It’s Time to Dump Argentina’s Peso

As Milton Friedman put it in his 1987 New Palgrave Dictionary of Economics entry “Quantity Theory of Money” (QTM), “The conclusion (of the QTM) is that substantial changes in prices or nominal income are almost always the result of changes in the nominal supply of money.” The income form of the QTM states that: MV=Py, where M is the money supply, V is the velocity of money, P is the price level, and y is real GDP (national income).

Let’s use the QTM to make some bench calculations to determine what the “golden growth” rate is for the money supply. This is the rate of broad money growth that would allow the Central Bank of Argentina (BCRA) to hit its inflation target. I calculate the “golden growth” rate for the past decade.

According to my calculations, the average annual percent real GDP growth over the past decade is 1.38 percent, the average annual growth in Total Money Supply (M3) is 32.47 percent, and the average annual change in the velocity of money is 0.87 percent. Using these values and the BCRA’s inflation target of 11 percent (the average of the BCRA’s inflation targets for 2010–2020), I calculated Argentina’s annual “golden growth” rate for Total Money Supply to be 11.51 percent.

Golden growth rate = 11% + 1.38% – (0.87%) = 11.51%

The “golden growth” rate is depicted in the chart below. Also included are the annual growth rates in the total money supply over the past decade, as well as the average, which is 32.47 percent. It is clear that the BCRA has wildly overshot the “golden growth” rate in the past decade. At present, the annual growth in the money supply is soaring at 53.71 percent — over 40 percentage points higher than the “golden growth” rate.

With money growing at over 50 percent per year, it’s no surprise that Argentines treat their pesos like hot potatoes — they attempt to exchange them for U.S. dollars as fast as they possibly can. In typical Argentine fashion, the BCRA on September 15 decided to further restrict Argentines’ access to U.S. dollars in the foreign‐​exchange market by keeping the dollar‐​purchase limit for savings at $200 per month, while increasing taxes that citizens pay on purchases of dollars to pay off credit‐​card debt or for saving to a whopping 35 percent.

Instead of limiting the liberty of Argentines to use their preferred currency, namely, the greenback, Argentina should mothball the BCRA and the pathetic peso and put them in a museum. It’s time for Argentina to officially dollarize. This would be an easy task to accomplish. At the request of then‐​president Carlos Menem, Dr. Kurt Schuler and I prepared “A Dollarization Blueprint for Argentina,” first published in Friedberg’s Commodity and Currency Comments Experts’ Report (February 1, 1999).

Although Menem failed to pull the trigger on dollarization in Argentina, it was feasible in 1999 and would have worked well, just as it would today. Indeed, it would allow Argentina to avoid the currency chaos, sky‐​high inflation, and ensuing devaluations and defaults that have wrecked Argentina since 1999.
