Oil Settles Down 2% on Weak Demand Outlook and Record US Crude Inventory Build

The sharp reversal in oil prices on August 13 underscores how quickly fundamentals can override geopolitical optimism in energy markets.

After a six-session rally fueled by Middle East supply concerns, traders pivoted to bearish data from the US Energy Information Administration showing commercial crude stocks surging 17.4 million barrels—the biggest weekly increase in over three years—to 424.4 million barrels.

Exports also slumped, amplifying the glut signal. This coincided with lowered demand forecasts from both OPEC and the IEA for 2026, highlighting softening consumption in key regions amid economic uncertainty.

The move lower in Brent and WTI futures signals that markets are pricing in ample near-term supply even as tensions persist with Iran and Houthi activity threatens Saudi facilities.

Sectors most affected include upstream producers facing margin compression and downstream refiners who may benefit from cheaper feedstock, while shipping and LNG players monitor knock-on effects.

Traders should watch upcoming API and EIA inventory reports, any breakthrough in US-Iran or Hormuz shipping talks, and global PMI data for demand clues.

A sustained break below $85 Brent could accelerate selling toward $80 support, but renewed supply disruption headlines could quickly reverse the trend. Volatility is likely to remain elevated given the dual drivers of macro demand weakness and unresolved geopolitical risks.
