Overview

The Bank of London and Montreal Limited, commonly known as BOLAM, was a historical international bank created in 1958 as a 50-50 joint venture between the Bank of London and South America and the Bank of Montreal. The Bank of London and South America, commonly abbreviated as BOLSA, was associated with Lloyds Bank and contributed an existing network of branches in northern South America and the West Indies. The Bank of Montreal supplied capital and brought Canadian banking expertise to the venture. BOLAM was headquartered in Nassau, Bahamas, giving the joint venture an operating base in an important Caribbean financial centre. The bank was established to conduct commercial and international banking in markets where both parent institutions saw opportunities for trade finance, corporate banking, correspondent relationships, and regional financial services. Rather than functioning primarily as a domestic retail bank in one country, BOLAM was designed as a cross-border network. Its geographic footprint included parts of Latin America, the Caribbean, and the West Indies, and it expanded through new branches as well as inherited operations. In 1959 it opened a branch in Jamaica, followed by a Trinidad branch in 1960. By 1970, the institution had 28 branches across Latin America and the Caribbean. BOLAM's ownership and structure changed during the 1960s. In 1965, Mellon National Bank acquired a minority shareholding of 15 percent. The transaction reduced Lloyds' effective interest to 24 percent, while the Bank of Montreal remained a major participant. BOLAM also adjusted its Venezuelan operations during this period, closing its offices in Venezuela and acquiring a substantial holding in Banco La Guaira Internacional, which operated in Caracas and La Guaira. In 1968, the Bank of England permitted Mellon to increase its interest to 25 percent. The joint-venture model did not last indefinitely. In 1970, BOLSA purchased BOLAM, ending the original 50-50 structure. The Bank of Montreal's former regional operations were subsequently separated or transferred in several markets. In Trinidad and Tobago, the government's acquisition of the Bank of Montreal's operations helped finance the creation of National Commercial Bank, an institution that later became associated with First Citizens Bank. In Jamaica, the government bought the Bank of Montreal's operations in 1971 and renamed them Bank of Surrey, although that institution closed five months later. Other BOLAM-related operations were incorporated into successor organizations connected with Lloyds and the Bank of Montreal. BOLAM's absorption also formed part of a broader Lloyds international-banking reorganization. In 1971, Lloyds combined Lloyds Bank Europe, BOLSA, and BOLAM into Lloyds and Bolsa International Bank. Lloyds held a majority stake and Mellon Bank retained a minority interest. Lloyds later acquired Mellon and the other minority holdings, after which the institution was renamed Lloyds Bank International. BOLAM therefore ceased to operate as an independent branded bank, even though elements of its branch network and business continued under successor institutions. The former BOLAM network included a Tokyo branch opened in 1971; Lloyds Bank International closed that branch in 1975. Later changes to related Bank of Montreal operations in the Bahamas and the Caribbean further fragmented the original network.

History

The Bank of London and Montreal Limited was established in 1958 as an equal joint venture between the Bank of London and South America and the Bank of Montreal. The former was connected with Lloyds Bank and brought an established branch presence in northern South America and the West Indies. The Bank of Montreal contributed capital. The new institution selected Nassau, Bahamas, as its headquarters and pursued a regional international-banking model rather than concentrating on one domestic market. The bank expanded its network soon after formation. It opened a Jamaican branch in 1959 and a Trinidad branch in 1960. Its operations covered commercial and international banking in Latin America and the Caribbean, using branches and local banking investments to serve regional customers and cross-border commerce. The institution was also granted a coat of arms by the College of Arms in March 1960. Ownership became more complex during the 1960s. Mellon National Bank acquired 15 percent of BOLAM in 1965, reducing Lloyds' stake to 24 percent. BOLAM closed its Venezuelan offices and acquired a substantial interest in Banco La Guaira Internacional, which had branches in Caracas and La Guaira. In 1968, the Bank of England authorized Mellon to increase its holding to 25 percent. In 1970, BOLSA bought BOLAM. At that point BOLAM had 28 branches across Latin America and the Caribbean. The transaction was followed by the redistribution and renaming of related operations. The Bank of Montreal transferred its Trinidad and Tobago branches and operations to the government, which used the proceeds to establish National Commercial Bank. That institution is now associated with First Citizens Bank. The Bank of Montreal's Jamaican operations were sold to the Jamaican government in 1971 and renamed Bank of Surrey, which closed five months later. BOLAM's absorption was part of a wider Lloyds restructuring. In 1971, Lloyds merged Lloyds Bank Europe, BOLSA, and BOLAM into Lloyds and Bolsa International Bank. Lloyds held 55 percent and Mellon Bank 13 percent. Lloyds subsequently bought out Mellon and the remaining minority investors, and the institution was renamed Lloyds Bank International. The former BOLAM Tokyo branch, opened in 1971, was closed in 1975. The Bank of Montreal's remaining Caribbean businesses also developed through later successor arrangements. In 1983, Bank of Montreal Bahamas Limited became the name of the Bahamian operation. When the Bank of Montreal announced in 1988 that it intended to withdraw from the Bahamas, the Bahamian government intervened. A joint business involving the government and Euro Canadian Bank eventually led to the institution known as Bank of The Bahamas, later associated with International Bank of the Bahamas. These successor developments illustrate how BOLAM's original regional network was gradually dispersed among government-backed and larger international banking institutions. BOLAM itself no longer exists as an independent bank.
