The European Central Bank has begun the biggest cleanup of its ECB banking supervision rulebook since the Single Supervisory Mechanism launched, promising lenders faster decisions and far less paperwork.
Supervisors reviewed roughly 130 guides, reports, letters and methodologies, then scrapped around 40 of them as outdated or duplicative. The ECB set out the overhaul in a 26 June statement and a follow-up blog on 6 July.
Speed sits at the heart of the reform. For standard capital transactions, the ECB now clears eligible cases in about a week, a process that once dragged on for months. In the first four months of 2026, supervisors judged roughly 80% of applications to reduce own funds eligible for that fast track and waved them through in under a week.
On-site inspections have tightened too. The ECB completed them about 10% faster on average during 2026, freeing supervisors to spend more time on the banks that actually carry higher risk.
The bank is also rewriting its core guidance. It plans to publish a revised Guide to licence applications in the third quarter of 2026, an updated guide on risk data aggregation and reporting in the fourth quarter, and a refreshed guide to on-site inspections and internal model investigations by the end of the year.
Supervisory board members frame the drive as a way to cut friction without lowering standards. Leaner processes, they argue, let banks plan capital moves with more certainty while keeping the resilience that the post-2014 framework was built to protect.
The timing matters. ECB supervisors have complained that market fragmentation, not capital, is the real constraint on European banks trying to operate across borders, and a simpler rulebook chips away at that barrier.
For Europe’s lenders, the practical payoff is predictability. A one-week answer on a capital step lets treasurers act on market windows instead of waiting out a bureaucratic queue, a point banks have pressed on Frankfurt for years.
Critics will watch whether faster sign-offs quietly thin scrutiny. The ECB insists the opposite: by clearing routine files quickly, it can aim its sharpest tools at the weaker balance sheets that pose real danger. The supervision arm says the reform agenda will run through the rest of 2026.
