Adventures in Conditional Forecasting

Key Takeaways

• Brent crude sits near $117, keeping headline CPI elevated.
• If Brent falls to $70, inflation rate drops but price level steadies.
• Kalshi markets assign roughly 50% probability to reopening by Sept 1.
• Post‑reopening oil flow likely below pre‑war levels, limiting deflation.

Pulse Analysis

The ongoing conflict in the Strait of Hormuz has pushed Brent crude to roughly $117 per barrel, a level that feeds directly into headline consumer‑price inflation. Higher energy costs raise transportation and production expenses, keeping the CPI index stubbornly high despite robust consumer spending. Analysts at the Council of Economic Advisers, represented by Pierre Yared, argue that price relief hinges on a definitive end to hostilities, yet the geopolitical timeline remains opaque, creating uncertainty for both markets and policymakers.

To quantify that uncertainty, the author builds a conditional forecast that assumes a rapid oil‑price correction once the strait reopens. Using Kalshi’s 50‑percent odds for a September 1 reopening, the model projects Brent falling to $70, with 70% of the price gap erased within three months. A log‑linear relationship between oil, core CPI, and headline CPI suggests the inflation rate would decelerate sharply, but the CPI level would barely budge because the price base is already elevated. Even under the most optimistic flow‑recovery scenario, the analysis notes that infrastructure damage will likely keep oil shipments below pre‑war capacity, capping any deflationary pressure.

The practical takeaway for the Federal Reserve and investors is that disinflation, not outright deflation, will dominate the near‑term outlook. Monetary policy may need to stay restrictive longer than a simple oil‑price decline would suggest, as the underlying price level remains sticky. Energy‑focused hedge funds and commodity traders should monitor real‑time flow data and geopolitical developments closely, while corporate budgeting teams must factor in the possibility of sustained higher input costs despite a softer headline inflation rate.
