A key dispute in the U.S. Clarity Act is whether stablecoin intermediaries can offer yield. Allowing this, even partially, would expand stablecoins' use from payments to digital savings. This could attract rate-sensitive global holders, significantly increasing long-term demand for the U.S. dollar and strengthening its monetary policy transmission abroad.

To extend the solvency of U.S. debt, create a one-to-one stablecoin backed by treasuries. This would grant global citizens, particularly in countries with unstable currencies, a direct way to save in a dollar-denominated asset. This new demand could lengthen the runway for U.S. fiscal policy.

Stablecoin adoption by U.S. entities merely shifts existing dollar assets from bank deposits or money market funds. True new demand for the U.S. dollar only materializes when foreign households or corporates convert their local currencies into dollar-backed stablecoins for the first time, creating a net FX conversion.

By making T-bill-backed assets easily accessible to retail investors worldwide via smartphones, stablecoins could unlock a massive new pool of capital. This would create trillions in indirect demand for US Treasury paper, helping to finance US debt at lower rates while simultaneously advancing US geopolitical goals.

The primary, world-changing use case for stablecoins isn't cheaper domestic payments. It's providing global, frictionless access to the U.S. dollar. This allows citizens in countries with unstable currencies or untrustworthy central banks to opt-in to the U.S. financial system, effectively exporting America's most powerful product.

When individuals in a foreign country adopt USD stablecoins, their central bank must exchange local currency for US dollars, depleting its foreign exchange reserves. This creates a feedback loop, weakening the local currency and pushing up dollar borrowing costs, making the stablecoin even more attractive and accelerating dollarization.

The US is embracing stablecoins to maintain the dollar's global dominance. By enabling easy access to digital dollars worldwide, it creates new, decentralized demand for US treasuries to back these stablecoins, offsetting reduced purchasing from foreign central banks.

Beyond a fintech innovation, USD stablecoins can be used by the US government as a tool of economic statecraft. They can direct foreign investment into strategic US sectors, create new demand for Treasury debt, and provide a mechanism to enforce sanctions by electronically controlling capital flows globally.

Stablecoins are being framed as a geopolitical tool for US monetary influence. By providing global citizens with easy access to a digital dollar, they effectively 'vampire attack' and extract capital from other nations' monetary systems, reinforcing US dollar hegemony and prompting capital controls from countries like the UK.
