sao paulo. central bankers big weekend in jackson hole. matt has been in new york for us, digging into janet yellen's speech. tony is in berlin on angela merkel's pitch to voters. thean is in san paolothe impeachment hearings. alix: matt basel is joining us. fed officials do what they need to do with stanley fischer backing up janet yellen on the end of the day friday? matt: it was fascinating because if you look at the charts on friday, the investors expectations for a rate hike this year actually went down after they heard janet yellen speak. it was not until later that stanley fischer came on tv and said maybe we will raise rates this year. that caused a big reaction in the market. it will be interesting to see how sticky those expectations are as we get a ton of economic data. we have the big jobs report on friday. alix: the rhetoric seems to be if it is a blowout number, it's going to be very difficult for the fed to not increase interest rates in september. matt: that is certainly the risk when you look at the last two months. we have had these big job numbers of the last two months. now we are looking for something a little bit less around 180,000. we really only need 150,000
