US Dollar (USD)

The US Dollar (USD) is the official currency of the United States and its territories, serving as the world's foremost reserve currency and the primary medium of exchange for international trade, particularly in commodities like oil and gold, a status largely cemented by the 1944 Bretton Woods Agreement. Its value and global influence are fundamentally managed by the Federal Reserve (the Fed), which employs monetary policy tools like the federal funds rate to maintain economic stability and control inflation.
