LONDON, Nov 18 (Reuters) - Glencore, the world's biggest commodity trader, posted a 42 percent jump in nine-month net profit to $2.5 billion on Thursday, mainly due to higher commodity prices, and cut its debt burden.
Privately held Glencore, which is preparing to become a listed company after issuing a $2.2 billion convertible bond last year, said liquidity fell to $4.6 billion in the third quarter from $6.5 billion in the second quarter, but still beat a target of $3 billion.
Swiss-based Glencore said third-quarter net profit of $979 million, up from $677 million in the second quarter, was the highest since the onset of the global downturn in 2008.
Net debt rose to $15.2 billion from $13.6 billion in the second quarter, according to a statement released to bondholders and made available to Reuters by a source who had access. (Reporting by Eric Onstad; Editing by Will Waterman)
