China currency devaluation signals endgame leaving equity markets free to collapse under the weight of impossible expectations.
When the banking crisis crippled global markets seven years ago, central bankers stepped in as lenders of last resort. Profligate private-sector loans were moved on to the public-sector balance sheet and vast money-printing gave the global economy room to heal.
