Oil hit multi-week highs today after OPEC indicated it was likely to maintain production cuts that have helped boost prices this year, while escalating Middle East tensions provided further support. 

Brent crude was up by 34 cents to $72.55 a barrel today, having earlier touched $73.40, the highest since April 26. 

US West Texas Intermediate crude was up 24 cents at $63 a barrel, after earlier hitting a three-week high of $63.81.  

Saudi Energy Minister Khalid al-Falih said yesterday there was consensus among the Organization of the Petroleum Exporting Countries (OPEC) and allied oil producers to drive down crude inventories "gently" but he would remain responsive to the needs of a "fragile market". 

United Arab Emirates Energy Minister Suhail al-Mazrouei earlier told reporters that producers were capable of filling any market gap and that relaxing supply cuts was not the right decision. 

OPEC data indicates oil inventories in the developed world rose by 3.3 million barrels month-on-month in March, and were 22.8 million barrels above their five year average. 

A gathering of the so-called Joint Ministerial Monitoring Committee in Saudi Arabia over the weekend did not make any solid recommendations, leaving a decision on policy for a meeting of OPEC and its allies next month in Vienna. 

OPEC, Russia and other non-member producers, an alliance known as OPEC+, agreed to cut output by 1.2 million barrels per day from January 1 for six months to try to prevent inventories from increasing and weakening prices.

Adding to the bullish sentiment is rising tensions in the Middle East.

US President Donald Trump threatened Tehran over the weekennd, tweeting that a conflict would be the "official end" of Iran, while Saudi Arabia said it was ready to respond with "all strength" and it was up to Iran to avoid war. 

The rhetoric follows last week's attacks on Saudi oil assets and the firing of a rocket on Sunday into Baghdad's heavily fortified "Green Zone" that exploded near the US embassy. 

Another bullish signal for crude was a second week of declines in US drilling operations, with energy companies cutting oil rigs to the lowest since March 2018.

The rig count, an early indicator of future output, fell by 3 three to 802, General Electric's Baker Hughes energy services unit said on Friday.
