So far this week, we had 3 key fundamental factors for the GBP/USD, which is showing some early signs of bearish continuation. Let's go over these key factors and take a look at the cable's technical conditions.1) UK Inflation: CPI y/y (Nov.): 1.0%; Forecast: 1.2%; Previous: 1.3%. Annual CPI inflation was at the lowest in 12-years according to the Office of National Statistics (ONS): (click to enlarge; source: ONS)As we can see, food and fuel prices have been sliding sharply and pulling down the inflation rate. A low inflation will keep the BoE from raising rates in 2015. The market is projecting a rate hike in the second half of the year, but some are shifting towards early 2016. US inflation data disappointed earlier, which may have kept the market from pouring in USD-strength after the FOMC statement.Jobs Data: We also had stronger than expected jobs data, with claimant count coming in at -26.9 (forecast -19.8K, previous -25.1K) and the average earnings index (3m/y) increasing 1.4% in November (forecast 1.3%, previous 1.0%). I think in the mix of data, the inflation data is most concerning. 2) FOMC: The Fed maintained its key interest rate under 0.25%. It acknowledged some rosier economic data points, thus affirming the markets belief that the committee will indeed vote to raise rates by mid-2015. This gave the USD some strength across the board. 3) UK Retail Sales beat expectations and came in at 1.6% for November, beating forecast of 0.3%, and the previous reading of 1.0%.GBP/USD Reactions: The GBP/USD was kept bearish earlier in the week after the market failed to clear the 1.5750 level on the back of good jobs data. The poor UK inflation data was a drag. Then despite poor inflation data, the USD strengthened after the FOMC risk, but this was unable to push GBP/USD into fresh lows on the year.After UK Retail Sales data, cable rebounded. However, if this rebound fails to breach 1.57, GBP/USD still remains pressured, and looks poised for bearish continuation. A break above 1.57 would put the pair back in consolidation mode, and a break above 1.5825 would likely introduce a price bottom scenario in GBP/USD. (click to enlarge)
