I’ve been spending time this week getting up to date on Europe from stablecoins to MiCA to AMLA. My list of official whitepapers and academic articles are below (20 of them). My summary:
Continue readingJust left a UBS webinar from the head of product for Wero and thought it would be a good time to update my July 2025 assessment of Wero as a “solution in search of a problem,”. The biggest change in Wero is the core infrastructure has transitioned from a voluntary service to a mandated utility. However, as the European Payments Initiative (EPI) attempts to scale, the project faces a fundamental conflict between political objectives and commercial unit economics.
There’s a narrative running through payments circles right now that goes something like this: stablecoins will replace card rails because they’re cheaper, faster, and programmable. Stripe makes acceptance easy. Card networks are too slow to innovate. Machine-Machine payments need programmability. GENIUS Act passed. The future is obvious.
I’ve been writing about stablecoins for over two years, from the case for stablecoin as a trust platform to the ECB’s monetary sovereignty alarm. And I keep coming back to the same conclusion: stablecoins are not a replacement for cards, but rather another rail with cards retaining their role as the layer of abstraction for multiple networks (as they do today). They will do well where cards don’t play (micropayments, B2B and uncarded markets).
Here’s why (and why that matters more than you might think).
Continue readingThe ECB published a study today warning that stablecoins could erode retail deposits across the eurozone and undermine the effectiveness of monetary policy. The finding is notable — not because it’s new, but because it’s taken this long for the institution to officially say it.
As I related last May, Italy’s Finance Minister Giancarlo Giorgetti made exactly this argument, warning that the displacement of traditional bank deposits by dollar-denominated stablecoins represented a direct threat to European monetary sovereignty. His remarks were largely dismissed at the time as political protectionism. The ECB’s study vindicates the concern. The mechanism is straightforward: if depositors move funds from bank accounts into stablecoins, banks lose the deposit base that anchors their lending capacity — and the ECB loses its primary transmission channel for monetary policy. Rate changes simply don’t land the same way when the money isn’t sitting in a regulated deposit account.
If you follow my 80+ blogs on identity, you should like this success story today. The Norwegian digital identity scheme, BankID, serves as the #2 best financial identity case study (behind India’s UIDAI) with a penetration rate of 97% across 4.7 million citizens. What could US banks learn? What are their challenges in replicating this model?
Today I’m giving the background on what BankID is.. In part 2 I’m going to interview my good friend Eric Woodward, former president of Early Warning and the creator of Zelle_ID (see youtube), at least until it was killed as the new CEO asked “what on earth does identity have to do with payments”. OMG
The FIDO Alliance is hosting a Webinar on Bank ID Norway tomorrow at 7am pacific.
Update to my 2023 blog on CCCA Complex Politics and Consequences. I’ve spent the last few weeks digging into the latest bill and I see an overstatement of potential impact that most analysts seem to have missed:
Real World Examples
Two weeks ago I penned eIDAS – EU’s Digital Siege. If you didn’t read it, the summary is that EU’s scheme is another attempt to end run BigTech and Visa/Mastercard with a set of “keys” in a digital wallet that are separate from any bank, platform or handset. While technically brilliant, trust requires either a legal mandate, or a commercial construct (and I explain why in the blog).
Today I’m going to provide a few layman’s examples of why eIDAS will not work in Financial Services (beyond acting as a signal). What is the problem the EU is working to solve? Unfortunately there is not single answer here, just like PSD2/PSD2/SEPA.. “Build it and they will come” (see blog on the EU’s Nobel Prize winner behind IFR – Jean Triole). If the core problem were “How do we prove something cryptographically across borders?”, eIDAS would already be a success.
Quick Take on WSJ – V/MA Near Deal w/ Merchants
Merchants have long expressed frustration over card costs, but it’s critical to separate signal from noise. Their issue isn’t with network fees—those average just 5 to 7 basis points and fund the global infrastructure that securely moves trillions. The real pressure point is interchange, often 250 basis points or more for premium rewards cards. That imbalance has shaped years of litigation, and now a potential reset is emerging.
I’ve never been a fan of “Pay by Bank.” It’s a solution in search of a problem, especially when compared to the efficiency of debit cards and the global reach of Visa Direct. Now, two major developments have dealt a significant blow to the already weak business case for this payment method.
Continue readingYesterday President Trump signed the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act into law, clearing the path for dollar-backed stablecoins. As I’ve argued before, the future of money is a new model of trust, and this legislation provides the regulatory certainty needed for that trust.
The GENIUS Act is a landmark piece of legislation. It establishes a dual charter system, enabling both federal and state-regulated stablecoin issuers. The key provisions are precisely what the industry needed: a mandate for 1:1 reserves with high-quality liquid assets like cash and short-term treasuries, a prohibition on reusing those reserves, and the designation of issuers as financial institutions under the Bank Secrecy Act. This isn’t just about compliance; it’s about building a foundation of trust that can be exported globally.
