Freddie with FED leverage

Dealbreaker points out a nice trade:

A bank that bought the six month notes from Freddie this morning could also bid to borrow from the Fed's Term Facility, which held an $75 billion auction today. As collateral for the borrowing, the bank could offer the newly purchased Freddie notes, for which the Fed would give them credit for 97% of their market value. Recently, the TAF pricing topped out at 2.35 percent for 28-day borrowing. So a bank buying $100 million of Freddie paper yielding 2.858% could flip it to the Fed, borrowing $97 million at around 2.4% (assuming the pricing will be slightly higher this time around).

At the end of the day, a credit desk could buy $100 million of Freddie debt for just $3 million down. On that $3 million, the desk would receive a 17.7% annualized return, or 8.8% over six months.

If you believe in the Treasury guarantee of the GSEs, and I think I do, that's not a bad return.
