I was intrigued by this passage, from Interfluidity:
Interest rates are, for the moment, excruciatingly low. But a subsidy
to the banking system, once put into place, will be quite hard to
dislodge. So, let’s imagine that the Fed will pay interest on bank
reserves in perpetuity, that it will pay such interest at or near the
risk-free short-term interest rate, and that the expansion of the Fed’s
balance sheet is more or less permanent. How large a subsidy to the
banking system do the interest payments on reserves represent? Some
problems are arithmetically challenging, but not this one. The present
value of a perpetual stream of market-rate interest payments is
precisely the amount of the principal. Therefore, the present value of
the Fed’s de facto commitment to pay interest to banks on $800B
of freshly created reserves is $800B. We fought and wailed and gnashed
our teeth over potentially overpaying for TARP assets. Meanwhile, we
are quietly allowing the Fed give away, as a direct, literal subsidy,
more than the entire $700B that Paulson was allowed to play with. Note
there is no question about this being an "investment": The interest
payments that the Fed is now making to banks on its suddenly expanded
balance sheet are not loans. The banks owe taxpayers absolutely nothing
in return for this windfall.
I take that calculation to be a very rough one, and possibly an overstatement, but the point remains of interest. It also can be argued that interest on reserves is a bad signal for at least two reasons:
1. It signals the Fed fears being left holding the intra-day Fedwire bag if a major bank goes under, and
2. It signals the Fed thinks major banks need such a subsidy.
The cited post is interesting throughout.
