# Crude Oil Stocks Change

## Data Summary

**Week Ending February 27, 2026**

- **Actual:** +3.475 million barrels (build)
- **Forecast:** 2.3 million barrels
- **Previous Week:** +15.989 million barrels
- **Surprise vs. Forecast:** +1.175 Mbbl (larger build than expected)

## Context

Crude oil stocks increased by 3.475 Mbbl during the week, exceeding the forecast of 2.3 Mbbl by 1.175 Mbbl. Stocks of crude oil refer to the weekly change of the crude oil supply situation. This is the most closely watched petroleum indicator.

## Assessment

The build exceeded expectations, signaling continued inventory accumulation despite moderating from the prior week's sharp 15.989 Mbbl build. The elevated build pattern suggests continued crude inflows or demand softness. However, the slowdown from the prior week indicates the pace of accumulation is normalizing. Combined with the contraction in crude imports (-19,000 bbl/d), this suggests domestic refinery positioning is adjusting to demand conditions.
