Indonesia's stocks and currency skidded on Friday after Moody's lowered the country's credit rating outlook, the latest jolt for Southeast Asia's largest economy, wiping about $120 billion off its equity market in a turbulent start to the year. International investors have reacted nervously to President Prabowo Subianto's attempt to ramp up growth to 8%, as concerns over fiscal health and central bank independence cool sentiment on Indonesia. The benchmark Jakarta Composite Index lost nearly 3% while the rupiah dropped as much as 0.36% to 16,885 a dollar, its lowest since January 22 and down 1% for the year. Stocks have fallen 4.7% for the week so far, after last week's decline of 6.9%.
