US refined-products futures also oscillated, Reuters reports. An increasing supply of refined products, especially diesel fuel being offered by Saudi Arabia, helped push US ultra-low diesel futures to multi-month lows intraday, adding to bearish concerns about prices in the oil futures complex.
Brent September crude fell 45 cents to settle at $56.65 a barrel, having traded between $56.33 and $57.44.
US August crude, set to expire on Tuesday, fell 74 cents to settle at $50.15, having fallen to $49.85, its first time below $50 since April, Reuters reported.
“The dollar moved up again and the market focus is back on supply and the prospect for more Iranian exports after last week’s agreement with the West over Iran’s nuclear programme,” said Gene McGillian, analyst at Tradition Energy in Stamford, Connecticut.
The seesawing dollar rose early to three-month highs on expectations of rising US interest rates, sending gold prices to their lowest in five years and helping pressure copper prices to near two-week lows.
A stronger dollar makes crude more expensive for investors using other currencies and rising US interest rates are expected to curb liquidity, possibly adding to price pressures on crude oil.
Limiting crude futures’ losses were a drop in Saudi crude exports in May and last week’s industry data showing a lower US oil rig count.
US drillers cut seven oil rigs last week following two weeks of increases, a report by oil services company Baker Hughes said on Friday.
However, as refineries around the world operate at near-maximum levels to benefit from strong profit margins, there are signs a glut in the crude oil market may be expanding to refined products.
“The big fall in US rig counts since last September has not had a negative impact on domestic production and the reduction in Saudi crude oil exports is due to domestic refinery demand as the kingdom is turning into a significant product exporter,” analysts at PVM wrote.
Refined product inventories at Europe’s Amsterdam-Rotterdam-Antwerp storage hub rose to a record last week.
Strong increases in refinery operations in recent months are set to slow in the second half of this year, reducing demand for crude oil, Vienna-based consultancy JBC Energy said.
