Monday (September 7th) was Labor Day, but risks in the Middle East and shipping continued. Saudi Aramco's Jizan refinery was attacked again, further restrictions on navigation in the Panama Canal are possible, and traffic in the Strait of Hormuz remained low. Geopolitical premiums for oil prices remained high, and concerns about refined product supply intensified. Market sentiment was tight, energy inflation expectations strengthened, gold indirectly benefited, and the US dollar may find support. Limited liquidity due to the holiday increased volatility risk at Tuesday's opening. Major US markets were closed today, but public information continued to be updated frequently. Traders were less concerned with the news itself and how the risks would be transmitted to oil prices, freight rates, inflation, and central bank policies. This article summarizes key events of the past few hours, focusing on the Saudi refinery attack, the Panama Canal navigation warning, and the situation in the Strait of Hormuz, analyzing their potential impact on US Treasury bonds, foreign exchange, gold, and crude oil. A reminder: when liquidity is thin, news is often amplified, and sentiment is more likely to dominate pricing than usual.

Saudi refineries attacked again: diesel premiums remain high.

Major overseas institutions reported that Saudi Aramco's Jizan refinery was attacked again on Monday, with the Houthis claiming to have launched dozens of ballistic missiles and drones. The refinery has a capacity of approximately 400,000 barrels per day and has been largely shut down since the end of July, with diesel shipments in August already at zero. Saudi Arabia is assessing the damage and attempting to divert crude oil exports via the Red Sea and East-West pipelines, but the loss of refining capacity is more difficult to replace. Traders should focus on refined product prices rather than crude oil: crack spreads for diesel, jet fuel, etc., are likely to continue widening. If the attacks spread to larger refineries or export terminals, a retaliatory cycle will push up risk premiums across the entire energy sector.

Panama Canal Navigation Restriction Warning: Further Pressure on Shipping Costs

The canal's new administrator warned that due to severe water shortages, daily traffic could further decrease from the already low of 32 vessels to a minimum of 27, similar to the pattern observed in the driest year of 1997. Normally, the average is around 36 vessels per day. These restrictions directly drive up freight rates for containers, dry bulk cargo, and oil, while the increased sailing days and fuel consumption due to detouring around the Cape of Good Hope indirectly raise the cost of goods arriving at the port. This creates friction in the transportation chains for crude oil, refined oil products, and precious metals. If El Niño intensifies and the dry season continues to restrict traffic, the global trade cost center may shift upwards.

Hormuz "partially open, partially closed": Structural risks remain looming.

Following the weekend's exchange of ships between the US and Iran, traffic in the Strait of Hormuz has fallen to its lowest level since May, averaging about 10 cargo ships per day. Overseas reports estimate that the Iran war has already cost US consumers approximately $100 billion in additional energy costs. This is currently the most critical structural risk. Any further restrictions—whether militarization or a sharp drop in traffic—could trigger a rapid surge in oil prices, spilling over into global inflation and shipping markets. While a geopolitical premium may persist in the short term, the signals are highly volatile, and a false breakout should be anticipated.

Transmission Logic: The Delicate Balance Between the US Dollar, Gold, and US Treasuries

High energy prices are reinforcing inflation expectations, potentially supporting the US dollar while putting pressure on the currencies of energy-importing countries. Gold indirectly benefits from risk premiums and inflation hedging demand, but if oil prices push the Federal Reserve to maintain a hawkish stance for longer, rising real interest rates could suppress gold prices. US Treasury markets are closed today, but next week's opening may reflect the impact of energy costs on inflation expectations; the risk of a steepening yield curve warrants attention. Lavrov's comments on sanctions and de-dollarization are more of a long-term narrative, with limited short-term impact, but they reinforce the backdrop of volatile risk appetite.

Sentiment and Risk: The Impact of News on Increased Holiday Liquidity

The "noise" of the Middle East conflict is causing market confusion. Any new attacks targeting key export nodes, or further militarization of the Strait of Hormuz, could cause oil prices to jump rapidly in low liquidity conditions. While the Panama climate issue is a slow-moving variable, its certainty is increasing. Traders should focus on real-time shipping flows and damage assessments, rather than chasing single headlines. Outlook: In the short term, oil prices are expected to remain bullish, with refined products outperforming crude. However, the immediate reaction to US market closures could lead to a gap at the start of next week's trading. Rising shipping costs may support commodity landed prices. Gold is supported in the short term by safe-haven demand and inflation expectations, but the direction of US Treasury yields needs to be observed. The US dollar is trending slightly stronger, putting pressure on the currencies of energy-importing countries. In the medium to long term, if the situation in the Middle East does not ease and the Panama shipping restrictions are implemented, the global energy and shipping cost center will shift upwards. Inflationary pressures may force major central banks to maintain restrictive interest rates for longer, potentially leading to high US Treasury yields and increased volatility in risk assets.

Frequently Asked Questions

Will the US market closure weaken the impact of risk events? No. The events are still unfolding, and insufficient liquidity during the holiday may actually amplify the gap volatility at the start of next week's trading, with sentiment more likely to dominate pricing than usual. How much impact will the attack on Saudi refineries have on crude oil? Jizan's capacity is approximately 400,000 barrels per day, and diesel shipments have already reached zero. In the short term, it will further push up the crack spread of refined oil products. The diversion of crude oil exports has partially mitigated the unilateral impact, but the loss of refining capacity is difficult to replace. How will the Panama Canal traffic restrictions affect the market? It will push up shipping rates, increase detour costs, and indirectly raise the landed prices of crude oil, refined oil products, and metals. If the traffic restrictions continue into the dry season, global trade costs may rise further. What is the most concerning aspect of the Hormuz situation? Traffic flow has already dropped to a low level. If it is further militarized or traffic flow drops sharply, oil prices may jump rapidly, impacting global inflation and shipping. This is currently the most critical tail risk. What will happen to gold and the US dollar? Gold indirectly benefits from risk premiums, but if oil prices reinforce expectations of a hawkish Fed, rising real interest rates may suppress gold prices. The US dollar may strengthen due to inflation concerns, putting pressure on the currencies of energy-importing countries.
