u.s. markets. there is a lot of concern about the slowing growth in china. that is having a knockoff effect on other parts of the economy. for example, if we look at commodities, more specifically the price of oil, it job to $40 a barrel for the first time since the financial crisis back in 2009. that is because many are worried down,na starts slowing then their demand for oil will also slow down. anchor: a demand for oil is another key indicator that the global economy could be heading downwards. reporter: which is why it's not just china, but there are other parts of the global economy that are looking uncertain. that also has investors a little bit spooked. is allople believe this part of the natural trajectory of u.s. stock markets, that these kinds of repricing of assets a somewhat formal at certain points of the economy.

the effect on personal pensions could be quite profound, could it? reporter: this affects everyone. anybody with any sorts of investments, pensions, anything in the economy, that has some role to play in what happens on the stock market. these kinds of big declines mean pretty big declines for portfolios for many people. mentioned this is the holiday season. could we see a bounce back when the markets reopen on monday? what is alsos is interesting, usually the holiday season is when you see quite a bit of slow down. we are seeing some of the highest trading volumes for the entire year. there's another index that some people like to talk about call the vix, the volatility index. but people like to call the fear index with regards to markets. if you look at that index, that
