1. Markets rattled by North Korea: Global stock markets dropped Tuesday after North Korea fired a missile over Japan.

The closely watched VIX (VIX) volatility index spiked by 24% and U.S. stock futures were off by between 0.6% and 1%.

In Asia, South Korea's benchmark Kospi index closed 0.2% lower, after falling as much as 1% in morning trading. Japan's Nikkei sank 0.5%.

Markets in Europe opened sharply lower. Stocks in London and Paris slumped 1.4% while Frankfurt's DAX shed 1.7%.

Investors flocked to perceived safe havens. Gold added 1.2%, while the Japanese yen and Swiss franc gained over 0.8% against the dollar.

2. Harvey chaos: Harvey caused more havoc in Texas overnight, with forecasters saying a reprieve won't arrive until week's end at the earliest.

An ExxonMobil (XOM) oil refinery near Houston was damaged by the remnants of the hurricane, and the company warned chemicals could be released.

Still, the scale of damage Harvey will bring is far from clear.

AIR Worldwide, a risk modeling company, estimated Monday that insured losses from just the winds and storm surge could reach more than $2.3 billion. An earlier estimate from the analytics firm CoreLogic showed that Harvey could cause as much as $40 billion total in damage.

America's Corporate giants are making big contributions to disaster relief organizations to help victims the storm.
