Concept:Commercial banks help economic development mainly by collecting deposits and making those funds available to borrowers for productive ventures.
Explanation:Banks receive savings from the public.
They lend these deposits to businesses, farmers, and entrepreneurs.
This process is known as financial intermediation.
It turns idle money into active investment.
Loans are used to buy machinery, raw materials, and equipment.
This raises production, creates jobs, and increases national income.
By advancing credit, banks also encourage capital formation.
Capital formation leads to improvements in agriculture, industry, and infrastructure.
Therefore, the main way commercial banks support economic development is through lending, not by performing auxiliary services like safeguarding valuables, executing wills, or advising the government.
