Can the yanks deliver a pick-me-up to markets?

You can never rule it out. Stocks closing just off the lows after a none too bad NFP shows the fragility of things right now. There's always scope for the US to see the bright side of things but not if the futures are to be believed.

The S&P is showing -26 at 1849, just of the 1846 low. The Dow is off 207 at 15924

US Treasuries are down around 3bp across the board. 10's will get you 1.80%

There's next to no data of note out today so there'll be no excuses coming from that.
