"Financial institutions and fintechs today struggle to offer both fiat and stablecoin accounts, creating the risk of customer deposits moving to competing stablecoin accounts."

- Michael Miebach, CEO of Mastercard · Q3 earnings call, October 29, 2026

Hey, it's Marc.

Welcome to our Weekly Edition of the 51 Insights digital asset newsletter.

On Monday I wrote about HSBC's RedCoin, a stablecoin that pays 0% and can't leave HSBC's own apps. By Monday, about HK$81 million of RedCoin was in circulation, roughly US$10 million.

Here's what else matters this week:

Let's unpack.

On the podcast

Former CFTC chair Chris Giancarlo thinks the digital euro will be a surveillance tool. He has a warning for stablecoin fans too: "Stablecoins provide no better privacy protection than a Chinese-style or a European-style CBDC."

Also out: Jeff Booth on why the debt can't be repaid.

01 / MARKET STRUCTURE · PRO ANALYSIS

Wall Street tokenizes on its own terms

What's going on here?

On Wednesday DTCC switched on its tokenization service. Its depository holds $114 trillion of securities. It can now turn eligible holdings into tokens that keep the same ownership rights and investor protections, on Canton and DTCC's own private network. Twenty firms signed up, including JPMorgan, Citi, Morgan Stanley and Citadel Securities.

The same week, objections to OKXICE, the OKX and ICE venture for third-party stock tokens, reached 38. It hasn't started trading.

What does this mean?

Last week I wrote that companies would say yes to tokens issued inside the existing custody system. JPMorgan did exactly that: Tuesday's OKXICE notice listed it as an objector, while Wednesday's DTCC launch named it as a signed participant.

I think control explains the split. On OKXICE, someone else makes the token and picks the venue. At DTCC, the token sits on the same books as the share. Omid Malekan of Columbia calls DTCC's version "Tokens in Name Only", because they move only between approved wallets on private networks. He sees that as a weakness. For the banks that signed, it's the selling point.

Why should I care?

If you run a broker or a venue, plan for issuer consent the way you plan for custody. Many of the biggest names are saying no.

The 51 Signal: who said no

We counted every company named in OKXICE's eight public notices.

02 / CUSTODY

Google wants banks to keep the keys

What's going on here?

On Wednesday Google previewed a crypto custody tool for banks. Google Multi-Party Compute uses signing-key shares generated and held separately, for example in Google Cloud and on the bank's own servers. In Google's example, two of three must sign. Google said that Alphabet already uses it for its own crypto. It's in private preview, with a commercial launch planned for early 2027. Private-key compromises accounted for 43.8% of crypto stolen in 2024, according to Chainalysis.

What does this mean?

The tech isn't new. Fireblocks, Dfns, Utila, Privy and others already sell this setup, often called wallet-as-a-service. The key is split into shares, nobody holds it whole, and set rules decide who can sign. What's new is the seller.

My read: banks want the custody fee without handing clients to a rival, and custody firms keep getting charters. Ripple bought custody software maker Metaco for $250 million in 2023 and got its trust bank this week. BitGo became a national trust bank last December. Google pitches itself as the neutral supplier: run custody yourself, on its tools.

NYU Stern's Austin Campbell put the stakes for crypto custody firms simply: "The bar may now be 'better than Google'."

Why should I care?

If you choose a custody vendor, ask one things: will it ever compete for your clients?

03 / BANKING

Ripple buys banks a reason to say yes

What's going on here?

On Monday Ripple's national trust bank got final OCC approval, 318 days after its conditional yes. It will manage the reserves behind RLUSD, Ripple's $2.6 billion stablecoin, and act as trustee for holders. BNY, which holds the reserves, now custodies RLUSD for clients and plans direct minting. Coinbase and Robinhood's chain now carry it. Galaxy applied for its own charter on Thursday.

What does this mean?

Ripple doesn't need a bank to issue a stablecoin. It needs one so other banks can say yes to it. A bank's risk team asks three things about any stablecoin. Who issues it? Who holds the cash? Who checks? RLUSD now answers each with a regulated name. In bank sales, that beats yield.

04 / PAYMENTS · PRO ANALYSIS

The card networks pitch the fix

What's going on here?

Visa said on Tuesday that its stablecoin settlement run rate passed $25 billion a year, 10 times the level a year earlier. In January it was $4.6 billion. On Thursday, Mastercard's CEO named the deposit risk in the quote above and pitched its new Global Money Platform. It lets banks and fintechs offer accounts that hold both dollars and stablecoins. "I have really no conversation with a bank CEO where this topic doesn't come up," he said.

Meanwhile, Robinhood's crypto revenue fell 55% to $120 million. PayPal's call never mentioned PYUSD. Asked about lower crypto take rates, its CFO pointed to Robinhood Earn, its stablecoin product, now above $500 million: "we monetize it less than the normal platform." Stablecoin balances keep customers but earn the platform less.

What does this mean?

Mastercard sells to banks. So it names the fear and sells the cure in the same breath. I think that's the smart play. A bank that offers both accounts has a shot at keeping the balance.

Why should I care?

If you run a bank, both card networks now pitch you stablecoin tools. Judge them by one test: do they keep the deposit at your bank?
