We estimate international spillovers from both conventional and unconventional US monetary policy. We use novel measures of exogenous variation in conventional policy, forward guidance and large-scale asset purchases (LSAPs), based on high-frequency asset price surprises around a broad set of Federal Reserve communications. The identification relies on relatively weak assumptions and accounts for potential endogenous policy components – including central bank information effects – in these asset price surprises. We find that: (i) conventional policy, forward guidance and LSAPs all generate large and comparable spillovers; (ii) these spillovers transmit through trade and financial channels to a similar extent; (iii) LSAPs trigger immediate international portfolio rebalancing between US and foreign bonds that are relatively close substitutes, but they produce only limited spillovers in term premia; (iv) all Fed policy measures create trade-offs for emerging market monetary policy between stabilizing output and prices vs. ensuring financial stability, particularly with regard to capital inflows.
