The Ibex 35 has started this Tuesday's session with a rebound of 0.11%, standing at 16,907.3 points at 9:00 a.m., in a context of rising Brent crude prices, which advances to 101.1 dollars, well above the 72 dollars at which it was moving before the attack against Iran by the United States (USA) and Israel.
Minutes after the bell, the selective expanded gains and registered a rise of 0.43%, reaching 16,963.7 points.
The price of Brent experienced a sharp decline yesterday after the president of the United States (USA), Donald Trump, decided to postpone for five days the attacks against Iranian power plants and assured that he had held “very solid conversations” with Tehran to try to close an agreement that would end the war.
However, the president of the Iranian Parliament, Mohamed Baqer Qalibaf, has rejected any type of dialogue with Washington and has attributed Trum's announcement about the imminence of a pact with Tehran to an attempt to artificially alter crude oil prices.
“There has been no negotiation with the US. They use fake news to manipulate the financial and oil markets and thus get out of the quagmire in which the US and Israel are trapped,” he affirmed in a message published on social networks.
Iran's denial to Trump and crude on the rise
After the denial by Iranian authorities of Trump's words, oil has resumed the upward trend. Last week, the Brent barrel exceeded 119 dollars after Iran attacked a liquefied natural gas complex in the Qatari town of Ras Lafan, in response to a previous Israeli bombing on one of the main Iranian gas fields, the South Pars field.
In this context, Wall Street closed yesterday's session with widespread gains, with increases of 1.4% in the Dow Jones and 1.2% in the Nasdaq, while the main Asian markets are registering strong increases this Tuesday.

The oil, in full escalation
Amidst this climate of tension, the Brent barrel, a benchmark in Europe, rose by 1.1% at the opening of the Old Continent's stock markets, to 101.1 dollars, while West Texas Intermediate (WTI), a benchmark in the US, advanced by 1.62%, to 89.65 dollars.
Crude oil prices, very volatile in recent days, are conditioned by the fear that the conflict will last longer than expected and by incidents in the Strait of Hormuz, where several oil tankers have been attacked since the start of the offensive.
The Strait of Hormuz is a strategic passage through which transits around a fifth of the world's maritime oil trade, in addition to a significant volume of liquefied natural gas and fertilizers.
The practical paralysis of maritime traffic in this area has forced Gulf producers to cut their pumping, which in turn is feeding the escalation of crude oil and natural gas prices.
In the foreign exchange market, the euro was trading for 1.1607 “greenbacks”, while the yield of the ten-year Spanish bond fell to 3.499%.
