Understanding the UK Consumer Price Index (CPI)

The CPI, released monthly by the Office for National Statistics (ONS), measures the average change in prices over time that consumers pay for a basket of goods and services. It is a critical indicator of inflation and economic health.

Trading Strategy for UK CPI

Step 1: Analyze Bank of England Priorities

The first step is to understand what data points the Bank of England is currently focused on. If the BoE is focused on inflation data, then the CPI report will have a significant amount of volatility because the BoE is in some way basing its interest rate decisions on that data release. To quickly determine the BoE’s current focus, you can use our Professional Economic Calendar, which includes a fundamental guide. This resource helps traders stay updated on the data points that matter most to the BoE, providing a strategic advantage.

Step 2: Use High-Low Expectation Forecasts

Professional traders rely on high-low forecasts to gauge market expectations accurately. Here’s a more detailed look at why these forecasts are crucial:

Understanding High-Low Forecasts

Economic forecasts are derived from surveys of credible institutions, each providing their best estimate on upcoming data points. Retail calendars typically present the median of these estimates, which can be misleading. The median forecast doesn’t reveal the full range of expectations and, therefore, doesn’t indicate how surprising an actual data release is compared to the extremes of analysts’ projections. In contrast, professional economic calendars include both high and low estimates. This additional information shows the analysts’ expectations at the extreme ends of their projections. Great trading opportunities arise when data releases fall outside these high and low estimates, creating market shocks that move prices significantly.

Step 3 - Choosing the Most Volatile Instrument to Trade

Using insights from institutional reports, traders can select the most responsive currency pairs. For example, if GBP/USD is particularly sensitive to economic data as outlined by the City Economic Surprise Index and the UK CPI shows a significant deviation, this pair could be an ideal target for trading.

Trade Execution Steps

  1. Confirm BoE Focus: Ensure the Bank of England is currently emphasizing inflation data. If inflation is a primary focus, the UK CPI report will have a higher likelihood of moving the market. Remember, if the central bank is focused on the data point, it’s because they are using that data point to make a decision on rates. This is the reason data points that are focused on cause volatility.
  2. Check Forecast Ranges: Before the data release, review the high and low forecast expectations for the event. Plan to trade only if the actual data significantly exceeds the high estimate or falls below the low estimate. This strategy ensures you act on genuinely surprising data and there will most likely be a follow-through reaction.
  3. Monitor Revisions: Check for any conflicting revisions in the data, as these can alter the initial market reaction. Make sure the primary release and any revisions align to support your trade.
  4. Enter Trade Promptly: Once you confirm the deviation, act quickly to enter your trade. Enter within the first 30 seconds. Speed is crucial, as market reactions to significant data surprises happen rapidly.
  5. Set Stop and Take Profit:
    • Stop-Loss: Place your stop-loss below the low of the initial spike candle to protect against adverse movements.
    • Take Profit: Aim for 30-100 pips for tier one events like the UK CPI report, adjusting based on market conditions and volatility. (Note: For tier two events, aim for 15-30 pips.)
