Guards the rupiah for South-East Asia’s largest economy.
How the BI moves the IDR
A central bank sets the interest rate on its currency. Traders compare that rate with the rates of other central banks; the wider the gap, the stronger the pull of money towards the higher-yielding currency. That is why the minutes before a BI decision are among the most volatile of the month for the IDR. Book I and Book II of the ForeXistenZ trilogy show how to prepare for these days — and when to stay out.
