At this morning’s Newsmaker “Thriving in the New Global Economy,” Alcoa CEO Klaus Kleinfeld and McKinsey Global Managing Director Dominic Barton told Chrystia their outlook for the world economy. From his perch atop one of the world’s leading aluminum producers, Kleinfeld was “really positive” about global growth prospects. Coming off a strong year in which aluminum demand rose 13 percent, the Alcoa chief forecast that aluminum demand will grow at a slightly slower rate of 12 percent this year thanks to China’s efforts to slow down its economy:

While also bullish on global growth, Barton noted that there was a sense of fragility in the world economy that concerned him. Specifically, the McKinsey head was worried about the government’s response to looming inflation, which he predicted would rise to the range of 6 to 7 percent. Mounting government debts and the rising cost of capital, which Barton believes will be “up fairly significantly” as savings rates in the emerging markets decline, will exacerbate the inflation problem:

“We’re in a slack period if you just look at what the cost of money is. It’s an incredibly unique period. I think that’s going to go away, and that’s going to make it challenging.”
