"Water water everywhere, and not a drop to drink" - Rime of the Ancient Mariner (Gustave Doré woodcut) In a recent paper , John Taylor rhapsodizes about bringing back the good ol' federal funds market: I think the case can be made for such a framework. Peter Fisher ran the trading desk at the New York Fed for many years, and knows well how these markets work. His assessment is that such a framework would work, saying “we could get back and manage it with quantities; it’s not impossible. We could just re-engineer the system and go back to the way we were.” I spent time in the markets for federal funds watching how they operated in those days, and I wrote up an institutional description of how good experienced people traded in these markets, and I developed a model showing how the market worked. The fed funds market is currently moribund , but just a few years ago it was buzzing with activity. Banks that didn't have enough reserves at the end of the day to meet requirem...

Freigeld , or stamp scrip, is designed to pay negative interest, but it can be re-purposed to pay positive interest. Remember when global interest rates were plunging to zero and all everyone wanted to talk about was how to set a negative interest rate on cash? Now that interest rates around the world are rising again, here's that same idea in reverse: what about finally paying positive interest rates on cash? I'm going to explore three ways of doing this. As for why we'd want to pay interest on cash, I'll leave that question till the end. ------- The first way to pay interest on cash is to use stamping. Each Friday, the owner of a bill—say a $50 note—can bring it in to a bank to be officially stamped. The stamp represents an interest payment due to the owner. When the owner is ready to collect his interest, he deposits the note at the bank. For example, say that 52 weeks have passed and 52 stamps are present on the $50 note. If the interest rate on cash is 5%, then th...

David Beckworth argues that the U.S. Federal Reserve should stop running a floor system and adopt a corridor system , say like the one that the Bank of Canada currently runs. In this post I'll argue that the Bank of Canada (and other central banks) should drop their corridors in favour of a floor—not the sort of messy floor that the Fed operates mind you, but a nice clean floor. Floors and corridors are two different ways that a central banker can provide central banking services. Central banking is confusing, so to illustrate the two systems and how I get to my preference for a floor, let's start way back at the beginning. Banks have historically banded together to form associations, or clearinghouses, a convenient place for bankers to make payments among each other over the course of the business day. To facilitate these payments, clearinghouses have often issued short-term deposits to their members. A deposit provides clearinghouse services. Keeping a small buffer stock o...

Recent posts by Adrian Hope Baille and Sina Motamedi have got me thinking again about the idea of the Federal Reserve (or any other central bank for that matter) adopting bitcoin technology. Here's an older post of mine on the idea, although this post will take a different tack. The bitcoin ethos enshrines the idea of a world free from the totalitarian control of central banks. So in exploring the idea of Fed-run bitcoin-style ledger, I realize that I run the risk of being cast as Darth Vader (or even *yikes* the Emperor) by bitcoin true believers. So be it . While I do empathize with the bitcoin ideal—I support freedom in banking—I rank the importance of bitcoin-as-product above bitcoin-as-philosophy . And at the moment, bitcoin is not a great product. While bitcoin has many useful features, these are all overshadowed by the fact that its price is too damn volatile for it to be be taken seriously as an exchange medium. This volatility arises because bitcoin lacks a fundamenta...
