U.K. investors are looking east to work out what more the Bank of England may do to help support the country’s coronavirus-addled economy.

While the central bank is widely anticipated to focus on expanding its quantitative-easing program on Thursday, speculation is building that it will impose yield-curve control — a policy pioneered by the Bank of Japan — in the coming months.

The aim would be to target specific levels in its buying of government bonds, stifling increases in borrowing costs. That would help the government finance its massive support package to revive economic growth at a low cost for a long time.
