USDC flows surge on Ethereum: Inside the ‘strategic’ shift driving ETH’s 20% move

HODLer patience from the 2025 bear cycle finally seems to be paying off.

At the time, altcoins ended the cycle deep in double-digit losses, even though fundamentals stayed strong. Take the Fusaka upgrade. It was mainly focused on boosting Ethereum’s throughput.

The impact? Network transaction volume climbed 36% by year-end, even as ETH closed the year down 29%.

From a technical lens, that kind of volume expansion usually lines up with improving on-chain liquidity, as higher activity leads to better capital flow and stronger network usage.

In that context, Ethereum’s [ETH] 20% move over the past month looks less like a random spike and more like a strategic shift starting to play out.

As the chart above shows, Ethereum’s stablecoin flows are clearly rotating. Over the past month, USDT on-chain flow edged up just 1.46%, while USDC supply expanded by a much stronger 10.13%. That is almost a tenfold gap, suggesting liquidity is starting to favor USDC over USDT.

Backing this up, Santiment data shows the top 100 USDC wallets on Ethereum now hold $32.71 billion worth of USDC. Even more notable, the top six alone control just over 25.6% of the total supply, pointing to a high level of concentration among major holders.

Taken together, this signals a clear shift in liquidity positioning, as larger players steadily accumulate USDC and reshape how they deploy capital across the Ethereum network.

Naturally, this raises the question: Is this just a short-term rotation or a “strategic” shift that could set the stage for an ETH repricing?

USDC gains momentum as USDT shifts focus to Bitcoin

USDC flows on Ethereum have pushed its market share above 32%, while USDT has dropped below 50%.

However, this shift appears to be more than a short-term rotation. Over the past 30 days, Tether has deployed roughly $20 million into Bitcoin [BTC] Layer 1 infrastructure, reflecting a deliberate strategy to strengthen BTC’s role as a settlement layer.

Against this backdrop, the growing USDT flow on Ethereum does not look random.

Instead, this context is reinforced by the underlying data. USDC’s market cap has jumped roughly 30%, surpassing $80 billion to reach an all-time high since Circle’s IPO in late Q2 2025.

Moreover, Circle’s stock [CRCL] has surged 120% over the past 30 days, highlighting solid technical and market performance that backs the on-chain trends.

Taken together, Tether’s rotation toward Bitcoin, combined with Circle’s growing market share, shows that large players are strategically shifting how they deploy stablecoins on Ethereum.

 The result is clear: USDC’s roughly 10% gain over the past month aligns closely with ETH’s 20% price increase.

Notably, on-chain data reinforces this trend. CryptoQuant shows that ETH’s Total Value Staked (TVS) has climbed nearly 3% to an all-time high of 38 million ETH, while the total value of Real-World Assets (RWA) has risen about 6% over the same period.

In essence, the effects of Ethereum’s 2025 upgrades are showing up in its stablecoin activity, with USDC flows now feeding directly into on-chain activity. In this context, Ethereum’s market repricing is becoming increasingly tied to USDC flows, making it a key trend to watch.

Final Summary

• USDC supply has surged over 10% on Ethereum in the past month, supported by large holders and on-chain activity, signaling strategic rotation rather than a short-term move.
• ETH’s 20% price gain aligns with rising USDC flows, increased staking, and RWA growth, showing that Ethereum’s 2025 upgrades are driving stablecoin activity and influencing market repricing.
