“The central planners at the G20 and OECD devised what they call a new ‘global standard’ of automatic financial information exchange between governments (i.e., GATCA) modeled on the US’s FATCA. However, GATCA would have never been possible in the first place had the US not cleared the path with FATCA. The G20 and OECD needed the US—the sole financial superpower (for now at least)—to strong-arm and cram down the throats of the rest of the world this privacy-killing measure. There’s no other entity on the planet with the capability to do so. The very big stick the US wielded was access to the US financial system and the world’s premier reserve currency.”
