Latest figures from the US Treasury Department show that Russia and Turkey are not the only countries to dump US debt bonds. Washington’s second-biggest creditor, Japan, is doing the same.

Tokyo dumped $82.9 billion, or seven percent of its US Treasuries holdings, over the twelve months ending in June - the latest month for which data is available.

In June alone, the country sold off $18.4 billion worth of the US securities. Japan’s holding as of June totals $1.03 trillion, the lowest since October 2011, though the country still remains the second-biggest holder of US debt.
