- WTI: support 77.78, resistance 86.87

## Price Action & Technicals

> Crude benchmarks rose on the week while gasoline fell and implied volatility stayed near its recent highs.

Brent settled at **$90.12**, up **1.99%** over the five-session window, having traded across a wide **$82.51–$93.89** range. WTI closed at **$84.67**, up **2.49%**, with a comparable **$77.78–$86.87** range. Both benchmarks are trading in the upper half of their five-day ranges, consistent with the positive weekly change.

Refined products diverged from crude: RBOB gasoline fell **3.18%** to **$3.22**, while heating oil was roughly flat (**+0.24%**) at **$4.12**. This crude-vs-product split is visible directly in the price data but is not explained by any inventory or positioning figure in this package.

The Crude Oil VIX (OVX) rose **3.99%** to **63.04**, sitting near the top of its **54.94–70.16** five-day range — implied volatility remains elevated relative to the recent window even as spot prices advanced.

## Supply & Inventories

> Crude stocks built by 2.5M bbl even as refiners ran at 96.5% utilization.

EIA data for the period show crude stocks at **407.0M bbl**, a weekly build of **+2.5M bbl**. Production held at **13.80M b/d** and imports at **6.20M b/d**, while refinery utilization stood at a high **96.5%**.

The combination of a stock build alongside near-record refinery utilization indicates that crude inflows (production plus imports) outpaced the already-high rate of refinery draw during the period.

## Positioning & Flows

> Speculative positioning remains net long by more than 2:1, consistent with the week's price advance.

CFTC data as of 2026-07-28 show money managers holding **195,035** long contracts against **86,728** short, for a net speculative long of **108,307**. Open interest stood at **2,534,800** contracts, putting the long/short ratio at roughly **2.25:1**.

This skew toward net length aligns directionally with the week's price gains in both Brent and WTI, though the dataset does not indicate whether positioning was added or trimmed relative to the prior report.

## Macro & Cross-Asset

> Crude gained on the week even with a firm dollar index and elevated yields, a relationship not clarified by this dataset.

The US Dollar Index stood at **119.70** on 2026-07-31, alongside a 10-Year Treasury yield of **4.75%** and a Fed Funds rate of **3.63%**. CPI was last reported at **332.813**.

Crude prices rose over the window despite the elevated dollar index level; this divergence is not explained by the dollar or rate data in this dataset and should be treated as an open item rather than attributed to a specific driver.

## What to watch

- Crude stocks building (+2.5M bbl) despite 96.5% refinery utilization
- OVX near the top of its five-day range at 63.04
- RBOB down 3.18% while crude benchmarks gained, a crack-spread divergence
- Net spec long at 108,307 contracts against 2.53M total open interest
- Brent and WTI both trading in upper half of five-day ranges

## Risks to the view

- Elevated OVX (63.04, near 70.16 five-day high) signals continued implied volatility risk
- Net speculative long positioning (~2.25:1 long/short) leaves crude exposed to unwind risk
- Crude stock build alongside high refinery utilization suggests inventory data could turn choppy in coming weeks

## Outlook

With Brent and WTI holding in the upper half of their five-day ranges, near-term technical support sits at $82.51 and $77.78 respectively, with resistance at the recent highs of $93.89 and $86.87. Elevated OVX readings and a net-long speculative positioning skew suggest the market is vulnerable to sharp moves in either direction on the next data print.
