Fallacies, Irrelevant Facts, and Myths ll l d h in the Discussion of Capital Regulation: in the Discussion of Capital Regulation: Why Bank Equity is Not Expensive Anat R. Admati Peter M. DeMarzo Martin F. Hellwig Paul Pfleiderer Challenges to Financial Stability Policy Workshop Bank of England March 23, 2011 Balance Sheet Fallacies: Confusing Language Balance Sheet Fallacies: Confusing Language • “Banks have an incentives to minimize the capital the hold, because reducing capital frees up economic resources that can be directed to profitable investments.” (“An Explanatory Note on Basel II Risk Weight Functions,” Basel Committee, July 2005.) • “Capital is the stable money banks sit on... Think of it as an expanded rainy day fund.” (“A piece-by-piece guide to new financial overhaul law,” AP July 21, 2010). • “The B “Th British iti h B Bankers' k 'A Association i ti … calculated l l t d th thatt d demands d th thatt th they b bolster l t th their i capital will require the UK's banking industry to hold an extra £600bn of capital that might otherwise have been deployed as loans to businesses or households.” The Observer (July 11, 2010). • “Every dollar of capital is one less dollar working in the economy” (Steve p by y Floyd y Norris, “A Baby y Step p Bartlett, Financial Services Roundtable, reported Toward Rules on Bank Risk,” New York Times, Sep. 17, 2010.) • "It's just not worth it to have all that capital trapped" (A lawyer advising banks on h how tto restructure; t t “Foreign “F i Banks B k Find Fi d Loophole L h l O On US C Capital it l R Rule,” l ” Wall W ll St Streett Journal, Feb 18, 2011.) Assets: Loans to home buyers and productive enterprises Funding: Equity (capital) g q y( p ) and Debit (depositors and other creditors) What is “Capital” What is Capital and What is the Debate? and What is the Debate? • Language often confuses two sides of the balance sheet. Language often confuses two sides of the balance sheet. – “Capital” is on the right hand (liabilities and equity) side. – Capital requirements are about funding and leverage. Capital requirements are about funding and leverage – Reserve and liquidity requirements constrain the asset side of the balance sheet. the balance sheet. • “Regulatory capital” often allows securities other than equity such as trust preferred hybrid securities etc equity such as trust preferred, hybrid securities, etc. • In this discussion, focus on equity. – “HOLD” capital = fund with equity. – Hybrids and subordinated debt (“Tier 2”) are problematic. – This refers to the numerator in capital ratio. 4 The Denominator in Capital Ratio “Risk‐Weighted Assets” vs Total Assets International Monetary Fund Global Financial Stability Report, April 2008 5 Historical Facts About Bank Capital p • In 1840, equity funded over 50% of bank assets in US. • Over the subsequent century equity ratios declined consistently to single digits. • There is evidence that steps to enhance “safety net” contributed to this. In the US – National Banking Act, 1863 – Creation of the Fed, 1914 , – Creation of FDIC, 1933. • Similar trends in UK, Germany. More trading business. l d d b q y y y • Bank equity did not have limited liability everywhere in the US until 1940s!

Basel II and Basel III Capital Requirements Basel II and Basel III Capital Requirements • Tier 1 capital Ratio: Equity to risk‐weighted assets: – Basel II: 2%, Basel II: 2% – Basel III: 4.5% ‐ 7%. – Definitions changed on what can be included. • Leverage Ratio: Equity to total assets: – Basel II: NA Basel II: NA – Basel III: 3%. • Tier 2: complete to 8% (Basel II), a bit more (Basel III) Tier 2: complete to 8% (Basel II) a bit more (Basel III). • Basel II never fully implemented in the US. “Overwhelmed by the recent crisis scarcely after it has been introduced ” (Haldane, 2010) recent crisis scarcely after it has been introduced. (Haldane 2010) • Basel III: Very long implementation period (decade). • Will Basel III help prevent another crisis? Mantra: “Equity Mantra: Equity is Expensive! is Expensive!” • “More equity… would restrict [banks’] [banks ] ability to provide loans to the rest of the economy. This reduces growth and has negative effects for all.” Josef Ackermann, CEO of Deutsche Bank (Nov (Nov. 20, 20 2009). 2009) • “[D]ouble [D]ouble-digit digit [capital] ratios will undermine lending lending.” Vikram Pandit, Citi CEO, Financial Times, November 10, 2010). • “[C]apital adequacy regulation can impose an important costt because b it reduces d th the ability bilit off b banks k tto create t liquidity by accepting deposits.” Van den Heuvel (2008, p. 299). ) Leverage and Lending Spread in US (over 3‐Months Treasuries) Lending Spreads have Not Decreased with More Leverage g p g 13 Is Bank Equity “Expensive?” q y p • Yes, privately for banks, but almost entirely because of public subsidies to debt!! because of public subsidies to debt!! –Tax advantage: the more debt, the lower the tax bill. h b ll –Underpriced Underpriced guarantees guarantees • Underpriced deposit insurance. • Implicit guarantees I li it t py g • Both imply that borrowing rates do not fully reflect riskiness of assets. •B Bottom line: debt is attractive; equity is tt li d bt i tt ti it i penalized. The “Safety Net” • Motivation: