Reserve boost plans drive positive sentiment, offsetting market intervention concerns

South Korea's government and the Bank of Korea are considering a significant purchase of long-term U.S. Treasuries to boost foreign exchange reserves and ease trade-related pressure. This plan was discussed at a recent Korea-U.S. finance and monetary authorities meeting, receiving positive feedback from the U.S. side. Authorities are evaluating methods to minimize direct impacts on the USD/KRW exchange rate, including acquiring dollars from exporters in the over-the-counter market instead of direct market action.

Anton Kharitonov, expert at Traders Union, notes the recent optimism on South Korea’s Treasury purchases but warns the rally in USD/KRW remains tepid. He highlights that price action is capped by longer-term resistance and overbought oscillators signal a likely pullback. Kharitonov points out that authorities’ intervention is designed not to spark direct currency volatility, revealing latent caution in policy. Technical momentum up to ₩1,375 is at risk without a sustained catalyst. "Despite the bullish bias, I see limited upside as technical and policy hurdles constrain sustained gains," he says.

Viktoras Karapetjanc, expert at Traders Union, sees South Korea’s plan to boost its reserves through U.S. Treasuries as a major confidence signal for the market. He believes institutional support and collaborative policy with the U.S. underpin a robust environment for further gains in USD/KRW. Karapetjanc notes the bullish structure above short- and medium-term averages and expects constructive flows to sustain upward pressure. "This market offers multiple bullish setups — I expect further growth if resistance at ₩1,375 is cleared decisively," he asserts.

Jainam Mehta, market strategist, observes that USD/KRW’s technical structure favors higher levels, but overheated oscillators point to increased correction risk. He suggests that a potential breakout above ₩1,375 may set off fresh momentum, while a reversal below ₩1,362 could trigger swift mean reversion. "Tactically, I would watch for contrarian pullback opportunities if sentiment shifts against the crowded long," says Mehta.

Short-term bullishness faces long-term resistance amid overheating signals

USD/KRW trades firmly above its 20-day and 50-day moving averages at ₩1,334 and ₩1,346, signaling short- to medium-term bullish momentum. The price remains below the 200-day moving average at ₩1,443, which marks ongoing long-term resistance. The nearest ceiling lies at ₩1,375, with a floor at today's high of ₩1,362. Momentum signals are mixed: MACD is neutral, the Average Directional Index indicates upward bias, and the Relative Strength Index is neutral. Both Stochastic RSI and Commodity Channel Index reveal overbought conditions, pointing to short-term correction risk. Bull/Bear Power shows buyers dominate intraday price action. The pair opened nearly flat and holds close to the session high, with daily volatility amplitude at 0.78%. The awesome oscillator is neutral. Overall, while price momentum shows strength toward the highs, several oscillators highlight the risk of overheating.

Earlier, analysts noted that USD/KRW was likely to consolidate as neutral technical signals tempered short-term bullish momentum, with the outlook shaped by official statements on currency intervention. The current article adds a new dimension by highlighting potential foreign reserve management strategies that could impact flows, positioning resistance at ₩1,375 as the key level to watch for any near-term breakout.
