lol yes, but CBs always only ever do a half arsed job of intervention, probably because deep down they know it's doomed to fail and market forces will win out at the end of day and find true value of the currency.
I think CBs only try just to give the public the impression they are doing something rather than nothing.
They'll probably do what CBs always do in the end and devalue the currency themselves or, the modern way is just to print more and devalue that way.
