Korean corporate bond yields reached their highest levels in 2 years and 8 months on the 24th, with AA- rated 3-year bonds hitting 4.653% — the peak since November 14, 2023. The surge followed the Bank of Korea's rate increase from 2.50% to 2.75% on the 16th and escalating Middle East geopolitical risks that elevated broader bond market rates. Credit concerns intensified after JR Global REIT's April default on 40 billion won in debt and Central Group's rehabilitation filings last month, widening the credit spread between 3-year government bonds and AA- corporate bonds from 52.4 basis points on January 2 to 69.4 basis points on the 24th. Despite elevated absolute yields attracting capital to investment-grade issuers, demand polarization deepened as BBB-grade bonds faced investor aversion.
AA- Corporate Bond Yields Hit 4.653% on the 24th
AA- rated 3-year corporate bond yields climbed to 4.653% on the 24th, marking the highest level since November 14, 2023, when yields reached 4.704%, according to BondWeb data reported on the 27th. The rate recorded 4.576% on the 27th after three consecutive trading days of annual highs. BBB- rated 3-year corporate bonds hit 10.450% on the 24th, the highest since February 2024, and stood at 10.373% on the 27th. The credit spread between 3-year government bonds and AA- corporate bonds widened from 52.4 basis points on January 2 to 69.4 basis points on the 24th, expanding further to 71.2 basis points as of the afternoon on the 27th.
Bank of Korea Rate Hike and Middle East Tensions Drive Yield Surge
The Bank of Korea raised its base rate from 2.50% to 2.75% on the 16th, ending eight consecutive holds. Market participants interpret the move as the start of a rate hike cycle, with some securities firms projecting the base rate could reach 3.50% by year-end. If realized, 3-year government bond yields could exceed 4% by late 2026, according to industry forecasts. Armed conflict between the United States and Iran increased international oil price volatility, raising concerns that inflation pressures could prolong central bank tightening beyond current expectations. Risk-aversion sentiment tied to Middle East instability amplified volatility across the domestic bond market.
JR Global REIT and Central Group Credit Events Pressure Lower-Grade Bonds
JR Global REIT failed to repay 40 billion won in bond principal and interest in April and filed for rehabilitation as the value of its core asset, Belgium's Finance Tower, declined and a cash trap materialized. Last month, JTBC failed to repay securitization borrowings, followed by rehabilitation filings from Central Holdings, Contents Joong-Ang, and Megabox Joong-Ang — major Central Group affiliates. The credit issues at Central Group, a significant issuer in the BBB-grade corporate bond and retail bond markets, triggered aversion to lower-grade bonds among individual investors and high-yield funds. Hanjin (BBB+) received 44 billion won in orders for a 40 billion won bond issuance on the 14th but left 1 billion won unsold in the 1-year maturity, illustrating weakened BBB-grade investment appetite despite total orders exceeding the target. Analysts noted that Hanjin held a 'positive' rating outlook within the BBB+ category, indicating market caution extended beyond individual issuers to lower-grade bonds broadly.
SK Ecoplant and KCC Attract Multi-Billion Won Orders in Demand Forecasts
SK Ecoplant (A-) garnered 987 billion won in orders for a 100 billion won bond issuance on the 22nd, approximately 10 times the target amount. All maturities exceeded their respective募集 targets, and issuance rates settled below individual fair value rates. KCC (AA-) secured 1.385 trillion won in orders for a 200 billion won bond issuance on the 23rd. Choi Sung-jong, an NH Investment & Securities researcher, stated that the credit market is experiencing carry demand inflows for high-grade bonds offering stable interest income, with issuers conducting demand forecasts securing funds reliably amid limited corporate bond supply. Choi added that while caution persists regarding the timing and frequency of base rate hikes, elevated rate attractiveness and government-led structural adjustments in unfavorable sectors are preventing additional credit events, making selective carry investments in top-tier and high-quality corporate bonds effective.
