Where do you get 2.45% from? There's nothing about that in my document. Even 1.45% is quite a markup compared to 0.72% or where I end up here. Specifically, that's about twice as much interest and that makes itself noticeable from the very beginning. And as I said, I am calculating with rising interest rates. But not to the extent that a long fixed interest period is definitely worthwhile.
And no: Italy & Co. will not go bankrupt if they now have to pay 2% instead of 1.4%. Inflation in the Eurozone offsets this. Especially since Italy and others have not been insolvent on government bonds in the past even at 3-4%
There you are comparing apples and oranges. Apart from the fact that inflation and debt ratios were lower in the past, all the countries had their own currency until just over 20 years ago. Insolvency, however, always only occurs in foreign currencies. Now the euro is (at least theoretically) a foreign currency for all member countries as they have no possibility to devalue themselves or print money. The former is still the case, the latter is attempted by all sorts of possible and impossible tricks through the back door. However, this creates a dependency of these countries on the ECB and vice versa – after all, Pandora’s box is open – a dependency of the ECB on politics within these countries. Therefore, normal monetary policy is still a long way off and accordingly, strongly rising interest rates in 10 years are quite unlikely unless inflation turns out to be significantly stronger than currently expected.
