A balance sheet is a statement showing what an entity owns, what it owes, and the residual claim of owners at a particular point in time.

The accounting identity
The balance sheet is built around:
$$
\text{Assets} = \text{Liabilities} + \text{Equity}
$$
This identity means every asset is financed either by debt claims or by the owners’ residual stake.
Why it matters economically
The balance sheet is central to solvency, leverage, and financial fragility. A firm, household, or bank can look healthy on an income measure but still face risk if its liabilities are too large, too short-term, or poorly matched against its assets.
Practical interpretation
Economists use balance-sheet analysis to study corporate finance, banking crises, household debt, and macro downturns driven by deleveraging. The structure of the balance sheet often matters as much as its size.
