The Indian capital markets are relatively undeveloped. The capital market includes primary markets where new stock and bond issues are sold, and secondary markets where existing securities are traded. Historically, trading in India was unorganized under informal associations and lacked regulation. Over time, stock exchanges were established in major cities and regulations were developed, though the markets remained relatively small under British rule and in the early post-independence period. Market development accelerated in the late 20th century with economic reforms, establishment of regulatory authorities, and new technologies and participants.
