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.

We develop a novel measure of volatility pass-through to assess international propagation of output volatility shocks to macroeconomic aggregates, equity prices, and currencies. An increase in country’s output volatility is associated with a decrease in its output, consumption, and net exports. The average consumption pass-through is 50% (a 1% increase in output volatility increases consumption volatility by 0.5%) and it increases to 70% for shocks originating in smaller countries. The equity volatility pass-through is larger and in the order of 90%. A novel channel of risk sharing of volatility risks can explain our empirical findings.
