Comparative Banking Regulation and Deposit Insurance Around the World

Every banking system answers the same four questions: who regulates, what a bank may do, how a failing bank dies, and who protects the depositor. The answers differ instructively. Comparative questions are a fixture of the higher judicial and academic papers precisely because India's choices, a central bank regulator, universal banking without a wall, no resolution regime, and a paybox insurer recently made more generous, become visible as choices only when set beside the alternatives.

1. Who regulates: four architectures

Figure 1: Four ways to arrange the regulators

• Sectoral regulation assigns one agency per industry, which is India's position: the Reserve Bank for banking, separate regulators for securities, insurance and pensions, with the Financial Stability and Development Council as the coordinating table. The United States multiplies the model within banking itself, a bank there may answer to the Federal Reserve, the Comptroller of the Currency, the FDIC and a state supervisor at once, the famous dual banking system.
• Unified regulation puts the whole financial sector under one roof: Britain's Financial Services Authority (1997 to 2013) was the flagship, and Germany's BaFin, Japan's FSA and Singapore's MAS (which is also the central bank) are standing versions. The crisis discredited the flagship: a single agency, it turned out, can underweight prudential risk while minding conduct.
• Twin peaks divides by objective rather than industry: one peak for prudential soundness of all significant firms, one for conduct toward customers and markets. Australia built it first (APRA and ASIC, 1998); Britain adopted it in 2013, the Prudential Regulation Authority inside the Bank of England and the Financial Conduct Authority outside; the FSLRC's unified agency plus Reserve Bank was a cousin of this design.
• Central bank led supervision, India's and now the euro area's (the European Central Bank supervises significant banks directly under the banking union), argues from crisis synergy: the lender of last resort should know its borrowers. The standing objection is concentration of power and the conflict between monetary ease and supervisory rigour.

2. What a bank may do: the wall, the rule and the fence

Figure 2: Structural separation across a century

• The Glass-Steagall Act (1933) answered 1929 by separating commercial banking from securities business; its repeal by the Gramm-Leach-Bliley Act (1999) permitted the universal holding companies whose trading losses amplified 2008.
• America's post-crisis answer was behavioural rather than structural: the Volcker rule in the Dodd-Frank Act (2010) bans proprietary trading by deposit-taking banks and limits their fund investments, a wall inside the firm instead of between firms.
• Britain's ring fence, from the Vickers report (2011) and in force since 2019, requires large banks to place retail deposits and payments in a separately capitalised, separately governed subsidiary that the group's trading arm cannot drain.
• India never built a wall because it never had the casino: banks here are universal but their trading books are small, constrained by the investment and capital market exposure norms, and the structural questions arrive instead as the licensing policy's exclusion of industrial houses and the fences of section 6 and section 19 of the Banking Regulation Act.

3. How a bank dies abroad

• The FDIC model: the American insurer is also the resolution authority. A failing bank is closed on a Friday, its deposits and good assets sold over the weekend by purchase and assumption under a least cost test, and the branches open Monday under a new name; depositors seldom lose a day's access. The 2023 failures of Silicon Valley Bank and its peers showed both the machine's speed and its improvisations, a systemic risk exception invoked to cover even uninsured deposits.
• The European model legislated the lesson of taxpayer rescues: the Bank Recovery and Resolution Directive (2014) makes bail in mandatory before public money, requiring banks to carry a cushion of loss-absorbing liabilities; Switzerland's 2023 resolution of Credit Suisse by forced merger, with additional tier one bonds written to zero, displayed the doctrine and its controversies in one weekend.
• The FSB Key Attributes (2011) are the common standard, with total loss-absorbing capacity required of global systemic banks so that failure has a pre-funded hierarchy.
• India has the moratorium and amalgamation machinery and a withdrawn Bill where these regimes stand, the comparison being the sharpest way to state the resolution gap.

