West Texas Intermediate (WTI) crude oil prices settled around $91.50 a barrel in early Asian trading on Tuesday, posting a slight increase amid escalating geopolitical tensions and growing market skepticism about energy diplomacy agreements. This rise was primarily driven by market doubts about the possibility of an energy "ceasefire" between Russia and Ukraine. This followed Ukrainian President Zelensky's confirmation that Russia had bombed six key energy infrastructure sites in Ukraine, suggesting Russia's unwillingness to adhere to the bilateral ceasefire agreement previously proposed by US President Trump. Despite Washington's announcement of a temporary agreement allowing Russian diesel exports to global markets—aimed at encouraging Moscow to return to the negotiating table after previous diplomatic efforts faltered—traders remained focused on the issue of imminent supply disruptions. Adding to regional supply concerns was a new round of Houthi drone and missile attacks on Saudi Arabia, launched by the Saudi-led coalition in Yemen, following the devastating attack on Riyadh's King Khalid International Airport over the weekend, which killed 16 people and injured nearly 300 others. In response, the Yemeni armed forces warned international airlines against using Saudi airspace, exacerbating concerns about supply chain bottlenecks. This prompted Scott Sheldon, a market strategist at TB ICAP, to note that a flurry of news reports had plunged the energy market into a volatile and complex environment. Market participants are also gearing up for upcoming weekly inventory reports, starting with the American Petroleum Institute’s (API) crude oil stock data later on Tuesday. A larger-than-expected decline in inventories would indicate strong underlying demand and bolster the short-term bullish outlook for West Texas Intermediate (WTI); while an unexpected increase in inventories would suggest a supply surplus and could cap price movements. Meanwhile, institutional analysis from HSBC asserts that a severe energy shock in 2026—primarily stemming from conflicts in the Middle East—has directly impacted the sovereign bond market. HSBC strategists note that while the implied volatility indicators for crude oil (the Oil Volatility Index) and the bond market (the Moving Average Convergence Divergence) typically move in tandem in the early stages of a crisis, they have recently diverged. Although spot crude oil prices have stabilized after peaking, sovereign bond yields continue to rise. HSBC cautions that lower oil prices alone are insufficient to fully resolve the overall turmoil in the bond market, given the systemic financial pressures stemming from the initial surge in yields and the continued high volume of corporate bond issuance. From a technical analysis perspective on the daily chart, the short-term outlook for WTI crude remains bullish, with spot prices holding above the middle Bollinger Band. The 14-day Relative Strength Index (RSI) is hovering around 54, in neutral territory, reflecting a healthy consolidation phase after being in overbought territory in late September. The overall uptrend remains strongly supported by the 100-day moving average, and the technical structure remains robust. Dynamic support lies around the middle Bollinger Band at $91.60, with secondary support around the lower Bollinger Band at $86.50, where traders may defend their positions during any further market pullbacks. Should spot prices hold above the primary middle band at $91.60 and break above the upper Bollinger Band around $96.70, a technical path toward recent highs could be reopened.
