16:30 WIB: UK Gross Domestic Product (GDP) data in December 2018 and Preliminary GDP in 2018 (High impact on GBP).
GDP is considered a measure of a country's economic growth, and is usually announced per quarter. The GDP number represents a change in the percentage of the total value of goods and services produced by a country in a given period of time compared to the previous period. In the UK, sectors that contribute to changes in GDP are production, services, construction and agriculture.
UK GDP is released by Office for National Statistics (ONS) 3 times per quarter, namely Preliminary, Second Estimate, and Final. Each is released on a quarterly basis (q / q) and yearly (q / y). Starting in July 2018, the UK ONS also releases monthly GDP data in addition to GDP per quarter. High-impact ones are usually q / q and monthly data. Compared to Second Estimate and Final, Preliminary data as the initial release has the most impact. But if there is a change in the Second Release and Final, then the two data will have a high impact as well.