stability, prevent inefficient runs. • Composition: – Deposit insurance – liquidity window – Implicit backing of government sponsored enterprises I li it b ki f t d t i – Too‐big/important/interconnected‐to fail. • C Covered 45% of US bank liabilities in 1999 (Walter and d 45% f US b k li biliti i 1999 (W lt d Weinberg, 2002), 59% of bank liabilities in 2008 (Malysheva and Walter, 2010). • Credit ratings reflect increasing size of “too‐big‐to‐fail” subsidy. • Value of the subsidies is substantial. Value of the subsidies is substantial – Ex ante: subsidized borrowing rates. – Ex post: cost of bailouts, resolution of failed institutions. Consequences of Safety Net • Many distortions, especially when guarantees are underpriced: – Incentives/ability to grow inefficiently due to subsidized funding. – Incentives to evade capital regulation regulation. – Excessive risk taking. • Does this system make sense? NO! Highly distortive and paradoxical. • Even if subsidyy is p passed to borrowers, delivering g subsidy y through g leverage is bad policy; subsidies must be questioned. – If Goldman invests in Facebook or JPM in Twitter, who is subsidized and why? y – Systemic risk = negative externality. – Excessive risk taking. • Impossible/undesirable for government to commit not to bail out. • Difficult to price guarantees, moral hazard remains a problem. • Best approach: MUCH MORE EQUITY!!! Lost Subsidies are not a Social Cost!! • Analogy: leverage = pollution; creates negative externalities. – Bank high leverage generates fragility and systemic risk risk, may lead to crisis and bailouts. • Suppose public policy subsidized polluters; the more pollution, the higher the subsidy. – The more leverage, the more banks benefit from subsidies. • Unless subsidies are made up, forcing reduction in pollution would remove subsidies and thus increase production costs. • Should pollution/leverage be allowed to keep prices low? – Taxpayers can save on subsidies and lower pollution. – Key: is there a clean and inexpensive alternative? • Is high g leverage g and fragility g y an essential part p of banking, and should it therefore be tolerated, even subsidized? Answer: NO! High bank leverage is g g an unnecessary evil! • High leverage is not inherent to banking. • High banks leverage entails a large social cost and virtually no social benefit. • While some bank debt (e.g., deposits) is part of “the business of banking” and t f “th b i f b ki ” d creates value, this does not imply high leverage. • Adding Adding equity is not equity is not socially expensive; socially expensive; actually, it is “a bargain.” Balance Sheet Fallacies Balance Sheet Fallacies • Increased Increased Capital Requirements need NOT Capital Requirements need NOT force force banks to reduce lending or deposit taking.

Higher Leverage Makes Equity More Sensitive to Asset Risk Sensitive to Asset Risk 25% Initial 10% Capital 20% Recapitalization to 20% Capital 15% 10% ROE (Earnings Yield) 5% 0% 3.0% ‐5% 3.5% 4.0% 4.5% 5.0% 5.5% 10% ‐10% ‐15% Return on Assets (before interest expenses) (before interest expenses) 6.0% 6.5% 7.0% Return on Equity for UK Banks (Haldane, 2009) ROE increases explained by increase in leverage and risk ROE increases explained by increase in leverage and risk 22 Fallacious Claim: “Equity is expensive because it h has a high required return.” hi h i d ” • Risk is priced in the market; the higher the Risk is priced in the market; the higher the risk, the higher the required return. • Less leverage lowers the required return on equity (and possibly on debt) because equity equity (and possibly on debt) because equity (and possibly debt) becomes less risky. • Redistributing risk among providers of funds does not affect overall funding costs unless it does not affect overall funding costs unless it affects the total cash available to them, which can only occur through effect on “frictions can only occur through effect on frictions.” M&M and Banking, a 50+ years Debate • Modigliani and Miller’s result does NOT imply that banks are irrelevant. • Capital structure is not irrelevant for any firm. • Denying the M&M insight is akin to denying gravity. • In a well functioning market, the cost of equity cannot be constant as leverage g changes g . • The impact p of a change g in funding g mix must be examined through its effect on frictions, i.e., how the funding mix changes the total cash available. This principle applies to banks and non-banks. Funding in the Non‐Financial World g • No capital regulation! Firms make their own decisions based on private costs and benefits decisions based on private costs and benefits. • Some considerations: – Debt has a tax advantage: firm can often pay less taxes if it pays funding providers interest instead of dividend and capital gains. – Debt increases risk of bankruptcy/default, p y , which leads to “deadweight costs” (legal expenses, interruptions, etc.). – Debt creates conflicts of interest (“agency costs”) that lead to sub‐optimal investment decisions, e.g., excessive risk‐taking, debt overhang (underinvestment). Funding in the Non‐Financial World g • Bankruptcy and agency costs of debt can increase borrowing costs increase borrowing costs. • Debt Covenants protect creditors