Measures of US government policy approval are strongly related to persistent fluctuations in the dollar value. Contemporaneous correlations between approval ratings and the dollar approach 50% against advanced economy currencies. High approval ratings further forecast a decline in the dollar risk premium several years ahead and are associated with a persistent increase in economic growth and a reduction in economic volatility. We provide an illustrative model to interpret our empirical evidence. In the model, policy valuations (approvals) are forward-looking and increase at times of high expected policy-related growth and low policy-related uncertainty, which are times of a strong dollar and low dollar risk premium.
