The Stone Age of Economic Reporting: Skip the Archaic Methodologies When Assessing the Market

The U.S. Bureau of Labor Statistics (BLS) plays a crucial role in shaping our economic narrative, producing data on inflation, employment, and productivity that moves markets and guides Federal Reserve policy. Yet despite this outsized influence, the BLS continues to rely on antiquated methods that can distort reality. Two of its most consequential reports — the Consumer Price Index (CPI) for inflation and Non-Farm Payrolls (NFP) for employment — are calculated using outdated techniques that may be fueling unnecessary financial volatility.

With trillions of dollars in investments changing hands daily and critical Fed decisions hanging in the balance, it's worth asking: Why are we still making high-stakes economic policy based on lagging surveys and statistical approximations? The answer lies in a system that hasn't kept pace with modern realities.

CPI and the inflation ‘illusion’

The CPI helps determine everything from Social Security adjustments to eligibility for government assistance programs. As a major market-moving data point, accuracy should be non-negotiable. Yet the way we calculate it, particularly for housing costs (which make up 35% of the index), it is no longer current.

Consider January 2025: While the BLS reported shelter inflation at 4.4%, real-time rental data from platforms like Apartment List showed rents actually declining by 0.4%. Had the BLS incorporated the more current data, overall CPI might have been closer to 1.3%, marking a dramatic difference with real-world consequences for monetary policy.

Two core issues are to blame. First, the rent data the BLS uses is severely outdated, sometimes lagging by as much as a full year. This means that CPI figures often reflect past conditions, not the current environment. Second, the methodology incorporates something called Owners’ Equivalent Rent (OER), which doesn’t measure actual rents. Instead, it asks homeowners to estimate what they think their home could rent for on the open market. Unsurprisingly, most homeowners aren’t professional appraisers or landlords, making this method speculative at best.

As a solution to this conundrum, BLS could start incorporating real-time rental data from reputable housing platforms while reassessing the usefulness of OER entirely. Relying on market-based information, rather than homeowner guesswork, would provide a clearer, more accurate view of inflation and its far-reaching impacts.
