Shadow Banking and the Four Pillars of Traditional Financial Intermediation

Emmanuel Farhi and Jean Tirole

Traditional banking is built on four pillars: SME lending, access to public liquidity, deposit insurance, and prudential supervision. This paper unveils the logic of the quadrilogy by putting core services to “special depositors and borrowers” at the heart of the analysis, and makes room for bank and depositor implicit and explicit guarantees. It analyzes how prudential regulation must adjust to the emergence of shadow banking. The model also rationalizes ring fencing between regulated and shadow banking and the sharing of liquidity in centralized platforms to counter syphoning and financial contagion.

Fragmentation and Strategic Market-Making

Laurence Daures Lescourret and Sophie Moinas

Information technology, infrastructure enhancement, and arbitrage strategies all contributeto link trading venues in fragmented markets. Our paper highlights a new cross-market linking channel: the interdependence of liquidity providers' inventory costs. We use a two-venue duopoly model involving strategic risk-averse market-makers. Costs to provide immediacy depend on market-makers' inventory aggregated across venues, implying that absorbing a shock in one venue simultaneously changes marginal costs in all other venues. Moreover, market-makers strategically choose which shock(s) to absorb. These two forces may lead to competitive prices and enhanced liquidity. Using Euronext proprietary data, we uncover evidence for these crossmarket inventory cost linkages.

Macroeconomic Imbalances and the Euro Zone. Alternative Views

Roberto Tamborini

Macroeconomic imbalances (MI) play a prominent role in the "consensus narrative" of the crisis of the Euro Zone (EZ). Accordingly, the package of governance reforms undertaken by the EZ countries amid the crisis includes the Macroeconomic Imbalances Procedure (MIP) to be enacted by the Commission. The whole approach has raised various critical and alternative views. These are examined distinguishing between the "domestic" and "external" dimension of MI, and the controversial issues are identified with reference to the MI relevance, their causes and connections with the crisis, and their policy implications.

Funding Constraints and Market Illiquidity in the European Treasury Bond Market

Sophie Moinas, Minh Nguyen and Giorgio Valente

Financial markets routinely experience a variety of frictions that hinder their efficient functioning by impacting price formation. These frictions are usually due to how trading is organized in a market, regulatory constraints, or trading capital. EconPol expert Sophie Moinas (TSE) and her co-authors propose an empirical investigation of the dynamic relationships between funding and market illiquidity measures in the European Treasury bond market. They find that funding illiquidity shocks affect bond market illiquidity and of a weaker, but significant, reverse feedback effect. Their analysis also shows that the responses of individual bonds' market illiquidity to funding illiquidity shocks increase with bond duration, the credit risk of the issuer, and with haircuts.

The Role of Pre-Opening Mechanisms in Fragmented Markets

Selma Boussetta, Laurance Lescourret and Sophie Moinas

Liquidity issues in financial markets arise because of two main factors: asymmetric information and cost of market participation. To alleviate these frictions, several exchanges start with a pre-opening period characterized by the accumulation of orders and the absence of trading. What is the role of Euronext’s pre-opening mechanism in the price discovery and liquidity formation of the exchange itself versus two other competing venues deprived of such a mechanism, namely BATS and Chi-X? EconPol expert Sophie Moinas (TSE) and her co-authors find evidence that tentative clearing prices set during the pre-opening period contribute to discover opening price; and that tentative clearing volume is positively correlated with liquidity across all three platforms.
