Crude oil prices are sliding to four-month lows, and the United States Oil Fund (USO) is tracking that descent with unusual force. USO dropped 4.22% on Saturday, June 21, 2026, closing at 106.58 USD and sitting just above its 52-week floor of 105.65. The fund's 52-week high of 154.08 now looks distant, and the technical picture is unambiguous: an RSI of 27.46 places USO deep inside oversold territory.

The Strait of Hormuz Thaw Is Driving the Selloff
The immediate catalyst for crude's descent is diplomatic. Negotiations aimed at resolving the conflict between the United States, Israel, and Iran have gained visible traction, and traders are pricing in a reopening of oil flows through the Strait of Hormuz. Reports of tankers traversing the strait without interference from Iranian forces have compounded that optimism, and the market has repriced accordingly.
ING commodity analysts captured the mood in a note published June 21: "Positive signals from the Persian Gulf are fuelling optimism about oil flows through the Strait of Hormuz. Vessel crossings increased in recent days, although they remain well below pre-war levels." The qualification matters. Crossings are rising but have not normalized, which means any diplomatic reversal could quickly tighten the supply picture again.
A senior analyst at Mitsubishi UFJ Research and Consulting framed the dynamic directly, as quoted by Reuters: "Crude oil prices were weighed down by hopes of easing U.S.-Iran tensions and a recovery in oil shipments through the Strait of Hormuz." The operative word is "hopes." The market is trading on expectations, not yet on restored flow volumes that match pre-conflict levels.
Six Consecutive Weeks of Declining Pump Prices
Retail gasoline prices have now declined for six straight weeks in the United States, a streak that reflects the cascade from lower crude benchmarks into wholesale and then retail fuel markets. According to GasBuddy data cited by Reuters, the national average for a gallon of regular gasoline fell by 14.1 cents last week alone, landing at 3.85 USD per gallon as of Monday, June 16.
That is a meaningful move in a single week for a retail price that typically adjusts with a lag behind crude. The pace of the decline, however, has drawn attention from the White House. President Trump posted on social media that major oil companies are not passing through the full benefit of sharply lower crude costs to consumers at the pump. "The big Oil Companies are not dropping their price at the pump commensurate with the sharply lower prices they are paying for Oil," Trump wrote, characterizing the gap as gouging.
Trump followed that by announcing he had directed the Department of Justice to investigate immediately, adding: "Gasoline prices better start going down a lot faster than what I'm seeing." The announcement injects a regulatory variable into the downstream petroleum sector, even if the immediate market effect on crude itself is limited.
What the Numbers Say
USO's current positioning tells a stark story. The fund is trading at 106.58, just 93 cents above its 52-week low of 105.65, and 47.50 USD below the 52-week high of 154.08 reached earlier in the range. That high-to-low compression of roughly 31% over the trailing year reflects the full arc of the Iran-driven supply shock and its partial unwinding.
| Metric | Value | Implication |
|---|---|---|
| USO Price | 106.58 USD | Near 52-week floor |
| Daily Change | -4.22% | Sharp single-session selloff |
| 52-Week Range | 105.65 to 154.08 | Majority of range has been surrendered |
| RSI | 27.46 | Deep oversold, below 30 threshold |
| Brent Crude | 76.46 USD/bbl | Four-month low |
| WTI Crude | 72.61 USD/bbl | Four-month low |
The bull case from current levels rests almost entirely on mean reversion. An RSI below 30 has historically flagged exhausted selling in commodity ETFs, and with USO barely above its annual low, any deterioration in U.S.-Iran diplomacy or a fresh Hormuz incident could produce a rapid snapback. Supply disruptions in a chokepoint that carries roughly 20% of global seaborne oil remain a live risk.
The bear case, however, has real structural support. OPEC has been managing output with an eye toward price stability, but persistent demand softness in Europe and China could offset any supply-side tightening. The diplomatic optimism baked into current prices may be premature given that tanker crossings remain, by ING's own account, well below pre-war levels. If a final agreement on Hormuz passage takes longer than the market expects, prices could grind lower before stabilizing. A stronger U.S. dollar would amplify downward pressure on dollar-denominated crude benchmarks. The DOJ investigation into retail gasoline pricing adds an unpredictable political dimension to the downstream margin picture, though it does not directly alter crude supply and demand fundamentals.
Geopolitics as the Primary Variable
Oil markets spent much of the past year responding to the Iran conflict's effect on Hormuz transit. The current selloff is the mirror image of that earlier spike: traders are unwinding the risk premium that was built in when Iranian interference threatened to squeeze global supply. Brent at 76.46 and WTI at 72.61 represent a material retreat from the levels that prevailed when the chokepoint risk was at its peak.
The sequence matters analytically. Prices dropped, gasoline followed with a lag, and now the White House is pressuring the refining and retail chain to close what it characterizes as an unjustified margin gap. Whether or not the DOJ investigation uncovers actionable price-setting behavior, the political signal is clear: further retail price stickiness will face scrutiny. That dynamic could compress downstream margins even as crude softens.
Frequently Asked Questions
Why is USO falling so sharply right now?
USO tracks crude oil prices, which have dropped to four-month lows as optimism grows around a diplomatic resolution to the U.S.-Iran conflict and a partial resumption of tanker traffic through the Strait of Hormuz. The 4.22% single-session decline on June 21, 2026 reflects that geopolitical risk premium unwinding in real time.
What does an RSI of 27.46 mean for USO?
An RSI below 30 is conventionally read as oversold, meaning selling pressure has been unusually intense relative to recent price history. It does not guarantee a reversal, but it does indicate the fund is near a statistically extreme low on momentum indicators.
How does the Trump DOJ investigation affect crude oil prices?
The investigation targets retail gasoline pricing behavior by fuel stations and oil companies, not crude supply or production. Its direct effect on crude benchmark prices is limited, but it could constrain downstream margins if companies accelerate retail price cuts to avoid regulatory scrutiny.
Why haven't gasoline prices fallen as fast as crude oil?
Retail fuel prices typically adjust with a lag behind crude because the supply chain, refining capacity, wholesale distribution, and retail contracts all move on different timelines. The 14.1-cent weekly drop in the national average is actually a relatively sharp retail move, though the White House argues it remains insufficient given the pace of crude's decline.
Where Crude Prices Go From Here
USO at 106.58 with an RSI of 27.46 and 93 cents of cushion above its 52-week low is sitting at a technically fragile level. The next directional move will almost certainly be determined by the pace of diplomacy in the Persian Gulf. Confirmed, sustained increases in Hormuz tanker traffic toward pre-conflict volumes would validate the current repricing. A stall in negotiations, or any renewed Iranian interdiction, would likely snap the risk premium back into crude quickly. The DOJ investigation is a secondary variable, worth monitoring for its effect on downstream oil company margins rather than on the crude price itself.
