The Bank of England (BoE) Chief Economist Andy Haldane said on Friday that central banks around the world might coordinate tools for dealing with specific markets.
"There may be greater scope to coordinate macroprudential tools," Haldane said. He added that macroprudential tools should "operate on an asset-class basis, rather than on a national basis".
Haldane surprised market participants last week when he said a drop in inflation meant the central bank could cut its interest rate further.
