  • Won strengthens 0.61% to 1,365.24 as exports support BoK stance

Yesterday's Recap

South Korean markets saw the won strengthen further against the dollar, closing at 1,365.24 after a 0.61% gain driven by robust export performance. KOSDAQ advanced 1.11% to 836.27 while Samsung Electronics rose 2.53% to 283,500 and SK Hynix added 0.71% to 1,853,000. The Korea 3-year government yield eased 2 basis points to 4.04% and the 10-year yield held steady at 4.46%.

No economic data releases occurred on 22 September, shifting attention to news flow including the Asian Development Bank’s upward revision of 2026 GDP growth to 3.2%. Commerzbank highlighted that the export surge underpins the Bank of Korea’s current policy stance. Authorities maintained subsidized fuel prices ahead of the Chuseok holiday despite mounting fiscal costs, and the BoK supplied 3.6 trillion won in liquidity to support holiday demand.

Brent crude eased 0.92% to 98.34 while gold declined 1.21% to 4,323.40.

The Day Ahead

Markets face a data-empty session on 23 September with no scheduled releases or Bank of Korea events. Focus will remain on won dynamics and external developments including Iran deal uncertainty affecting broader Asia FX. Semiconductor names may continue to draw attention after yesterday’s gains in Samsung and SK Hynix.

The BoK’s ongoing test of 24-hour won settlement for foreign investors could generate incremental market commentary. Participants will also monitor any updates on the 565 billion won owed to Korean defense and construction firms by Iraq. Bitcoin fell 2.21% to 84,265.83, reflecting softer risk appetite that could influence equity flows.

Other Economic Notes

The won’s recent advance has been described by the Bank of Korea as fast but not excessive, aligning with export-driven resilience that reduces pressure for near-term policy easing. A 25 basis point rate hike would add roughly 7 trillion won in interest costs for households and businesses, underscoring the BoK’s caution on tightening. Fuel subsidies extended through the holiday period highlight fiscal trade-offs amid elevated global energy prices.

The stronger won coincides with export momentum that Commerzbank views as supportive of the Bank of Korea’s hold stance. Global commodity moves showed Brent crude easing while gold declined, potentially capping imported inflation pressures for Korea.

Global Macro News

Asia FX markets remained largely range-bound outside the won and rupiah, both of which advanced amid uncertainty over an Iran nuclear deal. The stronger won coincides with export momentum that Commerzbank views as supportive of the Bank of Korea’s hold stance. Global commodity moves showed Brent crude easing 0.92% while gold declined 1.21%, potentially capping imported inflation pressures for Korea.

Bitcoin’s 2.21% drop may signal reduced risk appetite that could affect equity flows into KOSDAQ technology names. Other regional currencies showed limited reaction, leaving the won’s outperformance as the dominant theme for Korean financial conditions. External developments around Middle East diplomacy and U.S.

policy signals will likely dictate near-term won volatility.

BoK Watch

The Bank of Korea has noted that the won’s rise, while rapid, does not yet appear excessive, consistent with export strength that bolsters the case for maintaining the 2.81% base rate. Recent communications continue to emphasize financial stability risks, including the 7 trillion won additional household and corporate interest burden from even a modest 25 basis point hike. The BoK’s decision to supply 3.6 trillion won ahead of Chuseok reflects liquidity management priorities without signaling a shift in the policy stance.

Testing 24-hour won settlement aims to improve foreign investor access and reduce settlement frictions, a technical measure that supports capital flow stability. ↓ p.3

Continuation

BoK Watch (continued)

With August CPI at 3.09%, the committee remains focused on balancing inflation persistence against growth momentum revised higher by the ADB to 3.2% for 2026. Market pricing shows little expectation of near-term moves, with front-end yields easing only modestly.
