Bref, il ne faut pas s’attendre à voir remonter les rendements des fonds € avant un (très) long moment, à mon avis.
there are no signs that the effects of our asset purchases started to evaporate the moment we stopped expanding our balance sheet. Indeed, I would argue that the effects of asset purchases are highly persistent, and that they have affected recent pricing dynamics in two important ways: through a yield level channel and through a yield sensitivity channel.
The first channel relates to the growing evidence that central banks, through their stocks of acquired assets and by reinvesting maturing principals, can persistently lower the yield level around which investors evaluate changes to the economic outlook.
I have laid out the mechanics behind the persistent impact of asset purchases in previous speeches. In short, as the central bank reduces the bond free float – the share of outstanding government bonds held by private price-sensitive investors – it also reduces the compensation, or term premia, that investors, as a whole, demand for holding long-term bonds. (...)
The implication of this is that the stock effect of our purchases will continue to be significant, as you can see on my next slide. Two years from now, the stock of acquired assets is still estimated to compress the ten-year term premium in the four largest euro area government bond markets by some 70 basis points. The main reason why the effect gradually becomes smaller in the coming years is due to the mechanical ageing of the portfolio. (...)
All this suggests that, by reducing the bond free float, stock effects may have helped temper the impact of demand shocks and foreign spillovers on yields. This is not to say that markets have lost their price discovery function. Just consider the large swings in yields we have seen over the past two years, and the changing constellation of intra euro area spreads. The APP has not suppressed market discipline.
