# Brent Rallies 4.2% To $87 As Crude Stocks Build 17.4M Bbl

13 August 2026 · OILAV

**Brent and WTI both gained over 4% on the week while crude inventories posted a 17.4M barrel build and crude volatility eased from its recent high.**

## Key levels

- Brent: support 81.5, resistance 90.07
- WTI: support 76.53, resistance 84.61

## Price Action & Technicals

> Both benchmarks closed near the upper half of their five-day range with volatility easing but still historically elevated.

Brent closed at **$87.07**, up **4.21%** over the five-session window, trading within a **$81.50–$90.07** range. WTI settled at **$81.25**, up **3.93%**, with a wider **$76.53–$84.61** band. Refined products outpaced crude: heating oil rose **8.92%** to **$4.25** and RBOB gasoline gained **4.78%** to **$3.13**, both closing near the top of their five-day ranges, while natural gas lagged with a **2.44%** gain to **$2.73**.

Crude Oil VIX (OVX) closed at **$49.36**, down **11.54%** on the window after touching a high of **$60.49**, indicating implied volatility has retreated from its peak but remains well above the low of **$49.11**, suggesting the options market has not fully unwound elevated risk pricing.

## Supply & Inventories

> A 17.4M barrel crude build alongside 96.2% refinery utilization signals the price strength is concentrated in the product complex, not the crude balance.

EIA data for the week ending 2026-08-07 shows crude stocks at **424.4M bbl**, a weekly increase of **+17.4M bbl** — a build of a magnitude that stands out against the concurrent price rally. Production held at **13.80M bbl/day** and imports at **7.34M bbl/day**, both unremarkable relative to recent levels.

Refinery utilization printed at **96.2%**, a high absolute level consistent with strong product demand pull, which aligns with the outsized gains in heating oil and gasoline versus crude itself. The combination of a large crude build alongside high refinery run rates points to product-side strength diverging from crude-side inventory data.

## Positioning & Flows

> Speculative positioning remains net long by more than 2-to-1, a level that has not yet been tested against the reported crude stock build.

CFTC data as of 2026-08-11 shows money manager net speculative length of **103,715 contracts**, built from **192,505 longs** against **88,790 shorts** — a long/short ratio of roughly **2.17:1**. Open interest stood at **2,608,236 contracts**.

This positioning, reported two days before the current price close, reflects a speculative base still tilted decisively long even as the crude stock build data emerged, leaving room for either continuation or unwind depending on how subsequent flows respond to the inventory print.

## Macro & Cross-Asset

> Macro indicators (DXY, yields, CPI, Fed funds) show no data-confirmed correlation with the day's crude price move.

The US Dollar Index stood at **119.1848** on the date, alongside a 10-Year Treasury yield of **4.63%**. The Federal Funds Rate was last recorded at **3.63%** (2026-07-01) and CPI at **332.813** for the same period.

No cross-asset series in this dataset shows a directional break coincident with the crude rally; dollar and yield levels are presented here as reference points only, with no causal link established by the data.

## What to watch

- Crude stocks posted a 17.4M bbl build against a rising price trend
- OVX remains above 49 despite an 11.54% pullback from its 60.49 high
- Refinery utilization at 96.2%, near the top of the observed range
- Net speculative length at 103,715 contracts with a 2.17:1 long/short ratio
- Heating oil (+8.92%) and RBOB (+4.78%) outperforming crude benchmarks over 5 sessions

## Risks to the view

- OVX at 49.36 remains historically elevated even after retreating from a 60.49 high, indicating unresolved volatility risk
- A 17.4M bbl crude stock build is not yet reflected in price action, creating a data gap between inventories and spot levels
- Net spec long positioning of 103,715 contracts leaves the market exposed to a reversal if length is unwound

## Outlook

Price action shows Brent and WTI holding gains near the top of their five-day ranges with volatility compressing from recent highs, but the reported crude stock build is not yet reflected in the positioning data. A continuation of net-long speculative exposure into the next CFTC report would confirm the current trend; a reduction would signal the inventory build is being priced in.
