Heraldo de Madrid - Volatility grips oil market as nervous investors assess Venezuela

Having spiked in an initial reaction to the military operation to apprehend Nicolas Maduro in Caracas, oil prices quickly dropped again on expectations that Venezuela -- which sits on about a fifth of the the world's oil reserves -- will crank up production quickly, adding to an existing supply glut.

But then oil recovered again as investors realised that Venezuela is in no position to make a meaningful impact on oil supply in the short run, even with all the help that US President Donald Trump has promised.

Despite Trump's "obvious desire for US oil companies to ramp up activity in Venezuela, lower oil prices and political uncertainty will frustrate efforts to exploit its vast energy potential", predicted David Oxley, chief climate and commodities economist at Capital Economics.

"It would take years, and massive investment, to bring Venezuela's oil production back to pre-crisis levels," said Ipek Ozkardeskaya, an analyst with Swissquote.

Venezuela has the largest proven oil reserves in the world, at around 303 billion barrels, according to OPEC.

Trump's promise to rebuild Venezuela's crude production capacity with the help of American companies meanwhile sent stocks in oil majors soaring.

In early Wall Street business, Chevron was up nearly five percent, while Exxon rose by around 2.5 percent.

Safe-haven investments gold and silver rose on increased geopolitical risk in the wake of the US invasion.

Prospects of more US interest-rate cuts this year and a booming technology sector meanwhile lent support to equity markets.

The first full week of business for 2026 will see the release of key US jobs data that could play a role in the Federal Reserve's decision-making on borrowing costs.
