Fuel prices in Singapore rose on Monday (Sept 14) after over two months of unchanged prices — with posted prices for diesel crossing the $4 mark, while 98-octane petrol prices again hovered close to $4 per litre.

Shell was first to kick off changes, announcing in a price board update at 12pm on Monday that it has increased prices across its fuel offerings — 95-, 98-octane petrol, V-Power, and diesel — by 8 cents respectively.

Then, at 2.30pm, Caltex posted a 12-cent increase across its 92-, 95-, 98-octane petrol and diesel prices.

Esso was the last of the three fuel companies here to make a move, mirroring Shell to raise prices across its fuel offerings — 92-, 95-, 98-octane petrol and diesel — by 8 cents each.

Following the latest round of price adjustments, the price of the more popular 95-octane petrol now ranges from $3.36 at SPC to $3.49 at Caltex.

Meanwhile, the price of diesel now ranges from $3.89 at SPC and Sinopec to $4.07 at Caltex.

At the time of this article's publication, only SPC and Sinopec have not posted adjustments to their fuel prices.

The last round of fuel price adjustments, over July 6 and 7, was reported by AsiaOne on July 8.

At that time, prices for Brent oil futures were around US$76 (S$97) per barrel. 

As of 8.13am on Tuesday morning (Sept 15), Brent crude futures has risen to US$106.93 a barrel

This comes as Iran-backed Houthi forces in Yemen launched fresh attacks on Saudi Arabia on Monday, while Gulf Arab states postponed planned discussions with Iran, fuelling concerns that the Middle East conflict could widen and disrupt global oil supplies.

Reuters, citing three sources, reported that Washington has so far resisted Saudi requests for direct military intervention beyond intelligence support. 

Trump said over the weekend he had spoken with the crown prince and that the Houthis had also contacted Washington urging it to stay out of the conflict.

Meanwhile, Iran's Revolutionary Guards (IRGC) said in a statement: "The IRGC Navy firmly declares that the Strait of Hormuz is closed and still under our smart control."
