Several hedge funds named last week in the Greek press have denied shorting the country’s debt, while others declined to comment. Separately, a Goldman Sachs executive told British lawmakers that it did “nothing inappropriate” in arranging now-criticized debt-swap deals for Greece, according to Bloomberg News. Brevan Howard issued an investor letter shortly after the reports came out, saying it had no exposure to Greek debt or the credit default swaps that insure against its default since mid-December.
