Oil hits 7-year peak

Oil prices rose to a more than seven-year peak on Friday and recorded their sixth straight weekly gain as geopolitical turmoil exacerbated concerns over tight energy supply.

On a weekly basis, the benchmark contracts notched their longest run of gains since October.

Brent futures rose 69 cents to settle at $90.03 a barrel, after hitting $91.70, the highest level since October 2014.
