The Global Market Monitor provides information on price changes for the most commonly consumed staples and their potential impacts on the cost of a basic food basket. For more details, please refer to the 'Methodology & Data' page at this [link](https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdataviz.vam.wfp.org%2Freports%2Fglobal-coverage-global-market-monitor-mar-2024%3F_ga%3D2.216546710.1452952701.1719219215-2028703503.1710344334\&data=05%7C02%7Cseth.caldwell%40un.org%7C0263c631cc444c1fb32808dc95e733b0%7C0f9e35db544f4f60bdcc5ea416e6dc70%7C0%7C0%7C638550067449484289%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C\&sdata=%2B3wl7Pg0Cs6Z%2Fhb8%2FzE5hDdXV6dRDbhe%2BEqzzImWYMk%3D\&reserved=0). The Global Market Monitor follows a standardized methodology to calculate the impacts of price changes on the cost of a basic food basket for cross-country comparability. Global Market Monitor figures might differ from those presented in local market monitoring reports. Subnational price data from a range of markets on core food basket items are aggregated to produce a national-level cost of food basket dataset. Data is aggregated monthly, and when comparisons are able to be made with the previous month, the % price change at the national level is reported and classified. The change is classified as high if month-to-month changes is between 10 - 25% and severe if > 25%. Access the data directly on [HDX](https://data.humdata.org/dataset/global-market-monitor) and find additional datasets and context on the [WFP website](https://www.wfp.org/publications/market-monitor). ## Signals detection We generate signals if we detect month-to-month change in a location classifed as high or severe and the previous month-to-month change was at a lower classification. #### Examples: [Libya](https://us14.campaign-archive.com/?e=0c9936e61d\&u=ea3f905d50ea939780139789d\&id=2fac00caa6#LBY): high change int he cost of hte food basket detected in early 2021. [Syrian Arab Republic](https://us14.campaign-archive.com/?e=0c9936e61d\&u=ea3f905d50ea939780139789d\&id=bcb44b460e): severe change in the cost of the food basket detected in mid-2023. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.humdata.org/about/hdx-signals/datasets/market-monitoring.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
