Motivated by the dominant role of the US dollar, we explore how monetary policy (MP) shocks in the US can affect a small open economy through the expectation channel. We combine data from a panel survey of firms' expectations in Uruguay with granular information about firms' debt position and total imports on a monthly basis. We show that a contractionary MP shock in the US reduces firms' inflation and cost expectations in Uruguay. This result contrasts with the inflationary effect of this shock on the Uruguayan economy, suggesting uncertainty about the policy regime. We discuss the issues and challenges of this expectation channel.
