Under the GENIUS Act, stablecoin issuers can't pay you interest. Banks can. The SoFi tokenized deposit, launched on 22 October 2026 as SoFi Earn (ticker SOFIE), sits exactly on that line: each token is $1 on deposit at SoFi Bank, earns 4.40% APY and carries FDIC insurance up to the usual limits (SoFi press release).
The moment you want to move that money on-chain, it stops being a deposit. You convert SOFIE 1:1 into SoFiUSD, SoFi's payment stablecoin, which pays nothing and isn't FDIC-insured.
This breakdown covers what SoFi actually launched, why the GENIUS Act forces a two-token design, what 4.40% is worth against Treasury bills, how SoFiUSD looks in October 2026, and who should (and shouldn't) park cash in SOFIE.
Key Takeaways
- SOFIE is a deposit token: $1 at SoFi Bank, 4.40% APY, FDIC-insured to applicable limits (SoFi).
- Converting SOFIE 1:1 into SoFiUSD ends both the interest and the deposit insurance (Decrypt).
- The GENIUS Act bars payment stablecoin issuers from paying interest, which opens room for bank deposit tokens (Reuters).
- SOFIE's 4.40% APY sits above the 4.01% 4-week Treasury bill rate of 23 October (U.S. Treasury).
- SoFiUSD supply was $350.2 million on 25 October 2026, up 8.5% in a month (DefiLlama).
What SoFi launched on 22 October
Let's start with the product facts. SoFi Technologies announced SoFi Earn on 22 October 2026 and calls it the first and only national bank-issued tokenized deposit for consumers. Members reach it through their SoFi Crypto account, and SoFi says it is the company's fifth new crypto offering in less than a year (SoFi press release).
Each SOFIE represents $1 held on deposit at SoFi Bank, N.A. The rate sheet dated 20 October 2026 lists an interest rate of 4.31368% and an APY of 4.40%, with interest accrued daily, compounded monthly and credited monthly. There's no minimum balance, and the rate is variable (SoFi disclosures).
Rollout is gradual. SoFi told The Block it expects to finish offering SOFIE to its crypto members in November (The Block, 22 October 2026). SoFi had 15.8 million members at the time of the launch (SoFi).
The pitch is aimed at a narrow habit: crypto users who park dollars between trades. CEO Anthony Noto told Reuters the primary opportunity is with "people who already participate in crypto and want that money to keep working and ready to move" (Reuters via CNA).
Why SoFi needs two tokens instead of one
Here's the problem SoFi is solving. The GENIUS Act, signed in 2025, bars stablecoin issuers from paying interest. Reuters notes that this put pressure on the old habit of parking crypto cash in interest-bearing stablecoins and opened a lane for banks to offer regulated, interest-bearing alternatives such as tokenized deposits (Reuters).
A deposit token sidesteps that ban because it isn't a stablecoin at all. It's a bank deposit, with a token as the record. The FDIC's April 2026 proposal says exactly that: deposit insurance does not depend on the technology or recordkeeping a bank uses to record its deposit liabilities (FDIC FIL, April 2026).
The same FDIC proposal goes the other way for stablecoins. Deposits held as reserves behind a payment stablecoin would not be insured to stablecoin holders on a pass-through basis, and permitted issuers would generally have to redeem within two business days (FDIC). For the wider picture on stablecoin insurance, see Are stablecoins FDIC insured?.
So SoFi splits the job. SOFIE holds and earns. SoFiUSD moves. The table below lines them up using SoFi's own disclosures.
| Feature | SOFIE (SoFi Earn) | SoFiUSD (SOFID) |
|---|---|---|
| Legal form | Deposit liability of SoFi Bank, N.A. (SoFi) | Payment stablecoin issued by SoFi Bank, N.A. (SoFi and Mastercard) |
| Yield | 4.40% APY, variable, as of 20 October 2026 (SoFi) | None. Payment stablecoin issuers can't pay interest under the GENIUS Act |
| FDIC insurance | Up to $250,000 per depositor, per bank, per ownership category (FDIC) | Not a deposit, not FDIC- or SIPC-insured |
| On-chain transfer | No. Convert to SoFiUSD first | Yes, 24/7 to supported external wallets (Decrypt) |
| Main job | Hold idle dollars and earn | Buy crypto, send on-chain, settle card transactions |

The yield math: what 4.40% is worth
At first glance, 4.40% looks like a promotional rate. It isn't far from the market. On 23 October 2026 the 4-week Treasury bill yielded 4.01% on a coupon-equivalent basis, the 13-week bill 4.14% and the 52-week bill 4.41% (U.S. Treasury daily bill rates).
That means SOFIE pays roughly what a one-year bill pays, while staying withdrawable and insured. The table shows a full year at today's rates. SoFi's APY is variable and bill yields move, so treat these as a snapshot, not a forecast.
| Balance held 1 year | SOFIE at 4.40% APY (<a href="https://investors.sofi.com/news/news-details/2026/SoFi-Launches-SoFi-Earn-SOFIE-the-First-and-Only-National-Bank-Issued-Tokenized-Deposit-for-Consumers/default.aspx">SoFi</a>) | 4-week bill rolled at 4.01% (<a href="https://home.treasury.gov/resource-center/data-chart-center/interest-rates/TextView?type=daily_treasury_bill_rates&field_tdr_date_value_month=202610">Treasury</a>) | SoFiUSD (no yield) |
|---|---|---|---|
| $5,000 | $220 | $200.50 | $0 |
| $25,000 | $1,100 | $1,002.50 | $0 |
| $250,000 | $11,000 | $10,025 | $0 |
Stablecoin Insider's calculation. The $5,000 row mirrors the example SoFi itself uses for a member saving toward a future crypto purchase (SoFi). Rates as published on 20 and 23 October 2026; APY and coupon-equivalent yields aren't perfectly comparable.
