365.bank ČSOB Slovakia Merger Creates a 1.4 Million-Client Lender

On 1 November 2026, two Slovak retail banks owned by the same Belgian parent became one. The 365.bank ČSOB Slovakia merger consolidated KBC Group’s two local franchises into a single institution expected to serve roughly 1.4 million clients, placing it second in Slovakia by customer count.

This article summarises the publicly announced event using details from KBC’s own newsroom and corroborating coverage, and places it in the context of gf6.com’s worldwide directory of bank branches and ATMs. We focus on what was officially stated and avoid speculation about figures that have not been disclosed. Understanding the 365.bank ČSOB Slovakia merger in full requires looking at these details closely.

The finding — what was announced — 365.bank ČSOB Slovakia merger

According to KBC Group, 365.bank legally merged into its sister institution ČSOB Slovakia on 1 November 2026, with all activities transferring to ČSOB and 365.bank ceasing to exist as a separate legal entity. The event was reported by multiple outlets, including KBC Group Newsroom, Webull and World Today Journal.

The core disclosed facts are summarised below:

What it means

The legal merger is the formal step that turns two separately licensed Slovak franchises under the same owner into one bank. On paper, 365.bank no longer exists as its own entity from 1 November 2026 — its activities now sit inside ČSOB Slovakia. In practice, customers continue to see both the ČSOB and 365.bank brands in the market until the planned system migration in 2027. These figures put the 365.bank ČSOB Slovakia merger into clearer perspective.

By customer count, the combined bank is expected to be the second-largest in Slovakia, serving around 1.4 million clients. KBC also projects the merged entity will hold roughly 20% of the Slovak market for net retail loans and mortgages — a notable share for a single lender in a mid-sized European retail market. This context matters for anyone following the 365.bank ČSOB Slovakia merger.

“The legal merger of ČSOB and 365.bank marks the next chapter in that journey,” said Johan Thijs, CEO of KBC Group, in the group’s newsroom statement. Beyond that attributed line, this is widely seen as part of a broader pattern of Western European banking groups rationalising separately acquired Central European franchises into unified national platforms. It is a central thread in the wider 365.bank ČSOB Slovakia merger.

What the data does not tell us is how the combined branch and ATM footprint for banks in Slovakia will look once the migration completes in 2027. Decisions about overlapping branches, ATM networks and product ranges typically follow such mergers, but the specific scope has not been quantified in the materials cited here.

Methodology

This article summarises a publicly announced corporate event using statements from KBC Group’s newsroom and corroborating coverage. No figures beyond those explicitly disclosed in the cited sources have been added. gf6.com maintains a worldwide directory of around 445,000 bank branches and ATMs (roughly 346,000 branches and 99,000 ATMs), compiled and curated manually from public sources over four years since 2020. The directory is a large but incomplete sample of the world’s financial infrastructure, and coverage varies by country. It is not an official or government dataset. Such details shaped how the 365.bank ČSOB Slovakia merger unfolded.
