USD/KRW fell on Friday and over the week as firm export momentum and policy measures supported the won, while inflation remained elevated but eased. September CPI held at 2.9% year on year versus 3.1% in August, helped by petroleum price caps and a KRW193bn subsidy programme aimed at containing food prices during Chuseok. Core inflation slowed to 2.8% from 3.4%, yet headline inflation stayed above the Bank of Korea’s 2% target for a seventh consecutive month, leaving room for a hawkish bias even if rates are kept steady.
Trade data surprised to the upside: September exports rose 83.5% year on year versus a 62.5% consensus, following 68.7% in August; when calendar-adjusted, growth accelerated to 104.8% from 72.5%. Semiconductors led, with exports up 262% versus 209%. In FX, USD/KRW dropped 0.9% to 1,348 on Friday, taking the weekly fall to 0.8%, with reports of exporter dollar selling and a softer USD adding support. After back-to-back 25bp hikes in July and August, the policy rate is expected to be held at 3.0% in October, while the government plans KRW12tn of October bond issuance, KRW5tn less than first planned, citing stronger tax revenues and the option of emergency buybacks.
Opportunities In Shorting USD/KRW For Derivative Traders
We see a strong tactical opportunity for derivative traders to short USD/KRW in the coming weeks. South Korea’s export engine remains incredibly resilient, particularly in the semiconductor sector, which continues to drive heavy US dollar inflows as domestic firms repatriate their global earnings. This consistent corporate dollar-selling pressure provides a natural ceiling for the currency pair, making rallies in USD/KRW prime targets for short-sellers.
This bearish view on USD/KRW is further supported by the Bank of Korea’s relatively hawkish posture compared to other major central banks. While inflation has moderated closer to the central bank’s 2% target, policymakers remain highly alert to household debt and financial stability risks. Traders using options can take advantage of this yield support by buying put options on USD/KRW, targeting a push back toward the 1,310–1,320 range.
Fiscal Policy And Bond Market Dynamics Support The Won
Additionally, the South Korean government’s proactive fiscal management is stabilizing the domestic bond market. Reduced government debt issuance, funded by strong corporate tax revenues from the technology upcycle, has limited local bond yields from spiking disruptively. For derivative traders, this calm in the fixed-income space reduces volatility and supports a steady, appreciating trend for the Korean Won against a softening US dollar.