One catch is easy to miss. SOFIE isn't eligible for SoFi's Insured Deposit Program, and for FDIC purposes the balance is added to your other SoFi Bank deposits in the same ownership category. If you already hold $200,000 in SoFi Checking and Savings, only $50,000 more of SOFIE is inside the standard $250,000 cover (FDIC).
The $64 billion idle stablecoin pitch, checked
SoFi frames the launch around idle money. Its release cites Fed research estimating that about $64 billion, or 21.2% of the stablecoin market, sits in rarely used, forgotten or inactive wallets (SoFi).
The source is a Kansas City Fed Payments System Research Briefing from April 2026, and it's worth reading the method. The 21.2% idle share is an assumption, not a count: the author starts from a 2024 Forbes estimate of 30% idle and lowers it to offset the 48.8% trading share measured from DefiLlama data on a $300.5 billion market in November 2025 (Kansas City Fed).
The same briefing estimates payments at less than 1% of stablecoin use, or about $2.0 billion of supply (Kansas City Fed). That's the more useful number for SoFi. Most stablecoin dollars are parked or trading, not spending, which is exactly the balance a yield-paying deposit token wants to capture.
For scale, the stablecoin market stood at about $303.45 billion on DefiLlama on 25 October 2026 (DefiLlama). Applying the same 21.2% share gives roughly $64.3 billion, and at the 4.01% bill rate that idle pool forgoes about $2.58 billion a year. That's Stablecoin Insider's illustration, built on a modeled share.
SoFiUSD in October 2026: supply, chains and card settlement
SOFIE only works if SoFiUSD is useful on the other side of the conversion. DefiLlama tracked $350.2 million of SoFiUSD on 25 October 2026, up from $322.87 million on 25 September, an 8.5% monthly gain (DefiLlama SoFiUSD).
Solana carries most of it: $250.12 million, or 71.4% of supply, against $100.08 million on Ethereum (DefiLlama). Against the whole market, SoFiUSD is about 0.12% of stablecoin supply.
The bigger use is internal. On 22 September 2026, SoFi and Mastercard said SoFi Bank is migrating its entire $25 billion card program to stablecoin settlement with SoFiUSD, and that SoFi is in talks with large U.S. merchants about stablecoin-based settlement (SoFi and Mastercard). Stablecoin Insider's earlier coverage of the SoFiUSD launch has the background on the token itself.
Who SOFIE is for, and who it isn't
SOFIE makes sense for one kind of user: a U.S. SoFi member who keeps cash ready for crypto purchases and would otherwise leave it in a non-yielding stablecoin or an exchange balance.
It's a weaker fit in four cases:
- You want yield while the money sits on a public chain. SOFIE doesn't move on-chain; only SoFiUSD does, and SoFiUSD pays nothing.
- You already hold large SoFi deposits. SOFIE shares your FDIC limit with them and isn't swept into the Insured Deposit Program.
- You need a fixed rate. The APY is variable, and SoFi can change it at any time with no limit on amount or frequency.
- You're not a SoFi Crypto member yet. Access is rolling out to eligible crypto customers through November.
The other open question is portability. SOFIE lives inside one bank's app. A stablecoin, for all its limits, can be held in any wallet. That trade-off is the whole design, and it won't suit everyone.
What it means for banks and stablecoin issuers
SoFi isn't alone in pushing bank money on-chain. Reuters reported that in September a group of 21 financial institutions including Goldman Sachs, Bank of America, Citi and Deutsche Bank said they planned to form a company this year to issue a dollar-pegged token in the first half of 2027 (Reuters).
What SoFi adds is the consumer pairing: one deposit token for earning, one stablecoin for moving, under a single national bank charter. The OCC's final GENIUS Act rule takes effect on 18 January 2027 (see the OCC GENIUS Act final rule breakdown), and the yield line it draws is the line SOFIE was built around.
For non-bank issuers, that's the uncomfortable part. A bank can now offer a dollar token that pays 4.40% and carries deposit insurance, then swap it into a payment stablecoin at the moment of use. Exchange-based stablecoin rewards programs will be compared against that offer.
FAQ
What is the SoFi tokenized deposit?
It's SoFi Earn (SOFIE), a token that represents $1 on deposit at SoFi Bank and earns 4.40% APY with FDIC insurance up to applicable limits (SoFi).
Is SOFIE a stablecoin?
No. SoFi's disclosures describe SOFIE as a deposit liability and say it is not a payment stablecoin. SoFiUSD is the stablecoin (Decrypt).
Is SoFiUSD FDIC insured?
No. SoFiUSD is not a deposit and isn't covered by the FDIC or SIPC. Only the SOFIE balance is insured, up to $250,000 per depositor per ownership category (FDIC).
Why doesn't SoFiUSD pay interest?
Because the GENIUS Act bars payment stablecoin issuers from paying interest. That's why SoFi pays yield on the deposit token instead (Reuters).
How do I move SOFIE on-chain?
You convert SOFIE 1:1 into SoFiUSD inside the SoFi app, then send SoFiUSD to a supported external wallet. The converted amount stops earning and loses deposit insurance.
When will SOFIE be available to all SoFi Crypto members?
SoFi expects to finish the rollout to its crypto members in November 2026 (The Block).
What to watch next
Three dates matter. SoFi reports third-quarter results at about 7 a.m. Eastern on Tuesday 27 October 2026 (SoFi IR), the SOFIE rollout should finish in November, and the GENIUS Act regime goes live on 18 January 2027.
If you hold dollars for crypto purchases, the useful move on Monday is simple: compare the rate on your parked balance with SOFIE's posted APY and the current bill rate, and check how much of your FDIC limit is already used. Then decide whether the conversion step is worth it.
