Why "The Tanks Haven't Run Dry" Is True and Wrong at the Same Time

In June, global oil inventories rose for the first time in four months. Read alongside the war in the Middle East, the effective closure of the Strait of Hormuz, and Brent crude trading near $94 a barrel, that number looks like a relief. The tanks, it appears, have not run dry.

The statement is true. It is also true in a way that should be a warning to an investor, not a reassurance.

The June climb came almost entirely from 117 million barrels of crude that shifted from storage on land onto tankers at sea. The onshore stocks — the barrels a refiner can actually call on the day a supply gap opens — kept falling, down roughly 96 million barrels from late February through May. Once you separate the barrels that are ready to use from the barrels that are just drifting offshore, the usable cushion is far thinner than the headline. The market has been absorbing the shock not by staying full, but by quietly draining its buffers.

The American numbers are sharper still. The Strategic Petroleum Reserve sits near 310 million barrels, down from around 700 million before the last drawdown program — the lowest it has been since 1983. In March, IEA member countries authorized the largest emergency release in history, 400 million barrels; by late July, 290 million of it had already been pumped out. When you read "inventories are resilient," what you are really reading is "we have used a lot of the shock absorbers."

Here is where it stops being a trivia question about tank levels and becomes an investment question. The same months that drained the buffers are the months the oil companies made record money on them. EOG Resources, one of the country's best-run shale producers, reported a record second quarter on the strength of the spike: roughly $2.7 billion of net income, or about $5.15 a share, and about $2.8 billion of free cash flow. On a trailing-twelve-month basis the company is generating roughly $13.4 billion in operating cash flow and about $6.6 billion of free cash flow, up around 46% a year, with just $3 billion of net debt against $32 billion of equity. Survival is not the issue with a balance sheet like that.

The issue is the price the market is now paying for that cash flow. The VanEck energy ETF, the broad basket most retail investors use to own the sector, is up roughly 45% this year and pressing its 52-week high. And EOG, on the surface, looks cheap: about 11 times trailing earnings and under 6 times trailing EBITDA, versus roughly 20 times and 10 times for ExxonMobil and 20 times and 8 times for Chevron. That discount to the majors is real, and it is exactly the kind of gap a value investor is trained to look at.

So why would a stock that just printed a record quarter and trades at half the multiple of the majors look "cheap" rather than "priced"? Because the cheapness is measured on twelve months of earnings that now include a price spike driven by a war. That is the whole crux of the argument over this market right now, and it is worth laying out plainly.

One side — including the firm whose quarterly commentary set off this line of thinking — argues the market is structurally tighter than it looks. The case is that years of underinvestment in upstream drilling have hollowed out the supply base, so that a geopolitical shock of this size hits a system that has too little spare capacity to spare. In that view, the spike is the floor, not the ceiling, and the price of oil has to climb well past $100 to fund the supply the world will need. The supporting data is not nothing: onshore stocks are at multi-decade lows, refineries are running near capacity, and the front months of the oil curve went sharply into backwardation, meaning barrels available right now are trading at a premium to barrels available in a few months — the signature of a market that is genuinely tight on prompt supply.

The other side is the base case from the authoritative forecaster. The U.S. Energy Information Administration expects the Hormuz production to return to near normal by early 2027 and forecasts Brent falling from around $85 this quarter to roughly $69 a barrel across 2027. In that version of the future, the spike is an event, not a regime, and it fades as the barrels come back.

Both can be partly right, and that is precisely what makes this a harder decision than the headline suggests. The structural case has a real mechanism behind it. But the dominant driver of the current $94 price is a war and a strait, not a change in how the world drills. If you believe the base case — that oil settles back toward $69 to $70 — then EOG's "record" quarter is a high-water mark, the trailing multiple stops being 11 times and starts being closer to what it was before the spike, and the stock that looks cheap on a $94 print looks a lot less cheap on a $70 print. The discount to the majors may not be a mispricing the market is too slow to fix; it may be the market being appropriately skeptical about how durable a commodity-fed earnings stream is.

That last point is the one a new investor should hold onto. This is a commodity business, and the entire cash-flow picture pivots on one number you do not control: the price of oil. A fee-based pipeline or midstream company earns its money whether oil is $60 or $110, which is why the durable, predictable cash flow deserves a different standard of scrutiny than a producer whose revenue is a line item of the Brent curve. EOG is the opposite — every dollar of that free cash flow is hostage to a price that the primary forecasters expect to fall.

So what does the evidence actually support? It supports the conclusion that the company is strong, the cash flow is strong, and the "tanks haven't run dry" story is technically accurate but misleading — it is describing barrels on tankers, not barrels you can actually draw on. What it does not yet support is the conclusion that the sector, up 45% and at its 52-week high, is cheap on a durable basis. The mispricing runs in both directions, and the only thing that breaks the tie is the path of the oil price, which is governed by a geopolitical event rather than by the balance sheet.

For an investor entering fresh, without a sharper read on how long Hormuz stays closed than the EIA has, paying up at the top of the spike is taking on event risk and calling it value. The thing to watch is not the inventory headline — which will keep being "resilient" for as long as barrels can be parked at sea — but whether Brent holds durably above the high $60s and low $70s as the production recovers. If it does, the structural bull has a point and the cheap-looking producer re-rates. If it fades toward $69, the record quarter was the peak, and the patience that keeps you out of a 45%-higher sector at its high turns out to have been worth more than the entry.
