Stock markets around the world have been gyrating in response to higher interest rates – particularly in the United States. Long-term US Government bond yields have increased significantly over the course of the past year and a half. Yields on the 10 and 30 year US Treasuries have recently reached levels that some market participants believe may become headwinds for equities. While recent advances have been steep, interest rates are still well below what would be considered “normal levels” which would imply more volatility in corporate securities markets across the globe.
