Macao's broad money supply continued to grow in September with a stable share of patacas, as broad monetary supply M2 grew 10.3 percent year-on-year to 626.4 billion patacas (about 77.75 billion U.S. dollars), the special administrative region's monetary watchdog said here on Monday.

According to statistics by the Monetary Authority of Macao, currency in circulation grew 3.2 percent month-to-month whereas demand deposits dropped 5.3 percent, thus M1 decreased 3.6 percent from one month earlier.

Meanwhile, quasi-monetary liabilities rose 1.4 percent. The sum of these two items, i.e. M2 increased 0.8 percent to 626.4 billion patacas. On an annual basis, M1 and M2 grew 13.1 percent and 10.3 percent respectively.

The shares of pataca, Hong Kong dollar, renminbi and U.S. dollar in M2 were 31.0 percent, 51.7 percent, 4.3 percent and 11.0 percent respectively.
