XLE vs XOP comes down to this: XLE charges 0.08% and XOP charges 0.35%, and over the last 12 months the cheap fund won anyway. After WTI jumped 3.31% to $94.51 on September 8, 2026 on news that Iran’s Strait of Hormuz accord with Oman is near, energy ETF buyers are paying 4.4x more at XOP for a fund whose top 10 is mostly refiners.
What happened to oil on September 8, 2026?
Crude ripped higher on geopolitics, not demand. Yahoo Finance’s market blog put WTI at $94.51 a barrel on September 8, 2026, up $3.03 or 3.31%, with Brent creeping toward $100. Charles Schwab’s market update the same day showed WTI at $93.41 intraday, up 2.11%.
The catalyst was dated September 7, 2026. Iran said its accord with Oman covering traffic through the Strait of Hormuz was “in its final stages” and would include a temporary safe route, while warning that ships still face attack risk near Oman. Brent settled at roughly $97 on that Monday, up 1.13%.
Equities went the other way. Schwab’s September 8 numbers show the S&P 500 at 7,718.60, down 0.38%, with the 10-year Treasury yield at 4.77%. Energy is one of the few places money is working, which is exactly why the fee question matters now.
XLE vs XOP: what do the two funds actually own?
They are not two versions of the same trade. XLE is a 21-stock, cap-weighted slice of the S&P 500’s energy sector, dominated by two supermajors. XOP is a 51-stock modified equal-weight fund built from a broader industry index. One is a bet on Exxon and Chevron; the other spreads the same dollar across small caps.
What XLE holds
State Street’s fund page lists 21 holdings as of September 4, 2026, tracking the Energy Select Sector Index. ExxonMobil is 19.68% and Chevron 15.07% — 34.75% of the fund in two names. The top 10 accounts for 73.65% of assets.
That concentration is the product, not a flaw. If integrated majors lead an oil rally, XLE captures it directly. If they lag, there is nowhere to hide.
What XOP holds
XOP tracks the S&P Oil & Gas Exploration & Production Select Industry Index with 51 holdings as of September 4, 2026. Its largest position, PBF Energy, is 3.84%. The full top 10 adds up to just 30.79% — less than XLE’s top two.
Equal weighting hands small and mid caps the same dollar as the giants. That is the case for owning it, and it is also the source of the problem covered further down.
Which energy ETF has the lowest expense ratio?
XLE, at 0.08%. Vanguard’s VDE sits at 0.09%, and XOP charges 0.35% — 4.4 times XLE’s fee. On measurable cost, this is not close, and adding Vanguard to the comparison shows how far outside the cheap tier XOP sits.
| Metric | XLE | VDE | XOP |
|---|---|---|---|
| Gross expense ratio | 0.08% | 0.09% | 0.35% |
| Net assets | $42.11B | $10.93B | $4.04B |
| Holdings | 21 | 117 | 51 |
| Weighting | Cap-weighted | Cap-weighted | Modified equal weight |
| Index | Energy Select Sector | MSCI US IMI 25/50 Energy | S&P O&G E&P Select Industry |
| 30-day SEC yield | 2.34% | 2.21% (div. yield) | 1.58% |
| Inception | Dec 16, 1998 | Sep 23, 2004 | Jun 19, 2006 |

What a $10,000 position costs per year
Run the arithmetic on a $10,000 stake and the gap is small in year one and ugly over a decade. Fee is only half the story — the income difference is bigger than the fee difference.
- XLE: $10,000 × 0.08% = $8.00 a year in fees.
- VDE: $10,000 × 0.09% = $9.00 a year.
- XOP: $10,000 × 0.35% = $35.00 a year.
- Fee gap, XOP over XLE: $27 a year, or $270 over 10 years before compounding.
- Income gap: at the September 4, 2026 30-day SEC yields, $10,000 generates about $234 in XLE and $158 in XOP — a $76 difference.
- Combined: roughly $103 a year more in your pocket holding XLE, before any price difference.
Compounded, the fee alone bites harder than $270. Assume both funds return 8% gross for 10 years. XLE nets 7.92% and grows $10,000 to $21,429.86. XOP nets 7.65% and reaches $20,899.71. That is a $530.15 gap created by nothing but the expense ratio.
Does XOP’s higher fee buy higher returns?
Not over the last year. Through September 8, 2026, XLE returned 52.90% including dividends, VDE 52.45%, and XOP 49.15%. The most expensive fund of the three finished last. Investors paid 4.4x the fee for 3.75 percentage points less.
That is a reversal from earlier in 2026. According to etf.com’s March 26, 2026 flow review, XOP was up 47% year to date against 39% for XLE and VDE, while the S&P 500 was down 5%. Equal-weight E&P led when the rally started.
The lead did not hold. Big oil caught up: State Street reported XLE gained 7.4% in August 2026, the best of the 11 Select Sector SPDR funds. The higher-beta wrapper did not deliver a higher-beta outcome over the full 12 months.
Flows tell the same story. The same etf.com review counted about $13 billion into US-listed energy equity ETFs year to date, with $5.1 billion into XLE, roughly $1 billion into VDE and $745 million into XOP. Money went where the fee was lowest.
