The Employment Cost Index (ECI) is a quarterly economic indicator that measures changes in the cost of labor in the United States, including wages, salaries, and employee benefits. It is published by the U.S. Bureau of Labor Statistics (BLS) and is widely used by economists, investors, and policymakers to understand labor market inflation and wage pressures.
The ECI is considered one of the most reliable measures of wage inflation because it tracks both earnings and benefits across industries, job categories, and compensation structures. Unlike simple wage reports, it accounts for non-wage costs such as health insurance, paid leave, and retirement plans.
Why the Employment Cost Index Matters
The ECI is important because labor costs are one of the biggest drivers of inflation. When wages and benefits rise rapidly, businesses often raise prices to cover costs, influencing inflation and interest rates.
Key reasons the ECI matters:
- Indicator of inflation: Higher labor costs often signal rising inflation.
- Guides monetary policy: The Federal Reserve closely watches ECI data when adjusting interest rates.
- Affects corporate earnings: Companies facing higher compensation costs may report lower profits.
- Impacts financial markets: Strong ECI growth often leads to expectations of tighter monetary policy, affecting stocks, bonds, and currencies.
How the Employment Cost Index Works
The ECI is calculated by comparing labor cost data from thousands of businesses, covering over 27,000 job categories across the private sector and government. It includes:
- Wages and salaries
- Employer-paid benefits
- Industry and occupation adjustments
- Seasonal variations (removed for reporting clarity)
Reporting
- Frequency: Quarterly (January, April, July, October)
- Source: Bureau of Labor Statistics (BLS)
- Measurement: Percent change from the previous quarter and year
Components of the Employment Cost Index
The ECI has two main components:
1. Wages and Salaries
This covers base pay, commissions, and bonuses.
2. Benefits
This includes:
- Health insurance
- Social Security contributions
- Paid leave
- Retirement plans
- Supplemental pay
Each component is weighted according to industry employment levels to ensure accuracy across the economy.
Importance of the Employment Cost Index in Financial Markets
Traders and investors monitor the ECI because it strongly influences inflation expectations and monetary policy decisions.
Market Impacts:
Stocks
- Higher-than-expected ECI: May cause stock prices to fall due to rate hike fears and rising business costs.
- Lower ECI: Can boost markets by signaling slower inflation and stable profit margins.
Bonds
- Rising ECI → Rising yields (falling bond prices) as markets expect higher inflation and Fed tightening.
- Falling ECI → Falling yields (bond prices rise).
Forex
- Strong ECI may strengthen the U.S. dollar as interest rate expectations increase.
Employment Cost Index vs. Other Wage Measures
Metric | What It Measures | Strengths | Weaknesses |
ECI | Total labor costs (wages + benefits) | Adjusts for job mix changes | Not monthly |
Average Hourly Earnings (AHE) | Hourly wage growth | Released monthly | Excludes benefits |
Unit Labor Costs | Compensation vs. productivity | Shows labor productivity trends | Less granular |
The ECI is widely viewed as more comprehensive than other indicators because it includes benefits and neutralizes job mix shifts.
