Jornal Do Brasilia - Oil rises as Trump comments roil energy markets

Doubts surrounding US President Donald Trump's claim of an "energy ceasefire" between Ukraine and Russia, following his surprise announcement of a deal to buy diesel from Moscow, further unsettled investors.

After a mixed showing for stocks across Asia, Europe's main indices rose in midday deals, with the car sector lifted by the European Union's announcement that it will cap imports of hybrid vehicles from China in a bid to avert a trade war.

The dollar was higher against most currencies ahead of key US inflation data this week, which will be pored over for clues on when the Federal Reserve will likely raise interest rates once more in a bid to tame elevated inflation.

"Oil remains well bid above $100 after strikes on Saudi Arabia's Riyadh airport over the weekend, whilst efforts to secure a Russia-Ukraine energy truce were muddy," said Neil Wilson, a strategist at Saxo UK.

Meanwhile, "a US deal to purchase some Russian diesel is a drop in the ocean", he added.

Russia on Monday refused to say whether an agreement had been reached with Ukraine to halt attacks on energy infrastructure, a day after Trump sowed confusion with his unilateral announcement that an "energy ceasefire" had been reached.

Trump also called for Ukraine to "get a new leader" after Volodymyr Zelensky slammed Washington's easing of Russian diesel sanctions, as Trump grapples with high fuel prices weeks before midterm elections in the world's biggest economy.

Saudi Arabia's energy minister acknowledged meanwhile that the kingdom's infrastructure and resilience had been tested following a wave of deadly attacks by Yemen's Houthis.

The weekend strikes marked a sharp escalation in the Yemen war, where Saudi Arabia has long supported the internationally recognised government.

Also in view this week for markets is the start of the corporate earnings season, with US banking giants JP Morgan, Goldman Sachs and Bank of America due to report.

Tech giants will follow later in October and November, with traders keen to get an idea on the outlook for the AI sector as it invests vast sums despite growing concerns over the technology.

Microsoft co-founder Bill Gates warned Sunday that unregulated artificial intelligence posed a growing threat and predicted an escalation in AI-powered cyberattacks in the coming year.

He said that while the risk of AI "getting out of control" remained years away, the immediate concern was "bad people" using existing systems without safeguards.

"The front that we'll probably see most dramatically in the next year is cyberattacks," Gates told ABC News.
