A commercial bank is a for-profit regulated financial institution whose core operations include accepting public demand and time deposits, issuing mostly short-to-medium term loans to individual consumers and commercial businesses, and processing routine payment transactions. It is differentiated from central banks (which hold national currency issuance authority) and specialized investment banks that focus exclusively on capital market and securities activity.

Key moments

Medieval eraEarly money exchange precursors emerge in Mediterranean Italian port cities; the modern term "bank" derives from the Italian word for trading bench "banca", with "bankruptcy" originating from the historic practice of breaking an insolvent exchange dealer's work bench.
1694The Bank of England is founded, marking the creation of the first widely recognized modern commercial bank prototype that standardized formal fractional reserve lending practices.
1716The Bank of Scotland launches as one of the world's first fully joint-stock commercial banks, establishing an ownership structure that became the global standard for the sector.
1800 to 1870National universal commercial banks launch across continental Europe including France's Banque de France and Germany's Deutsche Bank, expanding access to large-scale credit to support rapid industrialization.
Late 20th century to 2020sGlobal commercial banks accelerate full-scale digital transformation, rolling out end-to-end mobile and online banking services that drastically reduce reliance on physical brick-and-mortar branch networks.

Unique Systemic Regulatory Status

Unlike non-financial enterprises or other types of financial service providers, commercial banks are explicitly authorized to participate in credit creation: every new valid loan they issue generates a corresponding new deposit in the broader financial system, making them the primary transmission channel for national central bank monetary policy. Regulators enforce far stricter capital adequacy, liquidity reserve, and consumer protection rules for commercial banks than for most other private industries, to avoid systemic collapse that would disrupt broad public and business access to stored funds.

Blurring Historical Industry Boundaries

For most of the 20th century, regulators in most jurisdictions strictly separated low-risk deposit-taking commercial banking activity from high-risk securities-focused investment banking operations (for example, under the U.S. Glass-Steagall Act). Decades of deregulation have erased most of these lines: nearly all large contemporary commercial banks now offer expanded adjacent services ranging from personal wealth management, credit card issuance, mortgage brokering, and corporate financial advisory support.

Pressures From Fintech Disruption

The rapid growth of non-bank fintech payment platforms and branchless challenger neo-banks has forced legacy traditional commercial banks to cut service fees, streamline digital user experiences, and shift focus to high-margin niche offerings such as small business lending and cross-border trade financing to maintain long-term profitability, a sector transition widely projected to continue through the 2030s.

A commercial bank is a financial institution that accepts deposits from the public and provides loans to its clients in order to make a profit.

It can also refer to a bank or a division of a larger bank that deals with wholesale banking to corporations or large or middle-sized businesses, to differentiate from retail banks and investment banks. Commercial banks include private sector banks and public sector banks. However, central banks function differently from commercial banks, despite a common misconception known as the "bank analogy". Unlike commercial banks, central banks are not primarily focused on generating profits and cannot become insolvent in the same way as commercial banks in a fiat currency system.[1]

History

The name bank derives from the Italian word banco 'desk/bench', used during the Italian Renaissance era by Florentine bankers, who used to carry out their transactions on a desk covered by a green tablecloth.[2]
