The central banks of Norway and Indonesia have become newcomers to the interest rate cut camp. The Norwegian central bank announced it was cutting its main interest rate to a record low of 0.5 percent. That's in line with expectations. Meanwhile, Bank Indonesia lowered its rate by 25 basis points to 6.75 percent, following cuts of the same amount in February and January. Both banks hope the key rate-cut will help fight an economic downturn, prompted by a drop in oil prices, and spur growth in their respective economies.
