PMI as a leading indicator of economic growth
The podcast discusses the limitations of using GDP as a measure of economic growth due to its lagging nature in providing real-time insights. It highlights the importance of the Purchasing Manager's Index (PMI) as a leading indicator that offers a more immediate snapshot of the economy. By surveying senior executives on various business aspects like new orders, employment, and costs, the PMI provides a quicker assessment of the economic trajectory. The high PMI reading of 61.3 in India indicates a fast expansion in factory orders and production, signaling positive growth momentum.

It emphasizes the significance of a reading above 50 indicating growth. Additionally, it warns about the limitations of relying solely on flash PMI data, citing a case in the UK where a premature rate policy decision was made based on misleading flash PMI information. The episode underscores the necessity of waiting for final PMI numbers before major policy decisions, showcasing the importance of accurate data for economic evaluations.
