Verifactu and stablecoins: 6 payments stories of the week
Possible Spanish tax agency letters over Verifactu and e-invoice mismatches, USDC settlement in LatAm and what the ECB published.
Spain's tax agency (Hacienda) could send information requests to self-employed workers whose Verifactu records do not match their e-invoices, according to Pymes y Autónomos. ACI Worldwide and Circle are exploring how to bring stablecoin settlement into existing banking infrastructure. The week also brings an open banking debate, a subletting case and two European Central Bank publications.

ACI Worldwide and Circle: stablecoin settlement on existing banking rails
ACI Worldwide and Circle, which issues USDC through regulated entities, have announced a collaboration to show how stablecoin settlement can be added to the banking and payment infrastructure already in place. According to Finextra, which carries the ACI and Circle announcement, the geographical focus is Latin America. The summary gives no details on participating banks, volumes or timelines.
Why it matters: for businesses selling to Latin American customers from Europe, more direct settlement could affect payout times and costs, although for now this is a demonstration. Background is in our key points on cards and stablecoins.
Verifactu and e-invoicing: possible tax agency letters to the self-employed
Pymes y Autónomos expects Spain's tax agency to launch, in the medium term, a new round of information requests comparing Verifactu records with those of mandatory e-invoicing. In its article on the tax letters, the outlet explains that running both systems side by side makes discrepancies more likely, especially when an invoice is changed after issue. That means requests and extra costs for small businesses.
Why it matters: anyone issuing invoices automatically after each payment or refund should check that corrections follow the same path in both systems. This is a press reading, not an official instruction; it is worth checking with a tax adviser.
Open banking according to NatWest: a commercial model is missing
Simon Eacott of NatWest argued at Sibos 2026 that open banking needs a sustainable commercial model to scale account-to-account (A2A) payments and AI-based services. Finextra publishes it as a Sibos video interview; the summary does not say which model he proposes or on what timescale.
Why it matters: if A2A payments gain ground, checkouts could add alternatives to cards, but their cost to merchants will depend on how that model is settled.
Subletting by the room: the case of a Zaragoza investor
Rocío, an investor from Zaragoza, pays the owner of a flat around 950 euros a month and charges around 400 euros for each of its four rooms, about 1,600 euros in total, according to Pymes y Autónomos. She is left with 650 euros for utilities and other costs, as she explained in a YouTube interview with Carlos Galán covered in the report on renting by the room.
Why it matters: the link to online payments is indirect; it illustrates a recurring-income business with a thin margin, where one missed payment weighs heavily. Subletting has legal and tax implications worth reviewing with a professional.
ECB Governing Council: decisions other than interest rates
The European Central Bank published on 30 October the other Governing Council decisions, those that do not set interest rates. The material includes only the headline, with no summary, so we cannot say which topics it covers.
Why it matters: without knowing the content, its effect on payments cannot be assessed; we recommend reading the original release.
ECB Survey of Professional Forecasters: fourth quarter of 2026
The European Central Bank released on the same day the results of its forecasters survey for the fourth quarter of 2026. The material does not include the forecasts, so we do not reproduce any figures.
Why it matters: analysts' expectations are a reference for planning prices and budgets, but they should be checked at the source.
