The president is spending the weekend at his family's estate in the US state of Maine after a rocky week for markets around the world.
'I can assure you that there are many of the president's advisers who are keeping a very close eye on all of the market activity and making sure that policies are put in place to keep our economy strong and growing,' White House spokeswoman Dana Perino told reporters.
Asked whether the president himself was closely monitoring the situation, Ms Perino said: 'I can assure that on any issue, especially an issue like this, the president would get regular updates.'
