The protests in Hong Kong have brought a mood of growing pessimism about the city's economic situation. In an earlier interview with CNBC, the President of the American Chamber of Commerce (AmCham) in Hong Kong said: "The real concern here, which we've seen slight signs of, is that people are moving their companies and their money in greater numbers to Singapore." Goldman Sachs estimates as much as four billion HK dollars has moved from HK dollar deposits to Singapore as of August. According to AmCham Hong Kong's latest survey, 46-percent of the surveyed member companies are pessimistic about Hong Kong's long-term prospects, up from 34 percent in AmCham's July poll. 61 percent have seen business affected to a medium and great extent. 24 percent are considering scaling back or moving away from Hong Kong. Singapore remains the top destination for backup plans.
