Construction

While advanced economies are still facing high levels of unemployment, more than a billion people in emerging markets are experiencing advancing standards of living.

As these emerging economies - especially China and India -grow, there is a strong trend toward urbanization. People are leaving the countryside for the cities in droves in order to reap the promise of the global economy. This secular process alone places huge demands on the existing infrastructure.

This growth is also boosting manufacturing and energy needs. China has surpassed the United States in both car production and energy consumption. And India's Tata Motors Ltd. (NYSE ADR: TTM) launched the cheapest car in the world, the Nano, which costs roughly $2,500. The critically acclaimed vehicle's mass appeal and affordability is creating additional congestion on India's famously overcrowded streets. Adding more fuel to the global-demand fire, most emerging economies implemented a strong dose of infrastructure spending within their budgets as a result of the global financial crisis of 2008.

The result of all that infrastructure development, urbanization and increased consumer affluence is a myriad of new road, bridge and building construction, additional urban development, and stepped-up production of cars, home appliances and other consumer goods. All of these developments require two key ingredients to become reality: Steel and energy.
