Brent crude sank below $100 a barrel for the first time in nine months on Tuesday amid a wider commodities rout, with investors making a beeline for the exits after recent weak data from China and the United States fuelled worries about oil demand.
A dismal global economic outlook dragged gold down to a more than two-year low and shaved over $2 off oil prices earlier in the session. While commodities recouped some of the losses later in the day, shaky investor sentiment kept a lid on prices.
Brent crude for June delivery dropped $1.10 to $99.53 per barrel by 0653 GMT, after falling to as low as $98.00 -- the lowest since July 2012. Brent, which dropped for a ninth session out of eleven, has shed more than $6 since April 9.
U.S. crude for May delivery fell 89 cents to $87.82 a barrel, after hitting a low of $86.06 -- its weakest since December 2012. The prices were set for their longest losing streak also since December.
"Fundamentals were not strong at the start of the year but yet (investors) focused on all the bullishness in the market. But as the year went on, it got steadily more bearish and I think (the China data) was the final nail in the coffin," said Tony Nunan, an oil risk manager at Mitsubishi Corp in Tokyo.
