Foreigners have record-high exposure to long-dated US government bonds. Specifically, foreigners have increased their share of holdings of US Treasuries with a maturity greater than 10 years, see chart below.
As a result, foreign portfolios of US Treasuries are more vulnerable to the ongoing rise in long-term interest rates.
Why have foreigners over the past decade increased their exposure to US duration? Because of the prolonged period of low and negative interest rates in Europe and Japan. Global investors like high nominal yields.
