Most people have never heard of it. That is by design. In this episode, we break down exactly how the Fed extends dollar lifelines to foreign central banks -- at what cost, under what conditions, and crucially, to whom — and explain why a tool originally built for financial emergencies has quietly become one of Washington's sharpest instruments of geopolitical leverage. From the mechanics of how a swap line suppresses interest rates globally — including how it once moved LIBOR — to the UAE's extraordinary request for access in the wake of the Strait of Hormuz crisis, this episode makes the case that swap lines are no longer just a financial backstop. They are Geopolitical leverage. All this and more on this week's episode of Milkshakes, Markets, & Madness. MMM Episode 166 (May 3, 2026)
