No Improvement in Bank Resilience After 2008 - Science

As you likely saw and heard, there was a great deal of smoke about tightening banking regulations in the United States and globally after 2008 but, as you likely suspected, they didn't do anything substantive.

Current regulations aimed at reducing risk of crisis in the financial sector will not effectively reduce that risk, according to new research from the International Institute for Applied Systems Analysis (IIASA), published in the Journal of Economic Dynamics and Control.  Introducing regulations that aim to increase the system network resilience would be more effective, the study shows.

Science Daily:  New international banking rules would not prevent another financial crisis

The hypothesis as to the problem to solve:

The Basel III framework is a new set of international banking regulations that were proposed after the financial crisis in 2007-08, with the goal of reducing the risk of a future banking crises.  The regulations, which are currently under intense discussion, would set higher requirements for bank capital and liquidity reserves and introduce capital surcharges for systemically important banks -- those that are "too big to fail."  The aim of the Basel III regulations is to reduce the risk of system-wide shocks in the financial sector.  However, the study shows that the capital surcharges would have to be much higher that currently set in order to be effective, and that would lead to a severe loss of efficiency in the financial system.

To the non-economist, it looks like the banks went for the cheapest solution without regard for its efficacy.

Their research model:

The research is based on a state-of-the-art agent-based model of a financial system and the real economy. In particular, the study focused on banks that are "too big to fail," known as globally systemically important banks (G-SIBs).

Using the model, the researchers ran a series of experiments simulating different types of regulations and their impacts on the financial system risk and resilience.

The result:

Replacing the currently proposed Basel III regulations with different regulations that aim to restructure financial networks would be much more effective in increasing resilience while avoiding the loss of efficiency in markets, according to the study.  Such methods could include smart transaction taxes based on the level of systemic risk, which the researchers proposed in a recent study, in order to reshape the topology of financial networks.

As non-economists, we can accept the judgment of these experts or walk away.  The Rockhouse inclination is to accept it since confidence the banking system is sound has not been restored and that makes the estimation of the scientists much more plausible in terms of their judgment of the current system and their suggestions on how to fix it.

The conclusion:

"The new regulation scheme Basel III claims to explicitly address systemic risk. We were surprised to find how little it really does so under realistic scenarios. The study highlights how important data-driven agent-based modeling has become as a tool to help us identify unintended consequences of regulations and propose more effective solutions," says IIASA researcher Stefan Thurner, who co-authored the study.

"The international banking system is complex and intricately connected," explains Poledna. "In order to make intelligent regulations, it's important to analyze how regulations will affect financial networks from a systemic perspective."
