Lowest Spread Oil Trading Brokers — WTI & Brent Crude Data

Crude oil is the third most traded commodity CFD after gold and EUR/USD, and its spread structure is fundamentally different from both. While forex spreads are measured in tenths of a pip and gold in cents, oil spreads are measured in cents per barrel — and the relationship between spread, contract size, and dollar impact confuses many traders. A 3-cent spread on WTI might sound tiny, but on a standard oil lot (1,000 barrels), that is $30 per round-trip.

We tracked WTI (US Crude) and Brent (UK Crude) spreads for 30 days across Exness, IC Markets, Pepperstone, and XM on their respective raw/tight accounts. Here is the data.

Understanding Oil Spread Costs

Before diving into the data, a quick primer on how oil spreads translate to actual costs. Most brokers quote oil in dollars per barrel with a standard lot of 100 or 1,000 barrels (this varies by broker and platform):

• Exness: 1 lot = 100 barrels. A 3-cent spread = $3.00 per lot.
• IC Markets: 1 lot = 1,000 barrels. A 3-cent spread = $30.00 per lot.
• Pepperstone: 1 lot = 100 barrels (MT5) or varies by platform.
• XM: 1 lot = 100 barrels. A 5-cent spread = $5.00 per lot.

Contract sizes differ between brokers. Always check your broker's contract specifications before comparing — a "3-cent spread" costs 10x more at IC Markets than at Exness because of the different lot sizes. We normalize all comparisons below to a per-barrel basis to ensure fair comparison.

WTI Crude Oil (US Oil) Spread Data

Exness delivers the tightest WTI spreads across all sessions. The 3-cent average during US hours represents just 0.04% of the barrel price — remarkably tight for a commodity CFD. IC Markets is a close second at 4 cents, while XM trails at 5 cents.

The Asian session widening (7-10 cents) is dramatic across all brokers because NYMEX futures, which provide the primary pricing reference for WTI CFDs, are in their overnight session with reduced volume. If you trade WTI from Asian timezones, accept approximately 2x the spread cost compared to US hours.

Brent Crude Oil (UK Oil) Spread Data

Brent spreads are approximately 0.5-1 cent wider than WTI across all brokers. This reflects Brent's slightly lower CFD trading volume (WTI is the more popular benchmark among retail traders despite Brent being the global pricing reference). Brent spreads are tightest during London hours rather than US hours because ICE Futures Europe, which hosts the Brent contract, is London-based.

Annual Cost Impact for Oil Traders

For a trader executing 5 standard lots of WTI per day (normalized to Exness lot size of 100 barrels), 20 trading days per month:

An important nuance emerges here: XM's Ultra Low account charges no commission on oil, only the spread. Despite having the widest spread (5 cents), the absence of a $7 commission makes it the cheapest overall for oil trading. This is the opposite of forex, where commission accounts almost always win.

For oil-focused traders, XM Ultra Low's total cost of $5.00 per 100-barrel lot undercuts Exness's $10.00 by half. This is a significant finding that contradicts the "Exness is always cheapest" narrative we see in forex comparisons. The lesson: optimal broker choice depends on the instruments you trade, not just headline EUR/USD spreads. See our index spread comparison for similar analysis on stock indices.

Oil Spread Spikes: EIA and OPEC Events

Oil is more event-sensitive than most forex pairs. Two recurring events cause predictable spread spikes:

EIA Crude Oil Inventory Report (Weekly)

Released every Wednesday at 14:30 UTC (10:30 AM Eastern). This is the single most impactful recurring event for oil traders. Spreads typically spike to 15-25 cents in the first 10-15 seconds after release, then recover to below 5 cents within 60-90 seconds. The magnitude of the spike correlates with how much the actual inventory change deviates from the forecast.

OPEC+ Meetings (Periodic)

OPEC+ production decisions can move oil 3-8% in a session. During the December 2025 OPEC+ meeting, WTI spreads on Exness hit 45 cents — approximately 15x the normal level — and remained above 10 cents for 20 minutes. If you trade through OPEC events, use wide stops and expect significant execution uncertainty.

Oil vs Gold vs EUR/USD: Spread Cost Comparison

How does oil spread cost compare to other popular instruments on the same accounts?

Oil is approximately twice as expensive to trade as EUR/USD or gold in percentage terms — but significantly cheaper than crypto CFDs. For cost-sensitive traders who regularly trade oil alongside forex, the instrument-specific cost differences should influence position sizing and profit targets. See our gold spread comparison for the precious metals angle.

Our Recommendation for Oil Traders

If you trade oil exclusively or primarily, XM Ultra Low is the cheapest option due to zero commission, despite wider spreads. The $5 total cost per 100-barrel lot is unmatched.

If you trade oil alongside forex and want one account for everything, Exness Raw Spread offers the tightest oil spreads and the best forex spreads — but the $7 commission pushes total oil cost to $10 per lot.

If you trade through OPEC and EIA events, Exness's faster spread recovery gives a practical advantage over XM for event-driven strategies.
