The dollar reset no one told you about (Ad)

Porter Stansberry says a dollar reset is underway - one that has happened only once before in America's 250-year history, back in 1974 with a secret Saudi deal that reshaped an entire generation's wealth. Today, a landmark treaty called Pax Silica - signed by 13 nations in December 2025 and barely covered in the press - is at the center of what Fortune calls 'the biggest change to the world's relationship with the dollar' in a generation. The stocks to buy, the assets to avoid, and the moves to consider are outlined in Stansberry's new briefing.tc pixel

It’s not about Greenland (Ad)

The petrodollar arrangement that anchored the US dollar for 50 years quietly expired in June 2024. Since then, China has cut its Treasury holdings by 45% from their peak, and BRICS nations offloaded $47 billion of American debt in a single month. The Trump administration has responded with a $12 billion critical minerals stockpile called Project Vault, equity stakes in miners like MP Materials and Lithium Americas, and a push to secure resources from Greenland to Ukraine. Porter Stansberry lays out the full story in a new documentary, including five companies positioned at the chokepoints of what he calls Trump's New Dollar.tc pixel
