Oil prices fell to the lowest levels since last year, triggered by concerns over excess supply of crude oil and weak demand in uncertain economic growth.
Oil prices dropped to its lowest level since October 2017 at a time when crude oil extraction in the United States, Russia and Saudi Arabia remains high and global growth expectations have declined, partly due to the US-China trade dispute.
"It's true that the growing global supply of crude oil combined with the worrying signs of declining demand has spelled out a catastrophe in oil markets," said FXTM research badyst Lucman Otunuga.
There were different trends in global stock markets. US stock market indices fell, partly driven by concerns over lower oil prices and weak global growth. The London Stock Exchange fell, while the Frankfurt and Paris Stock Exchanges rose modestly.
The drop in oil prices was echoed in stock markets, with prices for oil giants Chevron, Royal Dutch Shell and Total falling by at least 3%.
