In this podcast, my friend Brendan Walsh and I sat down with Stefan Rust, the CEO and founder of Truflation, a company aiming to revolutionize how we measure and understand inflation. In our interview on Feb 23, 2024, Rust explained how his motivation to start Truflation stemmed from the shortcomings in the way the Bureau of Labor Statistics (BLS) calculates and reports inflation data - a process that is flawed and does not accurately reflect the true cost of living increases experienced by consumers. Truflation takes a fresh, data-driven approach by monitoring millions of real-time pricing data points across various spending categories like housing, transportation, and utilities.

A key difference highlighted is Truflation's treatment of housing costs, which account for a 26% weighting compared to the BLS's 40%+ weighting. Truflation argues their housing data, pulled from real-time rental listings on sites like Zillow and Redfin, better reflects the true costs faced by consumers. In contrast, the BLS's housing data has a significant 9-month lag and relies on surveys of homeowners' estimates of rental values. Truflation also breaks down costs into 12 granular categories versus the BLS's 6 categories.

Transparency is a core tenet of Truflation's approach. Their methodology is fully documented and open to community feedback for improvements every 6 months. All original data is immutably recorded on the blockchain, allowing tracking of any methodological changes over time through new data streams. Truflation offers various services from raw data feeds to analyst reports and forecasting up to 3 months out, with their 1-month inflation forecasts proving accurate within around 10 basis points of reported BLS numbers on average.

A major advantage Truflation provides clients is the ability to access the raw data via APIs and calculate inflation measures based on their own preferred weightings across the 12 categories tracked. Some clients prefer leveraging Truflation's analyst interpretations through services like group webinars or one-on-one sessions. The goal is to provide options beyond just taking Truflation's headline inflation numbers at face value.

While the BLS revises its CPI numbers over time, often suppressing reported inflation according to Rust, all of Truflation's original data is immutably recorded to the blockchain. Rust acknowledges challenges in longer-term 3-month forecasting due to potential "black swan" events but believes Truflation's core innovation is providing a more real-time, transparent and accurate measure of true consumer inflation than traditional government sources by leveraging modern data sources and computing power.
