The rupiah closed 0.04% weaker at Rp18,089 per US dollar on November 6. A currency analyst attributed the decline to tanker attacks and escalating security risks around the Strait of Hormuz and the Red Sea, which raised concerns about disruptions to oil shipments.
Threats to key oil routes can tighten crude supply and lift energy costs, including freight and agricultural input expenses; the associated risk aversion can also pressure the rupiah. Higher fuel costs would be inflationary for feed supply chains.
