Is DUK (Duke Energy Corporation) Halal or Haram?

Based on our AAOIFI-standard shariah screening, DUK is classified as Doubtful. It passed 3 of 4 compliance screens. Some scholars may permit investing with income purification, while others advise avoiding it. We recommend consulting a qualified Islamic scholar before investing in DUK.

Duke Energy Corporation is one of the largest energy holding companies in the United States, providing electricity and natural gas to millions of customers. The company operates through segments including Electric Utilities and Infrastructure, Gas Utilities, and Commercial Renewables, utilizing a mix of coal, nuclear, natural gas, and renewable sources. For Muslim investors utilizing HalalStocks.co.uk, Duke Energy currently holds a Doubtful shariah compliance status. While the underlying utility business is universally considered halal, the stock fails critical AAOIFI financial screens, meaning it cannot be confidently added to a strictly compliant portfolio. The primary concern from an Islamic finance perspective is the company's heavy reliance on interest-bearing debt. Duke Energy's Debt to Market Cap ratio stands at an excessive 92.2%, well above the 33% maximum limit, even though its cash reserves and interest income are well within permissible bounds. Investors focused on shariah compliance should monitor the company's capital structure and debt management. Until Duke Energy significantly reduces its leverage to meet the 33% threshold, Islamic investors may need to look for alternative utility stocks with healthier balance sheets. Duke Energy Corporation operates in the Utilities sector under the Regulated Electric industry and is headquartered in Charlotte, NC, US. The company is led by CEO Harry K. Sideris and employs approximately 26,413 people.

DUK was screened using AAOIFI-based shariah compliance criteria. Four tests are applied: (1) Business Activity — the company's core business must not derive primary income from haram (prohibited) activities such as alcohol, gambling, tobacco, or interest-based finance. (2) Debt-to-Market-Cap — total debt must not exceed 33% of market capitalization. (3) Interest Income — interest income must not exceed 5% of total revenue. (4) Cash & Securities — cash and interest-bearing securities must not exceed 33% of market cap. DUK passed 3 of these 4 screens.

DUK was last screened on 2026-04-29. Shariah compliance status can change as companies report new financial data, acquire new businesses, or shift revenue streams. We recommend checking back periodically for the most up-to-date screening results.
