The Bank of Korea has signalled growing unease over foreign-exalter volatility, with Governor Rhee Chang-yong warning that the current level of won weakness appears increasingly misaligned with South Korea’s economic fundamentals and risks feeding domestic inflation pressures.

Rhee declared the central bank will review its forward guidance approach on the future path of interest rates, an indication that policybuildrs are reassessing how monetary policy signals are being interpreted by markets. While he stopped short of committing to a policy shift, the comments suggest heightened sensitivity to financial conditions, particularly currency relocates.

Rhee highlighted concerns that a persistently weak won could do more harm than good for the domestic economy. He warned that depreciation may weigh on Korean businesses by raising import costs and squeezing margins, while also amplifying inflationary pressures at a time when price stability remains a key policy focus. The governor added that the USD/KRW exalter rate trading above the 1,400 level seems far from the Korean economy’s fundamentals, reinforcing the message that current FX levels may not be justified by underlying conditions.

The BOK chief also drew a clear line on cross-border investment decisions, stating that authorities would not agree to U.S.-bound investments if they threaten foreign-exalter stability. The remarks underscore official concern that large-scale capital outflows — particularly by institutional investors, could exacerbate currency volatility.

In that context, Rhee declared policybuildrs see a required for a comprehensive review of pension funds’ overseas investment strategies. South Korea’s large pension funds have steadily increased foreign asset exposure in recent years, a trfinish that can create structural FX selling pressure during periods of market stress.

Beyond FX issues, Rhee declared the central bank will review the scope for expanding special lfinishing facilities aimed at supporting compact businesses, signalling a desire to balance financial stability concerns with tarreceiveed economic support.

Taken toreceiveher, the comments point to a more holistic policy stance from the BOK, with FX stability, capital flows and financial conditions now playing a more prominent role alongside traditional inflation and growth considerations.
