Islamic Banking System
Islamic banks, or Sharia-compliant banks, operate without charging or paying interest on loans. Instead, they generate revenue by sharing risks with their clients.
How It Works
No Interest Islamic banks abstain from charging or paying interest on loans as the Holy Quran forbids riba, the Arabic term for interest.
Risk Sharing These banks earn by sharing risks with their clients. For instance, they might purchase a property and then lease it to the customer.
Profit When a loan is repaid, Islamic banks make a profit. This profit is structured in a way that avoids reliance on interest.
Why It's Important
Islamic banking aims to further the socio-economic objectives of the Islamic community. It bans usury and speculation, which are considered exploitative, and is based on the principle of equal sharing of profits, losses, and risks.
In addition to not having interest rates, Islamic finance's key principle is risk sharing among parties in all transactions. Below are some key Sharia-compliant products offered by banks; they have Arabic names, but many have equivalents in conventional Western banking.
Key Sharia-Compliant Products
Murabaha (Cost Plus Selling) This is the most common product in asset portfolios and applies solely to commodity purchases. Rather than taking out an interest loan to buy an item, the customer asks the bank to purchase it and sell it to them at a higher price on an installment basis. The bank's profit is predetermined, and the selling price cannot be increased once the contract is signed. In case of late or default payment, options include a third-party guarantee, collateral guarantees on the client's assets, or a penalty fee paid to an Islamic charity, as it cannot go to the bank's revenues.
Ijara (Leasing) Instead of giving out a loan for a customer to purchase an item like a car, the bank buys the product and leases it to the customer. The customer then acquires the item at the end of the lease term.
Mudarabah (Profit Sharing) In this investment, the bank provides 100% of the capital for a business's creation. The bank owns the business entity, and the customer provides management and labor. They share the profits according to a predetermined ratio, typically around 50/50. If the business fails, the bank bears all financial losses unless it is proven to be the customer’s fault.
Musharakah (Joint Venture) This investment involves two or more partners who contribute capital and management in exchange for a proportional share of the profits.
Takaful (Insurance) Sharia-compliant insurance companies offer products comparable to conventional insurance and operate like mutual funds. Instead of paying premiums, participants pool their money and agree to redistribute it to members in need according to pre-set contracts. The common pool of money is managed by a fund manager.
Fund Management Models
Wakala: The fund manager receives a fee, and the surplus remains the property of the participants.
Mudarabah: Adapted from banking, where profits and losses are shared between the fund manager and the participants.
Hybrid Model: A combination of Mudarabah and Wakala.
In some cases, the fund manager creates a Waqf, or a charitable fund.
Sukuk (Bonds) Sharia-compliant bonds started being issued in the 2000s and were standardized by the AAOIFI (Accounting and Auditing Organization for Islamic Financial Institutions), a Bahrain-based organization that has promoted Sharia-compliant regulation since 2003. Today, over 20 countries use this instrument, with Malaysia being the largest issuer, followed by Saudi Arabia. Issuers outside the Muslim world include the UK, Hong Kong, and Luxembourg.
Similar to conventional bonds, sukuk are highly attractive to governments for raising funds for development projects. However, their primary challenge is standardization; investors often find it more difficult to assess risk compared to regular bonds.
Additionally, Islamic finance is available in the form of investment funds.

Financial Market Regulati
Many of us know about AIG bailout by the US federal govt after 2008 market crash.
AIG (American International Group) faced a near-collapse during the 2008 financial crisis due to several factors. Here are the key reasons:
1. Credit Default Swaps (CDS): AIG sold a large number of CDS, which are essentially insurance contracts on bonds. When the housing market crashed, the mortgage-backed securities underlying these CDS defaulted, leading to massive losses.
2. Securities Lending: AIG engaged in securities lending, which also resulted in significant losses when the value of the securities dropped.
3. Poor Risk Management: AIG’s risk management practices were inadequate, and the company took on excessive risk without proper oversight.
4. Deregulation: The deregulation of the financial industry allowed AIG to engage in risky financial practices without sufficient regulatory oversight.
5. Over-reliance on Mortgage-Backed Securities: AIG heavily invested in mortgage-backed securities, which were considered safe until the housing bubble burst.
These factors combined to create a situation where AIG required a massive bailout from the U.S. government to avoid bankruptcy.
What about India where regulation on the open financial market is too loose. And a greater risk for customers, and common people.
You bring up a valid point. The rapid rise in real estate prices in India, coupled with relatively lax regulations for insurance companies, could indeed pose significant risks. The real estate market has seen substantial growth, with prices increasing by an average of 21% last year. This kind of rapid appreciation can lead to speculative bubbles, which, if they burst, could have serious repercussions for the financial sector, including insurance companies.
Moreover, while there are regulations in place, such as the Insurance Act of 1938 and the Insurance Regulatory and Development Authority Act of 1999, the effectiveness of these regulations in preventing excessive risk-taking is crucial. Ensuring robust oversight and risk management practices within the insurance sector is essential to prevent a scenario similar to what happened with AIG in 2008.
It’s definitely something for policymakers and regulators to keep an eye on.
Do you think there should be more stringent regulations for insurance companies in India?
