Asian market investors appeared disappointed with a predictable outcome of the Organisation of Petroleum Exporting Countries (Opec) meeting in Vienna on Thursday (April 25). The much-anticipated meeting with Russia did adhere to expectations of an oil supply cut, but no decisions were made on controlling the increasing supply of US shale.

The OPEC meeting concluded with a confirmation of extending the cut in oil supply by a further nine months beyond June. The Brent crude rally prior to the decision implied that investors were either expecting a longer extension or a tighter oil supply.

The Brent Crude price fell by 0.39% to $51.26 (£39.70).

Following the end of the OPEC meeting, markets will now closely watch the outcome of former FBI head James Comey's testimony, which concerns allegations against US President Donald Trump's involvements with Russia. The testimony, scheduled to commence after Memorial Day (May 29), might have serious repercussions for the Trump administration.
