Stablecoin yield vs savings account interest: sources, protection, taxes and risks

A savings account and a stablecoin can both hold dollars, but only one of them pays you for it by design. Bank interest comes from the bank, with federal deposit insurance behind the balance. Stablecoin yield, where it exists at all, comes from someone else: a crypto platform sharing revenue, a borrower paying to use your coins, or a DeFi protocol. This comparison traces each source of that yield, explains what the GENIUS Act changes, sets the numbers against savings and Treasury bills, and separates the risk of the coin from the risk of the company holding it.

Where does stablecoin yield come from?

Not from the coin itself: issuers keep the interest their reserves earn, so any yield a holder receives is paid by a platform, a borrower or a protocol.

An issuer sells coins for dollars and invests those dollars in reserves. Circle, which issues USDC, earned $2.64 billion of reserve income in 2025, at a reserve return rate of 4.1% against 5.0% in 2024, according to its annual report. At year-end, about 88% of USDC reserves sat in the Circle Reserve Fund, a BlackRock-managed government fund of the kind described in how money market funds work. Holders of the coin received none of that income directly. It reaches them, if at all, by one of three routes:

• Platform rewards. Exchanges and apps that hold coins for customers may pay rewards on balances. Circle's distribution and transaction costs were $1.66 billion in 2025, about 63% of its reserve income, and it said payments to Coinbase rose $438.4 million on higher reserve income and larger balances held on that platform. A platform can pass some of its share on, keep it, or change the terms.
• Lending. Centralized lenders and DeFi protocols lend coins to borrowers, often traders using leverage, and pay depositors part of the interest. The rate floats with demand, and the depositor carries the credit risk. In February 2022 BlockFi agreed to pay $100 million, $50 million to the SEC and $50 million to 32 states, after the SEC found its crypto interest accounts were securities sold without registration.
• DeFi protocols. Smart-contract lending markets and liquidity pools pay depositors from borrower interest and trading fees, and the return depends on code, collateral and price feeds working as designed; what is DeFi explains the mechanics.

Tokenized Treasury funds are a different product: securities that pass through interest on bills they own, covered in our post on on-chain US T-bills. An older post on our blog, ways to earn interest on USDC, surveys common methods from lending to exchange earn programs; weigh each against the risks below.

What does the GENIUS Act say about stablecoin interest?

It bans permitted issuers from paying holders any interest or yield for simply holding, using or keeping a payment stablecoin, starting when the law takes effect.

The law's timeline: Signed July 18, 2025 (Public Law 119-27); takes effect January 18, 2027. Section 4(a)(11) says no permitted or foreign issuer may pay "any form of interest or yield (whether in cash, tokens, or other consideration) solely in connection with the holding, use, or retention" of the coin. The same law sets the reserve rule: at least 1:1 reserves in cash or Federal Reserve balances, deposits at insured banks and credit unions, Treasuries with 93 days or less to maturity, overnight repos and reverse repos backed by Treasuries, government money market funds that hold only those assets, other liquid federal government assets a regulator approves, and tokenized versions of the non-repo assets. So the reserve income belongs to the issuer, which may share it with business partners but may not pay it to holders for holding.

The ban names issuers, not platforms, and that gap is where the argument now sits. The OCC published its final rule on October 23, 2026. Its proposal would have presumed that yield paid through an issuer's affiliates or related third parties broke the ban; the final rule drops that presumption but keeps the agency's authority to act against evasion. It treats payments made by an issuer's agent on the issuer's behalf as covered, offers no safe harbor for small payments, and declines to exempt reward programs that existed before the law. Each arrangement will be judged on its facts.

Congress may revisit the question. The CLARITY Act, a broader crypto market-structure bill, passed the House in July 2025, and Senate drafts would limit rewards for passive holding, but as of November 1, 2026 it had not become law. Stablecoin regulation and the GENIUS Act covers the rest of the framework.

How do stablecoin yields compare with savings accounts and T-bills?

Bank and Treasury yields are set by the institution or the market and come with federal backing; stablecoin rewards are set by each platform and have none.

A coin that earns nothing still loses ground: consumer prices rose 3.74% in the year to September 2026, so an idle dollar lost about 3.6% of its buying power, as real returns and inflation explains. Bank-side mechanics are in how high-yield savings accounts work, the bank-versus-bill trade-off in T-bills vs high-yield savings, and the Treasury bill calculator prices a bill at any rate.

Which stablecoins are largest, and how are they backed?

The table below lists the five largest dollar stablecoins by supply, with each coin's recent change, price and type of backing.

