The white paper discusses participatory notes (p-notes), which are offshore derivative instruments issued by registered foreign institutional investors to overseas investors for investing in Indian markets without direct registration with SEBI. P-notes have raised regulatory concerns due to their potential use in money laundering and tax evasion, leading to stricter regulations such as KYC norms introduced by SEBI. Recent changes in tax treaties with Singapore and Mauritius may reduce p-note investments by imposing capital gains tax on transactions through these jurisdictions.
