Venezuela's day of reckoning?Monday looks like crunch day for Venezuela, with a planned Caracas meeting for creditors to discuss debt restructuring, a New York bondholders' meeting that could lead to a default announcement, and new EU sanctions. Combined, the events point to a day of reckoning for the OPEC-member nation, and a tighter squeeze on its beleaguered President Nicolas Maduro and his socialist government. Monday may be the day that Venezuela's house of cards comes tumbling down.
