Oil prices eased from 2019 peaks on Friday as financial development worries weighed on sentiment, pausing a three-month rally driven by OPEC-led supply cuts and U.S. sanctions versus Iran and Venezuela.

Brent crude oil futures were at $67.72 per barrel was down 14 cents or 0.2 percent from their last close. Brent hit a four-month high of $68.69 per barrel the day before.

U.S. West Texas Intermediate (WTI) futures fell 0.4 percent to $59.84 a barrel. WTI also hit a 2019 peak at $60.39 the preceding day.

"Global economic growth still remains a concern," said the director of energy consultancy Trifecta.

Financial growth has decelerated across Asia, Europe and North America, possibly denting fuel consumption.

Oil prices this year have been propped up by supply cuts by the Organization of the Petroleum Exporting Countries (OPEC) and non-allied partners such as Russia.

Canadian investment bank RBC Capital Markets said oil was still below the fiscal breakeven level in a number of OPEC nations, meaning that many manufacturers have an interest in further propping up the market.
