Oil prices experienced a slight increase during Asian trading on Friday, as investors remained cautious in anticipation of significant U.S. employment data. This sentiment was influenced by a substantial reduction in U.S. crude inventories and a postponement of production increases by OPEC+ producers.

Brent crude futures climbed by 13 cents to $72.82 by 0507 GMT, while U.S. West Texas Intermediate crude futures rose by 12 cents, or 0.17%, to $69.27.

"Overall caution seems to dominate the market, as participants are still processing the mixed economic data from the U.S. this week, and the approach of the important jobs report may restrict some risk-taking," noted Yeap Jun Rong, a market strategist at IG.

For the week, Brent is projected to decline nearly 8%, while WTI is expected to fall by almost 6%.

This week has presented mixed signals regarding the U.S. economy, with the nonfarm payrolls data due on Friday anticipated to play a crucial role in determining the extent of a potential interest rate cut by the Federal Reserve during its meeting on September 17-18.

While U.S. services sector activity remained stable in August, the growth of private jobs has slowed, indicating a softening labor market.

"Investors may still be haunted by the early-August sell-off in global markets, which has kept sentiment on edge regarding the possibility of another unexpected downturn in U.S. labor conditions," Yeap commented.

Earlier in August, oil prices dropped by over a dollar, with Brent reaching a seven-month low due to recession fears in the U.S. that triggered a global market sell-off, although prices later rebounded amid concerns over escalating tensions in the Middle East.

On Thursday, Brent settled at a more than one-year low, as concerns about demand from the U.S. and China outweighed the support from a significant reduction in U.S. oil inventories and OPEC+'s decision to delay planned output increases.

Crude stockpiles decreased by 6.9 million barrels to 418.3 million barrels, contrasting with analysts' expectations of a 993,000-barrel draw, attributed to lower import levels.

OPEC+ has decided to postpone a scheduled increase in oil production for October and November, as announced by the producers’ group on Thursday. They indicated that further delays or reversals of production hikes may be considered if necessary.

According to analysts at ING, the market reaction to this decision has been lackluster, with ongoing concerns about demand significantly influencing negative sentiment.

On the demand side, the declining U.S. dollar provided some support, as it hovered close to a one-week low due to mixed signals from employment data.

A weaker dollar results in lower oil prices for purchasers using other currencies.
