South Korea's largest won-denominated cryptocurrency exchanges have experienced a dramatic decline in trading activity over the past year, a shift that coincides with a sharp rebound in the country's equity market, according to an analysis by Cointelegraph. The development marks a notable reversal for a market that has historically ranked among the world's most active for digital asset trading, with Korean retail investors at times driving premiums on locally listed tokens — a phenomenon widely tracked as the "kimchi premium."

Cointelegraph examined CoinGecko historical 24-hour volume data for five major exchanges — Upbit, Bithumb, Coinone, Korbit, and Gopax — comparing seven-day periods in July 2025 and July 2026. By calculating the average daily volume for each platform and then applying a simple unweighted average of the five year-over-year declines, the analysis produced an estimated average drop of approximately 77% across all platforms. On a combined basis, aggregate average daily volume fell roughly 89%, from $2.82 billion to $305 million over the comparable July windows.

The two figures — the roughly 77% per-exchange average and the roughly 89% combined contraction — describe the same downward trend through different weighting methods. The 77% figure represents the arithmetic average of declines across the five exchanges, with each platform weighted equally regardless of its baseline trading volume. The 89% combined figure reflects the total contraction when aggregating average daily volume across all platforms.

Equity Market Surge Draws Retail Attention

South Korea's benchmark stock index, the KOSPI, rose 114.44% over the 12 months to July 22, according to Yahoo Finance data, even after retreating from a June peak. Cointelegraph frames the simultaneous decline in won-based crypto trading activity and the surging equity market as evidence that retail investors may be reallocating attention toward stocks. Korean retail investors — known locally as "ants" for their collective market influence — have historically moved quickly between asset classes in search of returns, making the rotation from crypto to equities consistent with established behavioral patterns.

Separate reporting from ZDNet Korea cited an 88% year-on-year decline in combined daily volume across the five exchanges as of Monday. ZDNet Korea also linked the volume contraction to weakened fee income, noting that some platforms have responded by selling portions of their cryptocurrency holdings. The outlet specifically reported that Korbit raised approximately 1.6 billion won (around $1 million) by selling 15 Bitcoin (BTC) and 60 Ether (ETH).

The revenue implications are significant for South Korea's exchange ecosystem. In a retail-dominated market, platforms rely heavily on trading fees, and sustained volume declines can tighten revenue across the industry, making it harder for smaller operators to remain competitive during quieter periods. The pressure is particularly acute given that Upbit, operated by Dunamu, has long held a dominant market share, leaving smaller exchanges more vulnerable to contraction.

Investor Fatigue and Structural Transition

A report from Tiger Research, published on CoinGecko and updated April 17, argued that the decline in South Korean crypto activity reflects factors beyond market price movements. The report identified "recycled narratives" and projects that failed to deliver as contributors to investor fatigue, which can reduce willingness to participate even when opportunities exist.

Tiger Research also noted that the KOSPI rally broadened the range of return options available to retail traders, raising the opportunity cost of staying in crypto. When equities perform strongly, retail crypto participation may become more selective — favoring specific themes or entry points rather than sustaining broad, continuous trading volume. That selectivity can reduce average exchange liquidity even if overall crypto sentiment remains intact.

The report characterized the market as undergoing a "structural transition," with retail activity retreating while institutions begin to enter. Tiger Research said banks and financial groups had already been positioning around won-denominated stablecoins, tokenized real-world assets (RWAs), and exchange investments before final legislation was enacted. The trend aligns with broader developments following the implementation of South Korea's Virtual Asset User Protection Act in July 2024, which established the first comprehensive legal framework for digital assets in the country and set the stage for institutional engagement.

However, Tiger Research cautioned that institutional participation is not a seamless replacement for retail volume. The report described institutions as "finding their footing," suggesting a gradual and uneven transition rather than an immediate equalization of trading activity. The central uncertainty for exchanges and investors is whether institutional flows can scale quickly enough to offset the liquidity gap created by reduced retail trading.

If the divergence between equity and crypto market participation persists, South Korea's exchange landscape may face further consolidation pressure. At the same time, tokenized asset infrastructure and stablecoin-linked products could gain relative prominence as developers and financial institutions seek activity beyond spot retail trading.
