I'm not an expert and this is really complicated but "let me skip to the end..." Shadow Banking System becomes riskier and more unstable by the day... which leads to a host of unintended consequences.

According to this video: 90% of debt nominal in US currency As markets & industry become unstable countries and central banks need dollars The fed loans foreign central banks dollars (which they don't repaid) to repaid US loans (lol) Use dollars to prop up their industries which compete against US companies Central banks around the world beg for US loans Some are hostile to US If they fail to get loans... Political option... nationalize US companies in those countries... especially gold mining companies
