Great point about the IORB - I suppose it transforms the question into why the Fed specifically chose to introduce the ON RRP as opposed to expanding the entities eligible to receive interest on reserves. I think that has already been asked on this site!

Why does the ON RRP facility need to be done on a collateralised basis?

(Asked by: username_0 on 2024-06-14)

In the context of the Fed, what are the reasons that the ON RRP facility is structured such that loans are collateralised?

If we assume the Fed has zero credit risk, what is the benefit of actually exchanging Treasuries for reserves? The Fed can be assumed to service the interest payment and principal the next day, so in theory the collateral is not needed.

Is it simply to prevent "volatility" on the commercial banks balance sheets, where the loan principal suddenly "disappears"?
