- Stablecoin reserves on exchanges reached record highs, signaling massive liquidity ready to fuel upcoming DeFi and DEX growth.
- Low Stablecoin Supply Ratio combined with rising reserves indicates strong potential buying power across decentralized markets.
The surge in stablecoin reserves has again set a new record, raising a major question among market participants: is this the beginning of a boom in activity in the DeFi and DEX space?
According to analysts at XWIN Research Japan on CryptoQuant, reserves of ERC20-based stablecoins on exchanges reached nearly $59 billion by September 2025.
This figure is not just a statistical record, but rather a reflection of purchasing power waiting to be unleashed. Historically, similar phases often precede broader market rallies.

Furthermore, the analysis also highlighted the Stablecoin Supply Ratio (SSR), which remains at a low point compared to the 2019–2021 cycle. This ratio measures the ratio of Bitcoin’s market capitalization to the stablecoin supply.
When the SSR is low while reserves are increasing, this condition usually indicates an abundance of “fuel” in the market. In many previous cases, this combination has signaled a market environment ready to trigger a bullish trend. The question is, when will the trigger be pulled?

Netflows and Regulation Shape the Next DeFi Wave
Stablecoin movements cannot be measured solely by reserves. XWIN Research Japan emphasizes the importance of monitoring netflow, or the inflow and outflow of stablecoins on exchanges.
When inflow increases, it means many traders are preparing to deploy capital on CEXs. However, when large outflows occur, stablecoins typically flow to DeFi protocols, liquidity pools, or even the payments sector.
If this pattern occurs in conjunction with a low SSR, the opportunity for capital to shift to DeFi could be wide open. Doesn’t this sound like a ticking time bomb waiting to explode?
Interestingly, stablecoin dynamics have been in tandem with regulatory developments. In early August, the United States Securities and Exchange Commission (SEC) clarified its stance on liquid staking. This move was seen as removing a major regulatory hurdle and strengthening validation of DeFi’s growth.
The market responded by recording over $66 billion in total value locked (TVL) in the liquid staking sector, with Ethereum accounting for approximately $51 billion. Lido, the largest protocol, controls over $31 billion in ETH.
Traditional Giants Downplay Stablecoin but See Limited Uses
However, the views of traditional global players do not align with the optimism of the crypto community. The CNF reported that in early August, Visa and Mastercard asserted that stablecoins were still too small to challenge the dominance of their payment networks.
Furthermore, both companies believe that stablecoins are more useful in countries with fragile local currencies than in mainstream markets. This view may sound dismissive, but it can also be interpreted as an opportunity: emerging markets could actually be the most fertile ground for stablecoin adoption.
Returning to the latest stablecoin news, historical patterns show that periods when stablecoin reserves are abundant, SSR is low, and capital flows shift away from exchanges often end with strong rallies in the DeFi and DEX ecosystems.
