“Without the reference to a June review  Russia would have been tied to the end of 2018; it wanted instead to have an escape clause ”  Petromatrix strategist Olivier Jakob  said.
“It leaves a question mark about the second half [of 2018] and about the commitment of Russian oil companies  which will be price dependent ”  he  said.
The CEO of Russia’s top private producer Lukoil told Reuters  he  would like to see the price of oil stable at current levels  trading in the $60-65 per barrel range.
The oil market is unlikely to overheat   he  added  thanks to cooperation between OPEC and its allies which would allow them to release new output into the market to rebalance it.

WASHINGTON (Reuters)  - U.S. Senator Bob Corker   the influential Republican chairman of the Senate Foreign Relations Committee  said on Tuesday he will not run for re-election  a blow to a party already struggling to balance divisions between mainstream and more populist wings.
An establishment Republican   Corker  has been criticized from the right  and a conservative activist had already announced a primary challenge. But he was expected to keep the seat  and had amassed a $7.5 million campaign war chest.
 Corker  has ruled out running for governor of Tennessee.
âI have no idea what Iâm going to do. No idea whatsoever â  Corker  said in an interview. But he said he was not leaving out of frustration over deep party divides that have often paralyzed Congress.
 Corker  announced  his  retirement on the day of the failure of the latest Republican effort to repeal former Democratic President Barack Obamaâs healthcare law.
âI am not going to be one of the people who leaves here badmouthing what is one of the greatest privileges of oneâs life â  Corker  said.
He said he realized he was ready to retire on Aug. 24 during a factory groundbreaking in Clarksville  Tennessee  and almost announced his decision at least twice before Tuesday.  Corker  said that he made his announcement now to allow a strong candidate time to enter the Senate race.
 Corker  is the first senator to announce  his  retirement ahead of the 2018 mid-term elections  when one-third of the 100-seat chamber will be up for grabs. Tennessee is a solidly Republican state and the party  which currently holds a 52-seat majority in the Senate  is favored to keep his seat.
In his official announcement   Corker  said that âafter much thought  consideration and family discussionâ over the past year  he and his wife Elizabeth âhave decided that I will leave the United States Senate when my term expires at the end of 2018.â

CLASHES WITH  TRUMP
In August  after Trumpâs much-criticized reaction to violence at a white supremacist rally in Virginia   Corker  told reporters in  his  home state Tennessee that Trump had not been able to demonstrate the âstabilityâ or competence that  he  needed to be successful as president.
After the exchange  the two men had an hour-long meeting at the White House this month that  Corker  has described as a wide-ranging and friendly discussion.
 Corker  will remain chairman of the Foreign Relations Committee until he leaves in January 2019. He said he wanted the panel to address issues including Secretary of State Rex Tillersonâs State Department reorganization  food aid reform  and the fight against human trafficking and modern slavery.
 Corker  said the committee would address the international nuclear agreement with Iran  as Trump faces a mid-October deadline for deciding whether to certify that Tehran is complying with that pact. That decision could force Congress to decide whether to reimpose sanctions.  Corker  would not say whether Trump had decided to certify or not.

Norway ’ s $ 1 trillion sovereign wealth fund will this year step up its assessment of the risks posed by climate change to its investments in power producers   oil firms and basic materials companies   its CEO told Reuters on Tuesday . Separately   the board of the central bank will soon decide whether to blacklist from the fund one or more companies -- either in the oil   steel or concrete sectors -- for producing too much greenhouse gases   the central bank chief told Reuters . The fund   which invests the proceeds from Norway ’ s oil and gas production for future pensions in stocks   bonds and real estate abroad   is one of the world ’ s biggest shareholders   with stakes totaling 1 . 4 percent of all listed companies . In recent years the world ’ s biggest sovereign wealth fund has become a more active shareholder   trying to influence companies ’ attitudes . Among them are the way companies report on climate change   such as their carbon dioxide emissions   or whether companies have scenario analyses of how more heatwaves   droughts or floods might affect their earnings .  Chief Executive Yngve Slyngstad  said the fund would first focus  its  efforts on electricity producers . “ That is ... the sector that we will first go through and think about in this scenario . The two next ones will be ( basic ) materials and oil .” “ By far the largest ... is electricity producers   which of course has been a specific focus for us because of the so - called coal criteria  ” he said referring to the fund not being allowed by parliament to invest in firms that derive more than 30 percent of their revenue from coal . The proposal to potentially exclude one or more companies in the oil   steel or cement sectors over excessive greenhouse gas emissions is under review by the board of the central bank . “ We have received some recommendations on potential exclusions based on that new criteria . The board is working on the issues ... It ’ s not going to be long  ” central bank governor Oeystein Olsen said   declining to give a more precise timeframe . Slideshow ( 2 Images ) The moves come as the fund is proposing to drop oil and gas stocks from its benchmark index   which would reduce over time its stakes in oil and gas companies . That proposal is under consideration at the finance ministry and will be voted by parliament at a later stage . DOUBLED ITS RETURN IN 2017 Also on Tuesday   the fund said it doubled its return on investment in 2017   beating its benchmark   as strong global stock markets boosted the value of the portfolio . It earned a return of 13 . 7 percent in 2017   up from 6 . 9 percent in 2016 . “ The fund ’ s cumulative return since inception has passed 4   000 billion Norwegian crowns ($ 511 billion ). One out of four crowns of return was generated in 2017   after a very strong year for the fund  ” Slyngstad said in a statement . “ Again   our equity investments returned strongest with a return close to 20 percent .” The fund ’ s biggest single company investment at the end of 2017 was in Apple Inc ( AAPL . O )  worth 66 billion crowns   ahead of Nestle ( NESN . S ) at 51 billion and Royal Dutch Shell ( RDSa . L ) at 50 billion . Apple was also the biggest single contributor to the fund ’ s returns in 2017   ahead of Chinese tech group Tencent Holdings ( 0700 . HK ) and Microsoft ( MSFT . O ). The fund ’ s size is equivalent to $ 200   000 for every Norwegian man   woman and child . The government withdrew 61 billion crowns during 2017 to pay for public expenses   compared with 101 billion crowns in 2016 .  Slyngstad  earned an annual salary of 6 . 7 million crowns   or roughly $ 855   000   in 2017   while  his  chief investment officer for equity strategies   Petter Johnsen   earned more   with 7 . 4 million crowns . By comparison   the country ’ s prime minister   Erna Solberg   earned 1 . 6 million crowns .
