Why could boasting oil during the current drop in oil demand be good for Saudi Arabia?
The country's funding costs are very low in comparison: 

at an average of  25 per barrel (in comparison: Russia  is funding for 45, the fracking, which is mainly carried out in the United States, costs $ 75 per barrel). So the earnings are above average anyway.

The USA, which has become a serious competitor, should give up market share. Today the United States produces almost as much oil as Saudi Arabia. The Middle East is fighting back with a crowding-out competition.

With state reserves of $ 750 billion, the desert state can easily cope with lower oil revenues over the years.
