DBS forecasts the Bank of Korea will lift its base rate by 25bps to 3.00% at the August meeting, alongside upgrades to its GDP and CPI projections. The bank’s 2026 GDP growth forecast is seen rising to around 3.5% from 2.6%, following first-half growth of 3.8% year on year. Inflation assumptions could also be raised, with the 2027 CPI forecast moving towards 3.0% from 2.3%.
Price pressures remain mixed. Headline CPI eased to 2.8% year on year in July from 3.2% in June, but core CPI edged up to 2.6% from 2.5%, while housing price growth increased to 2.7% from 2.6%. However, a hawkish hold is also possible given tighter financial conditions, linked to KRW appreciation and higher KOSPI volatility, with policy left unchanged in August while keeping the option of an October hike.
Implications for Derivatives, Currency, and Bond Markets
With the Bank of Korea’s upcoming interest rate decision, we advise derivative traders to prepare for a highly anticipated 25-basis-point hike to 3.00%. Strong first-half economic growth of 3.8% and rising core inflation to 2.6% suggest that the central bank has plenty of room to tighten. To hedge against this hawkish shift, we recommend shorting three-year South Korean Treasury Bond (KTB) futures, as yields are primed to push higher.
The Korean Won has shown significant strength recently, driving the USD/KRW currency pair down toward the 1,310 level. We suggest traders buy short-term KRW call options or sell USD/KRW futures to capitalize on this ongoing currency appreciation. Even if the central bank opts for a hawkish hold this month, the strong signaling of a future rate hike will keep the Won highly supported.
KOSPI Volatility and Yield Curve Strategies
Equity markets are also showing increased volatility, with the benchmark KOSPI index reacting nervously to tighter financial conditions. We recommend buying defensive put options on KOSPI 200 futures to protect portfolios against a near-term downward correction. Historically, a combination of rising interest rates and cooling stock market liquidity pressure local equities, especially when housing prices continue to climb.
If the central bank officially upgrades its GDP growth forecast toward 3.5%, long-term interest rate swaps will become highly attractive. We advise positioning for a steeper yield curve using interest rate swaptions to capture the gap between immediate policy adjustments and stronger long-term growth. Monitoring the upcoming macroeconomic policy statement will be critical for timing these derivative entries over the coming weeks.
