According to the Jakarta Interbank Spot Dollar Rate, the rupiah dropped to a new low of 14,418 against the US dollar on July 3. In the last few weeks, all emerging markets showed an increase in foreign currency volatility. Since April 2018, there has been capital outflow from the Indonesian bond market amounting to almost US$1.9 billion. Solving this problem can be done in two steps. First, sensitivity to capital outflow must be reduced by reducing dependency toward it. Second, capital inflow is needed that is less sensitive to global externalities. Islamic finance may contribute to financial stability, as all transactions must be asset-backed. The principle of risk-sharing between counterparties will help prevent excessive risk-taking. Islamic finance can also help create rupiah stability through its various sharia-compliant instruments, which could attract global investors.