by p y constraining what equity/managers can do. – Example: restrict dividends and more borrowing constrain investments borrowing, constrain investments. • Tradeoffs between debt and equity d determine funding mix. i f di i • On average 70% of funding for public On average 70% of funding for public firms is through equity. Funding Considerations for Banks Funding Considerations for Banks • Deposits and other “money‐like” instruments are “cheap” because they provide liquidity to creditors. • Tax code favors any form of debt. y • When liabilities are part of a subsidized safety net (underpriced guarantees), borrowing costs are low (underpriced guarantees), borrowing costs are low and do not reflect the riskiness of the assets. • Deadweight bankruptcy costs are borne by Deadweight bankruptcy costs are borne by governments. • No tradeoffs!! The ideal balance sheet is No tradeoffs!! The ideal balance sheet is “all all debt. debt ” This maximizes ROE as well. – Note: Note: “all all debt debt” is the same as is the same as “all all equity, equity ” except if except if debt is guaranteed by third party. The “Informational Insensitivity” of Debt Does NOT Necessitate High Leverage h • The The more highly leveraged the bank, the less more highly leveraged the bank the less “informationally sensitive” debt is. • As leverage increases, or in distress, information y g insensitivity no longer holds, runs can occur. • The growth of the shadow banking system does not prove that all the manufactured debt was not prove that all the manufactured debt was socially valuable. • Banks can continue providing liquidity, indeed qu d ty be e a ced, t ey add equ ty liquidity will be enhanced, if they add equity. • Additional equity need not crowd out deposits.

Governance problems can be solved without relying on leverage and fragility. Does Debt Provide “Market Does Debt Provide Market Discipline? Discipline?” “Debt is valuable in a bank’s capital structure because it provides an important disciplining force for management.” id i t t di i li i f f t” (Squam Lake, 2009) • Assessment: Myth; inadequate models with no support. Assessment: Myth; inadequate models with no support – Creditors protected by safety net do not invest in monitoring, do not bother with covenants, etc. Threat of default not credible. not bother with covenants, etc. Threat of default not credible. – High leverage of any form, even subordinated debt, exacerbates incentives for excessive risk taking. – Equity has stronger incentives than debt to monitor against waste of assets or poor effort. – No empirical evidence. Last decade contradicts these claims. N i i l id L td d t di t th l i Crisis shows this does not work, has not worked! • Even Even if… mechanism relies on fragility, very costly; is debt if mechanism relies on fragility very costly; is debt unique or best way to discipline or are there alternatives? Does Debt Control “Free Does Debt Control Free Cash Flow Cash Flow”?? • Jensen 1986 suggests debt prevents waste of cash flows by managers flows by managers. – Does high leverage uniquely solve this problem? – Can consider other ways to provide governance. – Admati & Pfleiderer 2010: Equity Liability Carrier q y y Increased Equity L.

Where was the discipline prior to 2008? 32 Does Observe High Leverage of Banks Imply High Leverage is “Optimal?” • Certainly not socially! Given incentives from taxes and implicit guarantees, privately optimal leverage is excessive from social perspective. • Except Except for subsidies, high leverage may not even be for subsidies high leverage may not even be privately optimal for banks, if viewed ex ante (assuming it was possible to make commitments to (assuming it was possible to make commitments to future investment and financing decisions). – However, once highly leveraged, banks have strong h hl l d b k h incentives to remain highly leveraged and try to “dilute” existing creditors; this leads to distorted investment existing creditors; this leads to distorted investment decisions and ex ante loss of value. Under Pricing & Issuance Costs Under‐Pricing & Issuance Costs • Debt is less subject to under-pricing (Myers-Majluf (1984) – True, but this does NOT imply high leverage is optimal – Lower leverage • Greater ability to rely on retained earnings • Equity is less sensitive so any underpricing is less severe • Easily mitigated – Restrict payouts (dividends and share repurchases) – Rights offerings: low cost & removes underpricing concern – Remove discretion: mitigate negative inferences (force issuance if capital falls too low or risk increases) 34 More Equity Has Positive Side Benefits • High leverage generates many distortions in l di /i lending/investment decisions by bank managers, working t td i i b b k ki on behalf of shareholders. – Excessive risk taking: heads we win, tails debt holders or government loses. – Debt overhang: good opportunities are passed up because new funding would benefit existing creditors. • Key factor in credit freezes in crisis. • A reason highly leveraged banks might respond to higher equity requirement by shrinking. it i t b h i ki • A problem that is alleviated with better capitalization. • Lower leverage has benefits beyond reducing systemic risk!

