Inflation in the dollar zone

In a recent FRED Blog post, we showed how the exchange rate regime has had an impact on inflation rates in Europe. This time, we look at the dollar zone. Indeed, several countries have adopted the U.S. dollar as legal tender, and it is startling how their inflation rates have rapidly converged toward the U.S. rate. Just look at the graph. This convergence was likely the intention of those countries: Ecuador in 2000 and El Salvador in 2001 switched to the U.S. dollar to fight against very high inflation rates. Panama had already adopted the U.S. dollar in 1904 and has had no such problems with inflation.

How this graph was created: Search for “Inflation” and the respective countries. In the case of the U.S., change the units to “Percent Change from Year Ago” to match the units of the other series. The line width for the U.S. was increased and the color changed to black.

How the exchange rate regime drives inflation

This graph shows inflation rates for some of the countries that founded the euro zone. The sample period encompasses three exchange rate regimes: 1. The first is a fixed exchange rate under the Bretton Woods agreement, which allowed some adjustments but ones that were difficult to achieve. The countries’ inflation rates were similar in this period, with occasional exceptions. 2. This system collapsed in 1971 and gave way to a series of exchange rate arrangements with varying membership and success in limiting exchange rate fluctuations. The graph clearly shows that inflation rates varied considerably from one country to the next, which made it difficult to obtain relatively stable exchange rates. 3. Then came the creation of the euro in 1999. A major requirement of membership to this currency union was a low inflation rate maintained within a small range across candidate countries. The graph nicely shows the convergence in inflation rates, which has been maintained to this date.

How this graph was created: Search for “Inflation” and then limit the selection in the sidebar by choosing tags: “Nation” (under geography types) and “World Bank” (under sources).

Not all books are created equal

The evolution of consumer prices is not uniform across categories, and there can be stark differences between relatively similar products. In the example above, we look at two types of books: those used for recreation and those used for education. The paths of their price indices are very different, even in the long term. While this example is rather extreme, there are plenty of others in the disaggregated CPI data. This shows that one should not use personal experience with the price of a very specific product to draw conclusions about the general price level.

How this graph was created: Search for “CPI book.” To weed out the price indices from other countries, click on USA in the left sidebar tags. Select the two series, not seasonally adjusted (as one is not available seasonally adjusted). Finally, select a right axis for one series, as they have different index years.
