November to buy Korean bonds,” she said. “If the November dot plot shows something higher, I’d be more cautious.” For now, the bond market is in a holding pattern, but the bulls are getting nervous.
