Not all energy shocks are alike. This column uses a multi-country, multi-sector DSGE model with production networks and trade linkages to compare a Europe-centric regional energy shock — akin to the 2022 Russian gas crisis — with a broader global energy shock like the current Strait of Hormuz disruption. The global shock worsens the EU's terms of trade more severely and triggers exchange rate depreciation rather than the appreciation seen under a regional shock. Crucially, while the regional shock still allows firms and consumers to substitute towards cheaper foreign goods and inputs, the global shock closes off this escape route — amplifying both the GDP contraction and the indirect inflationary effects through global supply chains.

Financial markets pay close attention to monetary policy, and surprise policy decisions can strongly affect asset prices and the real economy. This column shows that financial markets care not only about the size of monetary policy surprises, but also whether the central bank over-delivers or under-delivers on market expectations. Short-term interest rates react up to ten times more strongly when central banks over-deliver. Moreover, it finds that information effects emerge primarily in over-delivery episodes. In an era in which central banks increasingly rely on communication and expectation management, decisions that exceed expectations may communicate more than the policy move itself.
