Please take a moment and consider the implications of a national lockdown. As of a certain moment, international airlines will no longer fly to South Africa. The airlines neither want to risk their staff, nor do they have passengers that seek entry to South Africa. As a result, any flight from South Africa will be a one-way flight - with no passengers on the leg to South Africa. This makes these flights unprofitable and the airlines will cancel their regular flight schedules.
Government has announced total lockdown of South Africa.
In our assessment, the lockdown will not be of short duration. Common sense and experience in other countries has shown that there will be undesirable consequences. If a large segment of the population is unable to work, people will go hungry as soon as their limited reserves are depleted.
When hunger becomes a large scale problem, society typically breaks down. Looting and other forms of crime become a natural development.
