Although the creation and redemption of ETF shares takes place largely behind the scenes for most investors, the process is a defining feature of the ETF structure.

Setting the Stage

As a starting point, let’s discuss the differences between the secondary and primary markets for ETF shares.

The secondary market, which includes the widely recognised securities exchanges, is where investors buy and sell existing shares of ETFs. For example, if you wish to buy 2,000 shares of an ETF, you typically place an order through your brokerage account and purchase those shares at market price from other sellers in the secondary market.

The primary market refers to where ETF share creations and redemptions take place in large specified units. It provides an additional “layer”, or source, of liquidity that can be accessed for large orders or when demand exceeds supply, or vice versa, on the secondary market. Typically, large financial institutions, authorised participants, and market makerstransact in the primary market. Market makers buy and sell ETF shares in the secondary market to provide liquidity and may also serve as authorised participants.

Authorised Participants

Authorised participants (APs) are an important part of the creation and redemption process. To create new passively managed ETF shares, the AP generally acquires shares in all of the underlying securities that compose the ETF, in the same proportions as the fund’s index. To create new ETF shares the AP will deliver all of the underlying securities that compose the ETF or the equivalent cash amount and in exchange, receives shares of the ETF in blocks known as creation units. The AP then sells these ETF shares in the secondary market. The additional supply of shares tends to bring the ETF’s price back in line with its NAV2.

Carefully Crafted Creations

When there are not enough ETF shares available on the secondary market to satisfy demand, an ETF may begin trading at a premium (its current market price is higher than its NAV). When this happens, an AP may step in and create new shares.

To create new passively managed ETF shares, the AP generally acquires shares in all of the underlying securities that compose the ETF, in the same proportions as the fund’s index. On the primary market, the AP then delivers this basket of securities to the ETF issuer, and in exchange, receives shares of the ETF in blocks known as creation units3. The AP then sells these ETF shares in the secondary market. The additional supply of shares tends to bring the ETF’s price back in line with its NAV.

Road to Redemptions

The process described above also works in reverse when demand is low. For example, let us imagine that an ETF begins trading at a discount (its current market price is lower than its NAV). The AP leaps into action, buying shares of the discounted ETF on the secondary market and tendering these shares to the issuer for shares of the ETF’s underlying securities.

Redemptions reduce the number of ETF shares available on the secondary market. As a result, the discount shrinks or disappears as the ETF share price moves closer in line with its NAV.

ETF 102 Creation Redemption

Sources of Liquidity

So, there are actually two primary sources of ETF liquidity: the secondary or open market, consisting of shares bought and sold throughout the day, and the primary market managed by APs. Most ETF investors rely on secondary market liquidity.

Primary market liquidity draws on the liquidity of the underlying securities comprising the ETF. Very large trades can tap into the deeper liquidity source of the primary market, where large blocks of ETF shares can be either created or redeemed.

In Summary

Creations and redemptions are critical to the structure and liquidity of ETFs. Through this mechanism the supply of ETF shares in the open market can be brought in line with demand, thus fairly pricing ETFs.
