Seoul's bond market tracked foreign investor trends on August 6 as domestic prop dealers remained on the sidelines amid a foreign-led rally. The rapid strengthening pushed rates beyond dealers' expected ranges, creating a wait-and-see atmosphere, though domestic banks and securities firms benefited from rising bond valuations. A macro hedge fund representative noted that amid significant volatility in dollar-won exchange rates and KOSPI without clear anchors, approaching interest rate levels with confidence carries risk, suggesting sideways trading at somewhat lower rate levels despite limited room for further strengthening. The market did not reject the Bank of Korea's hawkish stance—IRS rates within one year showed relatively smaller declines, supporting the narrative that faster tightening pace could reduce total tightening magnitude.
New Zealand and Australia Mid-Term Rates Drop Alongside Seoul Market Strength
New Zealand and Australia mid-term rates fell approximately 8bp and 4bp respectively on the previous day, indicating Seoul's bond strength was not uniquely pronounced. Market participants attributed the moves to trading following Hormuz Strait opening expectations and international oil price declines across Asian bond markets. Macro hedge funds and trading institutions that had taken short positions in IRS and government bond futures markets began increasing duration from relatively safer back-end maturities. Curve flattening has been commonly observed in recent global bond markets.
BIS Report Compares 2026 Energy Shock Response to 2022 Patterns
The Bank for International Settlements released a report on August 5 titled "Energy shocks and inflation: challenges for monetary policy" analyzing the current energy shock following the Iran war. BIS assessed that while this energy shock represents the most significant level since the 1990s, financial market reactions differed from 2022. Five months after the Iran war outbreak, real interest rate changes in the US and Japan were smaller than in 2022, while the euro area showed larger real rate changes than in 2022. The report attributed this to the region's high dependence on oil and natural gas, making it vulnerable to shocks.
Asian countries including South Korea maintain high dependence on the Hormuz Strait. According to Nomura Securities, Korea's Middle East-sourced energy imports account for 54.2% of total energy imports, higher than Thailand's 52.4% and Japan's 50.3%. Negotiation expectations regarding Hormuz Strait uncertainty, which had acted as a weakening factor, may have provided strengthening momentum. Some rate hike expectations reflected in mid-term instruments originated from uncertainty rather than monetary authority guidance, and the reduction of this uncertainty component may have contributed to the rally.
Bank of England Research Identifies Risk Premium in Short-Term Curves
The Bank of England previously presented research results on the significant gap between monetary authority policy stance and policy expectations reflected in bond market rates. Report authors decomposed the OIS curve path into "policy rate expectation path" and "risk premium" components. The analysis found that while six-month premiums typically remain near zero, they spiked significantly into positive territory only during the 2022-2023 high inflation period and immediately after the Iran war in February 2026.
The report concluded that the upward-sloping curve observed in short-term maturities immediately after the Iran war reflected compensation for short-term policy and economic uncertainty rather than policy rate scenarios. Considering this framework, market observers noted interest in estimating how much term premium embedded in domestic mid-term rates could potentially compress, even while acknowledging steep nominal economic growth and resulting demand-side inflation pressures. Market participants will monitor whether foreign investors show speed adjustment moves ahead of the US employment report release.
BIS noted in the report that while differences exist across countries, overall conditions differ from 2022 due to factors including labor market weakening from AI adoption and less accommodative monetary and fiscal policy stances. This assessment can be viewed as supporting logic for recent mid-term rate strength.
