# Iran's oil keeps flowing, sanctions or not

By @shanaka86 on X · https://f.xyz/t/9baed56a-70df-4328-b988-0e65a39643f0

> Western refineries cannot easily replace Iranian light crude, so sanctions will keep leaking and Iranian barrels will keep reaching the market for years.

**Result:** If held over the last 3 months (Jul 22, 2026 – Oct 21, 2026): +12.0%. Over the same days: S&P 500 +3.0%, Gold +0.9%.

## What it holds

- **Crude itself** (43%, +13.6% over 3 months): BRENTOIL (Brent crude oil) +18.6%, CL (WTI crude oil) +16.0%, HO (Heating oil) +2.3%
- **Oil producers** (30%, +12.2% over 3 months): XLE (Energy Select Sector fund) +15.9%, CVX (Chevron) +7.6%
- **Hedge on easy times** (13%, +2.6% over 3 months): against TLT (Long-term Treasury bond fund) +2.2%, against JPY (Japanese yen) +3.1%
- **Cash** (15%)

## The plan behind it

If Iranian oil is hard to replace, then oil prices stay supported and sanctions do not cut supply the way headlines suggest. The first group owns oil itself, which gains when buyers keep needing those barrels. The second group owns big oil producers, which earn more when crude stays firm. The third group is a small short on the idea that sanctions work and that growth stays cheap and easy. Cash is there in case sanctions suddenly get enforced and prices jump, or an easy deal sends oil down and we need room to change.

> Everyone talks about Iranian oil in barrels. Nobody talks about what is inside them. That difference is why Western refineries have been running shadow networks through Dubai for twenty years to get it despite the sanctions.

> Crude oil is not a uniform commodity. It is a spectrum of hydrocarbons with different molecular weights, and the composition of a given crude determines how easily it converts into the products refineries actually want to sell: gasoline, diesel, jet fuel, heating oil. The measurement that captures this is API gravity. Higher API gravity means lighter crude with shorter carbon chains, which means lower energy cost to crack, lower processing cost to refine, and higher yield of the light distillates that carry premium pricing. Lower API gravity means heavier crude requiring more energy, more processing steps, more capital equipment, and producing a higher share of lower-value residuals.

> Iranian Light crude runs at 33 to 36 degrees API gravity with sulfur content between 1.36 and 1.5 percent. That is the refinery sweet spot. It is light enough to yield high fractions of gasoline and middle distillates without excessive processing costs, but heavy enough to produce the full range of products that complex refineries are designed to process. It is what petroleum engineers call an optimal blend crude.

> Venezuelan Merey heavy crude runs at approximately 16 degrees API gravity with sulfur between 3 and 5 percent. Refining it profitably requires a coking unit, a hydrocracker, and an extensive desulfurization train. The equipment exists. The economics work for refineries purpose-built around Venezuelan feedstock. It is not a substitute for Iranian crude. It is a different product requiring different industrial infrastructure.

> US West Texas Intermediate runs at 39 to 40 degrees API with sulfur below 0.25 percent. In theory, the cleanest and easiest crude to process. In practice, it is so light that it does not yield the heav

**What would prove it wrong:** Exit if Western refiners show they can swap out Iranian-style crude easily, or if sanctions are truly enforced and oil prices still fall.

## 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.
