1964
Gold Pool
In 1964 the London Gold Pool is trying to hold the free-market price near $35. The official window is still open. The pool collapses in March 1968.
From 1961 the London Gold Pool sold gold into the market when the price rose, trying to hold the free-market price near the official $35. That attempt is underway.
The pool collapses in March 1968. Until 15 August 1971, foreign official holders can still convert dollars at the Treasury. Private Americans cannot.
