Second straight rate hike for Asia’s number-three economy as Nvidia-led AI expansion continues

The Bank of Korea delivered its second consecutive 25-basis-point rate increase, lifting its benchmark rate to 3% while also revising its growth outlook higher. The move underscores a delicate balance: stronger exports fueled by AI-related demand are supporting the economy, yet policymakers remain alert to inflation and household debt. By raising rates alongside a more optimistic forecast, the central bank signals that containing price pressures takes priority over supporting an already firming recovery.

South Korea, Asia’s third-largest economy, is a key producer of memory chips and electronics that feed global data-center buildouts. Nvidia’s latest quarterly results, released this week, reinforced that demand for AI infrastructure remains robust. For Korea, that is a critical external tailwind—helping explain the improved growth projection and giving the Bank of Korea room to tighten policy without derailing momentum.

For markets, the takeaway is the evolving link between AI investment and traditional monetary policy. A sustained AI capex cycle may support Korean exporters and the won, but it also complicates central-bank decisions as rate setters weigh growth strength against inflation risks. Observers will watch upcoming export data and the BOK’s commentary for clues on how long this tightening path lasts.
