Since the Federal Government’s entry into this market segment in 2006, the investor base, financing flexibility and spectrum of securities offered has been continually expanded. Based on the previous success achieved in the form of significant interest cost savings, one of the Federal Government's strategic goals is to build up the entire German Government security yield curve. Unlike the somewhat short and volume-heavy issuance tendencies for nominal bonds, inflation-linked bonds are initially placed in smaller volumes across a number of months, followed by smaller increases until each security reaches the benchmark figure of 15 bn.

Inflation-linked German Government securities are now an established part of the Federal Government's financing strategy. Their share of total annual issuance volumes amounts to almost 4 % an average since 2006.

There are currently six inflation-linked German Government securities in circulation: one five-year note, four 10-year bonds and one 30-year bond.
After the original first inflation-linked 10-year Bund matured in April 2016 the inflation-linked 5-year Bobl issued in 2011 is the first point on the German Government real yield curve. The maturity of this last inflation-linked Bobl on 15 April 2018 will reduce the total outstanding volume of inflation-linked securities by € 15 bn. The last point of the real yield curve is represented by the recently issued inflation-linked Bund maturing in 2046.

Currently the six current tradable securities have a total volume of € 75 bn. This accounts for around 7 % of all German Government securities in circulation at year-end 2017, up from 6 % at year-end 2016.

Primary market

The liquidity of index-linked securities is also increasing in parallel to the volume in circulation. The auctions generally take place on a monthly basis, with the exception of August and December.

The ten auctions of inflation-linked securities in 2017 summed up to € 6.5 bn - the same auction pattern and issuance volume as in 2016. A bidding volume of around € 9.9 bn and an allotted volume of around € 5.2 bn result in an average bid-to-cover ratio of 1.9.

The issues in the inflation-linked securities segment are an integral part of the Federal Government's strategic issuance planning. They should continue to take place on a monthly basis, with the exception of August and December. As a rule, they take place on the first or second Tuesday of each month. The announcement of the exact security and issuance volume will be published few days before the issuance date.

In contrast to the issuance volumes of nominal bonds which already had been fixed within the issuance calendar for the whole year, the issuance amount of the inflation-linked bonds is specified on a daily basis. Their share increases during the year with each new issuance of an inflation-linked bond (whereby the shares of the nominal bonds decrease slightly).

Secondary market

The outstanding volume and liquidity of inflation-linked securities have increased continually since they were first issued. The trading volume of indexed securities in 2016 totalled around € 175 bn (based on secondary market statistics from the Bund Issues Auction Group).
Thanks to the total volume of inflation-linked securities currently outstanding, the issuer can draw on a comfortably deep market, providing it with sufficient flexibility to support secondary market activities.