Equity vs. Contingent Capital or “Bail‐In” Mechanisms “ l ” h • Contingent capital and bail‐in proposals attempt to g p p p p transform debt into equity “just when needed.” • Complicated to design and value! Complicated to design and value! – What is the trigger? Who pulls it? Will it work as intended? – Manipulation issues; political pressures around trigger event, destabilizing approaching a crisis. • Is contingent capital “cheaper” than equity? – – – – No!!! False comparison to debt, dominated by equity. p y q y No (social) value to the debt‐like feature of security. Seems motivated by tax and maintaining high “ROE Seems motivated by tax and maintaining high ROE.” Equity is simplest and best cushion. No need for contortions.

Extra Cushion Debt‐like More Contingent g Equity Capital Old Capital R Requirement i Equity Capital WHY NOT simply increasing Equity instead? Capital Requirements and Lending p q g • Claims often made that increased capital requirements would lead to a credit crunch requirements would lead to a credit crunch. • Remember: biggest credit crunch (freezing of markets in the crisis) was due to excessive g p the problem. p leverage! “Too much capital” was not • Compare a bank with 5% equity to a bank with 25% equity The latter better capitalized bank 25% equity. The latter, better capitalized bank makes better lending decisions. – It is less likely to pass up profitable loans because of difficulty funding them (due to “debt overhang”). – It is less likely to over‐invest in excessively risky loans. Might There be Lending Contraction if Capital Requirements are Raised? l d • Not Not clear. (Compare option expensing debate.) clear (Compare option expensing debate ) • Possible reasons for contractions: – Problematic risk weighing system. – If funding costs increase due to lost subsidies, some g , loans might no longer be profitable at margin. – Existing leverage levels may be excessive and Existing leverage levels may be excessive and hamper capital raising because of “debt overhang.” – Equity issuance or dividend withholding carry negative “stigma” when managers are strategic and possibly base decisions on private information. What about the Unregulated Shadows? What about the Unregulated Shadows? • Many Many of the shadow banking entities are sponsored of the shadow banking entities are sponsored by regulated banks, who provide guarantees. – Hedge funds are less highly leveraged. Hedge funds are less highly leveraged • Much of the “financial innovation” in recent decade was motivated by “regulatory arbitrage,” to avoid capital requirements (and deposit insurance fees). p q ( p ) • Regulators could have intervened and should do so i h f in the future. • Determining Determining the set of regulated activities/entities the set of regulated activities/entities on a continual basis will always be a challenge. What about Competitiveness (“Level Playing Field”)? • Implicit identification of national interests with the competitive successes of the country’ss financial competitive successes of the country financial institutions is unwarranted if taxpayers are providing y the safety net. – The Irish taxpayer would have been better off if Irish financial institutions were less successful in the markets for funds and for providing loans for Irish real estate developments. – The German taxpayer would have been better off if the shadow banks of the German Landesbanken had been less successful in acquiring ABS and issuing ABCP successful in acquiring ABS and issuing ABCP. – The Swiss taxpayer would have been better off if UBS Investment Bank had been less successful in re‐securitizing Investment Bank had been less successful in re securitizing low‐grade subprime mortgage backed securities. Summary and Policy Recommendations • Require significantly more equity financing for anyone involved in credit generation. • Ratios significantly higher than 10% of un Ratios significantly higher than 10% of un‐ weighted assets should be seriously considered. – Benchmark: REIT fund with 30% equity. B h k REIT f d ith 30% it • Requirements should not be one “number,” or they cannot work as a cushion. – Concept of buffers set up in Basel III is sensible; Concept of buffers set up in Basel III is sensible; • Risk weights are very problematic. Work on alternatives. l i Policy Recommendations continued Policy Recommendations, continued • Regulators Regulators should control equity payouts and should control equity payouts and issuance. • Immediate recommendation for quick and efficient transition: ban equity payouts such as efficient transition: ban equity payouts such as dividends for all banks until banks are better capitalized; possibly mandate equity issuance. it li d ibl d t it i – This would eliminate negative inference on a given This would eliminate negative inference on a given bank that might be otherwise associated with these actions (Recall TARP initiation in U S that gave banks actions. (Recall TARP initiation in U.S that gave banks little choice but to accept the funds.) Final Observations • Public policy should not encourage bank leverage. • Subsidies are highly distortive. – Tax code is straightforward conceptually. – Guarantees are very tricky to remove (or price). Guarantees are very tricky to remove (or price) – Higher equity requirements are the best approach to i increasing stability, removing distortions such as i t bilit i di t ti h excessive risk, and reducing subsidies. • International harmonization – Very important for resolution mechanisms.
