May 30, 2003, the yield is 4.435%. To construct the graph, the gilt strip was repriced using increments and decrements of 10 basis points from 2.435% to 6.435%. Exhibit 4.11 shows the two price/yield relationships for the 4% coupon, 2-year Italian government and 5.75% coupon, 30-year Italian government shown in Exhibits 4.3 and 4.4, respectively. 

Gilt strips are zero-coupon bonds created from conventional coupon gilts. Only issues actually designated as strippable gilts may be stripped. They trade as conventional zero-coupon bonds and are deemed as conventional gilts in terms of their creditworthiness.

One final point regarding duration is that it is possible to calculate a tax-adjusted duration for an index-linked bond in markets where there is a different tax treatment to indexed bonds compared to conventional bonds. In the United States market, the returns on indexed and conventional bonds are taxed in essentially the same manner, so that in similar fashion to Treasury strips, the inflation adjustment to the indexed bond s principal is taxable as it occurs, and not only on the maturity date. Therefore, in the US-indexed bonds do not offer protection against any impact of after-tax effects of high inflation. That is, Tips real yields reflect a premium for only pretax inflation risk. In the United Kingdom market however, index-linked gilts receive preferential tax treatment, so their yields...

Exhibit 4.10 shows the price/yield relationship for the UK gilt principal strip that is shown in Exhibit 4.1. Recall, using a settlement date of... 

For example, consider the UK gilt principal strip discussed earlier that matures on June 7, 2021 and on a settlement date of May 30, 2003 is priced to yield 4.435%. Exhibit 4.1 presents Bloomberg s Yield Analysis screen for this security. Let s change (i.e., shock) the note s required yield up and down by 20 basis points and determine what the new prices will be in the numerator of equation (4.1). If the required yield were decreased by 20 basis points from 4.435% to 4.235%, the strip s price would increase to 46.99. Conversely, if the yield increases by 20 basis points, the strip s price would decrease to 43.99. Thus,... 

For example, consider once again the UK gilt principal strip whose duration we just computed is 17.636. The approximate percentage price change for a 10 basis point increase in the required yield (i.e.. Ay = +0.001) is... 

Assumptions The initial yields for the 2-year Italian government and UK gilt principal strip are 2.147% and 4.435% respectively. 

We demonstrated this property earlier using a UK gilt principal strip priced to yield 4.435% with a duration of 17.631. For a 10 basis point change in yield, the estimate was accurate for both an increase and decrease in yield. However, for a 200 basis point change in yield the approximate percentage price change was off considerably. 

For example, for the UK gilt principal strip, the convexity adjustment to the percentage price change based on duration if the yield increases from 4.435% to 5.435% is... 

For the UK gilt principal strip we have been using in our illustrations, the convexity measure is 3.3068.

A paper by Csiszar et al. (2013) describes manufacturing methods for metallized fibres made from the fourth century AD onwards. The metal strips were a few tenths of a millimetre in width and up to 70 mm in length. These might be wound around a textile core or used flat. Csiszar et al. (2013) also describe how silver gilt threads took over from gold around the first millennium. With reference to the literature, Csiszar et al. (2013) report that 70 types of metallized thread are known.
