With the federal government shut down, several agencies are closing all but essential operations. Federal banking regulators—the CFPB, FDIC, Federal Reserve and OCC—will remain open as their funding does not come from congressional spending.
The SEC said it will use funds carried over from the previous fiscal year to remain open "for a few weeks." The Treasury Department and its congressionally funded agencies—including the IRS and the Financial Crimes Enforcement Network—are expected to halt most operations.
The Federal Housing Administration, as part of the Department of Housing and Urban Development, is partially closed, meaning that home loans requiring FHA approval may not be processed during the shutdown. Issuance of federal flood insurance policies may stop as well.
