The iShares 20+ Year Treasury Bond ETF (TLT) is a fixed-income ETF that invests in long-term US Treasury bonds, generating returns primarily through interest payments. This core activity involves riba (interest), rendering it non-compliant with Shariah principles across all major screening methodologies. Financial ratios are inapplicable due to the ETF structure, but business activity screening fails decisively. No inclusion in Shariah indices confirms its non-compliant status. Investors seeking Shariah-compliant fixed-income exposure should consider sukuk-based alternatives.
