Government Policy Approval and Exchange Rates

Measures of U.S. government policy approval, such as U.S. Presidential or Congressional ratings, are strongly related to persistent fluctuations in the dollar exchange rates. Contemporaneous correlations between approval ratings and the dollar value reach 50% against the advanced economy currencies, in real and nominal terms, in levels and multi-year changes. High approval ratings further forecast a decline in the dollar risk premium, a persistent increase in economic growth, and a reduction in future economic volatility several years in the future. We provide an illustrative economic model to interpret our empirical evidence. In the model, policy valuations are forward-looking and reflect net contributions of policy to economic growth. Policy valuations (approvals) increase at times of high policy-related growth and low policy-related uncertainty, which are the times of a strong dollar and low dollar risk premium.
