Father of Grexit: "Disaster" for the eurozone if Greece leaves

Greek ongoing negotiations isolate currency investors on Thursday, indicating their unwillingness to take bold positions deadlines for a deal have come and gone, leaving the euro unchanged against the greenback.
Even optimistic US economic data failed especially to help put dollars. US consumer spending leftover biggest increase in nearly six years.
Earlier, the Swiss franc fell to a 10-day low against the euro after the head of the Swiss National Bank said it was "significantly overvalued" and that the SNB will continue to intervene in currency markets.
In midday trading in New York, EURCHF was up 0.25% at 1.0489.
The inability of the Greek authorities to reach a deal with creditors would likely cause massive infusions in Swiss currency to be a safe haven.

Some analysts believe that a deal will be reached and the direction of the euro against the dollar may again be driven by fundamental factors. With ultra-loose monetary policy in the euro area and the US, but the expected increase in US interest rates, it means that the euro will depreciate.

Neil Mellor, currency strategist at Bank of New York Mellon in London, said the euro will fall if a deal for Greece, as investors used it to carry trades.
What is quite clear is that whenever you have a chance to deal the euro takes down, and every time there is disappointment reversed.
