Beyond Tether: The Growing Battle for Stablecoin Market Dominance

South Korea's major exchanges doubled their dollar-pegged listings from three to six in twelve months, per finance.biggo.com reporting, while payments provider BVNK logged a 263x jump in wallet volume across 2025 as companies swapped traditional banking infrastructure for embedded stablecoin accounts. For market participants, the question is no longer whether dollar stablecoins gain traction — it is which issuer captures the next leg of institutional and corporate flow.

Korean Order Books Diverge

Upbit added Ripple's RLUSD on July 29, bringing its won-market stablecoin count to six alongside USDT, USDC, USDS, USDE, and World Liberty Financial's USD1. Coinone matched that roster after preemptively listing RLUSD in March; Bithumb trails with five and no RLUSD support. A year ago the same venues carried only USDT, USDC, and USDS.

The competition is already producing measurable volume shifts. On the morning of July 28, USDT turnover on Upbit hit roughly 160 billion won (~$110.1 million) — about four times the ~64 billion won (~$44 million) recorded on Bithumb in the same window. Upbit launched an eight-day fee waiver across all six stablecoins on July 26, running through August 2, and the lift in stablecoin trading was immediate. Industry sources quoted by finance.biggo.com note that stablecoins generate baseline demand regardless of market conditions, with investors parking funds in dollar-pegged assets while waiting out the current downturn.

Enterprise Rails Outpace Retail Listings

BVNK's data shows wallet volume increased 263x during 2025 as companies moved from correspondent banking chains to embedded stablecoin accounts. For corporate treasury and merchant acquisition teams, the shift compresses settlement windows and cuts cross-border friction — the kind of cost line items that show up on quarterly operating reviews. The growth rate suggests that enterprise adoption is now scaling faster than the retail exchange listings cycle, with payment processors and wallet providers acting as the default onboarding layer for businesses that have no direct relationship with a stablecoin issuer.

What to Watch

The Treasury's decision to ban interest on stablecoins, reported by Business Daily, signals that regulators treat yield-bearing stablecoins as direct competition to bank deposits. That constraint narrows the product roadmap for new entrants and reinforces USDT's existing positioning as a transactional, non-yielding instrument. The practical question for settlement teams is which stablecoin issuer secures the deepest banking and processor integrations over the next two quarters — and whether providers like BVNK become the default corporate front end. The same rails are now extending into commodity and energy markets settlement flows, where cross-border trading desks are beginning to test stablecoin settlement against traditional correspondent chains. For incumbents, the near-term risk is not losing the retail trading crown but losing the enterprise plumbing that determines where the next billion in volume parks.
