Finanzen: Rendite von US-Staatsanleihen erreicht Hoch seit Finanzkrise

The sale of US Treasury bonds continues on global markets, with the decline in prices continuing in the United States. As a result, the yield on ten-year bonds rose to 5.025 percent on Tuesday morning, marking the highest level since the 2007 financial crisis. The yield of ten-year US Treasury bonds has already increased by over one percentage point since the beginning of the Iran war at the end of February.

High interest rates pose a significant problem for governments, as they greatly increase the cost of borrowing. The reason for the heavy sales of bonds is inflation concerns stemming from the Iran war. As rising oil prices drive up consumer prices, economists anticipate higher and more prolonged inflation, along with increased central bank interest rates.

While the European Central Bank recently raised interest rates, a rate hike by the US Federal Reserve is expected this coming Wednesday. Concerns also surround the growing debt in several industrial nations, notably the United States, where the debt mountain recently surpassed 40 trillion US dollars. Treasury bond yields are rising - consequences for builders.

Even the Eurozone and Germany are affected by the crisis in the bond market: the yield for benchmark ten-year government bonds rose to 3.57 percent on Tuesday, reaching a multi-year high. At the end of February, it was still around 2.6 percent. This increase has implications for homebuyers and builders in Germany, as mortgage rates are based on ten-year government bonds.

As of late June, mortgage rates for ten-year fixed-term loans had risen to around 4.25 percent annually, according to the analysis firm Barkow Consulting. This is 0.60 percentage points higher than in June and the highest level since May 2011. Builders and homebuyers typically finance large sums through loans, so even small increments can become costly and render plans obsolete.

Experts believe further interest rate hikes are possible. "We are approaching potential 4.5 percent for mortgage rates," warns Max Herbst, founder of the Frankfurt-based financial consultancy FMH-Finanzberatung.
