Oil prices gain on Globex after Houthi missile strike on Riyadh

The elevated start to trading reflects a market that is rebuilding risk premium on Saudi supply following a series of strikes. Smoke seen near Riyadh's airport is shifting the perceived boundaries of the conflict, even though no damage was reported. If confirmed, the Houthi claim of an attack on Yanbu would have greater implications for flows than the Riyadh incident, as it targets Saudi Arabia's Red Sea export facilities, which serve as an alternative to the Gulf route. Washington's indication that it will not participate in offensive strikes has a dual effect: it reduces the chances of a wider escalation, but in the near term leaves the Houthi assault on Saudi Arabia unchecked. Traders will be watching the Asian session to see if the bid is sustained, given that thin Sunday evening volumes can amplify moves driven by headlines.

Oil prices were bid at the open as the Houthi conflict extended to Riyadh, marked by smoke near the airport, an intercepted missile, and Washington's statement that it will not join offensive strikes.

Summary:

• In Sunday evening trade on Globex, oil prices opened higher, with the reported attack on Riyadh being one of the factors traders are assessing.
• On Saturday, Saudi civil defence issued overnight alerts cautioning about potential aerial attacks in Riyadh and Al-Kharj. At dawn, Saudi air defences intercepted a missile headed for the capital, and later, the Saudi-led coalition confirmed the Houthis had attempted to strike Riyadh with a ballistic missile.
• Residents reported at least one explosion, and video showed black smoke near King Khalid International Airport, where flight operations were heavily disrupted. The Associated Press noted no casualties or damage.
• The Iran-backed Houthis claimed responsibility for missile and drone strikes on what they termed "sensitive" locations in Riyadh, as well as an attack on an Aramco facility in the Red Sea city of Yanbu. What they targeted in the capital remains unclear.
• This marks the first time Riyadh has been targeted since the recent Saudi-Houthi escalation added another front to the broader Iran conflict. The Houthis have been striking at Saudi Arabia since July, when they announced a naval blockade against Riyadh.
• The US has indicated it has no plans to take part in offensive operations against the Houthis.

In Sunday evening trading, oil prices opened higher on Globex as traders factored in the reported attack on Riyadh after the Houthis brought their conflict with Saudi Arabia to the capital. On Saturday, Saudi civil defence sent overnight phone alerts warning of possible aerial attacks in Riyadh and Al-Kharj, east of the capital. According to Gulf News, Saudi air defences intercepted a missile at dawn, and Sky News reported that the Saudi-led coalition later confirmed the Houthis' attempt to strike Riyadh with a ballistic missile.

Residents reported hearing at least one explosion, and footage showed a column of black smoke with the main terminal of King Khalid International Airport visible in the background. The airport saw severe flight disruptions. The Associated Press stated there were no casualties or damage, though the Wall Street Journal earlier reported, citing three officials, that an air strike had struck jet fuel facilities at the airport.

The Houthis took credit for missile and drone attacks on what they described as "sensitive" sites in Riyadh, and also claimed they attacked an Aramco facility in the Red Sea city of Yanbu. It remains unclear what they aimed at in the capital, and the Yanbu claim was not corroborated in the reports seen. The Houthis, who control the most densely populated areas of Yemen and much of the north, have been striking Saudi Arabia since July, when they declared a naval blockade against Riyadh. This assault is the first on Riyadh since the latest Saudi-Houthi escalation opened another front in the broader Iran war. Washington has indicated it does not plan to join offensive operations against the rebels.

This is the context for oil's higher open, and it's investingLive's interpretation rather than a confirmed explanation. For traders, the significance lies not in any damage (none was reported) but in proximity: an attack reaching Riyadh, combined with a claim on an Aramco site, raises the possibility that Saudi energy infrastructure and export routes could be next. This follows drone attacks linked to the Iran war that halted a Saudi pipeline bypassing the Strait of Hormuz, while Iran still asserts the strait is closed. On the other hand, US Central Command said on Saturday that Hormuz shipments hit a six-month high, and Saudi forces intercepted the missile, limiting the immediate impact on supply.

Key indicators to watch include whether more attacks on Saudi targets occur, whether the Yanbu claim is confirmed, and whether Washington adjusts its position on the Houthis. A calm Monday would imply the risk premium dissipates, while another strike near Saudi energy assets would suggest it persists.