Is XOP really an exploration and production fund?
Only partly, and this is the most under-discussed thing about the product. Seven of XOP’s top 10 holdings as of September 4, 2026 are refiners and marketers, not drillers: PBF Energy, HF Sinclair, Marathon Petroleum, Delek US, Valero, Par Pacific and Calumet.
This is by design, not an error. S&P Dow Jones Indices states the underlying index draws from three GICS sub-industries: Integrated Oil & Gas, Oil & Gas Exploration & Production, and Oil & Gas Refining & Marketing.
Equal weighting then amplifies the smaller refiners into top slots. An investor buying XOP because crude is at $94 should know that refiners buy crude as an input. Rising feedstock costs and crack spreads drive their margins, not the barrel price alone.
If your thesis is “oil goes up, so producers earn more,” XOP’s ticker name is a poor description of what you are buying today. That is a labeling problem worth pricing into the 0.35%.
How much does liquidity cost you?
XLE trades in a different league. At the September 8, 2026 close of $64.77 and average volume of 28.1 million shares, XLE turns over roughly $1.82 billion a day. XOP, at $190.71 and 1.51 million shares, does about $288 million — 6.3 times less.
VDE is the thinnest of the three despite $10.93 billion in assets, at roughly $135 million a day on 741,087 shares. For a retail-sized order none of this is decisive, but it sets the spread you pay on entry and exit.
The scale gap is structural. XLE holds $42.11 billion against XOP’s $4.04 billion as of September 4, 2026. Bigger funds hold tighter spreads, and spread is a real cost that never appears in the expense ratio. The same dynamic drives our breakdown of SPY vs VOO vs IVV, where liquidity and fee point in opposite directions.
Which energy ETF fits which investor?
Match the wrapper to the thesis. If you want supermajor cash flows and dividends, the cheap cap-weighted funds do it. If you specifically want small-cap producer torque, XOP is the only one of the three that delivers it — at a price.
| Investor goal | Best fit on measurable attributes | Why |
|---|---|---|
| Lowest annual cost | XLE (0.08%) | $8 a year per $10,000 vs $35 for XOP |
| Highest income | XLE (2.34% 30-day SEC yield) | $76 more per $10,000 than XOP |
| Broadest energy exposure | VDE (117 holdings) | Includes mid and small caps XLE omits, at 0.09% |
| Least single-stock risk | XOP (top 10 = 30.79%) | XLE puts 34.75% in two names |
| Tightest trading costs | XLE (~$1.82B daily volume) | 6.3x XOP’s dollar turnover |
| Pure small-cap producer beta | XOP | Only equal-weight option — but 7 of top 10 are refiners |
Sector timing carries its own risk. Energy leadership in 2026 has been driven by geopolitics — the Hormuz story, Saudi facility attacks — not by a demand cycle. Headlines that gap oil up can gap it down. For context on how macro rate moves hit fund pricing, see our look at what a 25 basis point Fed hike costs bond ETF holders.
Frequently asked questions
Is XLE or XOP cheaper to hold?
XLE, by a wide margin. Its gross expense ratio is 0.08% versus 0.35% for XOP, per State Street’s fund pages. On $10,000 that is $8 a year against $35.
Why does XOP hold refiners?
Because its index includes them. S&P Dow Jones Indices defines the S&P Oil & Gas Exploration & Production Select Industry Index across three GICS sub-industries, including Oil & Gas Refining & Marketing.
Which energy ETF pays the higher yield?
XLE. Its 30-day SEC yield was 2.34% as of September 4, 2026, against 1.58% for XOP. VDE’s dividend yield was 2.21% as of September 8, 2026.
Is XLE too concentrated?
It depends on your tolerance for two-stock risk. ExxonMobil and Chevron together were 34.75% of XLE as of September 4, 2026, and the top 10 was 73.65%. VDE spreads the same sector across 117 names for one extra basis point.
Did XOP beat XLE in 2026?
Early on, yes. etf.com reported on March 26, 2026 that XOP was up 47% year to date versus 39% for XLE. Over the trailing 12 months to September 8, 2026, XLE led at 52.90% against XOP’s 49.15%.
What drove the September 2026 oil move?
Iran’s statement on September 7, 2026 that its Strait of Hormuz accord with Oman was in final stages, alongside warnings of attack risk near Oman. WTI rose 3.31% to $94.51 on September 8, 2026.
Are energy ETF flows following performance?
They are following fees. Of roughly $13 billion into US-listed energy equity ETFs year to date as of etf.com’s March 26, 2026 count, $5.1 billion went to XLE and $745 million to XOP.
The bottom line
On every attribute you can measure, XLE beats XOP: lower fee, higher yield, deeper liquidity, better trailing 12-month return. XOP wins on exactly one thing — it does not put a third of your money in two stocks.
So the answer is not “it depends.” It depends on precisely one question: whether you are buying energy or buying small-cap producers. If it is energy, the 0.08% fund is the better-built product and the extra $27 a year buys you nothing you can point to.
If it is small-cap producer torque, check the holdings sheet before you pay for it. Seven of XOP’s top 10 refine crude rather than pull it out of the ground, which is not what the ticker advertises.
