STEPHEN BERNARDNEW YORK (AP) ¿ The crippled economy and increasing loan defaults have forced financial regulators to close even more banks, including the only branch of the First Bank of Kansas City, which is reopening under a new name after its deposits are assumed. The number of banks that have failed this year stands at 89 after regulators on Friday shut down banks in Missouri, Illinois, Iowa and Arizona. The Federal Deposit Insurance Corp., an independent agency whose goal is to maintain stability and public confidence in the financial system, took over First Bank of Kansas City, which was based in Kansas City, Mo., and had $16 million in assets and $15 million in deposits. It shut down Sioux City, Iowa-based Vantus Bank, with $458 million in assets and $368 million in deposits. First Bank of Kansas City's deposits will be assumed by Great American Bank, based in De Soto, Kan., the FDIC said. It was to reopen Saturday as a branch of Great American Bank. The FDIC seized two banks in Illinois: Oak Forest-based InBank, with $212 million in assets and $199 million in deposits, and Platinum Community Bank in Rolling Meadows, which had $346 million in assets and $305 million in deposits.
