SoFi's tokenized deposit pays 4.40%. The GENIUS Act is why

SoFi Bank started paying interest on a token on Thursday. SoFi Earn, ticker SOFIE, launched October 22 as what the company calls the first national bank-issued tokenized deposit sold to consumers: each SOFIE is $1 held on deposit at SoFi Bank, earning 4.40% APY, FDIC-insured up to applicable limits.

The 4.40% is the whole story. Under the GENIUS Act, a stablecoin issuer cannot pay holders interest or yield of any kind solely for holding the coin. SoFi runs a stablecoin, SoFiUSD, and it pays nothing, because it can't. SOFIE is the same bank balance in a different wrapper, and this wrapper can pay. The day before launch, the OCC issued its final GENIUS Act rule, and its preamble said the quiet part: asked to confirm the yield prohibition doesn't capture deposits, the agency confirmed it does not, "including deposits in tokenized form" (the rule text hit the Federal Register on October 23).

The mechanics are simple enough to fit in one screen. A member parks money in a SOFIE deposit account, accessible through their SoFi Crypto account, and earns the APY while waiting. When they want to actually use the money, they convert SOFIE 1:1 into SoFiUSD and either buy crypto in the app or send dollars to an external wallet over blockchain rails, 24/7. Deposit for earning, stablecoin for moving, one toggle between them.

The pitch: your stablecoins are dead money

SoFi's launch materials lead with a Federal Reserve estimate that roughly $64 billion, 21.2% of the stablecoin market, sits idle in rarely used, forgotten or inactive wallets. CEO Anthony Noto put the product philosophy bluntly in his interview with Fortune: "I say to my team 'money doesn't sleep' doesn't mean it just moves 24/7, but it also needs to be making money 24/7."

The addressable customer, in Noto's telling, is the crypto user who parks cash in stablecoins between trades and earns nothing on it. He called crypto companies "low hanging fruit" and told Fortune they'll be able to pay Mastercard and other service providers that also hold accounts at SoFi Bank. Fortune pushed back on the logic, asking why anyone needs SOFIE when SoFi's own savings account already pays a competitive rate and its stablecoin already moves. The honest answer is that SOFIE exists to keep the yield inside the fence: money that would sit in USDC earning zero now sits at SoFi Bank earning 4.40%, and converts to crypto activity on SoFi's own app.

What SOFIE can't do

Tokenized deposits carry a structural limitation that stablecoin advocates never let banks forget: they only move between parties who both have a relationship with the issuing bank. Send SOFIE to someone outside SoFi's ecosystem and the transfer doesn't exist. USDC goes to any wallet on earth. SoFi's answer is the conversion step: leave the deposit form the moment you need to reach someone outside, take the yield-free stablecoin leg, accept the tradeoff.

That makes SOFIE less a challenger to stablecoins than a yield vault with stablecoin egress. Which may be exactly what a bank is allowed to build, and enough on its own.

Fifth launch in a year, all pointed at the same charter

SoFi Earn is the company's fifth crypto product in under twelve months. It returned to consumer crypto trading in late 2025 after an earlier exit, per Decrypt the first nationally chartered US bank to offer that to consumers, now with 40-plus tokens tradable. It followed with SoFiUSD, the first stablecoin issued by a US national bank, running on Ethereum and Solana and now settling SoFi's entire card program over Mastercard's network, plus business banking for digital assets and a stablecoin arrangement involving Kraken.

The Clarity Act backdrop matters here too. That market-structure bill collapsed in Congress largely over a provision that would have let companies pay interest on stablecoins, with the banking industry arguing yield-bearing stablecoins threaten financial stability. Fortune reported the launch right against that fight. SoFi's move sidesteps the whole argument: it doesn't need Congress to allow yield on stablecoins when its deposits can bear yield natively.

The read

The interesting fight in digital dollars is no longer stablecoins versus tokenized deposits as philosophies. It's inside the banks that issue both. SoFi holds a national bank charter, a stablecoin, and now a yield-bearing deposit token, and the OCC's rulemaking just drew the line that decides which of those can pay you: the deposit can, the stablecoin can't, and the difference is 4.40% a year, as of October 22. Every bank with a charter and a blockchain ambition is watching whether consumers actually toggle.

One number to hold onto: 21.2%. If even a tenth of that idle $64 billion moves into yield-bearing deposit products at any bank, the stablecoin market's center of gravity shifts without a single rule changing.
