We know that inflation means more money chasing the same amount of goods. It means that it costs $7.25 to see the same movie you could have seen last month for $7.00. That extra quarter is inflation. In part 1, we learned that the government produces the Consumer Price Index (CPI) in an effort to quantify the overall inflation experienced by American consumers. Now we turn our attention to why CPI is important. If you think CPI is just another statistic released by the government, you might be surprised to find out how important CPI is. Here are some of the ways CPI affects Americans:
CPI and the Federal Reserve
CPI directly affects Federal Reserve policy because Core CPI (CPI-U less food and energy) is the Fed’s preferred measure of inflation. There is no official target rate of inflation, but some argue that we should have one. Various higher ups at the Fed have repeatedly stated that the target rate of inflation is 1-2% per year. Because interest rates and inflation tend to be inversely related, the Fed is likely to raise interest rates (constricting the money supply) if inflation is above target. If inflation looks to be below target, the Fed is more likely to lower interest rates (increasing the money supply).
William Poole, president of the Federal Reserve Bank of St. Louis, said, “I’ve often said my preferred target rate of inflation is ‘zero, properly measured. ’ That is, allowing as best we can for measurement bias, which might be around a half a percent per year for broad consumer price measures, I favor literally zero inflation. Given measurement bias in price indexes, I might state my goal as inflation between 0.5 and 1.5 percent as measured by the personal consumption expenditures (PCE) price index.” Mr. Pool is referencing the PCE index, which is a different price index although similar to CPI.
The St. Louis Fed President makes an interesting point. He says that he wants zero inflation but that he might set his inflation target between .5 and 1.5 percent to compensate for “measurement bias in the price indexes.” That means that Mr. Pool thinks that the indexes that seek to measure inflation are actually overstating inflation. What happens when a different member of the FOMC thinks that the inflation indexes are accurate when Mr. Pool thinks they might be off .5 to 1.5 percent? I guess those are the kind of debates that take place behind closed doors at FOMC meetings.
Officially targeting inflation is under debate, but whether or not it is made official (meaning the government would release an official target number for inflation), inflation affects monetary policy. Of course, monetary policy affects the life of every American, which means the accuracy of the Consumer Price Index affects your quality of life and mine, whether or not we are aware of it. Interestingly, the Federal Reserve likes to focus on core inflation, a measure that eliminates food and energy, which in itself is controversial.
Real GDP
Real Gross Domestic Product (GDP) is calculated after inflation. If inflation were understated, the result would be overstated GDP. The higher inflation, the lower real GDP. Obviously, the government likes to see low inflation so that real GDP — or growth — is not negatively impacted.
TIPS
Treasury Inflation-Protected Securities (TIPS) are a special type of Treasury note or bond that offers protection from inflation. With normal fixed-income investments, investors bear the risk of inflation eroding their investment. However, TIPS are guaranteed to keep pace with inflation because they are adjusted utilizing the Consumer Price Index. Of course, if CPI is understated, TIPS aren’t actually protecting their investors from inflation. Interestingly, if inflation is understated, the government pays out less interest on its TIPS. That means the government saves money if CPI is kept low.
Social Security and Federal Retirement Cost-of-Living Adjustments (COLA)
CPI-W (a variant of CPI) is the index used to adjust grandma’s monthly check. Some believe that the government has intentionally manipulated CPI in an effort to understate inflation so that entitlement payments could be reduced without the burden of seeking Congressional approval. Reducing entitlement payments through backdoor tactics has the added benefit of avoiding public outcry. Economist John Williams says, “Social Security checks today would be about double had the various changes [to CPI] not been made.” However, many economists disagree with Mr. Williams, maintaining that CPI is very accurate. The important point to note here is that Social Security and Federal retirement cost-of-living adjustments are directly tied to inflation as measured by CPI. If CPI goes up, so does grandma’s social security check. It is clearly in the government’s interest for CPI to be low.
On a side note, there is a popular myth that social security benefits are tied to a CPI index that does not include food or energy. That is simply not true. The index used to determine the cost-of-living adjustment for social security benefits does indeed include food and energy.
As you can see, it is in the government’s best interest to keep inflation low. Low CPI means that the Fed is free to keep interest rates low, real GDP looks rosy, social security and retirement federal benefits paid out are lower, and less interest is paid out on Treasury Inflation-Protected Securities.
In part 3, we’ll talk about the changes that have been made to the CPI calculation. CPI was calculated the same from 1921 to 1983 when a major change was introduced. More changes came in 1999. Now CPI is very controversial. Critics say that CPI is a joke and that inflation is grossly understated. Proponents of the revised CPI calculation say that we now have a more accurate measure of inflation. We’ll talk about those changes in part 3 …
