The Insurance Information Institute (I.I.I.) Inflation Watch spreadsheet contains the latest consumer price data from the U.S. Department of Labor Bureau of Labor Statistics (BLS). The CPI-U—the popular measure of consumer prices, sometimes called headline inflation—rose by 2.7 percent in August 2018 vs. August 2017. The core CPI—the overall index minus the effects of price changes for food and energy—rose 2.2 percent for the 12 months ending August 2018—the fourth month in a row in which the 12-month increase was between 2.2 percent and 2.4 percent. (Most economists prefer to use the core, not the headline, inflation measure to avoid the “noise” of volatile prices for those items.) The core PCE deflator—the inflation measure that the Federal Reserve prefers—rose by 2.0 percent on a year-over-year basis in July 2018 (the latest available reading). This is the fifth month in a row in which the core PCE deflator was between 1.9 percent and 2.0 percent. Many forecasters project headline CPI for 2018 to range between 2.3 and 2.7 percent. However, price trends for items that more directly affect property/casualty (P/C) insurance claims do not necessarily follow broad-based price indexes.
Prices for items such as intensive healthcare affect claims under third-party coverages such as workers compensation and bodily injury liability, as well as first-party coverages like Personal Injury Protection (PIP), med pay and obviously, medical expense insurance. For many years these price increases have far outpaced headline and core inflation, but in July and August 2018, this changed. In August 2018, seasonally adjusted on a year-over-year basis, prices for inpatient hospital care rose by 3.6 percent. Price increases for outpatient hospital care rose by 3.8 percent. These are the lowest year-over-year increases in hospital prices since the third quarter of 2015. Price increases for prescription drugs over the last 18 months have been quite variable. Prescription drug prices fell in each of the first three months of 2018, in July 2018, and were flat in August; thus in part as a result, the increase in August 2018 over August 2017 was 0.8 percent. A year-over-year increase that low last occurred in October 2013—nearly five years ago.
Price increases relating to auto insurance property claims have been quite moderate recently. Prices for motor vehicle parts and equipment, which affect not only comprehensive and collision claims, but property damage liability as well, rose by 0.4 percent in August 2018 vs. August 2017. Parts-and-equipment prices have been flat or falling consistently since 2012 and are now about the level reached in July 2011. Prices for motor vehicle repair rose by 1.4 percent for the 12 months ended August 2018. Prices for motor vehicle body work rose by 3.3 percent year-over-year (not seasonally adjusted). The BLS survey of consumer prices for motor vehicle insurance in August 2018 rose by 6.4 percent year-over-year. This is the lowest year-over-year increase in motor vehicle insurance prices in two years. Of course, factors other than prices for auto repair—such as the continued low level of insurer investment income and continued above-CPI growth in the prices for hospital care—likely are factors.
The Census Bureau computes a price index for new single-family houses under construction. The latest data (for July 2018) shows a 3.6 percent increase over the index in July 2017. However, the National Association of Home Builders, which tracks the price of framing lumber, reported that in August 2018 their index rose by 8.7 percent over the index a year earlier.
Media stories about inflation are partly traced to belief that, since the economy is nearing (or is at?) full employment, employers will have to hike wages further to attract needed workers, and that wage increases will morph into consumer price increases. Wages have indeed been rising above the rate of inflation. The Bureau of Labor Statistics reported that, on a year-over-year basis, average weekly earnings of private sector employees grew by 3.2 percent in August 2018 over the prior August, but these economy-wide numbers obscure variations in particular industries. For example, average weekly earnings in August 2018 vs. August 2017 rose by 4.4 percent in the construction industry, but only by 2.3 percent in manufacturing. On the services side, average weekly earnings rose by 5.0 percent in the financial activities industry, but only 2.9 percent in the education and health services industry. Wage growth affects workers compensation and, indirectly, liability and PIP claims. On the plus side, wage growth above inflation means consumers have increased buying power, which could lead to stronger economic growth near-term. In confirmation of this analysis, the advance estimate of retail sales in August 2018 was 6.6 percent higher than in August 2017 (not adjusted for inflation).
One additional price bears watching: the price of money (interest rates). The Federal Reserve’s Open Market Committee is likely to continue through 2018 to raise the short-term “fed funds” rate, which often drives interest rates for longer-term loans. Long-term interest rates will likely also rise because of substantial additional borrowing by the federal government, both because of the recently-enacted federal income tax changes and the subsequent budget agreements. But even before the tax act and budget agreement, interest rates were rising. The yield on 10-year U.S. Treasury notes in August 2018 was 2.9 percent, up from 2.2 percent a year earlier. Higher long-term interest rates can be expected to have a dampening effect on economic growth, but this could be offset by the short-term enhancing effects of more money in consumer and business pockets from the income-tax cuts. Higher interest rates will help P/C insurer investment income but could weigh on the capital gains element of investment gains, as the prices of currently-held low-yielding bonds fall.
