The Invesco Senior Loan ETF (BKLN) provides exposure to a diversified portfolio of senior loans, which are floating-rate debt instruments issued by corporations. This structure inherently involves interest income (riba), rendering the ETF non-compliant with core Shariah principles. Financial ratios cannot be meaningfully calculated due to the ETF's nature, but qualitative business activity screening confirms prohibition. No inclusion in major Shariah indices further validates non-compliance. Investors seeking fixed-income exposure should consider Shariah-compliant alternatives like Sukuk ETFs.
