An interest-free economy refers to a financial system where interest rates are not charged on transactions involving the borrowing or lending of money. Synonyms for an interest-free economy include a non-interest bearing economy, zero interest rate economy, and a no-interest economy. Such an economic system can be beneficial as it promotes fair and equal access to financial resources, reduces the burden of debt, and supports sustainable economic growth. Some countries such as Iran have implemented interest-free banking systems, while other countries have experimented with interest-free loans and microfinance programs. Overall, an interest-free economy can be an effective way to promote equality and financial stability in society.
