Contrary to the long-term belief that AI will be deflationary, the current surge in demand for computer equipment for data centers is stronger than supply, causing prices to spike and contributing significantly to producer price inflation (PPI).

Post-pandemic, companies have shifted from setting prices on a fixed schedule to "state-dependent pricing." They now adjust prices more frequently in direct response to rising costs, causing inflation to pass through to consumers more quickly and persistently.

Kai Ryssdal explains that the current rise in consumer prices is a lagging effect of tariffs. For months, businesses absorbed these costs to protect market share. Now, with squeezed margins, they are forced to pass the costs on to consumers, resulting in a delayed but significant inflationary impact.

Contrary to narratives about excess demand, the recent inflationary period was primarily driven by supply-side shocks from COVID-related disruptions. Evidence, such as the New York Fed's supply disruption index accurately predicting inflation's trajectory, supports this view over a purely demand-driven explanation.

The inflationary impact from the Middle East war will persist well beyond initial gasoline price hikes. Secondary effects on airline fares, diesel fuel, transportation, and agricultural inputs will continue for months, eventually causing an acceleration in core CPI, not just the headline figure.

Robert Kaplan cautions against dismissing inflation risks. Many businesses are still absorbing tariff costs or working through pre-tariff inventory. He believes the full price impact will be passed on to consumers in 2026, potentially keeping inflation stickier than markets currently expect.

It's the volatility and unpredictability within the supply chain environment—rather than the magnitude of a single shock—that can dramatically amplify the inflationary effects of other events, like energy price spikes. This suggests central banks need situation-specific responses.

To predict future price changes for consumers, one should analyze the producer inflation report, not just the consumer report. Businesses experience rising costs first and typically pass these increases on to customers later. A high producer inflation rate suggests consumer inflation will soon follow.

Recent data paints a conflicting picture. While forward-looking indicators for housing and the job market point to a softening economy, inflation metrics like the Producer Price Index (PPI) remain stubbornly high. This combination suggests a move toward a stagflationary environment.
