The BTFP has been actively utilized by the banks.

In essence, the Fed is giving the banks 1 dollar (newly printed) for bonds worth 70 cents. This is backdoor quantitative easing or yield curve control. And it’s unlikely to ever be unwound. Of course, the spin from the Government is that it is not a bail out, not a subsidy and not quantitative easing. All untrue, in our opinion.
