Decimalization has led to tighter spreads because of the corresponding smaller price increments and movements. For example, prior to decimalization, one-sixteenth (1/16) of one dollar was the smallest price movement that could be represented in a price quote (this is approximately six cents, or $0.0625). With decimalization, the minimum price movement is now one cent, or $0.01, providing a greater number of price levels, and allowing for tighter spreads between the bid and the ask levels for trading instruments.
