Intelligent transaction tax could help reduce systemic risk in financial networks

11.04.2016

A new study proposes a solution for mitigating the increasingly risky nature of financial markets, based on an analysis of systemic risk in financial networks.

A tax on individual transactions between financial institutions—based on the level of systemic risk that each transaction adds to the system—could essentially eliminate the risk of future collapse of the financial system, according to a new study recently published in the journal Quantitative Finance. It relies on an analysis of the networks of the banking system, using central bank data from Austria.

“When banks collapse, it costs a lot to bail them out, and that money usually comes from the public, from taxpayers” explains IIASA researcher Stefan Thurner, who coauthored the study with IIASA researcher Sebastian Poledna. The proposed tax would go into a government fund which could be used to bail out a struggling bank, for example. “You could also consider it a form of systemic risk insurance,” says Thurner.

Financial institutions are linked by multiple types of transactions, which Thurner and Poledna have modeled in a detailed network analysis. These transactions include deposits and loans between financial institutions. The study is the first to quantify the systemic risk that individual transactions add to the system.

‘’Since the international financial crisis in 2007 and 2008, policymakers have been discussing new ways to regulate the system in order to help avoid a repeat scenario.

The new study provides just that,” says Poledna. While introducing such a tax would require some work, the researchers argue that the data are there and the technical effort required for implementation is not overwhelming. Thurner has already presented the work to interested policymakers, supervisors, and central banks in the EU and Mexico.

“There’s currently a lot of discussion about a Tobin tax in the European Union, but the version they are proposing would tax every transaction at a flat rate. The tax we are proposing would not have to be large, in order to act as an incentive scheme for avoiding transactions that would be the most harmful for the system—banks would try to avoid transactions that generate that risk,” says Thurner.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
