As the light dimmed in one of the few bright spots in the world economy, the United States, demand for bonds firmed - a factor highlighted by the Bank of England's failure on Tuesday to prise enough debt from investors to meet its bond-buying target under plans to stimulate Britain's economy. sub-par global growth and inflation keeping the onus on looser central bank policy, New Zealand, one of the 55 monetary authorities to ease policy since the start of 2015, was broadly expected to cut rates further on Thursday.
"Central banks look increasingly accommodative and no one seems to be going against that trend ... which supports all asset prices," said Anton Heese, head of European rates strategy at Morgan Stanley (NYSE:MS) in London.
