Crypto traders have treated stablecoin supply like a buy signal. More USDT and USDC in the system, the theory goes, means more cash is waiting to move into BTC, ETH and other crypto assets.

That shortcut is getting unreliable.

Stablecoins still matter for trading liquidity. But they also do far more than sit in exchange wallets. The same assets get used for payments, remittances, settlement, and dollar access in markets where banking routes can be slow, expensive or restricted. When stablecoins grow for those reasons, the connection to near-term buying pressure weakens.

The Fed’s number and why it changes the “signal”

The Federal Reserve said stablecoin market capitalization grew by more than 50% since early 2025, reaching $317 billion as of April 6, 2026. The point is not that stablecoins stopped being useful.

The point is that the market is no longer small enough to treat stablecoins as one clean crypto variable.

A larger stablecoin market can reflect more “liquidity” in the broad sense. It does not automatically translate into stronger buy pressure for Bitcoin. The desk question shifts from “How much supply exists?” to “Where is the supply going?”

If stablecoins move onto exchanges and spot volume follows, that still can line up with trading demand. If growth happens away from trading venues, stablecoin supply can represent payment rails, business settlement, treasury use, or remittance flows. Those are real adoption signals. They are not the same as capital rotating into spot markets.

Forecasts that point to infrastructure, not just parking

Citi also raised its 2030 stablecoin issuance forecast to $1.9 trillion in its base case and $4 trillion in a bull case, according to the same Benzinga piece.

Big issuance forecasts matter because they reinforce the story that stablecoins are evolving into financial infrastructure. Stablecoin supply can grow without the market receiving an equivalent burst of immediate exchange liquidity.

In the provided source text, Dinis Guarda, a cryptocurrency expert quoted via the Champions Speakers Agency, puts it bluntly. “Stablecoins are not moving closer to mainstream — they are already there.”

Stablecoins are not moving closer to mainstream — they are already there.

That framing matters for traders because mainstream usage changes stablecoin behavior. Money can circulate through business and cross-border rails. It can settle invoices. It can support payroll-like dollar access in places with limited banking throughput. None of that guarantees a switch into BTC the moment supply rises.

So what should be watched instead

Benzinga’s core argument is narrow and practical. Stablecoin supply alone no longer tells the story.

The more useful lens is where coins are moving, who is using them, and whether they are moving closer to trading venues.

That distinction also helps explain why a stablecoin market can expand while the market’s “buy signal” effect fades. Trading liquidity still matters. But stablecoins can be liquidity for payments and settlement as much as liquidity for orders on an exchange.

For risk-conscious readers, the takeaway is simple. Treat stablecoin assets as tools with multiple use cases. Supply growth can support markets without necessarily generating a directional impulse for any specific crypto asset.

The policy and market deadline angle

Regulation talk usually arrives late to the party. Stablecoins are already big enough that how they are classified and constrained becomes part of the plumbing story. As stablecoin market cap rises, the question for policymakers and market participants will increasingly center on use restrictions, reporting expectations and where compliance friction lands.

The trading lesson does not require a new indicator. It requires a better question. If stablecoin growth reflects payments, remittances, settlement and dollar access, then supply is not the same as buying pressure.

In the world Benzinga describes, the “more stablecoins” trade is harder to justify as a universal rule. The market is bigger, and the money has more destinations.
