Investing in Main Street Act of 2023

This bill amends the Small Business Investment Act of 1958 to require Small Business Investment Companies (SBICs) licensed by the Small Business Administration to invest at least 15% of their capital in small businesses, up from the previous 5% requirement. The change directly affects SBICs, which are private investment firms that channel capital into small businesses. By raising this minimum investment threshold, the bill aims to increase funding flow to small businesses through these licensed investment vehicles. The provision applies to all new SBIC investments under the amended law.
