27 March 2015 US Fixed Income Weekly dynamics, as investors and dealers reduce risk. More crucially it is likely to be related to the increased supply of duration from peripheral issuers. We had highlighted over the last few weeks that peripheral countries were likely to increase the duration of their new issuance to raise the average maturity of their outstanding debt back to pre-crisis levels. We expected the increase in duration to be a headwind to the spread tightening trend, but not to lead to a spread widening. On closer inspection, the duration supply could actually be quite meaningful. Indeed, Spain and Italy have increased the maturity of their issuance in 2015 by 2.5-3.0 years relative to 2014. If this increase in maturity is maintained for the duration of the QE programme, Spain and Italy would be issuing significant additional duration to the market relative to last year (see the table below and Euroland Strategy for more details). In fact, for Italy, the duration supply could be comparable to the duration taken out by the ECB. Of course, some maturity extension was likely to have been expected and already priced in by the market. Also, the maturity increase from Italy and Spain may be particularly high at the moment and may decelerate. Nonetheless, this simple calculation suggests that the magnitude of the duration supply could be material. Duration supply in the periphery could be material fll 12) 131= DI • l2)/ 10 Estimated Grose Mai why Incline.
