Which feature best distinguishes microeconomics from macroeconomics in analysing an Indian bank's business environment?

Microeconomics examines individual decision makers and markets, such as how a bank prices a deposit product, whereas macroeconomics examines economy-wide aggregates like national output, unemployment and the general price level. The split is about scope, not firm size or sector.
