On March 23rd, the US Fed stopped publishing figures for the M3 measure of money supply. They said that the measure was outmoded and the costs associated with measuring and publishing it outweighed the benfits. M3 is, or rather was as far as the US is concerned, the broadest measure of money supply, taking into account such interesting aspects as EuroDollars, large-denomination time deposits, and repurchase agreements, all of which will no longer be published. What this means is that it will no longer be possible to measure the true amount of dollars circulating in the world and without that it will be next to impossible to guage the true value of the dollar. Now of the previously mentioned components of M3, that is those components over and above those of the lesser aggregate, M2, the most interesting seems to be Eurodollars. This measures the value of all US dollar accounts held outside the US. Coincidentally, March was also the month when Iran's Bourse was scheduled to open, a securities exchange that trades in Euros rather than dollars. As yet, I haven't found out if the Iranian Bourse did actually start trading, but it was scheduled to begin on 20th March. And three days later the US Fed stops publishing M3. Coincidence? Interestingly, blogworld is for the most part split over what impact the Iranian Bourse would have. Ranging from monetary apocalypse as oil trading flees from the dollar to the Euro, all the way to little or no effect. Doubtless, the actual impact would be somewhere in between initially, but conceivably rise as time progresses. However, the disappearance of M3 does have other implications. If, over time, the Petrodollar is usurped by the petroeuro - if oil is traded in euros rather than dollars - then countries holding necessary securities (typically treasury bonds) to cover their trades, will be cashing them in, exchanging them for Euros and making their trades. Without M3 as a measurement, the US Fed can expand the dollar money supply in order to facilitate these demands without it being noticed so easily. But of course, economics isn't that simple and over time, a rapidly expanding money supply will lead to inflation and a consequent devaluation of the currency. To offset this, the only viable course is to increase interest rates, which will have an impact on things like debt, stock prices, housing start ups and such like. The other downside is, traders aren't idiots. While the disappearence of M3 had for the most part gone unnoticed, the traders aren't so blind. Recent rises in gold, oil, copper etc, might just be a reaction to what the traders believe is behind the demise of M3. Naturally, conspiracy theorists are having a field day over this, and who can blame them. Add into the mix the resignation of Greenspan in January, the stoking up of rhetoric against Iran and you have a wonderful coincidence of events that just invites connecting. Simon
