World's largest sovereign wealth fund could fall from $2 trillion to 0, warns CEO

Norway's $2-trillion sovereign wealth fund, the world's largest, could lose its entire value in a market collapse, its CEO Nicolai Tangen warned. Given current global conditions, "it is not completely improbable" for the fund to disappear, he said. The fund invests proceeds from the country's oil and gas production in stocks, property and renewable energy projects abroad.
