South Korea's stock market falls as cryptocurrency trading volume surges

South Korea's crypto market surges in trading volume after stock market crash

Trading activity in the South Korean cryptocurrency market has risen sharply this week after the Korea Composite Stock Index (KOSPI) fell sharply, highlighting how quickly the stock market sell-off has turned attention to digital assets and related products traded overseas. According to Upbit data, trading volume between the Korean won and the TEDA coin (USDT) rapidly expanded during the index decline.

At the same time, analysts pointed to another parallel development: Bitcoin has shown relative strength compared with large U.S. equity benchmarks despite macro pressures that have suppressed risky assets. Bitwise's latest research believes that as the financial environment tightens, the performance of this cryptocurrency has become increasingly eye-catching.

Key Points

The KRW/USDT transaction volume on Upbit was close to 200 billion won (approximately 140 million USDT) on July 29, compared with only approximately 20 million USDT on July 25, an increase of approximately 600%. Local analysts attributed the surge to the rotation of funds from South Korea's stock market to cryptocurrency trading, or equity-linked derivatives traded through overseas channels. Previous KOSPI volatility showed a similar pattern: Upbit recorded a surge in trading volume after the index fell 10% in a single day on July 14. Bitwise said that Bitcoin has outperformed the major ultra-large-cap stocks in the United States, and its trend has remained basically "flat" since the semiconductor sector peaked at the end of June.

Stock market decline drives KRW/USDT trading surge

Upbit's exchange data provides the most direct evidence of the connection between the stock market and the crypto market. According to reports citing Upbit KRW/USDT market data, trading volume between KRW and USDT climbed rapidly between July 25 and 29. On July 29, transaction volume was close to 200 billion won (approximately 140 million USDT), compared with only approximately 20 million USDT on July 25. The surge coincides with a broader decline in South Korea's KOSPI index. The index's sharp decline during the week-reports say it fell nearly 18%-was related to weakness in chip-related stocks, especially chipmaker stocks. This means for investors: When liquid, familiar markets begin to fall rapidly, some participants will look for alternatives that can be traded at any time and provide spot exposure and leverage strategies.

Analysis cited by local reports pointed out that funds may rotate from stocks to cryptocurrencies during the sell-off, or traders seek derivatives linked to South Korean stocks through overseas exchange platforms. The same report also highlighted that funds may tend to be transferred to overseas exchanges or personal wallets to trade perpetual stock futures. Cho Yoon-sung, senior fellow at Tiger Research, said: "There is a possibility that there is an increased need to transfer funds to overseas exchanges or personal wallets in order to trade perpetual stock futures." In other words, the surge in KRW/USDT trading volume looks less like random intraday trading noise and more like a measurable by-product of traditional market pressures. When stock markets deteriorate, traders can quickly reallocate positions-especially in an environment where cryptocurrencies already serve as a highly volatile and risky market.

Stock market sell-off and "overseas" trading paths

South Korea's cryptocurrency ecosystem is closely linked to the way local investors express risk. The report emphasized that the country's market remains highly active, especially with young participants expressing a preference for leveraged products. This preference tends to amplify the trading volume response when hitting adjacent assets such as stocks. In addition, there is a structural factor: some investors may prefer to gain certain equity-linked exposure through crypto-native derivatives offered by overseas platforms. As KOSPI volatility increases, the willingness to transfer funds to directly trade cryptocurrencies or use perpetual contracts linked to stock themes may increase.

It is worth noting that this surge is not a new act. According to reports, at the beginning of this month, after KOSPI fell 10% in a single day on July 14, Upbit recorded a significant surge in trading volume. This creates a pattern: Large, rapid stock market volatility has previously coincided with a surge in cryptocurrency trading activity.

Bitcoin's resilience under semiconductor pressure

While Korean Won-denominated trading volumes have risen sharply due to turmoil in South Korea's stock market, analysts in other regions are studying whether macro weakness will "spill over" into cryptocurrency performance. Andre Dragosch, head of European research at Bitwise, believes that Bitcoin's performance is not a fragile extension of semiconductor trading. In comments he shared on social media (quoted by reports), he pointed out that since the semiconductor sector peaked at the end of June, Bitcoin has been basically in range fluctuations-"roughly flat." His view is that the contagion of expectations triggered by semiconductor-driven repricing of risk has not materialized as some market participants might have expected.

A broader analysis released by Bitwise earlier this week strengthens this view through relative performance. The company called Bitcoin's performance against a group of ultra-large-cap U.S. stocks a "significant excess return." In the report, Bitwise pointed to benchmarks that included exposure to large technology stocks and even SpaceX (SpaceX was mentioned in the article as part of the comparison set). Bitwise's argument goes beyond simple relative returns. It links Bitcoin's strength to early signals that the asset may have been priced in advance in future monetary policy easing-even if inflation remains a concern and the risk of short-term interest rate hikes remains. The company also uses the well-known "macro canary" metaphor to describe Bitcoin's sensitivity to macro conditions.

Bitwise pointed out in its analysis that Bitcoin continues to show "significant excess returns and resilience" compared to the "Gorgeous Seven" and U.S. ultra-large-cap stocks such as SpaceX, and said that this relative strength is "more eye-catching" in a tightening financial environment. This is important for investors because it shows that the behavior of cryptocurrencies is not simply determined by the same narrative that drives the stock market. If Bitcoin's relative strength persists, it could mean that the market no longer sees Bitcoin as an alternative to stocks, but sees it as an independent macro tool that responds to different expectations, especially those surrounding future policies.

What should traders focus on next

The short-term question is whether the KOSPI-driven surge in trading volume is the short-term reaction to a sharp week or whether stock market volatility is driving South Korea's cryptocurrency activity again. Traders should pay attention to whether KRW/USDT trading volumes remain high in subsequent trading days and whether Bitcoin's excess returns relative to U.S. ultra-large-cap stocks are maintained as the macro narrative shifts.
