LONDON, Aug 16 (Reuters) - Sweden's 20-year government bond yield fell below zero for the first time on Friday, taking the country's entire yield curve negative.
Sweden, where the key central bank interest rate is -0.25%, joins Denmark, Germany, Switzerland and the Netherlands with the whole bond curve yielding less than zero.
The yield on the Swedish 20-year bond, the longest dated maturity in Sweden, fell 4 basis points to -0.004% .
It is the latest example of relentless demand for government bonds amid mounting concerns about trade wars and a downturn in the global economy. (Reporting by Dhara Ranasinghe and Tommy Wilkes)
