It ought not be surprising that borrowing can be difficult. In good times, households usually can obtain financing to purchase a house or car. But these loans are secured with collateral that is easy to resell. Even so, some measures suggest that it is currently more difficult than under “normal” conditions to obtain mortgage finance (see the Urban Institute’s Housing Credit Availability Index on page 16).
With firms, credit has been rising significantly in recent years—across advanced and emerging economies alike (see the BIS measures through 2017 here). Yet, commercial borrowers, especially small and medium sized enterprises, complain loudly when they feel that their ability to succeed is being hampered by overly cautious lenders. And, since lenders often find it difficult to both assess a business’s prospects and to monitor effort once a loan is made, aside from periods of euphoria borrowing can be quite difficult.
As we discuss in our primers on adverse selection and moral hazard, information asymmetries make external funding—either through equity or debt—expensive. And, while the entire financial system is designed to reduce these costs, they are still quite high…. Read More
In an effort to understand the dynamics of the distribution of consumption, income and wealth, over the past decade, there has been an explosion of research. While important debates about measurement and data interpretation continue, a range of evidence points to two important conclusions. First, over the past two centuries, the global income distribution has become far more equal. But, while the gap between countries is now much smaller, in recent decades, inequality within some advanced countries, especially in the United States, has risen.
Rather than income or consumption, in this post we focus on the distribution of wealth. Wealth affects welfare in at least two key ways. First, in the presence of borrowing constraints, it provides a buffer against fluctuations of income, allowing households to smooth consumption in the face of temporary bouts of illness or unemployment. Second, it provides the basis for household spending in retirement. .
As we will see, the distribution of wealth is far less equal than that of income. Moreover, recent research shows that, following the Great Financial Crisis of 2007-2009, the U.S. wealth distribution has become decidedly more unequal. As a result, a large portion of U.S. households appears to have little scope for meeting retirement needs out of their current net worth, making federal insurance programs key to their future well-being.

Over the past 40 years, U.S. capital markets have grown much faster than banks, so that banks’ share of credit to the private nonfinancial sector has dropped from 55% to 34% (see BIS statistics here). Nevertheless, banks remain a critical part of the financial system. They operate the payments system, supply credit, and serve as agents and catalysts for a wide range of other financial transactions. As a result, their well-being remains a key concern. A resilient banking system is, above all, one that has sufficient capital to weather the loan defaults and declines in asset values that will inevitably come.
In this primer, we explain the nature of bank capital, highlighting its role as a form of self-insurance providing both a buffer against unforeseen losses and an incentive to manage risk-taking. We describe some of the challenges in measuring capital and briefly discuss a range of approaches for setting capital requirements. While we do not know the optimal level of capital that banks (or other intermediaries) should be required to hold, we suggest a practical approach for setting requirements that would promote the safety of the financial system without diminishing its efficiency....

When a financial system is hit by unforeseen, adverse events, bank capital is the first line of defense. Capital, or net worth, is the owners’ stake in the bank. Profits and losses from a bank’s activities alter its net worth, guiding investment and risk-taking. If losses wipe out its capital, the bank becomes insolvent – its assets are inadequate to cover its fixed liabilities – and typically fails... Read More
