The partial federal government shutdown, now into its fourth week, is having an impact on ABS and MBS issuers that register deals with the Securities and Exchange Commission.

The federal government shutdown is affecting business operations of Ginnie Mae, forcing the government guarantor to scuttle its annual summit with issuers and delaying progress on “liquidity letters.”

Wells Fargo’s second post-crisis jumbo MBS differs from the one it issued in October. The new deal is substantially larger than the previous issuance and the lineup of three rating services is somewhat different.
