Long-Term CPI Trends Since 1872: A Historical Perspective on Inflation - Crowd Sentiment Stocks

Live News

The financial research firm Advisor Perspectives has published an updated edition of its long-running analysis titled "Inflation Since 1872: A Long-Term Look at the CPI," prepared by the team at dshort (formerly Doug Short’s data-driven commentary). The report compiles monthly CPI data from the Bureau of Labor Statistics and extends the series back to the post-Civil War era using historical estimates. The analysis traces inflation through several distinct eras: the deflationary periods of the late 19th century, the World War I and II inflationary spikes, the post-war boom, the stagflation of the 1970s, the disinflation of the 1980s and 1990s, and the more recent low-inflation environment following the 2008 financial crisis. In recent years, inflation has re-emerged as a key economic concern, with the CPI showing notable upward movements during the post-pandemic recovery. dshort’s methodology applies a log-scale visual to emphasize percentage changes over time, making long-term trends more discernible. The chart includes major economic milestones such as the Great Depression, the oil shocks of the 1970s, and the 2008 global financial crisis. The analysis notes that while inflation has averaged roughly 3% annually over the very long term, short-term volatility can be significant. The report also compares headline CPI with core CPI (excluding food and energy), showing that long-term trends are largely consistent but that food and energy prices can introduce temporary noise. The current data, as of the most recent release, indicates that inflation remains above the Federal Reserve’s 2% target, though it has moderated from its peak in 2022. Advisor Perspectives cautions that historical data carries limitations due to changes in methodology and the basket of goods over time, but the long-term view remains a valuable tool for understanding inflation’s cyclical nature.

Key Highlights

Expert Insights

The long-term CPI perspective from Advisor Perspectives offers a crucial reminder that inflation is not a new phenomenon, nor is it uniform over time. While the recent inflation cycle has garnered significant attention, the historical data suggests that such episodes are part of a recurring pattern. However, each cycle has its own unique drivers—whether war, oil shocks, or supply chain disruptions—making precise forecasting difficult. From an investment standpoint, the analysis may encourage a focus on assets that have historically provided inflation protection, such as Treasury Inflation-Protected Securities (TIPS), commodities, and real estate. Yet caution is warranted: past performance does not guarantee future results, and the structural factors influencing inflation are constantly evolving. Policymakers at the Federal Reserve continue to monitor a broad range of indicators, and the long-term CPI data reinforces the idea that bringing inflation sustainably back to target could take time. The analysis from dshort does not offer a specific forecast, but it implies that inflation expectations remain an important variable for financial markets. Ultimately, the historical lens provided by this report may help investors avoid overreacting to short-term fluctuations while maintaining a disciplined approach to risk management. As always, individual circumstances and diversification should guide any investment decisions.
