South Korean Won Forecast: Record Semiconductor Exports Support KRW as Fed Risks Persist

Contributor: Currency Hedger | Market Analysis: Louis Roche, Today Markets

The South Korean won is trading around 1,333 per US dollar, reaching its strongest level since October 2024 as record export performance, robust semiconductor shipments and a trade surplus strengthen the currency’s outlook. South Korea’s technology-driven export growth is providing a solid fundamental foundation for the won, while easing oil prices may offer additional support by reducing pressure on the country’s import bill.

However, the won’s advance faces important obstacles. Elevated US Treasury yields and expectations of further Federal Reserve tightening continue to support the dollar, while renewed Houthi attacks on Saudi Arabia introduce fresh geopolitical uncertainty. For the coming sessions, the balance between South Korea’s export strength and the US interest-rate outlook is likely to determine whether the won can extend its recovery.

Market Snapshot

1. Semiconductor Exports Strengthen the Won

South Korea’s export performance is providing a powerful source of support for the won. Exports reportedly more than doubled year-on-year to a record USD 26.1 billion during the first 10 days of October, with semiconductor shipments rising 170.9% to USD 12.1 billion.

The strength of semiconductor exports is particularly significant because the sector is central to South Korea’s external earnings and international trade position. Strong overseas demand can increase foreign-currency receipts, support the trade balance and improve market confidence in the country’s economic outlook.

The reported USD 3.8 billion trade surplus adds to this positive picture. If export momentum persists through the remainder of October, the resulting improvement in external balances could help sustain demand for the won.

Nevertheless, the first 10 days of the month represent only a partial reporting period. Traders will need to assess whether the exceptional growth rate is sustained in the full-month figures before concluding that the export acceleration represents a durable trend.

2. US Treasury Yields and Fed Policy Limit Further Gains

Despite South Korea’s strong trade performance, the won remains sensitive to US monetary policy. Elevated Treasury yields can make dollar-denominated assets more attractive, supporting the US currency and limiting demand for emerging Asian currencies.

The prospect of further Federal Reserve tightening adds another layer of uncertainty. If US inflation or economic data reinforce expectations of higher interest rates, the dollar could strengthen even as South Korea’s external accounts improve.

Conversely, softer US inflation data or a more accommodative Fed outlook could ease pressure on the won by reducing upward pressure on Treasury yields and the dollar.

For USD/KRW, the key question is whether South Korea’s export advantage can outweigh the influence of US yields. A sustained decline in the pair would indicate continued won strength, while a rebound would suggest that dollar demand is regaining control.

3. Lower Oil Prices Offer Additional Support

Easing oil prices may provide another positive factor for the South Korean currency. As a major energy importer, South Korea is exposed to changes in international crude and fuel prices. Lower energy costs can reduce the import bill, ease inflationary pressure and improve the country’s terms of trade.

Market expectations of increased Russian diesel supplies have contributed to hopes of improved global fuel availability. US President Donald Trump has also claimed that Russia and Ukraine reached an immediate energy ceasefire, although the details and implementation of that claim remain uncertain.

If energy prices remain lower, South Korea could benefit from reduced external cost pressures. However, this support is not guaranteed: fuel prices remain vulnerable to supply disruptions, shipping constraints and geopolitical developments.

4. Middle East Tensions Remain a Market Risk

Renewed Houthi attacks on Saudi Arabia introduce a risk that could complicate the improving energy-price outlook. Any escalation affecting regional infrastructure or shipping routes could push oil prices higher and increase uncertainty across global markets.

A renewed rise in energy prices could weaken the won by increasing South Korea’s import costs. At the same time, a broader risk-off environment could encourage investors to favour the US dollar over Asian currencies.

The impact will depend on whether geopolitical tensions lead to actual disruptions in energy flows or remain a source of market uncertainty. Traders should therefore monitor developments in the Middle East alongside export data and US economic releases.

Technical Outlook: USD/KRW Around 1,333

With the dollar trading at approximately 1,333 won, the pair is near a level consistent with the won’s strongest position since October 2024, according to the supplied market report. Because no verified current chart levels have been provided, precise technical support and resistance should be confirmed against live pricing before publication or trading decisions.

Bearish USD/KRW scenario — further won strength: Continued export momentum, sustained semiconductor demand and softer US yields could place additional downward pressure on USD/KRW. A sustained move below the current trading area would reinforce the view that the won is extending its recovery.

Bullish USD/KRW scenario — dollar rebound: Stronger-than-expected US data, rising Treasury yields or renewed geopolitical stress could revive dollar demand. A sustained move higher in USD/KRW would signal that external pressures are outweighing South Korea’s favourable trade performance.

Neutral scenario — consolidation: The pair could trade within a relatively narrow range as markets balance robust Korean exports against uncertainty over the Fed and global energy prices. Confirmation from full-month trade figures and upcoming US data would help determine the next directional move.

South Korean Won Forecast for the Coming Sessions

The near-term outlook for the won is cautiously constructive, supported by strong semiconductor exports, a reported trade surplus and the potential benefit of lower energy prices. These factors provide a fundamental basis for further currency strength if they persist.

However, the pace of the won’s appreciation may slow if US Treasury yields remain elevated or the Federal Reserve signals that monetary policy will stay restrictive. Geopolitical escalation could also reverse the benefit of lower oil prices and trigger renewed demand for the dollar.

Three developments are likely to shape the coming sessions:

• South Korean trade data: Confirmation that export strength extends beyond the first 10 days of October would reinforce the positive outlook for the won.
• US inflation and interest-rate expectations: Softer data and falling Treasury yields could support further won gains, while stronger readings could lift USD/KRW.
• Oil prices and geopolitical risk: Lower energy costs would be supportive for South Korea’s external balance, but renewed disruption could undermine that advantage.

Overall, the won has a favourable domestic backdrop, but a sustained advance will depend on whether export strength can offset the pull of higher US yields and renewed global uncertainty.

Analysis — Louis Roche, Today Markets

South Korea’s export performance, particularly the surge in semiconductor shipments, is strengthening the fundamental case for the won. The reported trade surplus suggests that external demand is providing meaningful support, while lower oil prices could offer a further benefit to an energy-importing economy.

The main challenge is the international interest-rate environment. If US yields remain elevated, the dollar may continue to attract capital despite South Korea’s improving trade position. Geopolitical risks also mean that energy prices and market sentiment could change quickly.

The outlook therefore favours the won, but with caution. Continued export strength and a softer dollar would provide the clearest conditions for further appreciation. A renewed rise in US yields or energy prices could instead trigger a rebound in USD/KRW.
