South Korean CEX volumes drop over 40%

TLDR

Spot trading on major South Korean crypto exchanges has dropped by over 40%, signaling a sharp cooldown in one of cryptos most active retail markets.

1. Upbit and Bithumb volumes are down roughly 39% to 49% from late 2025 levels, cutting daily activity by hundreds of millions of dollars.
2. The slump is tied to a global cooldown, weaker retail speculation, and regulatory uncertainty in South Korea, which threatens exchange revenue and altcoin liquidity.
3. Recovery likely depends on new catalysts or clearer rules; until then, traders should assume thinner liquidity and more venue risk in Korean markets.

Deep Dive

1. How Big The Volume Drop Is

According to recent data, Upbit and Bithumb have seen a 40%+ contraction in average daily trading volume versus the second half of 2025.

Upbits Q1 2026 daily average volume was about $1.55 billion, down 38.8% from roughly $2.53 billion in H2 2025, while Bithumb dropped 44% to about $647.31 million. From 1 Jan to 20 May, Upbits average fell 45.5% and Bithumbs 48.5% relative to that H2 2025 baseline, confirming a sustained 40%+ decline in average daily volume.

2. Drivers And Market Impact

The article attributes the downturn to a broad crypto market cooldown after a very active late 2025, alongside reduced retail speculation and a risk off stance among traders.

Regulatory uncertainty around South Koreas evolving crypto and stablecoin framework also weighs on activity by making both users and platforms cautious about aggressive growth. With fewer strong bullish narratives in early 2026, casual traders have less reason to chase altcoins on local exchanges.

For centralized exchanges that earn mainly from trading fees, this volume shock compresses margins. Large venues like Upbit can absorb it more easily, but smaller local platforms are more exposed, and altcoin order books can become meaningfully thinner.

3. What To Watch Next

Several factors could shape what happens from here:

1. Regulation and policy clarity. Ongoing work on virtual asset and stablecoin rules will influence how comfortable Korean banks, issuers, and exchanges feel supporting new products.
2. Competition and consolidation. Reports that global players like OKX are eyeing Korean venues such as Coinone hint at possible ownership changes and liquidity reshuffling.
3. Global cycle and local risk appetite. Korea has historically been a high beta retail market. A renewed global uptrend or local hype wave could revive volumes, while continued macro stress would reinforce the slowdown.

Conclusion

The 40%+ drop in South Korean CEX volumes reflects both a cooler global crypto environment and Korea specific regulatory and sentiment headwinds.

Until clearer rules or fresh narratives emerge, Korean exchanges likely operate with tighter margins and thinner books, especially in smaller coins, which makes venue selection and liquidity awareness more important for anyone tracking this market.
