Overview
Dime Savings Bank of New York was a historic American savings institution headquartered in Brooklyn, New York City. Chartered in 1859 as the Dime Savings Bank of Brooklyn, it took its name from the unusually low minimum needed to open an account: one dime. The institution was created to serve ordinary savers and developed around the traditional savings-bank model, accepting deposits and providing mortgage and other consumer-oriented banking services. As Brooklyn grew during the late nineteenth and early twentieth centuries, Dime moved between locations before establishing a major home office in Downtown Brooklyn. Its landmark headquarters at 9 DeKalb Avenue was designed by Mowbray and Uffinger and constructed between 1906 and 1908. The building was later enlarged in 1931–1932 and became an important architectural and civic landmark in Brooklyn. The bank’s location reflected the growing commercial importance of the area around Brooklyn Borough Hall and the expansion of transportation and business activity in the borough. Dime later operated through a corporate structure commonly identified with Dime Bancorp. Its regional footprint expanded beyond Brooklyn and New York City through acquisitions and branch growth. In 1994, Dime Bancorp announced the acquisition of Anchor Bancorp, the parent of Anchor Savings Bank, a transaction completed in January 1995. The combination produced a network of branches in New York, New Jersey, and Florida. During the late 1990s and early 2000s, Dime became involved in a series of strategic and legal contests involving larger banking organizations. A proposed merger of equals with Hudson United Bancorp was announced in 1999 but was terminated after North Fork Bancorporation launched a hostile takeover effort against Dime. Dime’s independent existence ended after Washington Mutual announced its acquisition of Dime Bancorp in June 2001. The transaction, valued at approximately $5.2 billion in cash and stock according to contemporary descriptions, was completed in January 2002. At that time, Dime had 123 branches in the New York City area across New York and New Jersey. The Dime name and operations were subsequently incorporated into Washington Mutual rather than continuing as an independent bank. Washington Mutual was seized and placed into receivership in 2008. The Federal Deposit Insurance Corporation arranged the sale of Washington Mutual’s banking assets to JPMorgan Chase, and former Dime assets were included in that transfer. Accordingly, Dime Savings Bank of New York is a defunct banking brand rather than an active standalone institution. The former DeKalb Avenue headquarters continued to have a post-bank life. Developers acquired the property during the 2010s and incorporated the historic bank structure into a larger mixed-use development that became The Brooklyn Tower. Restoration and adjacent tower construction were completed in the early 2020s. The site also became associated with a publicly accessible electric-vehicle charging hub operated by Revel. These later real-estate and infrastructure uses preserve the physical presence of Dime’s most recognizable headquarters even though the bank itself no longer operates.
History
Dime Savings Bank of New York began in 1859 as the Dime Savings Bank of Brooklyn. Its name reflected the institution’s original accessibility: a customer could open an account with as little as ten cents. The bank was established during a period when savings institutions were intended to encourage thrift among working households and other small depositors. Its core activities centered on deposit-taking, savings products, mortgage lending, and related retail banking services. The bank’s early offices changed as Brooklyn expanded. By the beginning of the twentieth century, Brooklyn’s incorporation into the City of Greater New York and the growth of transportation and commercial activity created demand for a more substantial central headquarters. A new building at DeKalb Avenue and Fleet Street was announced in 1905. Dime moved into the completed building on December 19, 1908. Designed by Mowbray and Uffinger, the neoclassical structure was later expanded in 1931–1932 by Halsey, McCormack and Helmer. It became a designated New York City landmark and remained the institution’s most visible architectural legacy. In the later twentieth century, Dime developed into a larger regional banking organization. Its corporate activities were associated with Dime Bancorp, and its growth increasingly involved acquisitions. In 1994, Dime Bancorp agreed to acquire Anchor Bancorp of Hewlett, New York, the parent of Anchor Savings Bank. Completed in January 1995, the transaction created a combined branch network in New York, New Jersey, and Florida. This expansion reflected the consolidation of the U.S. thrift and savings-bank sector, in which institutions sought greater scale and geographic reach. Dime then became involved in an unsuccessful sequence of merger and takeover discussions. In September 1999, Dime Bancorp and Hudson United Bancorp announced a merger of equals valued at about $2 billion in stock. Before the transaction could be completed, North Fork Bancorporation launched a hostile takeover attempt in March 2000. Dime focused on resisting North Fork, and the Dime–Hudson United agreement was terminated in April. North Fork eventually abandoned its effort in September after litigation between the parties. Washington Mutual offered a different route for Dime. In June 2001, Washington Mutual announced that it would acquire Dime Bancorp in a cash-and-stock transaction valued at approximately $5.2 billion. The acquisition closed in January 2002. Dime had 123 branches in the New York City area in New York and New Jersey when it was acquired. The transaction ended Dime’s existence as an independent banking institution and folded its customer-facing operations into Washington Mutual. The successor institution did not remain independent indefinitely. In 2008, Washington Mutual was seized and placed into receivership during the financial crisis. The FDIC sold Washington Mutual’s banking assets to JPMorgan Chase, and assets formerly associated with Dime were included in that transfer. Dime therefore became a historical brand whose banking operations continued through successor institutions rather than under its original name. The DeKalb Avenue property remained significant after the bank’s disappearance. During the 2010s, the former headquarters and its surrounding site were acquired for redevelopment. Plans called for restoration of the historic neoclassical bank building and construction of a residential tower next to it. The resulting project, known as The Brooklyn Tower, preserved the former bank structure as part of a larger mixed-use development. The site later also became associated with a large publicly accessible electric-vehicle charging facility operated by Revel. The building’s continued public presence provides a tangible link to Dime’s Brooklyn history, even though the bank operated only from 1859 to 2002.
