[11] He later served as the minister of finance from 20 October 1986 to 23 February 1997,[4] overseeing the country's substantial oil and gas revenues through the BIA,[12] where he also held the position of chairman.Amedeo quickly became the largest private conglomerate in the nation, with 27 companies specialising in non-hydrocarbon industries like infrastructure (port management, electrification, and telecommunications), tourism (The Empire Brunei and Jerudong Park), real estate, and finance.The establishment of an export zone in Muara in May 1994, the partial privatisation of port management, the lowering of import duties on 650 goods and equipment in April 1995, and the opening of a container terminal in early 1996 were among the noteworthy milestones that followed under his direction.Brunei's economic prospects were bolstered by the discovery of a large gas resource and its categorisation as a developed country by the World Bank in 1996, despite stalled investment outside of petroleum due to antiquated tax regulations.[14] Following the 1997 Asian financial crisis, the sultan ordered external audits of BIA's finances, revealing that Jefri Bolkiah had allegedly embezzled $14.8 billion.[17] Shortly thereafter, on 31 July, the sultan stripped him of control over the country's investment arm and telecoms empire, following widespread reports of significant financial losses in the conglomerate he managed.[4] Despite this, the BIA accused Jefri Bolkiah of failing to disclose all his accounts and allowing withdrawals from frozen funds,[20] leading to renewed legal action.[26] The Privy Council dismissed Jefri’s claims that he had the right to retain certain properties, calling his arguments "simply incredible,"[27] and ruled in favour of the Brunei government and the BIA, ordering him to return the remaining assets.[31] On 3 March 1997, Shannon Marketic, a former Miss USA, accused Jefri Bolkiah, the sultan, and others of luring her and several women to Brunei under false pretences to join a harem, alleging abuse by members of the royal court.[32] She claimed that she was hired to make a promotional appearance for the sultan in 1996, but upon arriving in Brunei, her passport was confiscated, and she was detained for 32 days while performing in an Asian male discotheque, where she was allegedly sexually harassed by some men.[33][36] In 2006, Jefri Bolkiah initiated legal proceedings in both the UK and the U.S. against his former advisors, barrister Thomas Derbyshire and his wife Faith Zaman,[37] accusing them of misappropriating funds.[38] The couple, who had worked for him since 2004 and managed several of his companies, were accused of diverting proceeds from property sales and charging personal expenses to corporate credit cards.[43] However, Judge Ira Gammerman deemed these details, along with Jefri's wealth, multiple marriages, BIA's challenges to his credibility, and the outstanding British arrest warrant, irrelevant to the case and barred them from being mentioned in court.[60] Jefri Bolkiah played for Brunei's national polo team, which defeated Malaysia 7-4 in the Division B: 0-2 goals category to win a gold medal at the 30th SEA Games.[13] The boat gained notoriety for its contentious moniker, presumed to have been chosen by him, which garnered significant attention, was regarded as unusual, and frequently caused embarrassment during public appearances.[71] Jefri Bolkiah was appointed the wazir title Duli Yang Teramat Mulia Paduka Seri Pengiran Di-Gadong Sahibul Mal with the consent of the sultan on Wednesday afternoon, 8 November 1979.
