Hacks are no longer content with weakening DeFi, but they are already reshaping the balance of the stablecoin market. Within days, a series of major attacks triggered a massive shift of capital toward assets perceived as safest. In this climate of mistrust, Tether (USDT) clearly strengthens its dominant position against USDC, taking advantage of a reflex to protect investors. This shift reveals a deeper change in the stablecoin hierarchy.

In brief
- A wave of major hacks in DeFi is triggering a rapid movement of capital into assets perceived as the safest.
- The Drift Protocol hack, estimated at $285 million, acted as a trigger for this shift.
- Investors are massively shifting their funds to Tether, strengthening its dominant position in the market.
- The data confirms this trend with USDT rising faster against a slowing USDC.
DeFi hacks and the rush to USDT
The tipping point occurred following a series of attacks targeting DeFi protocols, including the major Drift Protocol hack on Solana, estimated to be worth around $285 million. Faced with these events, users quickly redirected their capital towards safer assets.
This dynamic directly benefited Tether. So, “Tether’s dominance over Circle’s USDC strengthens”in a context where investors are looking for liquid and proven solutions.
This movement immediately reflected in market data:
- USDT market cap is at an all-time high, up approximately 2.1% to nearly $188 billion;
- More moderate growth in USDC, limited to +1.4%;
- DeFi capital migration to USDT after security incidents;
- The proliferation of hacks, some of which attributed to groups linked to North Korea.
These elements reflect a rapid reaction of investors to risk, with an arbitrage in favor of the dominant asset in terms of liquidity.
A dynamic of domination reinforced beyond incidents
Beyond the immediate reaction to hacks, on-chain data reflects a more structural trend in the stablecoin market. Episodes of crisis amplify a reflex already anchored among investors: to favor assets offering the greatest market depth.
In this context, Tether benefits from a historical advantage, consolidated by its central role in crypto exchanges. This dominance grows stronger as tensions arise, as users turn to USDT as a fallback.
Such a development reveals a growing imbalance between the two main stablecoins on the market. While USDC remains firmly established, its slower growth reflects a relative loss of momentum during periods of stress. The observed differential is not based solely on recent events, but on a perception of risk and liquidity which is expressed more strongly during periods of uncertainty.
In the long term, these episodes question the ability of different transmitters to maintain trust in an environment where each incident acts as a life-size test. Tether's dominance, strengthened in these critical moments, could continue to expand if market conditions remain unstable, while reigniting the debate on the concentration of the stablecoin market and its implications for the crypto ecosystem.
