If I recall, I saw a promotion rate somewhere at 2.88% or around 3% thereabouts. Of course, for HNW individuals, there might be better rates (I guess ?) In a local context, I believe most would use it to buy REITs because the dividend are more predicatable and able to cover the interest payment on the margin facility. And the volatility of a "Good" Brand name REIT(e.g parkwaylife) is usually lower than other SGX stocks, this is to reduce the chances of a huge margin call. But in exceptional times such as financial crisis, anything could happen, so be prepared. Using Margin for US counters are not very effective unless one aims for huge capital gains. But in this case, then it might be better to just go for CFD trading because holding margin for a long term will eat into your long term returns. Plus, dividends from US counters are taxed at 30%.
