BRL/HKD: what to know
The BRL/HKD rate shows how much HKD you get for 1 BRL. Right now, 1 BRL buys 1.5316 HKD at the mid-market rate. In the other direction, 1 HKD is worth 0.6529 BRL.
In the short term BRL is driven mainly by commodity prices and central-bank policy, while HKD responds to its peg to the US dollar.
The Brazilian Real (BRL) is issued by Central Bank of Brazil. The real was introduced in 1994 to end hyperinflation; the plural is “reais”. The Hong Kong Dollar (HKD) is issued by Hong Kong Monetary Authority. Most banknotes are issued by three commercial banks, not a central bank.
Use this mid-market figure as your benchmark: compare it with the rate your bank or broker quotes, and the difference is the margin you would pay.
