According to CoinMeta, affected by high energy prices and weak demand from life insurance companies, the yield on 30-year Korean government bonds rose to 4.67% on Wednesday, reaching the highest level for such bonds since 2012. The situation in the Middle East has driven up oil prices, and South Korea, as an energy-import-dependent economy, has been significantly impacted. A senior official from the South Korean Central Bank recently stated that the semiconductor industry is driving economic growth and contributing to potential inflation, necessitating interest rate hikes by the central bank, which has reduced market demand for ultra-long-term government bonds. South Korean life insurance companies have also decreased their purchases of ultra-long-term bonds due to adjustments in regulatory rules that have lowered the urgency to extend the duration of their assets.
