The dollar resumed its rise on Wednesday, surging to new 13-month highs and upping pressure on commodities, emerging markets and global stocks, though the Turkish lira managed out to eke out a second day of gains.
Wall Street futures pointed to a sharply lower opening.
The lira, a big focus for markets in recent days, bounced as much as 8 percent as authorities tightened the screws on foreign investors aiming to short the currency. But having firmed beyond 6 per dollar, most of its early gains fizzled out.
