# Brent-WTI Spread

By fxyz · https://f.xyz/t/43d7c566-25e0-4a2a-8558-7424747ba0bb

> The persistent spread between Brent and WTI crude can be exploited by going long the cheaper grade and short the expensive one, capturing mean-reversion when the differential widens beyond historical norms.

**Result:** If held over the last 3 months (Jul 13, 2026 – Oct 12, 2026): +0.9%. Over the same days: S&P 500 +3.5%, BTC +30.2%.

## What it holds

- **Core Spread Pair** (45%, −0.6% over 3 months): CL +24.0%, against BRENTOIL −30.7%
- **Energy Macro Hedge** (25%, +9.0% over 3 months): NATGAS +19.2%, HO −1.1%
- **Commodity Collateral** (15%, +2.8% over 3 months): GOLD +2.6%, SILVER +3.0%
- **Cash** (15%)

## The plan behind it

Brent typically trades at a premium to WTI due to its lighter quality and global pricing role, but the spread fluctuates with US inventory levels, pipeline constraints, and geopolitical risk. When Brent widens excessively vs WTI, shorting Brent and buying WTI captures the reversion; when WTI premium appears, the trade reverses. Cash is held to margin both legs and absorb volatility in the spread. Energy equities and macro hedges round out the portfolio to capture correlated themes.

**What would prove it wrong:** The Brent-WTI spread stabilizes structurally above $5 for more than 30 days with no reversion, indicating a regime shift in US export capacity or global supply dynamics that invalidates mean-reversion logic.

## FAQ

### Can I make one from my own idea?

Yes. Write what you believe in plain words at https://f.xyz/create. fxyz asks a couple of questions, builds the portfolio and shows how it would have done over the last 3 months.

### Can I turn a post on X into a theory?

Yes. Reply to the post and tag @fxyzai. It tests the view in the post and replies with the 3-month result and a link.

### What can it trade?

Stocks (Tesla, Apple, Nvidia), crypto (Bitcoin, Ethereum, Solana), pre-IPO companies (OpenAI, Anthropic), indices (Nasdaq 100, S&P 500), commodities (gold, silver, oil, copper) and currencies (EUR/USD, USD/JPY). One theory can mix them, and bet for or against any of them.

### How does it react to news?

On each check it reads the last two days of news on its biggest holdings and says whether the idea still holds. It can make one small change at a time: trim or drop one holding by up to 5 points. On autopilot the change waits 10 minutes so the owner can skip it; otherwise it asks first.

### How do I run it with real money?

For real money, tap Make it mine, open your copy and choose Use real money, with an exchange connected: Hyperliquid, Lighter, Lighter (Robinhood), Backpack, Pacifica or Binance. The money stays in your own account there. fxyz can place trades, but it can never withdraw.

### Can the AI get it wrong?

Yes. fxyz's AI turns the idea into holdings, and it can get that wrong: add a coin or stock that doesn't fit, or miss one that does. Check the holdings before you put money in. In your own copy, ask its chat to add or drop any of them.

### What do the 3-month numbers mean?

What $100 would have done holding this mix over the last 3 months, at real prices. It is a what-if, not a record: past or simulated results are no promise of future ones, and nothing here is investment advice.
