A Bermuda-based bank with $14.4 billion in assets is acquiring a Barbados-based bank with $14.3 billion in assets, in cash and stock, to create a $29 billion institution spanning 10 Caribbean markets. Here's what the deal actually contains, and what it changes.
On May 28, the Bank of N.T. Butterfield & Son Limited β the Bermuda-headquartered, NYSE-listed bank better known in the region simply as Butterfield β announced a definitive agreement to acquire CIBC's controlling 91.7% interest in CIBC Caribbean Bank Limited for approximately US$1.8 billion. It is, by transaction value, the largest piece of regional banking consolidation announced in recent memory, and it lands directly on top of two themes this publication has covered extensively: a liquidity-starved region where scalable deal flow is rare, and a banking sector still adjusting to a decade of correspondent-relationship de-risking. This report breaks down exactly what Butterfield is buying, what it's paying, and what changes for the roughly half a million customers CIBC Caribbean currently serves.
Under the terms of the agreement β unanimously approved by Butterfield's board β Butterfield will acquire CIBC Investments (Cayman) Limited, the holding company through which CIBC holds its 91.7% interest in CIBC Caribbean. CIBC Caribbean itself is a relationship bank headquartered in Barbados with a long regional history, operating in 10 countries across the Caribbean through approximately 2,700 employees and 41 branches and offices, alongside a representative office in Hong Kong that supports business development. It serves more than 526,000 customers. Butterfield, for its part, brings its own established franchise across Bermuda, the Cayman Islands, the Bahamas, the Channel Islands (Guernsey and Jersey), the United Kingdom, Switzerland, and Singapore β a footprint concentrated in international financial centres rather than the wider Caribbean basin CIBC Caribbean serves.
The $1.8 billion headline figure breaks down into two distinct components. Butterfield is paying US$1,091 million in cash and US$703 million in its own shares, valued off its 10-day volume-weighted average price of $55.66 as of May 27, for an aggregate consideration of US$1,794 million β a structure that leaves CIBC, the seller, holding a meaningful equity stake in the combined bank going forward rather than exiting the relationship entirely.
Why the stock component matters: Because part of the consideration is paid in Butterfield shares rather than cash, CIBC will retain an equity interest in the combined bank going forward β reported at roughly 22% of Butterfield post-close. That gives CIBC a continued economic stake in the merged entity's performance rather than a clean exit, which is a meaningfully different structure from an all-cash sale.
Individually, Butterfield and CIBC Caribbean are almost identically sized β $14.4 billion and $14.3 billion in total assets, respectively, as of their most recent reporting periods. Combined, the roughly $29 billion institution immediately becomes one of the largest banking groups operating in the Caribbean and adjacent international financial centres, vaulting past Jamaica's NCB Financial Group and landing just ahead of Scotiabank's Caribbean operations β the two institutions that, alongside Butterfield and CIBC Caribbean themselves, have anchored regional banking competition for years.
The scale headline obscures a sharper, more local story. Butterfield's own 2025 annual report identified CIBC FirstCaribbean β CIBC Caribbean's operating brand in several markets β as one of its two most significant competitors in the Cayman Islands, alongside Scotiabank. The Cayman Islands is a high-income market central to Butterfield's existing wealth-management and private-banking franchise, and this transaction removes one of the only two banks Butterfield itself considered a serious rival there. That is a materially different story from "two regional banks combining for scale" β it is, in at least one specific and lucrative jurisdiction, one bank acquiring its own direct competitor.
"This deal combines two storied and complementary banks, with significant local scale advantages and time-honoured customer relationships in their respective core jurisdictions."

The transaction is not expected to close quickly. Regulatory approval is required across multiple jurisdictions given CIBC Caribbean's ten-country footprint, and the Bermuda Monetary Authority will continue to serve as the consolidated group supervisor for the combined entity. Butterfield has targeted a close date of March 31, 2027 β roughly ten months after the initial announcement β reflecting the complexity of coordinating approvals across that many regulators simultaneously.
An echo of 2018: CIBC previously attempted to list FirstCaribbean directly on US stock markets in 2018; that effort did not proceed. Butterfield's current plan β secondary listings on regional exchanges rather than a US listing β is a more modest ambition, but would still be one of the more significant additions to the Jamaica, Barbados, Bahamas, or Trinidad exchanges in recent years if it proceeds as described.
For CIBC Caribbean's existing customers, both companies have publicly committed to continuity rather than disruption: the regional headquarters stays in Barbados, the existing operational footprint across the ten countries is maintained, and both banks have pointed to expanded corporate, personal, and wealth-management services, enhanced cross-border payment capabilities, and continued investment in digital banking technology as the customer-facing upside of the combination. CIBC Caribbean CEO Mark St. Hill framed the deal as uniting "two organisations with shared values and a common focus on relationship banking," while CIBC's own CEO, Harry Culham, cited the "strategic benefits" of the transaction for the parent group.
The harder question β one this publication will keep tracking as the deal moves through regulatory review β is what happens to competitive intensity and correspondent-banking capacity in the smaller markets CIBC Caribbean serves once a rival the size of Scotiabank is folded into Butterfield's own franchise. A larger, better-capitalised, NYSE-listed banking group may be better positioned to maintain international correspondent relationships than a mid-sized regional bank operating alone β a genuine potential benefit given the de-risking pressures this publication has covered extensively. Whether customers in the region's smaller markets see that benefit, or instead see fewer competing options for the same services, will depend heavily on decisions regulators in all ten jurisdictions have not yet made public.
