EIA Refining Report: How to Trade Utilization & Inventories

Every Wednesday at 10:30 am ET, the U.S. Energy Information Administration (EIA) drops its Weekly Petroleum Status Report. If you trade crude oil or refined products, you know this report can send prices swinging in minutes. But while everyone obsesses over the headline crude inventory number, the refining data — especially refinery utilization rates — often gets ignored. That's a mistake. In my decade-plus of trading energy futures, the refining numbers have given me more of an edge than any headline stock figure ever could.

Here's the thing: refinery utilization tells you how much crude oil the U.S. is actually processing. That's a direct read on demand. It also shows how much gasoline and diesel we're making, which drives crack spreads and product prices. So, if you want to understand the oil market beyond the weekly noise, you need to dig into this data. Let me walk you through it.

What is the EIA Refining Report?

The Weekly Petroleum Status Report (WPSR) is the EIA's flagship data release. It's published every Wednesday (except holidays) and gives a snapshot of the previous week's energy supply chain. The refining section specifically breaks down three critical things:

• Refinery utilization rate — the percentage of operable refining capacity being used
• Crude oil inputs — the total volume of crude processed (in millions of barrels per day)
• Product outputs — how much gasoline, distillate, and other products were manufactured

Here's a quick reference table to help you understand the key metrics:

Most people only look at crude inventories. But the refining data inside the same report is often the real mover if you know how to read it.

Why Refinery Utilization Rate Matters for Oil Prices

Refinery utilization is a proxy for crude oil demand. When refineries run at higher rates, they're pulling crude from storage and buying more barrels from producers. That's supportive for crude prices. Simple enough, right? But there's a second layer: high utilization also means more gasoline and distillate supply, which can pressure product prices and squeeze refiners' margins. So, the net market impact is rarely one-sided.

I've seen dozens of trading cycles where crude rallied on high utilization, only to crash two weeks later when product inventories ballooned. The key is to look at utilization in context. For example:

• If utilization spikes to 95%+ outside of peak season, it signals aggressive crude demand — bullish for WTI or Brent.
• If utilization is high and gasoline stocks are building, expect crack spreads to weaken.
• If utilization drops sharply, crude demand may be soft, but maintenance could be the reason — not actual demand weakness.

Seasonality plays a huge part here. Refineries typically crank up in March and April to prepare for summer driving season. Then they often undergo maintenance in September and October. A utilization rate of 90% in February is very different from 90% in May.

How to Interpret EIA Refining Data

What is a 'Normal' Refinery Utilization Rate?

There's no universal 'normal,' but U.S. utilization typically swings between 85% and 95%. During spring maintenance, it can dip below 85%. In peak summer, it often hits 95–96%. Some Gulf Coast mega-refineries can run above 100% for short periods if they're pushing beyond nameplate capacity, but that's rare.

The bigger mistake I see traders make is reacting to a weekly change without adjusting for season. A jump from 88% to 92% in April is bullish, but the same jump in July is just noise — you're already near max capacity.

Seasonal Patterns in Refinery Utilization

U.S. refineries follow a fairly predictable calendar:

• February–March: Winter maintenance, utilization often drops to 80–85%.
• April–June: Ramp up for summer gasoline, utilization climbs toward 93–95%.
• July–September: Peak summer, utilization stays high unless there's a hurricane or outage.
• October–November: Fall maintenance, utilization drops again.
• December–January: Moderate winter runs, utilization around 85–90%.

Understanding these cycles helps you separate real demand signals from normal operational shifts.

Linking Utilization with Storage Data

The magic happens when you combine utilization with inventory changes. In the simplest scenario:

• High utilization + large crude draw = strong demand, bullish for crude.
• Low utilization + crude build = weak demand, bearish for crude.
• High utilization + gasoline build = oversupplied products, bearish for RBOB and crack spreads.

But be careful: high utilization without a crude drop might mean imports are flooding in. Or it could mean the EIA revised the previous week's number. Always look at the actual crude runs, not just the percentage.

EIA Refining vs. API Report: Which One Moves Markets?

Every Tuesday at 4:30 PM ET, the American Petroleum Institute (API) publishes its own inventory report. Many retail traders use the API as a 'sneak peek' at the EIA data. But here's where I get controversial: I think the API report is overhyped and often misleading. It's a private industry survey, not a government census. The EIA data is far more complete and reliable.

I've personally traded both reports for years. There are times when the API shows a massive crude draw, but the EIA releases a build — and the market reverses hard. In one scenario last spring, the API pushed futures down 2%, but the EIA numbers confirmed a surprise draw, and prices bounced right back. If you exited on the API signal, you lost money.

So, my rule: never trade on the API alone. Wait for the EIA confirmation, or at least wait 20 minutes after the EIA release to let the initial volatility settle.

Trading Strategies Using EIA Refining Data

The Refinery Utilization Trade

This is my favorite play. When the EIA reports utilization significantly above the five-year average, it tells me that refiners are aggressively buying crude. That's a bullish signal for crude prices, especially if it's happening during a season when utilization usually lags.

For example, if utilization jumps from 85% to 91% in mid-October, a time when maintenance is typical, that's a serious upside surprise. I'll look to buy crude futures or calls. Conversely, a utilization drop in April when it should be rising is bearish — I might short or buy puts.

Using Product Inventory Data

Sometimes the crude numbers are muted, but product inventories tell a cleaner story. During summer, if gasoline inventories draw down even with utilization at 95%, that signals massive demand. RBOB futures often spike. I remember a holiday week when the EIA reported a huge gasoline draw because people drove more than expected. The crack spread widened sharply, and anyone who traded that move cleaned up.

Calendar Spreads

Refining data also affects calendar spreads. If utilization is high now but expected to drop due to maintenance next month, the front-month crude might rally relative to the second month. I've used this to trade the spread between consecutive WTI contracts by watching the EIA's utilization trends over several weeks.

Common Mistakes When Trading EIA Refining Data

Over the years, I've seen traders blow up accounts by making these five mistakes:

1. Ignoring seasonal norms. A utilization spike in September is not the same as one in April. Always compare to the 5-year average.
2. Overreacting to the API report. The API is a rough estimate, not the official government data. Wait for the EIA.
3. Treating high utilization as always bullish. If utilization is already at 96%, there's little room to grow. The market may 'sell the news' because the demand is already priced in.
4. Forgetting about product exports. The U.S. exports a huge amount of gasoline and diesel. High utilization might be for export demand, not domestic consumption. In that case, product inventory builds abroad can eventually drag prices.
5. Not using a two-week average. Weekly data can be distorted by weather, outages, or holidays. I always look at the 2-week moving average of crude inputs to filter the noise.
