South Africa’s JSE All Share Index rose almost 5% and the rand strengthened after the Democratic Party’s US midterm victory and market hopes for a quicker end to the US-Iran conflict. Brent crude fell below $100 a barrel and was down about 20% for the week; gold and several South African mining shares also advanced.
Lower crude prices can reduce energy and freight costs for feed supply chains, while a firmer rand lowers the local cost of imported commodities. These are market-wide price effects driven by changing expectations about conflict and US politics, not by new agricultural supply information.
After 312 past bearish macro events, Crude Oil (Brent) moved a median -1.7% over 5 sessions (38% higher; middle half -5.4% to +2.3%), and -1.7% over 20.
