1) Interest rates in Thailand are determined by the Bank of Thailand, which uses the 1-Day Repurchase Rate (1-Day Repo Rate) as a policy tool. The 1-Day Repo Rate was recently increased from 1.18% to 1.25% due to high demand for funds. 2) Two charts show the relationship between the 1-Day Repo Rate and the SET Index from 2003 to 2009. During this period, the 1-Day Repo Rate and SET Index generally moved in opposite directions. When the 1-Day Repo Rate increased, the SET Index tended to decrease, and vice versa.