4. Protecting the depositor, compared

Figure 3: Deposit insurance across jurisdictions

• Coverage: the United States insures $250,000 per depositor per bank per ownership category (raised in 2008); Britain's Financial Services Compensation Scheme covers £120,000, raised from £85,000 on 1 December 2025; the European Union harmonises at €100,000; India's ₹5 lakh (2020) covers the overwhelming majority of accounts in full, a high share of depositors but a modest share of deposit value, which is the standard shape worldwide.
• Funding and pricing: most mature schemes are ex ante funds built from premiums; the FDIC prices by risk, so a bank's supervisory rating and capital decide its premium. India charged a flat 12 paise per ₹100 of assessable deposits until the Deposit Insurance and Credit Guarantee Corporation, with the Reserve Bank's approval, moved to risk-based premiums from 1 April 2026: a Tier 1 model for scheduled commercial banks and a Tier 2 model for regional rural and cooperative banks, with better rated banks paying up to a third less than the card rate and a further incentive for long, claim-free contribution.
• Mandate: the international vocabulary runs from paybox (pay insured depositors), through paybox plus (India: reimbursement plus support to resolution by transfer), to loss minimiser and risk minimiser (the FDIC, with examination and resolution powers). The IADI Core Principles, last revised in November 2025, set the benchmark: prompt reimbursement, adequate funding, public awareness, and a mandate matched to powers.
• Speed is where design shows: seven days is the British target and the international direction of travel, while India's 90-day interim payment under the 2021 amendment, met in the PMC class of cases, still presumes a bank parked under directions rather than one resolved over a weekend.

5. Quick Revision

1. Regulatory architecture is a choice among conflicts, not a search for the conflict-free design.
2. Structural separation returns in a new form after every crisis: wall, rule, fence.
3. Abroad, the deposit insurer is usually inside the resolution machine; in India it stands beside it.
4. Coverage limits everywhere protect most depositors fully and most deposit value only partly.
5. India's model is best described as central bank led, universal banking, paybox plus, resolution pending.

6. Frequently Asked Questions

Which model is the twin peaks design actually solving for?

The conflict inside a single regulator between the two things it must care about. Prudential regulation wants banks profitable and conservative; conduct regulation wants customers charged less and told more; one agency holding both briefs will, under pressure, favour whichever the last crisis punished. Twin peaks gives each objective an agency whose whole reputation rides on it, and accepts the cost, two supervisors on every large firm and a standing need for coordination. Britain's move in 2013 is the instructive case: the unified FSA had presided over both a prudential failure (Northern Rock, RBS) and conduct scandals, and splitting the objectives was the chosen cure. India's sectoral system faces the same tension within the Reserve Bank, regulator of banks and author of the customer-protection circulars alike, which is why the FSLRC's consumer-purpose principle keeps returning to the debate.

Did repealing Glass-Steagall cause the 2008 crisis?

The honest answer is only partly, and the question is a good test of precision. The firms at the crisis's centre, Bear Stearns and Lehman Brothers, were pure investment banks that Glass-Steagall would not have constrained, and the mortgage originations at its root happened in commercial banks and unregulated lenders the wall never touched. What repeal did do was permit the universal giants whose size made rescue compulsory, and erode the supervisory habit of separation. That is why the American response was the Volcker rule's activity ban rather than restoration of the wall, and why Britain chose a fence within the group rather than a ban on combination. For India the lesson runs the other way: having never permitted the combination, its structural questions are about who may own a bank, not what a bank may trade.

Is India's ₹5 lakh deposit insurance cover too low?

Measured by accounts, no: it fully covers the overwhelming share of deposit accounts, a coverage ratio by number that stands with the best systems. Measured by value, it covers under half of total deposits, which is also true, by design, of America's and Europe's limits, since insuring every rupee would price risk out of large depositors entirely and transfer bank discipline to nobody. The sharper Indian questions are different ones: speed, where 90 days against Britain's seven shows the gap a resolution regime would close; pricing, where the flat premium that made careful banks subsidise careless ones gave way to risk-based premiums only from April 2026; and the cooperative sector, where almost all actual payouts occur and where supervision, not insurance arithmetic, decides how often the fund is called.