Read the backing column first. Fiat-backed coins hold cash and short-term government debt, and under the GENIUS Act a permitted issuer's reserves must be of that kind, at least one for one. Other designs rely on crypto collateral or trading strategies and carry different risks. A price that stays away from $1.00 signals a depeg: USDC traded below its peg in March 2023 after Circle's transfers of more than $3 billion out of Silicon Valley Bank failed to settle before the bank was placed into receivership. Our stablecoin data page tracks the major coins, USDC vs USDT compares the two best-known fiat-backed designs, and the stablecoin depeg history study covers past breaks.

Is a stablecoin balance FDIC insured?

No: FDIC insurance covers deposits at insured banks, and the GENIUS Act states that payment stablecoins are not federally insured and makes claiming otherwise unlawful.

A savings account, by contrast, is covered up to $250,000 per depositor, per insured bank, per ownership category, as FDIC insurance explained sets out. The coins are not deposits, even when part of the reserves sits in a bank, so that protection does not pass to holders. SIPC is no help either: its definition of a protected security expressly excludes stablecoins, so a broker's failure leaves coin holders outside its coverage. FDIC vs SIPC explains what each system does cover.

What the law offers instead is priority. If a permitted issuer fails, holders' claims on the reserves come ahead of other creditors. That protects the value of the coin, but it does nothing for coins lost when a platform holding them on your behalf fails.

What is the difference between issuer risk and platform risk?

Issuer risk is the chance the coin itself fails to hold $1; platform risk is the chance the company holding your coins fails, freezes or changes the deal.

Issuer risk lives in the reserves and the redemption process: a bank holding reserves can fail, assets can be hard to sell in a hurry, and operations or legal problems can delay redemptions. The GENIUS Act's reserve rules and monthly reserve reports reduce this risk from 2027, but the 2023 USDC episode shows how quickly a doubt about reserves becomes a market price below $1.

Platform risk starts when you hand the coins over. A rewards platform or lender may lend them on, mix them with its own assets, change the reward rate or halt withdrawals, and in a bankruptcy you are a creditor with a claim. DeFi swaps the company for code, where bugs, faulty price feeds and forced liquidations do the damage. Crypto lending risks and how safe crypto is on an exchange cover what to ask.

The two stack. A dollar earning rewards on a lending platform comes back only if the coin holds its peg, the platform stays solvent and the borrowers repay.

How are stablecoin rewards taxed?

The IRS treats rewards as taxable income valued in dollars when you receive them, and selling, swapping or spending the coins is a separate taxable disposal.

Because a stablecoin is meant to stay near $1, gains and losses on sales are usually tiny, but they still count. Brokers report sales on Form 1099-DA under a phased schedule: Gross proceeds for sales from January 1, 2025; cost basis for covered assets bought from January 1, 2026 in a custodial account. For qualifying stablecoins, brokers may use an optional method that skips reporting for a customer whose sales total $10,000 or less in a year and reports larger totals in aggregate; the sales are taxable either way. Our Form 1099-DA guide explains the form.

Timing can hurt. In Chief Counsel Advice 202444009, on rewards frozen by bankrupt digital asset platforms, the IRS concluded that rewards credited to an account before withdrawals were frozen were income when credited. Bank interest is simpler: it arrives on Form 1099-INT and is taxed as ordinary income, and Treasury bill interest is exempt from state and local income tax, as are T-bills taxable explains. Tax rules change, so a tax professional can confirm how they apply to you.

What are the risks of earning yield on stablecoins?

The yield is payment for taking several risks at once: the coin's peg, the platform's solvency, borrowers' repayment, smart-contract code and changing rules.

• No deposit insurance or SIPC cover. A failed platform leaves you as a claimant, not an insured depositor.
• Depegs. Even fiat-backed coins can trade below $1 when reserves look stuck, as USDC did in 2023; the stablecoin depeg glossary entry defines the term.
• Platform failure and freezes. Lending and rewards platforms can halt withdrawals, and regulators penalized BlockFi in 2022 over interest accounts sold without registration.
• Variable rates with no promise behind them. Rewards are set at a platform's discretion and can be cut or ended at any time.
• Smart-contract risk in DeFi. Code bugs, bad price feeds and liquidations can drain deposits; see smart contract in our glossary.
• Changing rules. The GENIUS Act takes effect January 18, 2027, platform rewards are being judged case by case, and Congress may act again.
• Tax and inflation drag. A 4% taxable reward is 3.04% after a 24% tax, below the 3.74% inflation rate of the year to September 2026.

For how these compare with the risks of deposits, bonds and stocks, see types of investment risk and the crypto hub.

What should you check before accepting a stablecoin reward?

Ask who pays the reward and from what income, what happens to your coins meanwhile, and how quickly you can turn them back into dollars.

If the aim is simply to hold dollars on-chain for payments or transfers rather than to earn a reward, the issuer's reserves and redemption terms matter more than any rate.
