Overview
AMRO Bank was a major Dutch banking institution whose name derived from Amsterdam and Rotterdam, the cities associated with its two predecessor banks. It was created in 1964 through the merger of Amsterdamsche Bank, founded in 1871, and Rotterdamsche Bank, founded in 1863. Although merger discussions had occurred before the Second World War, the plans were postponed in anticipation of the Netherlands becoming involved in the conflict. The two banks eventually announced their combination on 11 June 1964, and integration took place during the following year. The new bank was established during a period in which Dutch financial institutions were expanding their scale, broadening their geographic reach and developing more specialized forms of credit. From its beginning, AMRO pursued growth in business lending, leasing, factoring and medium- to long-term finance. It created the Nationale Bank voor Middellang Krediet as a business unit for medium- and long-term credit, and developed specialist financing activities through businesses including Mahuko, a leasing company, and Amstel Lease. Factoring activities were consolidated in International Factors Nederland B.V., described in the historical record as the oldest factoring company in the Netherlands. During the 1960s and 1970s, retail banking became a substantially more important part of AMRO's activities, reflecting the broader expansion of consumer and household banking in the Netherlands. At the same time, the bank strengthened its wholesale and investment-banking capabilities. In 1975 it acquired Pierson, Heldring & Pierson, commonly known as PHP, and retained it as an independently operated unit under its established name. AMRO also acquired the Utrecht-based Bank Flaors & Ko, an institution with roots extending back to 1691, and subsequently incorporated it into the AMRO Bank organization. AMRO also sought to participate in the development of a more integrated European banking market. In 1967 it helped establish Banque Européenne de Crédit à Moyen Terme, a Belgian-based consortium bank intended to provide sufficient scale for international activities. It later announced a proposed collaboration with Belgium's Generale Bank to build a European international bank. That project did not materialize, but the ambition anticipated the cross-border consolidation that later shaped European banking. The decisive event in AMRO Bank's history was its combination with Algemene Bank Nederland, generally known as ABN. Dutch government changes to merger rules for financial institutions made the transaction possible. On 24 August 1990, the shares of ABN and AMRO were converted into shares of a newly established holding company, ABN AMRO Holding N.V. The two banking organizations were subsequently combined, and in 1991 they formed ABN AMRO Bank. AMRO therefore ceased to operate as an independent bank. Its principal historical legacy is as one of the two predecessor institutions of ABN AMRO and as an example of the consolidation, specialization and internationalization of Dutch banking in the second half of the twentieth century.
History
AMRO Bank emerged from the consolidation of two established Dutch banks. Amsterdamsche Bank had been founded in 1871, while Rotterdamsche Bank traced its origins to 1863. The institutions considered combining as early as 1939, but postponed the plan because of the expected Dutch involvement in the Second World War. Their merger was formally announced on 11 June 1964, and the organizations were integrated during the subsequent year. The resulting Amsterdam-Rotterdam Bank was commonly abbreviated as AMRO Bank. AMRO's early strategy focused on expanding its position in business finance. It developed lending for companies, medium- and long-term credit, leasing and factoring. The bank established Nationale Bank voor Middellang Krediet for medium- and long-term lending, and created or acquired specialist businesses including Mahuko and Amstel Lease. Factoring was organized through International Factors Nederland B.V. These activities gave AMRO a broader financial-services platform than a conventional deposit-and-loan bank. Retail banking expanded considerably during the 1960s and 1970s, in line with the growth of mass-market banking in the Netherlands. AMRO simultaneously enlarged its wholesale capabilities. Its 1975 acquisition of Pierson, Heldring & Pierson added a significant specialist and wholesale operation, which AMRO preserved under the PHP name. The bank also acquired Utrecht-based Bank Flaors & Ko, an institution with a history dating to 1691, and brought it under the AMRO Bank brand. The bank pursued cross-border ambitions as European financial integration developed. In 1967 it helped found Banque Européenne de Crédit à Moyen Terme in Belgium, a consortium intended to create an institution large enough to operate internationally. AMRO later explored a partnership with Belgium's Generale Bank to create a European international bank. That proposal was not completed, illustrating the practical difficulties of building a pan-European banking group before later regulatory and market integration. AMRO's independent history ended through its merger with Algemene Bank Nederland, or ABN. Dutch authorities had relaxed merger rules for financial institutions, allowing the two large Dutch banks to combine. On 24 August 1990, their shares were exchanged for shares in a newly established ABN AMRO Holding N.V. The combined banking group was formed in 1991 as ABN AMRO Bank. AMRO Bank consequently became a historical predecessor rather than an active standalone brand. Its legacy encompasses the Dutch bank-consolidation movement, the rise of specialized corporate finance, the expansion of retail banking and the early pursuit of European banking scale.
