Oil prices edged lower on Friday and were on track for a weekly decline as interest rate hikes from major central banks fuelled worries about a sharp economic slowdown.

Brent crude was down 56 cents, or 0.5%, to $119.25 a barrel at 1204 GMT, and U.S. West Texas Intermediate (WTI) crude fell 78 cents, or 0.7%, to $116.81.

Brent was on track for its first weekly dip in five weeks, and U.S. crude for its first decline in eight weeks, in line with a fall in equity markets amid fears of a possible recession as several central banks delivered big rate hikes.

"The influence of the macro environment has started to take over from oil specific fundamentals in recent days," said Investec's head of commodities Callum Macpherson.

"Consistent with the broader market pre-occupation with rates and inflation, the oil market narrative may now turn to focus more on affordability, rather than on supply."

Both contracts had risen by more than $1 earlier in the session as U.S. sanctions on Chinese and Emirati companies and on a network of Iranian firms that help export Iran's petrochemicals lent some support to oil prices.

The U.S. government said while it is pursing diplomacy to revive a nuclear deal with Iran, it will continue to use sanctions to limit exports of oil, oil products, and petrochemicals from Iran.

Analysts estimate that a deal and the consequent lifting of sanctions on Iran's energy sector could add up to 1 million barrels of oil per day to global markets.

"The market has been watching negotiations between the West and Iran in anticipation of a revival of the nuclear deal in recent months. This brought back into focus the ongoing supply side issues in the market," ANZ Research analysts said in a note.

The global oil market continues to show signs of "turbulence", Russian Deputy Prime Minister Alexander Novak said on Friday, blaming the uncertainties over oil production recovery in Libya, Iran and Venezuela and a lack of energy infrastructure.
