Stablecoin News, October 2026: What Changed For Holders This Month

Stablecoins had a busy few weeks in September and October 2026. A phone maker said it will put USDC in its wallet, a bank started settling card payments in its own coin, a group of payment giants launched a new dollar token, and Tether’s power to freeze and destroy coins came back into the news. Meanwhile, the argument over who may pay stablecoin rewards moved from Congress to the regulators.

The short version for holders: more firms now issue or carry dollar tokens, and most new designs share the reserve income with businesses, not with you. Each section gives the date, what happened, why it matters and the open question. Facts are as of 15 October 2026.

Why are banks and crypto firms fighting over stablecoin yield?

Because the law leaves a gap. The GENIUS Act, enacted 18 July 2025, bars issuers from paying holders interest or yield solely for holding. It does not explicitly stop exchanges paying rewards, and Circle shares part of its reserve interest with Coinbase.

Bank groups say rewards could pull deposits away from lending; the ICBA estimates $850 billion less community bank lending, which is the group’s own estimate. A May 2026 Senate deal would have barred rewards that look like deposit interest while allowing activity-based rewards, CoinDesk reported. That deal rode on the CLARITY Act, which failed a Senate vote on 15 September 2026.

Why it matters: exchange rewards continue for now, but the OCC’s proposal includes a presumption covering affiliates and related third parties. The Comptroller said a final rule could come by November, per The Block. Background: the GENIUS Act interest ban.

Who holds the dollars in Samsung Wallet’s USDC?

Not Samsung. On 7 October 2026, Samsung said USDC transfers will launch in Samsung Wallet starting in the last week of October for eligible US Galaxy users aged 18 and over, with ID checks. Samsung says it “is not a bank, money transmitter, or digital asset custodian”. Bastion is the custodian and Coinbase its sub-custodian through Coinbase Prime Vault, as CoinDesk and The Block also report.

The headline “82 million” is a count of compatible devices, not users. Solana and Sui provide network support; the sources do not say which does what. Users can send to external wallets with no Samsung fee and to bank accounts in 60+ countries, where fees apply.

Why it matters: it is a convenient on-ramp, but it is third-party custody. The SEC’s custody bulletin explains the trade-offs.

Open question: whether launch happens on schedule. Earlier coverage: Samsung Wallet and USDC.

When does Tether destroy USDT?

Tether’s USDT contract has owner-only functions to blacklist an address and then destroy the tokens it holds, with no undo, BlockSec explains. Tether generally freezes first and destroys when a court order authorizes seizure, according to Spark’s research, often pairing the burn with new tokens minted to a victim or court-designated wallet. In 2025, about $1.26 billion was frozen and about $698 million destroyed. Tether’s terms set out its freeze and seizure rights.

A live example: in April 2026 Tether froze about 344 million USDT linked to Iran. Families of 9/11 victims asked a New York court to order a turnover, The Block reported, and in July 2026 a federal court let them move forward, per MLex. No handover has been reported.

Why it matters: USDC can also freeze, but has no burn-and-reissue function. Knowing which switch your coin has is basic custody hygiene. See why XRP cannot be frozen but stablecoins can.

What is live on Circle’s Arc, and what is still roadmap?

Circle switched on Arc’s public mainnet on 16 September 2026, The Block reported. Fees are paid in USDC. The validator set is permissioned, with 11 named founding validators including BlackRock and Visa. Circle minted 10 billion ARC tokens but said this is “not a commitment to publicly launch ARC”. A possible move from proof of authority to proof of stake is mentioned for 2027.

Still planned: Circle says BlackRock is “expected to” deploy its BUIDL fund on Arc and DTCC will enable tokenization there, with the DTCC work not starting until the second half of 2027. Arc’s own post warns that “All Arc features may be modified, delayed, or cancelled”.

Why it matters: Arc is a company chain run by approved validators, not an open network.

Open question: whether ARC ever becomes a public token. More in Circle Arc and the XRP Ledger.

Is SoFi’s bank stablecoin FDIC insured?

No. On 22 September 2026, SoFi said stablecoin settlement is live across SoFi Bank’s debit and credit card program on Mastercard’s network, and expects more than $25 billion in annualized volume, a projection. Merchants do not need to hold stablecoins and can take settlement as cash.

SoFi’s own disclosure says SoFiUSD is not a deposit, not FDIC or SIPC insured, not bank guaranteed and may lose value. The FDIC confirms its insurance does not cover crypto assets. SoFiUSD is redeemable one for one and was fully reserved by cash at launch. The Block reported it launched on Ethereum in December 2025, with a Solana plan announced in May 2026; the card release does not name a chain.

