Negative Nominal Interest Rates and Banking

The financial crisis of 2007-2009 taught us many lessons about monetary policy. Most importantly, we learned that when financial systems are impaired, central banks can backstop both illiquid institutions and illiquid markets. Actively lending to solvent intermediaries against a broad range of collateral, purchasing assets other than those issued by sovereigns, and expanding their balance sheets can limit disruptions to the real economy while preserving price stability.

We also learned that nominal interest rates can be negative, at least somewhat. But in reducing interest rates below zero―as has happened in Denmark, Hungary, Japan, Sweden, Switzerland and the Euro Area―policymakers face concerns about whether their actions will have the desired expansionary effect (see here). At positive interest rates, when central bankers ease, they influence the real economy in part by expanding banks’ willingness and ability to lend. Does this bank lending channel work as well when interest rates are negative?

Why should there be any sort of asymmetry at zero? Banks run a spread business: they care about the difference between the interest rate they charge on their loans and the one they pay on their deposits, not the level of rates per se. In practice, however, zero matters because banks are loathe to lower their deposit rates below zero….

Dodd-Frank, the CHOICE Act and Small Banks

Critics of the Dodd-Frank Act argue that the new regulatory regime has weakened small banks (see, for example, Peirce, Robinson, and Stratmann). This criticism is echoed in the Financial CHOICE Act—proposed by House Financial Services Chair Jeb Hensarling—that would largely scrap the current oversight of large systemic intermediaries in part to reduce the regulatory burden on “community financial institutions” (those with fewer than $10 billion in assets).

We share the goal of ensuring that regulation is cost effective for small banks that pose no threat to the financial system. However, we do not believe that the Dodd-Frank oversight regime of the largest, interconnected, complex intermediaries is a principal driver of the challenges facing most small banks.

Instead, we note that the decline of small banks has been going on for more than 30 years, decades before the Dodd-Frank Act became law in 2010...

Banks and interest rates: be careful what you wish for

Many people seem to think that – as a new BIS working paper concludes – banks benefit when monetary policy tightens and interest rates rise (especially from a low level). Do they? In some instances, perhaps, but as a general principle, surely not.

A casual glance at recent U.S. stock market behavior seems to support the idea that higher interest rates would be good for banks now. When the Federal Open Market Committee decided not to hike interest rates on September 17, the S&P500 dropped by 1.85% over two days, while the KBW index of bank stocks fell by 4.85%. A week later, when Fed Chair Yellen speaking about inflation dynamics expressed her continued expectations for a rate hike this year, the S&P500 edged lower, but the bank index rose by nearly 2%...
