3rd decoupling for SA from the emerging markets was the rand. It took place earlier in 2012 onwards due to commodity price declines but never recovered and took another step down from there during 2014 & 15. Again this costs SA as petrol would have been R3 less, maize lower etc. 
Inflation and interest rates would have been far lower and the SA economy would have felt the positive effects of this. Even electricity prices would have been lower as coal and other costs should have been contained better.
Rand not falling out of bed would have helped everyone from farmers to consumers. The cost of government failure here shows how ordinary South Africans pay for mistakes. We pay for this in higher prices, more unemployment, poverty and inequality.
