There are growing concerns in the market that Hong Kong's MPF funds may be forced to offload large amounts of US Treasuries after Moody's downgraded the US sovereign credit rating.Currently, only Japan's R&I still gives the US the highest rating, allowing MPF funds to continue investing more than 10% of their total assets in US Treasuries. If the US loses this last top rating, MPF funds will be compelled to sell any US Treasuries holdings that exceed the cap.Related NewsContinuing Jobless Claims for May/10 in United States is 1,903K, higher than the previous value of 1,867K.
