A buyback is the repurchase of outstanding debt securities by an issuer. It is the opposite of a tap, where issuers are selling additional debt securities that become fungible, after lockup, with the first issued securities.
Issuers will buy back debt instruments either to reduce outstanding debt levels, or to provide liquidity to the market for their own instruments. Issuers can also increase liquidity by increasing the number of available debt instruments through taps. This increases liquidity as the number of available bonds increases. It is necessary because bond holders tend to be buy and hold. This means that over time the available stock of secondary bonds, becomes less and less, which can affect pricing. To promote a liquid curve, bond issuers tap specific benchmark maturities.
Governments and other larger issuers tap and buy back very frequently. The total Issued Amount (including taps) therefore does not always reflect the total amount of outstanding bonds. The oustanding amount increases with a tap and decreases with a Buybacks.
In the Collaborative Bond and Money Market Data Model the Tap classification appears within the field Amount which is part of the universe of Bond and Money Market Instruments.
Based on available data, on the 1st of February, 2016 the size of Taps in the International Bond Market was USD1.3 trillion equivalent, in 21 different currencies.
