Before Prime Minister Alexis Tsipras gets any euro zone deal on Greece’s public debt, he could make good on his promise of a permanent mortgage moratorium. That would inflict pain on the country’s banks – but ultimately force them to restructure.

Currency market still scarred by Swiss trauma

Brutal swings seen just after the Swiss central bank suddenly abandoned its franc cap have faded. But price signals and perplexing moves suggest the extraordinary gyrations left their mark. Singapore’s surprise easing and continued Swiss official musings will add to the jitters.

China political investment bubble has new antihero

Newly merged brokerage Shenwan Hongyuan is worth $41 bln – more than Charles Schwab. Its peers trade at triple the valuations of most global securities houses. The mania is part excitement over China’s stock markets, and part misguided belief the state can keep things afloat.
