On Wednesday, the 19th of September, the event calendar is light on important data releases. The UK will post Consumer Price Index data, Eurozone will post Current Account data and the US will present Building Permits, Housing Starts and Crude Oil Inventories data. There is a speech by ECB President Mario Draghi scheduled at 02:00 pm GMT.

GBP/USD analysis for 19/09/2018:

The UK CPI data will be the most important event of the day as the market participants expect the inflation to jump from 0.0% to 0.5% on monthly basis. On the yearly basis, the CPI is expected to slightly decrease from 2.5% to 2.4%. Moreover, the CPI Core figures are expected to decrease as well, from 1.9% to 1.8%.

The Consumer Price Index (CPI) measures the change in the price of goods and services from the perspective of the consumer. It is a key way to measure changes in purchasing trends and inflation. A higher than expected reading should be taken as positive/bullish for the GBP, while a lower than expected reading should be taken as negative/bearish for the GBP.

Let's now take a look at the GBP/USD technical picture at the H4 time frame. The market is trading just below the technical resistance zone between the levels of 1.3191 - 1.3217 in overbought conditions. The momentum is still positive, so a spike higher can occur if the data will bear the expectations (higher probability of BoE interest rate hike in the future). The nearest technical support is seen at the level of 1.3081. Please notice, the current waves are equal in the 1:1 ratio at the level of 1.3168.
