"If it (the sequester) goes through it would have a 1 percent drag on gross domestic product and unemployment will go up," Tony Nash, managing director at IHS Consulting, told CNBC Asia's "Squawk Box" on Monday.

"If the sequester kicks in and some other tax issues kick in, you're also looking at about 1 percent being added to unemployment, so you're looking at a lot of risk in the first half of the year," he added. The U.S. unemployment rate is 7.8 percent, with the latest monthly job numbers due this Friday.
