190: Western Union ships a stablecoin card
Mastercard closed BVNK, Western Union shipped a stablecoin card, Visa opened stablecoin payouts, and Circle's numbers explain why: volume is exploding while the float lags far behind.
Hey, it’s Marc,
On the podcast this week, BCG’s global banking lead Christian Schmid gave me the line that ended up explaining the whole week:
“Waiting isn’t a strategy.”
Nobody waited this week. Mastercard closed its $1.5 billion BVNK acquisition on Monday, with up to $300 million more tied to an earnout. Western Union shipped a stablecoin card on Tuesday. Visa switched on stablecoin payouts for Visa Direct clients on Wednesday, on a network reaching 18 billion endpoints. And Cloudflare gave AI agents their own stablecoin wallets.
Last week we showed how the banks took the settlement layer with tokenized bank money.
This week the stablecoin side answered at the front door: the card, the app, the phone, the agent.
Circle’s earnings, out Wednesday, explain the rush. USDC moved $14.8 trillion on-chain last quarter, up 151% in a year. But the float, the pile of dollars Circle earns interest on, averaged just 25% growth, and the quarter-end pile was smaller than three months earlier. The stock fell about 4% anyway. The money is becoming a rail, and rails pay whoever owns the customer, not whoever holds still.
What to expect now: more incumbents buying the conversion layer, and stablecoin economics splitting in two: float income for issuers, transaction income for whoever owns the front door.
Below we unpack: the week’s deals, where the Clarity Act endgame stands, and why Circle’s chart matters more than its earnings.
Signals at a glance:
Circle moved $14.8 trillion and the stock fell anyway
Mastercard and Visa moved on the stablecoin conversion layer
Western Union shipped a stablecoin card
Wells Fargo tokenized the deposit
Tether halved its safety buffer while making $1.5 billion
And 10+ more signals below.

📍 Clarity Act: State of Play
The last pre-recess window. Majority Leader Thune said Sunday a vote would happen before the August recess. As of Wednesday, no cloture motion had been filed. Still open: illicit-finance provisions and the ethics language on senior officials profiting from crypto. Senator Lummis told Fox Business: “I don’t think we’ll be leaving on Friday. I think we’ll go into the weekend.” If it slips, the next plausible window is after the elections. The industry is pushing hard; Chris Dixon’s case for the bill argues the GENIUS Act showed that clear rules can draw investment.

Circle’s quarter-end float fell
What happened: Circle reported Q2 results on Wednesday: total revenue and reserve income of $701 million, up 7% year over year but slightly under Street estimates, with net income of $48 million. USDC ended the quarter at $73.3 billion in circulation, down about 5% from the prior quarter, while average circulation rose 25% year over year. On-chain transaction volume hit $14.8 trillion, up 151%. Circle nearly doubled its 2026 “other revenue” guidance to $310-330 million and confirmed its Arc blockchain goes to mainnet on September 16, with validators including BlackRock, DTCC, Visa, Mastercard, ICE, Standard Chartered, MoneyGram and Sumitomo. The stock closed down about 4% at $63.25.
“We have built the platform for the internet financial system – for traditional and digital finance, real-world assets, and the institutions that move the world’s capital.”
Jeremy Allaire, CEO of Circle, in the results release
51 View: The bull case says USDC is becoming the internet’s settlement rail and Arc gives Circle a way to charge for the flow. The bear case says Circle is a money-market fund whose assets just stalled, dressed up as a network. The September 16 mainnet launch is Circle reaching for network economics on top of its float business. Look at who signed up to validate it: the same card networks and custodians that spent this week wiring into distribution. They would all rather own a seat on the rail than rent one.

