Global spillovers from multi-dimensional US monetary policy

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.
