Stablecoin supply reached a record $315 billion in Q1 2026 despite slowing growth, according to new data. While their share of total crypto trading volume hit a record 75%, underlying activity shifted sharply toward automated bots, which drove 76% of transaction volume. A divergence emerged between major issuers, with Circle‘s USDC growing while Tether‘s USDT supply contracted.
Stablecoins were a rare bright spot in an otherwise subdued crypto market in the first quarter. Total stablecoin supply increased by roughly $8 billion to a record $315 billion, marking the slowest pace of expansion since late 2023.
The data suggests investors rotated into stablecoins as a defensive strategy. Stablecoins accounted for 75% of total crypto trading volume during the quarter, which is the highest level on record.
Total stablecoin transaction volume topped $28 trillion, underscoring their primary role as the digital asset market’s liquidity layer. This volume in recent years has exceeded that of major payment networks like Visa and Mastercard combined.
Retail-sized transfers declined by 16% in the first quarter, the steepest drop on record. In contrast, automated activity surged, with bots accounting for approximately 76% of all stablecoin transaction volume.
One key takeaway was a widening divergence between major stablecoin issuers. The supply of Circle‘s USDC grew by roughly $2 billion, while Tether‘s USDT declined by about $3 billion.
Beyond USDC, much of the growth in stablecoin issuance was driven by yield-bearing products. The market for yield-bearing stablecoins is currently valued at around $3.7 billion, with daily trading volumes exceeding $100 million, according to data from CoinGecko.
