Oil Prices Sink as OPEC Production Surge Sparks Oversupply Fears

What to Know

• Crude oil prices dropped over 11% last week, settling near $65.50 — the largest weekly fall since the 2020 crash.
• OPEC+ ramped up output by 411,000 barrels per day (bpd) for July, with Kazakhstan’s overproduction adding unexpected supply.
• China’s oil demand growth has slowed to just 155,000 bpd as the economy pivots to EVs and rail freight, weighing heavily on global crude outlook.
• A sudden Israel-Iran ceasefire erased the geopolitical risk premium that had previously supported oil prices.
• Despite big U.S. inventory draws, oversupply concerns and weak refining margins continue to pressure prices lower.

Crude Oil Suffers Steepest Weekly Drop Since 2020

Crude oil futures plummeted 11.27% last week, marking the sharpest weekly decline since the historic 2020 collapse triggered by the pandemic lockdowns. Benchmark prices tumbled to $65.52 per barrel as a surge in OPEC+ production collided head-on with weakening demand forecasts and fading geopolitical tensions, shattering bullish market expectations for the summer.

The sudden collapse has revived concerns that the global oil market is entering a new phase of oversupply that could weigh on prices well into the second half of 2025, unless major producers reverse course or unexpected demand catalysts emerge.

OPEC+ Output Strategy Stuns Oil Markets

Traders had expected OPEC+ to stick with measured production adjustments through mid-2025 to keep the market tight. Instead, the alliance announced a combined increase of 411,000 bpd starting in July. Core producers such as Saudi Arabia and Russia are rolling back voluntary cuts totaling nearly 1 million bpd. This reversal comes as OPEC+ tries to maintain internal unity amid rising quota breaches.

Kazakhstan emerged as a major swing factor, producing 390,000 bpd above its quota thanks to higher output from the massive Tengiz field operated by Chevron. This pushed the nation’s total oil production to a record 1.86 million bpd, delivering a surprise supply boost that caught traders off guard.

The timing of the OPEC+ surge has raised concerns that the market may be overwhelmed with barrels just as consumption trends show signs of stagnating.

Demand Downgrades Add to Bearish Sentiment

At the same time, global oil demand growth is showing unmistakable signs of slowing. The International Energy Agency (IEA) cut its 2025 demand growth outlook to 720,000 bpd, while the U.S. Energy Information Administration (EIA) sees a slightly higher but still modest 800,000 bpd gain.

China’s demand, which has long been the engine of global oil consumption, is cooling more than many expected. Analysts now forecast China’s growth at just 155,000 bpd for 2025 — far below previous estimates — as electric vehicle adoption accelerates, rail freight expands, and heavy industry scales back output.

In the U.S., GDP growth projections have slipped to 1.4% amid tighter credit conditions and a Federal Reserve that remains cautious on rate cuts. With borrowing costs staying in the 4.25%–4.50% range, fuel demand growth is likely to remain soft for the rest of the year.

Together, these trends point to a demand backdrop that may not be able to absorb the flood of extra barrels hitting the market in the months ahead.

Ceasefire Between Israel and Iran Removes Risk Premium

A key factor that had supported oil prices through early June — geopolitical tension in the Middle East — has now faded dramatically. The unexpected ceasefire between Israel and Iran on June 24 effectively removed the estimated $10-per-barrel geopolitical premium that had bolstered crude during peak tensions.

This single event triggered a swift 6% daily price drop, sending shockwaves through energy markets. With oil flows through the Strait of Hormuz remaining steady and Iranian exports still near 1.7 million bpd, fears of a major supply disruption have evaporated, undermining one of the few remaining bullish arguments for oil prices.

U.S. Inventory Draws Offer Little Relief

On the supply side, U.S. stockpile data offered limited support to crude bulls. Despite a larger-than-expected 5.8 million barrel draw from commercial crude inventories and Cushing storage levels nearing operational minimums, refining activity remains muted.

Refinery utilization slipped to 86% last week, while gasoline crack spreads — a key measure of refinery profit margins — dropped below their five-year average. This indicates that refiners see little incentive to boost crude intake, further limiting any near-term upside for oil prices.

Short-Term Oil Outlook: More Pressure Ahead?

Looking forward, traders face a market shaped by multiple bearish forces. OPEC+ supply growth, non-OPEC production gains led by the U.S., Brazil, Canada, and Guyana, and tepid global demand all combine to create a strong oversupply narrative.

Seasonal hurricane risks could deliver short-lived spikes if Gulf production faces disruptions, but with the geopolitical premium gone and the demand side looking weak, sustained rallies appear unlikely for now.

Industry analysts warn that if supply continues to outpace demand growth, global oil inventories could begin to rebuild at a pace that pressures prices further into the low $60s range.

What Traders Should Watch Next

In the weeks ahead, oil market participants should monitor several key factors:

• Any signs that OPEC+ will reconsider its production plan if prices stay under $70 for an extended period.
• Whether Kazakhstan continues to exceed its quota, adding more barrels than anticipated.
• Updates on China’s fuel demand as EV sales and alternative transport infrastructure evolve.
• U.S. economic data and Federal Reserve policy shifts that could reshape the outlook for gasoline and diesel consumption.
• Hurricane season forecasts that could temporarily impact Gulf Coast supply.

Without a credible catalyst to tighten supply or surprise demand rebound, crude oil prices look set to stay under pressure well into the third quarter of 2025.
