Thank you for your reply, 99921.
I agree with the definition of "Force Majeure" but Macleod's words destabilising not only for the price and demand for silver but also disruptive for gold seem to imply a negative force on the gold and silver market and that would negatively impact the price.
If the defaulting party cannot deliver the gold, this would HAVE to have an upward effect on price, not downward.
Is Macleod an individual with an anti-PM bias like Christian, Nadler and van Eeden, by chance?
