Three stories this week from the Philippines build a complex picture of a booming cement industry. San Miguel purchased a 25% stake in Northern Cement, Lafarge Republic announced its capital expenditure budget for 2013 and the country's on-going price probe reported on its progress.

San Miguel's entry into the market should raise the most interest since its president stated that the company intends to spend US$750m on the construction of three cement plants. Each plant will have a cement production capacity of 2Mt/yr with construction timed to start in 2013 and finish by the end of 2015.

This level of investment, if it happens, surpasses the last major build announcement in the Philippines. In May 2013 Holcim released details of a US$550m plant in Bulacan with a capacity of 2.5Mt/yr. Some indication of the viability of San Miguel's plans may be gleaned from the comparative costs of the projects. San Miguel's plans will cost US$125/t of installed capacity, less than half of Holcim's US$220/t. Possible reasons for this difference may lie in San Miguel releasing the wrong figures or a reliance on lower build quality. However San Miguel's sheer size - its net income was US$2.25bn in 2011 - may itself herald the start of a major player in the domestic cement industry.

Meanwhile the Department of Trade and Industry (DTI) has continued to investigate why the price of cement has risen since 2012. Currently prices are about 5% above the suggested retail price for cement. Cement producers blamed the increases on a higher cost of coal.

The Philippines is currently experiencing massive cement sales increases. In 2012 sales rose by 17.5% to 18.4Mt from 15.6Mt in 2011. With a total capacity of 21Mt/yr and a capacity utilisation rate of 85% in 2012, this growth looks set to continue in 2013, as confirmed by more rises in sales in the first quarter.
