A Simple Brent-WTI Spread Idea

The basic idea

One simple trade idea I have been thinking about recently is going long the Brent-WTI spread.

Why? First, if you look at the past few weeks, or from the start of the war until now, oil prices have generally stayed below 100. You can clearly see active government intervention. But you still do not really know whether the war will continue, or whether oil will go up or down outright. In that kind of situation, one relatively stable approach is not to use a traditional futures contract for a pure directional bet. You can express the view through a DeFi exchange instead, because the pricing tracks in real time.

Why Brent normally trades above WTI

The logic is simple. Under normal conditions, Brent is usually more expensive than WTI. The historical range for the spread is roughly 2 to 6 dollars, depending on the period. A spread near 2 is at the low end.

Why does that spread exist? Brent is more closely tied to international usage, while WTI is delivered locally in the United States. Freight costs, premiums, and quality differences are not the same. So normally, Brent should trade at some premium to WTI.

At the beginning of the war, we saw an extreme case where Brent traded about 11 dollars above WTI. The most unusual case was when WTI traded 4 to 5 dollars above Brent. Why did that happen? The first reason is delivery timing. WTI was delivered earlier than Brent, and the market at that moment was dealing with spot shortage.

If you look at the past few weeks of SPR releases, you can see that in many cases the U.S. has used massive exports to pressure Brent prices lower, while WTI stayed relatively higher. Local supply was effectively being converted into global supply.

The setup

Now the spread is very low, generally around 2 dollars or even below 2. I think there are two main scenarios.

First, the war continues, or oil remains genuinely short. In that case, after SPR releases run for a while, maybe after this month, as Chevron's CEO suggested, oil prices may become much harder to manage through intervention. The real active shortage would show up, and Brent could move toward 102 or 103. At that point, the spread should also widen. On top of that, because there have already been so many SPR releases, there is a real possibility that Trump could ban crude oil exports, or perhaps refined-product exports. If something like that happens, the gap could widen further.

Second, even if the war ends, the trade can still become a mean-reversion idea. If the spread moves from the low end around 2 dollars back toward the normal 3 to 4 dollar range, that is still roughly a 50% to 100% return on the spread.

Entry and exit

In practical terms, my entry would be when the Brent-WTI spread is below 2 dollars. That is the zone where I would want to be long the spread. For exit, I would look to take profit when the spread moves back toward 4 dollars, and I would be much more willing to fully exit if it reaches 6 dollars.

Risks

So what are the risks in this trade?

The first risk is entry price and leverage. If you enter too early or with too much leverage, you could be liquidated. In an extreme case, WTI could trade above Brent by enough to exceed your maintenance margin. That scenario has to be considered.

The second risk is instrument choice. It is difficult to express this cleanly with a standard futures-contract trade because the timing is uncertain. You may have to use perpetual futures instead. Funding rate then becomes a very different issue. You might have to pay funding on the WTI short, and depending on market conditions, you could also face funding pressure on the Brent leg. If funding becomes too expensive, the trade may no longer be worth it.

Overall, though, I still think the risk-reward looks pretty good.
