As oil prices hit ~$107/barrel amid the Q1 2026 Middle East energy crisis, EOG Resources 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.

Oil prices have climbed sharply in March 2026, with Brent reaching ~$107/barrel and WTI near ~$94/barrel, as geopolitical escalation in the Middle East has dramatically curtailed tanker traffic through the Strait of Hormuz.

Beyond crude oil, natural gas markets face significant pressure — Henry Hub near ~$2.94/MMBtu and European TTF near ~$16.90/MMBtu — as the Middle East conflict has disrupted global LNG trade flows and redirected supply toward higher-premium markets.

The inflationary ripple effects of the 2026 oil market crisis are affecting healthcare costs, making it important for EOG Resources 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:

1. Switch from Original Medicare to a Medicare Advantage Plan

2. Switch from a Medicare Advantage Plan to Original Medicare

3. Change from one Medicare Advantage Plan to a different Medicare Advantage Plan

4. Change from a Medicare Advantage Plan that offers prescription drug coverage to a Medicare Advantage Plan that doesn't offer prescription drug coverage

5. Switch from a Medicare Advantage Plan that doesn't offer prescription drug coverage to a Medicare Advantage Plan that does offer prescription drug coverage

6. Join a Medicare prescription drug plan (Part D)

7. Switch from one Part D plan to another Part D plan

8. 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

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

Most people with Medicare who receive Social Security benefits will pay the standard monthly Part B premium of $202.90. This premium adjusts annually based on healthcare costs and adjustments in Part B items and services ( Grant Thornton ) ( Kiplinger.com ).

People with higher incomes may pay more than the standard premium. If your modified adjusted gross income (MAGI) as reported on your federal income tax return from two years ago (2024) is above a certain amount, you'll pay the standard premium amount and an Income-Related Monthly Adjustment Amount (IRMAA), which is an extra charge added to your premium, as shown in the following table ( Grant Thornton ) ( Kiplinger.com ).
