City sources predict the FTSE 100 will open down 26 points from yesterday's close of 5,786, tracking losses seen in the US overnight. After a strong start on the back of strong earnings from Home Depot, US stock markets yesterday sunk into the red by the close as concerns about the dreaded 'fiscal cliff' dampened the mood.The 'cliff' refers to a number of laws that, if unchanged, would result in over $600bn of automatic tax increases and spending cuts starting in January. President Barack Obama is set to meet with Congressional leaders this week to discuss plans to avert the automatic change in laws. It's a busy day today, announcement wise, with the UK Balance of Trade, BoE Inflation Report, Claimant Count Rate, and the Unemployment Rate all due out at 09:30.As regards the Inflation report, economists at Unicredit believe that: "While the Inflation Report will likely show an upward revision to the near-term path for inflation, we expect the report to leave the door open for more stimulus, should the growth outlook deteriorate."Barclays Research is of a similar vein, arguing that: "We expect the report to project inflation to be more persistently above target in the near term than in the August report (...) However, the MPC is likely to indicate that QE could be restarted should the predicted recovery fail to take hold." Looking abroad, on the agenda are: US Business Inventories, FOMC Interest Rate Minutes, US Manufacturing Inventories, US Retail Sales, and EU Industrial Production.
