Lewis Ranieri

Lewis Ranieri is a prominent American businessman and banker, widely regarded as a pioneer in the mortgage-backed securities market. In the 1980s, he played a key role at Salomon Brothers, where he developed innovative financial products that pooled home mortgages into securities sold to investors. This practice helped increase liquidity in the housing market and made borrowing more accessible for homeowners. Ranieri’s work significantly transformed the financial landscape, contributing to the growth of modern finance, but also later raised concerns about risk and regulatory issues in the banking industry. He remains influential in finance and philanthropy today.
