Opening Markets Raises Stock Prices And Increases Investment

October 13, 2000

When Latin American and Asian countries opened their stock markets to foreign investors in the late 1980s, capital investment surged and economic growth rates climbed.

According to a recent study, opening up these markets increased the supply of foreign capital and allowed greater risk sharing between domestic and foreign partners.

These factors lowered the cost of equity and boosted private investment.

  • During the eight months preceding the liberalization of stock markets, stock prices rose by an average of 3 percent per month in anticipation, surging a total of 25 percent due directly to liberalization.
  • The 20 percent cost of equity typical of a closed market was likely to drop to 15 percent once foreign investment flowed in.
  • Following liberalization, the average growth rate of private investment was 23 percentage points higher in the first year, with 27 percentage points and 17 percentage points in the second and third years.

The author notes that the surge in capital and private investment is temporary. After about 4 years, private investment returns to pre-liberalization rates. Nevertheless, the three years of strong investment growth is extremely valuable in previously stagnant economies.
