SINGAPORE M-1 MONEY SUPPLY UP 3.7 PCT IN DECEMBER Singapore's M-1 money supply rose 3.7 pct during December to 9.82 billion dlrs, after a 2.0 pct increase in November, the Monetary authority of Singapore (MAS) said. M-1 growth for calendar 1986 was 11.8 pct compared with 4.0 pct growth over the year ending in November. MAS said in its latest monthly statistical bulletin the December increase was largely due to seasonal year-end demand.

Currency in active circulation rose to 5.03 billion dlrs in December from 4.85 billion in November and 4.74 billion a year earlier. Broadly-based M-2 money supply rose 1.6 pct to 30.95 billion dlrs during December after a 1.7 pct rise in November, bringing year-on-year growth to 10.0 pct for the year ending in December against 10.2 pct for the year ending in November.
