market. the shanghai and hong kong indexes both closing at their lowest levels in years. rob mcbride is in hong kong with more. >> reporter: this has been an horrendous end to a herren douse couple of weeks. the fall brings losses for the week to nearly 9%, and 21% since last december. that is very much bear market territory. and they are predicting it could fall further. last week we saw measures by the authorities to try to stop the fall, we saw those measures being lifted. they clearly weren't working. if anything they were making the situation worse. despite that the selloff has continued this week, and people are wondering what the wider impact is going to be on the chinese economy. next week we're expecting

all-important gdp figures to show what the growth rate was doing in the last quarter of 2015. it is likely to show continued slowing in the chinese economy. the big question is will the authorities allow that to be a soft landing or a hard one. on the evidence of the last couple of weeks, things are starting to feel pretty bumpy now. >> patricia sabga joins us now. and the numbers opening down more than 300 points. looking live at the board right now, they are still down more than 300 points. no corrections or changes. why? >> this is the momentum from that selloff in china, and oil prices dipping below $30 a barrel. and we saw that retail sales were down in december. now keep that in mind, december christmas shopping season, not a

great reading there. but the other reason is you have to keep in fine that two-thirds of u.s. economic growth comes from retail spending, so that signals that american consumers are not spending as much as they need to, to grow the economy. >> $660 a year, consumers save in their pocketbook because gas is so cheap. but what does this mean for the 401k. >> we saw an graphic on oil prices. and some analysts are predicting it to go as low as $15 a barrel. and this is indicative of a global economic slowdown. so if you are talking about in terms of your 401k, for example, how are exquestionties going to

do? equities have been overpriced for a very, very long time some analysts say. about half of the sales comes from selling goods overseas. the dollar is very strong right now, making u.s. goods relatively expensive to other goods. so that will hut -- hurt equities. energy stocks are being hit. you have the sector of sanctions coming off of iran pumping even more oil into a market already awash in oil, which will drive prices even lower, and there is the big risk of deflation. and that is terrifying to economists, bhauz -- because when people think prices will go lower, they are going to wait for a lower price and that grinds economic activity to a halt. waning demand from china, and

lower pricing across the board, that filters out to all of the countries that export to china, and lowers the volume of overall global trade, and the question is to what extent is this going to hit the united states? we're starting to see weakness in exports and retail sale and we just got the empire manufacturing index, and that was also weak. >> patricia sabga thank you. and wal-mart announcing it is going to be closing more than 200 stores worldwide. more than half of those closures will take place here. 1600 workers will be effected globally. the ceo telling investors the company would reevaluate store closures. and goldman sachs has reached a $5 billion deal with the justice department.

pentagon came out and said they were testing 400 samples that they had to figure out what went wrong. they showed the live anthrax that they thought had been effectively killed, the spores. they showed how it had been shipped. they showed that it was liquid, not easily inhaleable, that the public wasn't at risk, and it was a fraction of a teaspoon wrapped in many different layers, and then it was fedexed as i said, del. >> courtney keeley for us live in washington. thank you very much. former presidential candidate, lindsey graham has endorsed former governor jeb bush for president. bush and the six rivals facing off in that debate last night, and it was clear that any
