Hello, this is Daily Stock, closely analyzing the global commodity market and macroeconomic trends to deliver prompt and accurate information to investors.
Executive Summary
[Image: /stdaily/uploads/202607/gen_6a480f5d06cce9.43200982.png]
According to a recent announcement by the U.S. Energy Information Administration (EIA), U.S. commercial crude oil inventories have fallen to 408.4 million barrels, the lowest level since 2018 (about an eight-year low), showing a tightening of supply in the commodity market.
While refinery utilization rates continue to hover at a high of 96.6%, gasoline inventories also decreased, demonstrating strong demand during the summer peak driving season.
Amidst a decoupling of monetary policies and economic fundamentals across three major global regions (the U.S., Europe, and Asia), this sharp drop in inventories is interpreted as a key supply-side factor supporting West Texas Intermediate (WTI) crude oil prices.
At a time when easing geopolitical risks and seasonal peak demand coexist, we closely analyzed structural changes in the global energy supply chain and the resulting scenarios for crude oil asset volatility.
Current Status Summary
According to the recently released weekly crude oil inventory report, U.S. commercial crude oil inventories (excluding the Strategic Petroleum Reserve, or SPR) fell by 3.775 million barrels from the previous week to 408.4 million barrels.
Although this fell short of the market's average estimate of a roughly 5.1 million-barrel draw, it is the lowest absolute volume since September 2018.
In particular, total U.S. inventories including the SPR have plummeted by approximately 120.71 million barrels since Middle East tensions began to escalate, reaching about 734 million barrels, the lowest level since May 1984.
Deliveries hub inventories in Cushing, Oklahoma, rose by 709,000 barrels from the previous week, halting a nine-week streak of declines, but still remain near the lower operational limit.
Meanwhile, global stock markets are seeking direction while experiencing stark volatility across asset classes.
As of the close on July 4, 2026, the KOSPI stood at 8088.34, the KOSDAQ at 868.41, the Nasdaq Index at 25832.67, and the USD/KRW exchange rate at 1530.60, indicating significantly dampened investor sentiment.
According to Daily Stock's own Fear and Greed Index, the KOSPI is currently in the "Fear (21.2)" stage, maintaining a level similar to one month ago (21.6).
The Nasdaq is also in the "Fear (31.9)" stage, a sharp deterioration from the "Greed (77.6)" stage seen three months ago.
Financial Analysis
Looking at the trends in commercial crude oil inventories and detailed supply-demand data for petroleum products like gasoline and distillates, the extreme high-load operation of the refining industry is clearly visible.
U.S. refineries' crude oil input averaged 17.2 million barrels per day, and refinery operating utilization rates continued to record an extremely high level of 96.6%.
| Category | Recent Release (Week of June 26) | Market Forecast | Change from Previous Week | Level Compared to 5-Year Average |
|---|---|---|---|---|
| Commercial Crude Inventories | 408.4M barrels | -5.1M barrels | -3.775M barrels | Approx. 7% lower |
| Gasoline Inventories | 214.0M barrels | -950K barrels | -2.333M barrels | Approx. 7% lower |
| Distillate (Diesel, Heating Oil) | 108.6M barrels | -700K barrels | +2.483M barrels | Approx. 8% lower |
| Cushing Hub Inventories | Around 20.7M barrels | - | +709K barrels | Close to min. operating level |
| Refinery Utilization Rate | 96.6% | - | +0.5%p | Top tier high run |
Despite the high refinery utilization rate, the 2.333 million-barrel draw in gasoline inventories proves that gasoline consumption for the U.S. Independence Day holiday weekend exceeded market expectations.
In contrast, distillate inventories including diesel and heating oil rose by 2.483 million barrels, showing a relatively moderate supply-demand balance for industrial energy.
Valuation
The technical valuation of WTI crude oil currently stands on the equilibrium of opposing momentums: seasonal peak demand and the partial dissipation of the geopolitical risk premium.
Over the past 10 years, oil prices in July have averaged a solid 2.2% increase due to the onset of the summer driving season, supporting the lower bound of valuation.

Furthermore, the Baker Hughes drilling rig count—a leading indicator of U.S. crude oil production—has recorded declines for three consecutive weeks, with tight supply conditions providing a floor for prices.
However, with the possibility of an interim agreement between the U.S. and Iran aimed at easing Middle East conflicts, the risk premium has adjusted significantly compared to when oil prices neared $100 per barrel in the past.
Liquidity in the broader commodity market is reflected in valuation, intricately intertwined with the hawkish monetary policies of global central banks.
The U.S. Federal Reserve's stance of keeping high interest rates for longer, which props up the U.S. Dollar Index, acts as an upper resistance line limiting any aggressive upward breakouts in WTI valuation.
