As oil prices hit ~$107/barrel amid the Q1 2026 Middle East energy crisis, Oneok employees managing healthcare costs and HSA contributions should be aware that energy-driven inflation is rippling through the healthcare sector, affecting insurance premiums and out-of-pocket costs.

2026 Q1 Oil Market Update (March 2026): Oneok (OKE) shares are up approximately +22% over the past 90 days, with an approximate March 2026 average price of ~$112. Midstream operators are seeing elevated throughput and pipeline utilization as the U.S.-Israel joint strikes on Iran and the near-closure of the Strait of Hormuz, which carries approximately 20% of global oil and 21% of global LNG supply redirect energy flows toward North American infrastructure, boosting fee-based revenues.

The Q1 2026 oil price surge, pushing Brent to ~$107/barrel and WTI to ~$94/barrel, reflects the severity of supply disruptions stemming from U.S.-Israel military operations targeting Iran's energy infrastructure.

The natural gas complex has moved sharply alongside crude, with Henry Hub at approximately ~$2.94/MMBtu and European TTF near ~$16.90/MMBtu, reflecting Iran's successful strikes on Gulf LNG facilities that crippled nearly a fifth of global LNG supply.

The inflationary ripple effects of the 2026 oil market crisis are affecting healthcare costs, making it important for Oneok professionals to understand all available healthcare benefits and ensure their coverage aligns with their family's needs.

Medicare's Open Enrollment Period — which runs from October 15 through December 7 — is your annual opportunity to switch your current Medicare health and prescription drug plans to ones that better suit your needs. Medicare premiums, deductibles, and other costs for 2026 have been announced -- and comparing plans during Open Enrollment remains one of the most important steps a retiree can take to control healthcare costs.

What to consider
Start by reviewing any materials your plan has sent you. Look at the coverage offered, the costs, and the network of providers, which may be different than last year. Maybe your health has changed, or you anticipate needing medical care, or new or pricier prescription drugs. If your current plan doesn't meet your health-care needs or fit your budget, you can make changes. But if you're satisfied with what you currently have, you don't need to do anything. The coverage you have will continue.

During Open Enrollment, you can:

Switch from Original Medicare to a Medicare Advantage Plan
Switch from a Medicare Advantage Plan to Original Medicare
Change from one Medicare Advantage Plan to a different Medicare Advantage Plan
Change from a Medicare Advantage Plan that offers prescription drug coverage to a Medicare Advantage Plan that doesn't offer prescription drug coverage
Switch from a Medicare Advantage Plan that doesn't offer prescription drug coverage to a Medicare Advantage Plan that does offer prescription drug coverage
Join a Medicare prescription drug plan (Part D)
Switch from one Part D plan to another Part D plan
Drop your Part D coverage altogether

Any changes made during Open Enrollment are effective as of January 1, 2026.

Medicare Part B (Medical Insurance) Costs for 2026
