In the pre-opening, the European markets traded with gains. On this first day of June, and just a few days before the UK elections, politics remains one of the topics that most attracts the attention of investors. In fact, the issue of European integration is a subject that remains on the agenda, so the interventions of some of the heads of the European Central Bank will be closely monitored. The European Commission presented yesterday a discussion paper on the deepening of economic and monetary union, which proposes that an agreement be reached by 2019 on the two remaining mechanisms to complete the banking union: the single bank resolution fund and the fund European deposit guarantee. In addition, the oil price trajectory has also been monitored at a time when, according to Reuters, concerns remain that production cuts agreed by OPEC are being hampered by the various countries that are excluded from the agreement. Yesterday, the price of this raw material reached a minimum of three weeks, after Libya increased production. In sectoral terms, commodity producers and the banking sector will continue to be the focus of investors.
