The Asian Development Bank (ADB) reports that Asia infrastructure investment is sourced primarily from the public sector (especially since the end of World War Two), followed by official development assistance and private participation in infrastructure. With public sector budgets being stretched, private institutional investors are increasingly providing more financing sources from privatisations (in the 1980s) and public-private partnership schemes (in the 1990s). These two capital sources help investment in Asia infrastructure and capital projects to reach 7% annually, projected to reach an annual volume of about $5000bn by 2025.

Public capital comes from central, regional, local and other government institutions, plus national development banks and multilateral development banks. Private capital is provided in two main forms: corporate finance (on balance sheet, from the resources of infrastructure companies) and project finance. In Asia, bank loans still dominate infrastructure project finance, and public sector banks play a major role, especially in China.


Across Asia, spending on infrastructure (as a percentage of GDP) varies. The first difference is geographic. The highest spender is China, with South Korea as the middle spender and then south-east Asia being the lowest spender. Underinvestment in infrastructure and poor maintenance of existing infrastructure are economic growth constraints and lead to infrastructure bottlenecks, in turn attracting less inward FDI, which creates jobs. Casual research reveals a great many Asian infrastructure projects that are either suspended, aborted over decades, or suffering from frequent breakdowns and accidents when funds are focused on the less strategic areas, depriving local communities of badly needed social benefits and impacts.

Second, Asia infrastructure spending differs by income. Low-income countries experience significantly higher infrastructure needs (12.5% of GDP) than middle-income (8.2%) and high-income (2.3%) countries. An estimated spending gap of $1000bn per annum is projected just for developing economies alone.

The ADB also found that 32 developing Asian economies would need infrastructure investment of $8200bn (in 2008 prices) between 2011 to 2020. About 50% of investments would go into energy, about one-third into transport (mostly roads), and the rest into telecommunications, water and sanitation. Two-thirds is needed for new capacity and one-third for maintenance and the replacement of existing assets.

How will Asia infrastructure investment evolve? Private capital investment is traditionally very dependent on bank loans. Expect more non-bank financial institutional players such as pension funds, insurers, investment funds and sovereign wealth funds. Also, there may be a greater use of securitisation and capital markets in infrastructure finance together with further development of bond markets.
