Index-linked gilts

The Bank of England collects and publishes data relating to UK monetary financial institutions’ (MFIs’) holdings of UK government bonds (gilts) and treasury bills, split by residual maturity.
Published on 01 March 2018

These data are available in Bankstats Table B1.7.

From January 2016, this collection was extended to capture additional granularity of gilts holdings by identifying, within each maturity breakdown, the amount that relate to index-linked gilts.

Index Linked

Index-linked gilts differ from conventional gilts in that coupon and principal payments are adjusted in line with movements in inflation. Index-linked gilts are reported as a separate ‘of which’ item, for each residual maturity split. This enhanced granularity will enable users to identify, within residual maturity splits, the proportions that are impacted by changes in the Retail Price Index (RPI).

Chart A utilises the new detail and demonstrates the proportion of index-linked gilts for each residual maturity band.

Next steps

From this month, the Bank of England will publish a number of new series showing the stocks and flows of index-linked gilts. The new series will include the amount of index-linked gilts for gross long and short positions for all maturity splits. These data will be available monthly in the Database. The relevant Database codes for these series can be found in the table below.
