The recent government shutdown will create a permanent void in crucial economic data for October. While statistics like payrolls might be collected retroactively, survey-based data such as the Consumer Price Index (CPI) and household unemployment figures are likely lost forever due to recall bias, creating a black hole in the historical record.

A shutdown doesn't just delay data reports; if it extends into mid-month, it prevents the government from conducting the surveys needed for future reports. This disrupts the entire data collection pipeline, causing a ripple effect that can obscure economic trends for months after the government reopens.

Due to budget and staffing cuts at the Bureau of Labor Statistics, more than 33% of the Consumer Price Index is now estimated rather than directly surveyed. This significant increase in imputation questions the reliability of a key metric for economic policy.

The Fed's data-dependent policy is hamstrung by the government shutdown. If the shutdown persists, the lack of data itself becomes a signal of economic harm, potentially forcing the Fed to implement an "insurance" rate cut based on assumption rather than evidence.

Unlike the 2018 shutdown, the Bureau of Labor Statistics may not have funding this time, potentially halting the release of non-farm payrolls and CPI data. This would leave the highly data-dependent Federal Reserve and markets "flying blind" at a critical monetary policy juncture.

Declining real-term funding at agencies like the BLS creates a hidden cost. To ensure core reports are released on time, staff are pulled from long-term modernization projects, compromising the agency's ability to keep up with a changing economy.

The most significant danger of a prolonged government shutdown is the disruption to federal statistics. This creates an "unsettling" lack of visibility for policymakers, potentially causing them to miss a critical economic downturn and delay a necessary response. The direct GDP impact is often recoverable later.

Shutdowns halt the release of key data like jobs reports and inflation figures. This obstructs the Federal Reserve's ability to make informed interest rate decisions, creating market uncertainty. It also delays Social Security COLA calculations, impacting millions of retirees who rely on that data.

The Federal Reserve is not 'flying blind' during government shutdowns that halt official statistics. It uses a composite of alternative indicators for the labor market and inflation, providing enough of a signal to stick to its pre-planned policy path, such as proceeding with scheduled interest rate cuts.