The card networks moved on the conversion layer
What happened: Mastercard completed its acquisition of BVNK on Monday. It paid $1.5 billion, plus up to $300 million in an earnout. BVNK moves roughly $30 billion a year in stablecoin payments across 130 markets, with 25+ licenses. Its clients include Worldpay, Deel, Rapyd and Flywire. Two days later, Visa and zerohash switched on stablecoin prefunding and payouts for eligible Visa Direct clients. That rail reaches more than 18 billion cards, accounts and wallets in 195+ countries.
“...stablecoins are increasingly addressing real-world needs in areas like cross-border B2B payments, remittances, payouts, settlement and treasury flows.”
Jorn Lambert, Chief Product Officer at Mastercard, in the closing announcement
51 View: A card network cares less about whose dollar moves than that it moves through them. Mastercard is the first big listed network to buy stablecoin infrastructure outright rather than partner into it. The price tells you the urgency. The conversion layer now carries billion-dollar price tags because it’s one of the few layers most users still can’t route around. Somewhere, crypto dollars have to become spendable ones.
Western Union turned the remittance into a stablecoin
What happened: Western Union launched Stablecard on Tuesday with card-infrastructure firm Rain. It’s live in 37 markets, with a target of 60 by year end. The app receives Western Union transfers directly into USDPT, the company’s dollar stablecoin issued by Anchorage Digital Bank on Solana. A linked Visa card spends it at 175 million merchant locations, with Apple Pay and Google Pay support. No credit check, no minimum balance. Fireblocks provides the wallet infrastructure.
51 View: Look at what Western Union kept and what it gave away. It kept the customer, the brand and the app. It handed the money to a federally chartered crypto bank, the settlement to Solana, and the spending to Visa. Everyone said stablecoins would kill this company. Instead, the 175-year-old incumbent used them to ship the product stablecoins were always supposed to be: a dollar account for people without a bank. A remittance that used to end as a cash pickup can now end as a dollar balance with a Visa card attached. Watch the receive side. Western Union moves roughly $100 billion a year. If even a small share starts parking in USDPT, Western Union’s corridors start doubling as stablecoin distribution.
Wells Fargo tokenized the deposit
What happened: Wells Fargo announced tokenized deposits for corporate and commercial clients on Tuesday. Money moves 24/7/365, inside the regulated, insured banking system. Rollout starts this fall with a limited US dollar to British pound corridor, then expands through 2027. Wells is the last of the big four US banks to commit, after JPMorgan’s Kinexys, Citi and Bank of America. The shared bank deposit-token network is still planned for 2027.
“Tokenized deposits will enable Wells Fargo’s corporate and commercial clients to move money between accounts and across borders with greater ease and increased speed and builds on the strength of our established banking infrastructure.”
Mike Santomassimo, CFO of Wells Fargo, in the announcement
51 View: Last week we argued banks are tokenizing deposits to defend the balance sheet. Wells Fargo completes the set. All four US mega-banks are now in. The design choice is the real signal. Wells is folding tokenized deposits into its existing payment services rather than launching a separate crypto product: no new app, no new onboarding, no “digital assets” button.
Tether made $1.5 billion and halved its cushion
What happened: Tether’s Q2 attestation, published July 31, showed $187.75 billion in assets against $183.64 billion in liabilities: a $4.11 billion excess-reserve buffer, roughly half what it was a quarter earlier. Q2 net operating profit came in around $1.5 billion, driven by about $115 billion in direct US Treasury exposure. Gold holdings rose 14 tons in the quarter to 146.2 tons, plus 98,932 bitcoin. USDT supply sat near $184.6 billion.
51 View: Tether already owns what everyone else spent this week buying: distribution, with $184 billion in float across the emerging markets where dollars are scarcest. What it traded away this quarter is margin for error. The buffer protecting USDT holders from a bad day halved, while the balance sheet tilted further into gold and bitcoin. Bitcoin tends to fall exactly when crypto stress hits, and gold carries price and liquidity risk of its own. Neither is an eligible asset for the GENIUS Act’s required one-to-one reserve pool. The next stress test will show if the balance sheet has enough room for error.

Matthew Prince, CEO of Cloudflare, in the announcement
51 View: The agent-payments stack is assembling in public, layer by layer. Two weeks ago agents got wallets inside ChatGPT. This week they got identities, spending limits and a first explicit mention in a major regulator’s planned guidelines. Notice the rail underneath all of it: stablecoins, with USDC carrying essentially all x402 volume.
