Financial institutions, sometimes called banking institutions, are business entities that provide services as intermediaries for different types of financial monetary transactions. Broadly speaking, there are three major types of financial institutions:

Depository institutions – deposit-taking institutions that accept and manage deposits and make loans, including banks, building societies, credit unions, trust companies, and mortgage loan companies;

Contractual institutions – insurance companies and pension funds

Investment institutions – investment banks, underwriters, and other different types of financial entities managing investments.

Financial institutions can be distinguished broadly into two categories according to ownership structure:

Commercial banks
Cooperative banks

Some experts see a trend toward homogenisation of financial institutions, meaning a tendency to invest in similar areas and have similar business strategies. A consequence of this might be fewer ba

Essays in Bank Financing

This thesis examines the optimal mode of financing for banks and financial institutions. The first chapter, which is a joint work with Prof. Jean-Charles Rochet, investigates how Systemically Important Financial Institutions (SIFIs) should be financed. The main specificity of such firms is that their failure imposes negative externalities on the financial system and, more broadly, on the whole economy. Since their shareholders do not internalize these externalities, they tend to provide less capital than what would be socially optimal, generating too many failures. In jurisdictions where they receive tax exemptions, CoCo bonds are a simple means of increasing the resilience of SIFIs while providing large tax benefits to banks' shareholders. However, we show that when tax revenues are properly accounted for, these CoCo bonds are detrimental to social welfare. The second chapter provides a formal model of a bail-in plan, a pre-defined contract that results in self-recapitalization of a financial institution when it is in distress and has no access to equity financing. Bail-ins have the potential to eliminate inefficient bank liquidations and ease financing constraints in bad times. Using a theoretical model of a bail-in contract where banks face time varying financing frictions, taxation and liquidation costs, I show that banks' capital structure decisions and optimal financing and pay-out policies are largely affected by the design of the contingent capital (specifically the conversion ratio). However independent of its design, for an optimal level of debt, bail-in contracts always decrease shareholders incentives to build up liquid buffers and to recapitalize in good times but also eliminate any risk-taking incentives. The third chapter presents a model of bank optimal maturity structure when banks face systemic risk through correlated investments. Banks can privately affect the probability of success of their projects. Risky short-term debt can act as a disciplinary device if it is not rolled over when an adverse interim-date signal on the quality of banks' assets is received. The optimal maturity structure is the result of the trade-off between the disciplinary benefits of short-term debt and the costs of inefficient early liquidations. I show that bank asset commonality affects this trade-off since it reduces the costs of exerting effort through positive information synergies and increases the inefficiency of early liquidations through negative fire-sale externalities. In particular, there is a more important role for the disciplinary effects of short-term debt in high correlation, high fire-sale externalities and low information synergies environments.

Credit Supply and the Macroeconomy

Abhik Mukherjee

The policy response to the recent financial crisis has broadly focused on two themes: 1) Increasing the banking sectorsâ resilience to future financial shocks: 2) Improving credit availability to households and firms via lowering both short and long-term interest rates and thereby affecting short-term output and inflation. This dissertation studies how banks and firms have responded to these policy measures. The dissertation comprises of three chapters. The first two analyze the impact of capital regulation on bank lending for two different jurisdictions - United States and Switzerland. The third evaluates the response of U.S. non-financial firms to lower interest rates. The first chapter is joint work with Luisa Lambertini. We estimate the impact of bank capital regulation on lending spreads. We use U.S. firm-level data on syndicated loans matched with Bank Holding Company (BHC) data for the lending banks in our panel regressions. We find that higher bank capital leads to an increase in the loan pricing. Further, we investigate if stress test failure under the Supervisory Capital Assessment Program and Comprehensive Capital Analysis and Review leads to higher loan spreads, since financial institutions that failed were required to raise capital in the short run. Using a difference-in-difference framework, we find: 1) BHCs that failed the stress tests increased their loan pricing; 2) Loan pricing is higher for all banks after the commencement of the stress tests. These findings suggest that greater regulatory oversight and higher capital requirements have made syndicated loans more costly for firms. The second chapter is joint work with Luisa Lambertini, Dan Wunderli and Robert Bichsel. We use confidential loan-by-loan data of Swiss banks to study the impact of higher capital requirements on lending. Our data allows us to trace the link between bank capital and new credit granted at the bank level. Additionally bank-specific variation of capital targets allows us to analyze how deviation from the regulatory capital target impacts loan pricing and volume. We find that tighter capital regulation has small but statistically significant short-term effects on loan pricing and growth. We do not find a permanent effect of higher capital ratios on loan growth. In the third chapter, I study the behavior of U.S. non-financial corporates after the recent financial crisis. I document an increase in the real debt holdings and correspondingly the book leverage for these firms. Controlling for firm and time fixed-effects, I find a higher long-term debt to asset ratio to be associated with lower capital expenditures and growth in fixed capital post-crisis. This is also true for financially unconstrained firms, as determined by the Whited-Wu index, vis-a-vis pre-crisis. Moreover, firms with a higher share of long-term debt after the crisis appear to have a greater likelihood of repurchasing shares and larger dollar payouts to equity holders. The evidence points to the fact that any increase in long-term debt has had an impact on firms' capital structure but no positive effect on real investment.

Pricing interest rate, dividend, and equity risk

Sander Félix M Willems

This thesis studies the valuation and hedging of financial derivatives, which is fundamental for trading and risk-management operations in financial institutions. The three chapters in this thesis deal with derivatives whose payoffs are linked to interest rates, equity prices, and dividend payments. The first chapter introduces a flexible framework based on polynomial jump-diffusions (PJD) to jointly price the term structures of dividends and interest rates. Prices for dividend futures, bonds, and the dividend paying stock are given in closed form. Option prices are approximated efficiently using a moment matching technique based on the principle of maximum entropy. An extensive calibration exercise shows that a parsimonious model specification has a good fit with Euribor interest rate swaps and swaptions, Euro Stoxx 50 index dividend futures and dividend options, and Euro Stoxx 50 index options. The second chapter revisits the problem of pricing a continuously sampled arithmetic Asian option in the classical Black-Scholes setting. An identity in law links the integrated stock price to a one-dimensional polynomial diffusion, a particular instance of the PJD encountered in the first chapter. The Asian option price is approximated by a series expansion based on polynomials that are orthogonal with respect to the log-normal distribution. All terms in the series are fully explicit and no numerical integration nor any special functions are involved. The moment indeterminacy of the log-normal distribution introduces an asymptotic bias in the series, however numerical experiments show that the bias can safely be ignored in practice. The last chapter presents a non-parametric method to construct a maximally smooth discount curve from observed market prices of linear interest rate products such as swaps, forward rate agreements, or coupon bonds. The discount curve is given in closed form and only requires basic linear algebra operations. The method is illustrated with several practical examples.
