Aug 11 (Reuters) - U.S. stock indexes were set to open little changed on Friday, with the S&P 500 on track to post its biggest weekly loss in nine months, as investors remained cautious on heightened tensions between the United States and North Korea.
U.S. President Donald Trump, in his latest warning to North Korea, said military solutions were "fully in place" and referred to American weapons as being "locked and loaded" should the nuclear-armed nation act "unwisely".
The tensions, since Trump made his "fire and fury" comments on Tuesday, have wiped out nearly $1 trillion from the global equity markets.
"The escalation of the geopolitical situation between the U.S. and North Korea is beginning to rattle investors' nerves as was witnessed in the VIX index yesterday," said Peter Cardillo, chief market economist at First Standard Financial.
"The overall 'Fear Factor' is the markets worst enemy that will feed on itself, leading to increased hedging."
On Thursday, the CBOE Volatility Index, a barometer of expected near-term stock market volatility, closed at its highest since the U.S. presidential election.
Helping offset the geopolitical tensions was weaker-than-expected consumer price data for July, pointing to benign inflation that could make the Federal Reserve cautious about raising interest rates again this year.
The Labor Department said its Consumer Price Index edged up 0.1 percent last month, which was below the 0.2 percent rise expected by economists polled by Reuters.
The data comes amid tepid inflation that has remained below the Fed's 2 percent target, despite low unemployment.
