You cannot escape this reality (Ad) The last time something like this happened was 1974 - a secret deal that quietly determined the financial fate of an entire generation. According to Porter Stansberry, founder of one of the largest independent financial research firms in the world, it is happening again. Fortune calls it 'the biggest change to the world's relationship with the dollar' in a generation. Stansberry says Trump's money reset - enacted through executive orders and a treaty signed by 13 nations in December 2025 called Pax Silica - could determine whether you are enriched or quietly impoverished by the shift already underway.
