The government may use its economic assessment for November to warn that the downside risks facing the nation's economy are increasing, a senior official of the Cabinet Office indicated Friday.

"The real economy is not deteriorating rapidly, but various risk factors have become actual," said Yuzo Kobayashi, vice minister for economic and fiscal policy at the Cabinet Office.

Kobayashi declined to say whether the government will downgrade its economic assessment, scheduled to be released Tuesday.

He numbered deceleration in the U.S. among the downside risks that have become a reality.

In October, the government left its overall economic assessment unchanged for a third straight month, stating that the economy was improving.

It acknowledged, however, that Japan's recovery had slowed and that the downside risks had increased.
