The dollar is the world's reserve currency — yet it swings daily. Understanding the drivers explains why 'today strong, tomorrow weak' is normal. Here is what moves it.

Principal Drivers
- Interest rates: higher US yields attract capital, strengthening the dollar.
- Economic data: strong jobs/inflation prints lift it.
- Risk sentiment: fear pushes money into dollars; optimism sends it elsewhere.
- Fed policy: rate expectations swing the currency.
Why It Flips Daily
Markets price news constantly — data surprises, policy hints and geopolitical events shift sentiment hour to hour. One day's strength reflects that day's news.
What It Means for You
Dollar strength changes the price of imports and the naira/dollar rate. Track the drivers rather than daily noise.
