Banga left Gulf in 1989, and became an early partner in Noble Group Limited in cooperation with Richard Elman, helping to establish and lead Noble Chartering Limited. Noble Group was a supply chain manager of agricultural, industrial and energy products, and Asia's largest commodities trader. Following Noble Group’s Hong Kong listing in 1994, Banga served as Vice-Chairman of the Group, and despite a low public profile, is widely credited as the driving force behind much of Noble’s success. His 21 years with Noble, as it rose into the Fortune 100, made Banga a wealthy man and earned him a place on the Forbes billionaires list as one of Hong Kong’s 40 richest men. In 2010 Banga stepped down as Vice-Chairman of Noble Group Ltd, but remained on the Board as Vice-Chairman Emeritus. In 2011 he purchased the Noble Group’s ship management arm, Fleet Management Limited, from Noble. He severed his ties with Noble in 2012.
