What role do Authorized Participants play in the context of ETFs?

Authorized Participants (APs) are crucial to the functionality of Exchange-Traded Funds (ETFs). They have a unique role that involves the ability to buy and redeem ETF shares directly with the fund. This process is essential for maintaining the liquidity and market efficiency of ETFs. When APs create new shares of an ETF, they deliver a basket of the underlying securities to the ETF provider, which in turn issues new ETF shares. Conversely, when APs want to redeem shares, they return ETF shares to the provider and receive the underlying securities.

This mechanism allows for the smooth operation of the ETF market, ensuring that the market price of the ETF shares stays close to the net asset value (NAV) of the underlying assets. Without Authorized Participants, the capacity for an ETF to track its index accurately and maintain an efficient market would be severely hindered.
