Do the benefits of central bank transparency depend on the structure of financial markets? We address this question in a two-country model with dispersed information among price-setting firms. The volatility of the real exchange rate is non-monotonic in the precision of public communications. Despite this non-monotonicity, under complete markets, greater provision of public information always improves welfare and full transparency is optimal. By contrast, under incomplete markets, more accurate public signals can decrease welfare by exacerbating the cost of cross-country demand imbalances. If the trade elasticity is low, optimal public announcements are intentionally imprecise.