Why it matters: “issued by a bank” and “insured like a bank deposit” are different things.

Open question: which chain carries card settlement, and whether other banks follow.

Who backs Open USD, and who gets its reserve income?

Open USD (OUSD) launched on 30 September 2026. It is issued by Bridge, owned by Stripe, and run by Open Standard, with Coinbase, Mastercard, Shopify, Stripe and Visa as founders, Forbes reported. It runs on Base, Ethereum, Solana and Tempo. Reserves are held at BlackRock, Lead Bank and BNY, with monthly attestations promised; none had been published in the sources we read as of 14 October.

The model: businesses mint and redeem without fees, and most reserve income goes to participating businesses after a small management fee, per Open Standard as reported by Bankless. Founders pledged roughly $1 billion of seed liquidity, a pledge rather than a balance.

Why it matters: for comparison, Circle’s revenue is mainly reserve income, about $2.64 billion of $2.75 billion in 2025, per its results. OUSD hands that income to distributors.

Open question: the first attestation. An attestation is a point-in-time check, not a full audit, Forvis Mazars notes.

What did U.S. Bank’s USBDC pilot on Stellar prove?

On 9 September 2026, U.S. Bank said it completed a live pilot transaction with its USBDC stablecoin on Stellar: a cross-border payment between U.S. Bank entities in North America and Europe. The pilot tested minting, payment, redemption, freezing and clawback on the bank’s own platform. The bank calls it one of the first bank-issued stablecoins on a public blockchain.

The headline says “launches”, but the body describes a pilot between the bank’s own entities. Stellar’s clawback feature lets an issuer pull tokens back, which banks want for compliance. The Stellar Development Foundation says payments settle in seconds for under a cent; those are its own claims.

Why it matters: it is a working test, not a customer product.

Open question: what backs each token beyond “U.S. dollar-backed”. Neither source mentions XLM demand.

What would USDT on Bitcoin through RGB change?

Tether co-led a $7.5 million round in Utexo in March 2026 to launch native USDT settlement on Bitcoin, The Block reported, using the RGB protocol. RGB keeps a small commitment on Bitcoin and validates transfers on the user’s side.

The interesting part is freezing. CoinDesk reports that Utexo can’t freeze RGB USDT the way Tether freezes an Ethereum address, and would instead keep a blacklist of Bitcoin outputs; Utexo’s Ihnatiuk said a blacklisted output “will just become unredeemable”. Tether’s terms still let it freeze tokens.

Why it matters: “on Bitcoin” does not mean “free of issuer control”. The control just works differently.

Open question: CoinDesk’s article gives conflicting launch timing, so as of 14 October this is planned, not live. Who keeps the blacklist, and how appeals work, are not public.

Who shares the reserve income from USDG on Arbitrum?

Partners, not holders. On 5 October 2026, the Paxos-led Global Dollar Network said Arbitrum had joined and USDG is now natively issued on Arbitrum One. The network distributes rewards from USDG reserves to partners that drive adoption, CoinDesk reported. Paxos issuers in Singapore and the EU redeem one for one, with monthly reserve reports, the network says.

A separate Arbitrum DAO proposal would put 100 million ARB toward a growth program and move some treasury assets into USDG. It was at the forum stage with no vote result on 14 October; on-chain voting is scheduled for 29 October to 12 November.

Why it matters: the same pattern as Open USD. A stablecoin’s reserves earn money, and the setup decides who gets it. None of the sources describes payments to individual holders.

Open question: the DAO vote outcome.

What does Polygon’s Open Money Stack add for TRON USDT and US payments?

Two steps in one week. On 7 and 8 October 2026, Polygon said its Open Money Stack now supports TRON, so businesses can take USDT on TRON, route it and pay out through one integration, per Polygon’s blog and CoinDesk. CoinDesk notes this “does not make TRON a bank”.

Then on 14 October, Polygon Labs completed its purchase of Coinme, adding 37 state money transmitter licenses and 11 exemptions, described as coverage across 48 states, The Block reported.

Why it matters: licenses decide who may move dollars and where. Company news is not token news; neither source mentions POL. Tether’s freeze terms still apply to USDT moving through any of it.

Open question: Polygon says the stack “is live today”, while The Block says the unified integration is in technical preview for select customers.

What to watch next

• Last week of October: Samsung Wallet’s USDC launch and its partner terms.
• By November: the OCC’s final GENIUS Act rule and how it treats exchange rewards.
• 29 October to 12 November: the Arbitrum DAO vote on USDG.
• The first Open USD reserve attestation.
• A firm date for USDT on Bitcoin.
• The New York court case over the frozen $344 million in USDT.
