During this time, he actively managed the bank’s capital, trading bonds, equities, foreign exchange, commodities and derivatives, while demonstrating strategic leadership. Moving to Barclays de Zoete Wedd in 1995, he spearheaded the setup of the BZW proprietary trading operation. In 1998, Antony joined GA Rate, later acquired by Bipielle International (UK) Limited in late 2000. Here, he managed a hedge fund with discretion, employing strategies that would later be mirrored by Sanctum FI LLP.

Departing from Bipielle in 2002, Antony co-founded Sanctum FI LLP, where he continues to serve as a partner. He is an accomplished finance professional with a proven track record in managing a fixed income relative value fund, trading both corporate and government bonds, foreign exchange, and derivatives. Beyond his roles in finance, Antony actively contributes as a board member of ACTB Bank in Sierra Leone and holds director positions at Truestone Ark Ltd, Truestone Impact Investment Ltd, and ESTA414 Limited.
