Nov. 20 (Bloomberg) -- Crude oil prices may fall to about $60 a barrel in this and next quarter on weak demand from developed countries and growing inventories, Macquarie’s oil economist Jan Stuart said today.

Prices will rise to an average of $80 a barrel in the latter part of next year because of the strengthening world economy, Stuart said at a conference in Hong Kong.
