TO THE higher-ups at the US Federal Reserve, it must feel like a recurring nightmare: an overseas war driving up the prices of energy and commodities, just when the global financial system needs inflation least.

Now, some economists are even whispering that the Fed’s next action could be a rate hike, rather than a cut.
