LONDON, July 3 (Reuters) - Meghan Greene, who is due to join the Bank of England's Monetary Policy Committee this week, said central banks should not assume that interest rates will settle back down at their pre-coronavirus levels along with lower inflation.

In a column published by the Financial Times on Monday, Greene said it was unclear if a long-term downward trend in the underlying rate of interest in the world economy would resume, or if other factors would push it up.

"But it would be a mistake for central bankers to take comfort in the notion that inflation and rates will automatically go back to the low levels we saw before the pandemic. This is their challenge for the future," she said. (Writing by William Schomberg; editing by David Milliken)
