South Korea’s money supply growth slowed to 7.1% in January. This was down from 7.3% in the previous period.
The slowdown in South Korea’s M2 money supply growth to 7.1% in January is a signal we can’t ignore. It suggests a tightening of financial conditions, even without an official interest rate hike from the Bank of Korea (BOK). This trend points to less liquidity available in the system, which typically precedes a cooler economic environment.
This aligns with the latest February 2026 inflation report, where core CPI remained sticky at 3.2%, continuing to exceed the central bank’s 2% target. The BOK has maintained its policy rate at 3.5% for over a year, and this persistent inflation gives them no reason to consider cutting rates soon. This reinforces the idea that monetary policy will remain restrictive for the foreseeable future.
For our strategies, this points towards a stronger Korean won. As long as the BOK maintains this tighter stance while other major central banks appear more dovish, the interest rate differential should support the currency. We are therefore looking at opportunities in KRW/USD call options or futures contracts betting on won appreciation.
This environment is also a headwind for the KOSPI index. Reduced liquidity and the prospect of borrowing costs staying high will likely weigh on corporate earnings and equity valuations. Consequently, we see value in protective strategies, such as buying puts on the KOSPI 200 index or establishing bearish put spreads for the second quarter.
We must remember how the market incorrectly priced in significant rate cuts throughout the second half of 2025, only to be disappointed by the BOK’s resolve. That experience suggests the market may again be too optimistic about a policy pivot. This makes short-term bond futures, which would rally on rate cuts, a risky proposition right now.
