The global uncertainty has been on a rising trend and has gone up a few notches in the last week, said India's Chief Economic Advisor V Anantha Nageswaran adding that countries need to live with this, not just this year but for the next year and beyond. Nageswaran said that the key thing to do when you are facing uncertain times is to make sure that you have margins of safety in your operations, whether it is for corporates or for investors.
