Ng was speculating in futures contracts on the
Hong Kong Futures Exchange through two Panamanian-registered companies when the
October 1987 global stock market crash began; his paper losses reportedly reached HK$1 billion. At first, Ng refused to pay, claiming to be protected by the limited liability of the companies through which he had traded. This led to the collapse of the futures exchange; trading was also halted on the
Hong Kong Stock Exchange for four days. An investigation by the Commercial Crime Bureau of the
Royal Hong Kong Police revealed that Ng had avoided required
margin calls through collusion with one of his brokers. Instead, a deal was worked out which saw Ng repay HK$500 million, with Hong Kong taxpayers providing the rest of the funds needed by the Exchange through a government bailout. In the end, Ng and his father were able to successfully take advantage of squabbles within the Yeo family to buy up 86% of YHS' stock. Their battle to gain control of the company was later described as "one of the most colourful take-over struggles in Singapore history" and led to YHS' transformation from a food company to a
luxury real estate developer. The Sino Group also spun off their hotel interests into a new company,
Sino Hotels, in that year; Ng became chairman of the board of the new company as well from its inception. In early 1997, under Ng's direction, Sino Hotels made several acquisitions, including an 80% stake in the local branch of the
Conrad Hotel for HK$2 billion. Ng also predicted that office properties would perform well during that year. For the latter six months of that year, Sino Hotels reported a 66% fall in net interim profits and 80% fall in operating profit, which Ng attributed to lower contributions not just from hotels but from the company's Fortune chain of Chinese restaurants as well. However, the Conrad proved to be a resilient investment, with the average room rate increasing by 14.7% during the months in question.
