A description of the moneyness market


Imagine a market where buyers and sellers of moneyness congregate. In this post I'll flesh this market out.

By moneyness I mean the extra bit of value, or premium, ascribed to some good or asset because of its exchangeability. Assets that are more exchangeable, or liquid, will have a larger premium attached to them. Less liquid assets will have little to no premium.

Put more explicitly, let's say that Microsoft issues two types of shares, MSFT.A and MSFT.B. Both are entirely alike. They have the same dividend, carry the same voting rights, and are ranked equally in terms of seniority. The only difference is that MSFT.B shares are more exchangeable. Let's say that while MSFT.B can be sold whenever the owner wishes, MSFT.A can only be sold by their owner after one year has passed. A moneyness premium should emerge as the price of B shares trade above the price of A shares. Because the shares are entirely similar, this divergence can only be a product of B's superior liquidity services, a feature that investors willingly pay a premium to enjoy.

In our simple MSFT market, a buyer of moneyness prefers to pay up for higher priced MSFT.B in order to enjoy B shares superior liquidity. A seller of moneyness will trade away MSFT.B in order to purchase lower cost MSFT.A and bear the inferior liquidity of A shares.

We're more interested in a complex moneyness market that allows us to price the relative moneyness of all financial assets, not just MSFT.A and B.

We can start by establishing a centralized market. A seller of moneyness deposits their financial asset at an exchange, or clearinghouse, for a set period of time, say one year. In depositing their shares or bonds for a fixed term, the owner loses their right to transact in that asset over that time period. But they continue to enjoy all other rights associated with ownership, including dividends, interest, capital gains (or losses), and voting.

Interposing an exchange or clearinghouse between buyers and sellers of moneyness solves for credit risk. In futures markets, for instance, counterparties face no unique counterparty risk since the exchange promises that either side will be made whole should the other side default. Futures exchanges use performance bonds, or margin, to ensure that they can always meet their obligations. A moneyness market could also work along these lines.

Buyers of moneyness bid for the use of assets deposited at the exchange by sellers. Buyers have no right to any dividends, interest, or votes over that time period. But they earn the right to use that asset as a pure transactions asset. Buyers can repo it for cash, sell it, rent it out, use it as collateral, or mobilize it to settle trades. The range of transactions they can engage in is the same range of transactions that the seller of moneyness has chosen to forgo by depositing their asset for a fixed term.

At the end of the term, the moneyness buyer must return the deposited asset back to the seller. The price that competing buyers pay competing sellers in order to enjoy this range of transactional services over the fixed term of the deposit must be enough to compensate the seller for waiving these transaction opportunities. The price that these parties negotiate is equivalent to an asset's moneyness.

The exchange or clearinghouse might offer a range of fixed term deposits, say 1, 2, 3, 5, and 10 years, for various financial assets. A moneyness curve would develop, allowing investors to make intertemporal liquidity comparisons across the same asset.  For instance, in order to maximize returns would it be better to deposit MSFT for a two-year fixed term, or roll over two successive one year terms? This sort of question can be answered by looking at an asset's moneyness curve.

Establishing a market like this would also allow investors to make liquidity comparisons across different assets. For instance, a long term buy and hold investor might be able to deposit MSFT for five years and earn 0.15% a year for their troubles, but if they deposit GOOG for five years, they'll earn 0.20%. This will affect their initial purchasing decision, since buying GOOG and depositing it for five years will provide a greater return than buying and depositing MSFT.

Those assets that offer the highest deposit rates over a given time period will typically be the most liquid assets. After all, investors will require the greatest amount of compensation for forgoing the transactions services thrown off by assets with superior liquidity. Conversely, those assets that offer the lowest deposit rates will typically be the least liquid, since investors require little to no compensation for surrendering the stunted range of transactions services provided by illiquid assets.

Just like credit default swaps allow a bond owner to sell off the default risk to another investor, our centralized moneyness market would allow investors to sell away an asset's moneyness to someone else while keeping the real return component of an asset. Some possible economy-wide benefits this mechanism might provide:

1.  A moneyness market allows for a better allocation of liquidity amongst market participants. Those who don't need moneyness can sell it off while retaining the rights to the underlying asset. Those who want extra moneyness can purchase this quality without having to buy the entire asset.

2. By putting a price on liquidity, isolated pools of liquidity can be tempted back into the broader market in order to smooth out liquidity shocks.

3. Right now, getting information about the liquidity or illiquidity of various assets is difficult. A moneyness market allows us to build a precise market-based ranking of all assets, from stocks to bonds and debentures, to commercial paper, paper dollars, and mortgage backed securities, according to their relative moneyness. Information is usually a good thing.

Can you think of any other benefits? What are the negatives?

Stock as a medium of exchange

American Depository Receipt (ADR) for Sony Corp You've heard the story before. It goes something like this. There's one unique good in this world that serves as a universal vehicle by which we conduct every one of our economic transactions. We call this good "money". Quarrels often start over what items get lumped together as money, but paper currency and deposits usually make the grade. If we want to convert the things that we've produced into desirable consumption goods (or long-term savings vehicles like stocks), we need to pass through this intervening "money" medium to get there. This of course is fiction—there never has been an item that served as a universal medium of exchange. Rather, all valuable things serve to some degree or other as a medium of exchange; or, put differently, everything is money. What follows are several examples illustrating this idea. Rather than using currency/deposits as the intervening medium to get to their desired final...

Yap stones and the myth of fiat money

At first glance, the large circular discs that circulated on the island of Yap in the South Pacific certainly seem quite odd. Too big to be easily transported, the stones are often seen in photos resting against their owner's houses. So much for velocity. Yap stones have been considered significant enough that they have become a recurring motif in monetary economics. Macroeconomics textbooks, including Baumol & Blinder , Miles & Scott ( pdf ), Stonecash/Gans/King/Mankiw , Williamson , and Taylor all have stories about Yap stone money. Why this fascination? Part of it is probably due to the profession's obsession with the categorical divide between "money" and "non-money". In dividing the universe of goods into these two bins, only a few select goods end up in the money bin. That an object so odd and unwieldy as a three meter wide stone could join slim US dollar bills and easily portable silver coins in the category of money is pleasantly counterintu...

Chain splits under a Bitcoin monetary standard

The recent bitcoin chain split got me thinking again about bitcoin-as-money, specifically as a unit of account . If bitcoin were to serve as a major pricing unit for commerce on the internet, we'd have to get used to some very strange macroeconomic effects every time a chain split occurred. In this post I investigate what this would look like. While true believers claim that bitcoin's destiny is to replace the U.S. dollar, bitcoin has a long way to go. For one, it hasn't yet become a generally-accepted medium of exchange. People who own it are too afraid to spend it lest they miss out on the next boom in its price, and would-be recipients are too shy to accept it given its incredible volatility. So usage of bitcoin has been confined to a very narrow range of transactions. But let's say that down the road bitcoin does become a generally-accepted medium of exchange. The next stage to becoming a full fledged currency like the U.S. dollar involves becoming a unit of account...
