If the collapse of the system arrives then the whole kit and caboodle will likely be shut down with Bail ins arriving.
The likelihood of the metals markets being independently shut down in the western world would come from a Force Majeure event where demand overcomes the ability to supply. Considering that the LBMA has already flagged a "soft" Force Majeure situation where it was or still is taking them 8 weeks to supply what is supposed to be a T plus one day supply contract then a spike in demand for physical could easily see the metals being shut down. In regards to price they are already losing control. The important issue is the ability to supply. When that is lost then confidence in the entire daisy chain will probably break.
If you look at what the Casino owners and runners have been doing over the decades as in straitjacketing all the "coal mine canaries" along with printing and pumping massive liquidity into the Ponzi to keep it propped up along with contagion preventative downside action while lying their asses off about inflation along with anything else that suits their cause then its not difficult to see that the entire system has been stretched to its limit and all that remains is for them to pull the plug and institute their next gambit which will be the stealing of peoples assets along with their next attempt at forced total control of the population.
