Central Bank Policy Rate (USD)

The primary interest rate set by the Central Bank (e.g., Fed Funds Rate, ECB Refi Rate, RBA Cash Rate, BoE Bank Rate). The policy rate is the biggest driver of currency valuations in the long term. Higher rates attract foreign investment, increasing demand for the currency and making it bullish. Forex traders constantly attempt to predict changes in this rate to position their trades.
