The United States failed to secure about one-third of the price data targeted in its September consumer inflation survey. Attention is on how uncertainty in inflation statistics could affect the Federal Reserve’s rate outlook and the bitcoin market.

On Oct. 26, blockchain media outlet CryptoSlate reported that the U.S. Bureau of Labor Statistics (BLS) had a 66.3 percent collection rate for September price data on goods and services. That was slightly higher than 65.9 percent in August but below 67.6 percent a year earlier.

The collection rate refers to the share of targeted data actually obtained in surveys of goods and services prices. It does not include housing costs surveyed separately or data collected through other channels. As a result, a 33.7 percent non-collection rate does not mean one-third of the overall Consumer Price Index (CPI) was filled with estimates.

The BLS scaled back or halted price surveys in some areas in the summer of 2025, then resumed hiring and training survey staff from November that year. It plans to widen the survey scope as staffing increases, but the data collection rate has yet to return to prior levels. The BLS explained that low response rates can raise the risk of statistical bias, but that alone does not allow a conclusion that bias has occurred.

Inflation indicators are an important variable for bitcoin because they influence the Fed’s rate decisions and risk-asset appetite. Investors use inflation trends to gauge the direction of monetary policy and investment conditions. Still, judging actual inflation to be higher or lower than reported based only on survey gaps could also lead to misreading the rate outlook.

Bitcoin has in fact reacted sensitively to higher-than-expected inflation. Coinbase said in a report on Oct. 16 that U.S. 2-year Treasury yields surged right after the September CPI release and bitcoin fell within hours from about $83,800 to below $82,000. Inflation data fuelled worries about additional rate hikes, weighing on prices.

In a report on Oct. 23, Coinbase also presented $80,000 to $82,000 as a key short-term support zone for bitcoin. It said failure to hold that range could test the next support zone of $73,000 to $75,000.

At the time, the probability of a December rate hike implied by the interest-rate futures market was about 80 percent. U.S. 2-year Treasury yields were also close to 4.8 percent. Coinbase analysed that an environment where investors can earn interest income simply by holding Treasuries can reduce the investment appeal of assets like bitcoin that do not generate their own interest.

Bitcoin’s 1-month implied volatility was about 35 percent, historically low, but funding rates for perpetual futures rose, showing an increase in leveraged long positions. That means the risk of sharp price swings and cascading liquidations could grow if the Fed sends signals that differ from market expectations.

Ultimately, the key is how far the Fed’s rate decision and future policy signals diverge from market expectations. Survey gaps alone cannot confirm distortion in inflation statistics, but if leveraged buying has increased, remarks signalling additional tightening could increase downward pressure on bitcoin.
