BOK Signals Rate Hike at 2.5% as Shin Sees Limited Korean Stock Downtrend

Q: With Korea's economy riding an AI chip boom, could a rate hike backfire if the tech market cools?

Yes. A Bank of Korea rate hike could backfire if the AI-chip cycle weakens, because South Korea’s current growth is unusually concentrated in semiconductors. The case for tightening is clear: inflation has risen to 3.1% in May, the BoK expects it to move toward 3.5%, and growth has been stronger than expected, with first-quarter GDP up 1.7% quarter on quarter. Semiconductor exports have surged nearly 170% and now make up about 42% of total exports. That gives the BoK room to argue the economy can absorb higher rates. But that strength is also the main risk. If the global AI and memory-chip boom cools, Korea’s export engine could slow abruptly. A rate hike would then hit at the same time as weaker external demand, raising borrowing costs for companies and households just as income and confidence soften. That matters in an economy already sensitive to household debt, property prices and exchange-rate volatility. The danger is less that one 25-basis-point move would derail the economy on its own, and more that policy could become pro-cyclical if the BoK tightens into a turning tech cycle. Higher rates can also weigh on tech valuations and investment appetite globally, especially in sectors priced for rapid growth. Still, the BoK is reacting to real inflation and financial-stability risks, including energy-driven price pressure and won weakness. The key question is timing: if chip demand stays strong, a hike looks manageable; if the AI boom fades quickly, it could prove mistimed.

Shin Hyun-song told parliament a Bank of Korea rate increase will be needed at an appropriate time, while arguing the risk of a sustained slide in Korean stocks is limited.
Inflation remains above target, growth is improving and financial-stability risks are rising, the BOK said, reinforcing its shift from holding the benchmark rate at 2.5% since July last year.
Semiconductor exports tied to the AI boom, higher chip prices and earnings upgrades for chipmakers have strengthened the economy and should help cushion equities despite volatility from global monetary policy and AI concerns.
The won has stayed in the low- to mid-1,500-per-dollar range despite a large current-account surplus, with Shin citing foreign stock selling and broad dollar strength as key market risks.
Shin also urged safeguards for any stablecoin rollout, warning they could bypass South Korea's foreign-exchange regime unless issuance is led by bank consortia and overseen by a statutory policy body.
