Fed support for mortgage rates to end?

Official: MBS purchase program could be revisited

The Federal Reserve remains on course to wind down its purchases of mortgage-backed securities at the end of March, but would consider resuming them if mortgage rates shoot up with unintended consequences for the economy, a Fed official says.

The ongoing Fed purchases, which are expected to total $1.25 trillion by the end of next month, are widely credited with keeping mortgage interest rates near historic lows.
