Telegraph Money Market report: Soaring bond yields signal trouble ahead: "Bond yields worldwide reached 12-month highs last week with the yield on the benchmark 10-year US Treasury bonds rising above 5 per cent for the first time in almost four years on Thursday. The latest selloff was prompted by fears that interest rates in the world's largest economy might rise further than expected.

Government bond prices around the globe have fallen markedly in the first quarter of this year, and the corresponding yields have surged higher. This follows signs of economic strength and concerns about inflation in the US, Japan and Europe, leading to worries that central banks will continue to increase interest rates in the coming months."