Expert & Institutional Analysis
Foreign financial institutions and commodity analysts estimate that this inventory draw demonstrates the tight physical supply-demand resilience of the U.S., rather than a short-term supply-demand distortion.
Even with refinery operating rates nearing 96.6%, commercial inventories are more than 7% below the five-year average, prompting a consensus that supply-demand tightness will not easily ease until the autumn maintenance season.
On the other hand, from a medium- to long-term perspective, some institutional forecasts view the 2026 oil market as an extension of a bear market dominated by oversupply.
Major domestic and international institutions, such as the Korea Center for International Finance (KCIF), explain that oil prices could gently stabilize downward if steady production increase efforts from non-OPEC+ countries continue and the geopolitical conflict-easing agreement between the U.S. and Iran is finalized.
In particular, the varying economic recovery strengths of Europe and Asia represent a complex variable.
While the Eurozone Composite PMI rebounded to 50.0 in June, barely escaping contraction territory, China’s Caixin/RatingDog Services PMI printed a robust expansion at 54.1, showing differing paces of demand recovery across regions.
Risk Factors
The most concerning risk factor is the stark economic and monetary policy "tri-polar decoupling" among major global regions.
Unlike the U.S. Federal Reserve, which is treading a cautious path by holding interest rates steady for a long period, the European Central Bank (ECB) made a surprise rate hike in June to 2.25% to pre-emptively defend against inflation triggered by oil price shocks from the Middle East conflict.
The Bank of Japan (BOJ) also raised its benchmark rate to 1.0% at its June monetary policy meeting to counter import price pressures, sparking a monetary tightening normalization.
This breakdown in monetary policy coordination among major nations shakes the risk-free return of financial assets, and is highly likely to suppress capital inflows into physical commodities like crude oil.
Another potential risk is a secondary supply shock scenario if the agreement to reopen the Strait of Hormuz between the U.S. and Iran gets canceled or delayed due to unexpected variables.
The fact that U.S. shale drillers are taking a passive approach to boosting production by cutting back on exploration and new drilling investment also means their ability to cover sudden supply shortages is significantly lower than in the past.
Investment Outlook Summary
U.S. commercial crude oil inventories reaching their lowest level in eight years, combined with robust peak summer gasoline demand, appear sufficient to serve as a strong support floor for oil prices in the short term.
While the high utilization rates of U.S. refineries will attract oil buying for now, scheduled autumn maintenance is on the horizon, presenting both potential volume buildup and price corrections after mid-Q3.
Therefore, rather than betting on aggressive price gains, a rational investment perspective suggests focusing on a rangebound volatility scenario where WTI prices oscillate between $75 and $85 per barrel, utilizing seasonal demand support levels.
At the same time, maintaining a risk-off posture in portfolios while closely watching the progress of geopolitical negotiations and the timing of replenishing the SPR (which is at historic lows) appears to be an effective strategy.
This is a time to continuously monitor how fundamental discrepancies between the U.S., Europe, and Asia impact physical assets and currency values.
Investor Checklist Q&A
Q1. What is the direct cause of U.S. crude oil inventories hitting an eight-year low?
A1. With driving demand surging during the U.S. Independence Day holiday and summer vacation season, refineries maximized their utilization rates up to 96.6% to process and consume large amounts of crude oil.
Q2. Why are prices holding up firmly even though the inventory draw was smaller than market expectations?
A2. Although it fell short of some aggressive draw projections, the absolute volume of commercial crude oil inventories reached a tight level of 408.4 million barrels, proving a tight supply-demand state that is approximately 7% lower than the five-year average.
Q3. Why is it important that the U.S. Strategic Petroleum Reserve (SPR) has fallen to historic lows?
A3. It means that the total U.S. crude oil volume (commercial inventory + SPR) has plunged to 734 million barrels—the lowest level since 1984—following the escalation of Middle East tensions, leaving very little buffer to defend against unexpected global supply chain disruptions or security crises in the future.
Q4. Do the rate hikes by the ECB and the BOJ pose a negative factor for WTI prices?
A4. Global monetary tightening shrinks liquidity in asset markets and caps marginal economic growth, which can suppress crude oil demand in the long term. Additionally, tightening in major currencies other than the dollar stimulates market interest rates, raising financing costs for purchasing commodities.
Q5. What is the outlook for oil prices starting in autumn after the peak summer season?
A5. As the July peak passes, starting in late August, refineries will lower utilization rates and enter scheduled maintenance. Consequently, as crude runs at refineries decrease, commercial inventories may build up again, potentially testing the lower bound of the price range.
