Ginnie Mae Pass-Through Security: Mortgage-Backed Investment

A Ginnie Mae Pass-Through Security is a type of mortgage-backed security guaranteed by the Government National Mortgage Association, passing through interest and principal payments from a pool of mortgages to investors.

Ginnie Mae Pass-Through Securities are a type of mortgage-backed security (MBS) that are guaranteed by the Government National Mortgage Association (GNMA or Ginnie Mae). These securities facilitate investment in residential mortgages by pooling multiple mortgage loans together and passing through the interest and principal payments from homeowners to investors.

Ginnie Mae Pass-Through Securities are constructed from pools of mortgages. The homeowners make mortgage payments to the originators, which can be banks or savings and loan institutions. These entities, after deducting a small service fee (typically 0.25% to 0.50%), pass the remaining payments to the security holders.

Example

  1. Homeowners in a Ginnie Mae pool make their monthly mortgage payments.

  2. The originating institutions collect these payments and retain a servicing fee.

  3. The remaining balance is forwarded to the Ginnie Mae Pass-Through Security investors.
