LONDON—Oil prices hit a fresh three-year high on Friday, climbing above $85 a barrel on forecasts of a supply deficit over the next few months as rocketing gas and coal prices stoke a switch to oil products.
Brent crude futures were up 80 cents, or 0.95 percent, to $84.80 a barrel at 0930 GMT. Front-month prices, which earlier touched their highest since October 2018 at $85.10, are set to climb for the sixth straight week, heading for a 3 percent hike this week.
