How statistical risk models increase financial crisis risk

June 14, 2014

Regulators and financial institutions rely on statistical models to assess market risk. Alas, a new Federal Reserve paper shows that risk models are prone to creating confusion when they are needed most: in financial crises. Acceptable performance and convergence of risk models in normal times can lull the financial system into a false sense of reliability that transforms into model divergence and disarray when troubles arise.

The rise of asset management

May 11, 2014

Bank of England’s Andrew Haldane has summarized the rise and risks of asset management in a recent speech. As demographics and economic development propel the industry to ever higher assets under management, self-reinforcing correlated dynamics become a greater systemic concern. Market conventions, accounting practices, regulatory changes and structural changes in the industry all contribute to this risk.

A theory of herding and instability in bond markets

April 26, 2014

A theoretical Bank of Japan paper suggests that instability and herding in bond markets arises from low overall confidence of investors, great importance of public information (such as central bank announcements), and high value of privileged information. This analysis goes some way in explaining drastic bond market moves in the age of quantitative easing, such as the 2013 JGB market sell-off.

The structural vulnerability of local EM assets

April 4, 2014

The rapid growth in local-currency bond markets in emerging countries has transferred foreign exchange risk from local borrowers to global institutional investors and mutual funds. Gross capital inflows have soared, magnifying the dependence of flows on mutual fund holdings, particularly on volatile open-ended fixed income funds. In the wake of these changes the “beta” of local emerging market assets has risen and the tendency towards herding has increased.

How real money funds could destabilize bond markets

March 16, 2014

A paper by Feroli, Kashyap, Schoneholtz and Shin illustrates how unlevered funds can become a source of asset price momentum due to peer pressure and redemptions. Regulatory reforms that impair bank intermediation could compound negative escalatory dynamics. This raises the risk of dislocations in fixed income markets if and when extraordinary monetary accommodation is being withdrawn.

Developed market bond yields and systemic EM risk

February 9, 2014

A new BIS paper argues that the expansion of EM local-currency bond markets and foreign-currency EM corporate issuance have strengthened the link between local EM financial conditions and global bond yields. The consequences would be (i) increased dependence of emerging financial systems on developed countries’ non-conventional monetary policies, (ii) decreased effectiveness of local monetary policies, and (iii) new systemic risks.

Central banks and equity market distress

December 17, 2013

A short Bundesbank paper presents evidence that the Federal Reserve, the ECB, and the Bank of England have long used policy rates to stabilize financial markets in times of distress. This would suggest that implicit ‘central bank puts’ are not new and that central banks’ tendency to stabilize markets in the past has not prevented serious market dislocations.

A brief history of monetary policy and asset price booms

November 20, 2013

A new NBER paper reminds us of historical episodes when loose monetary policy contributed to asset price booms and busts. The paper also provides econometric evidence that low policy rates usually support asset prices. This history may not dissuade central banks from running highly accommodative policies at present, but explains the importance of accompanying macro-prudential measures.

Dealer balance sheets and market liquidity

October 17, 2013

Even in a huge market like U.S. fixed income, dealer balance sheet management these days can impair liquidity. New Federal Reserve research suggests that during the 2013 treasury sell-off dealers reduced their own positions rather than absorbing client flows and decided to limit their market making.

When long-term institutional investors turn pro-cyclical

September 12, 2013

A new IMF paper suggests that so-called “long-term institutional investors” have largely turned pro-cyclical in recent crises. This feature may be structural and reflect (a) underestimation of liquidity needs in boom times, (b) failure of traditional risk management systems to appreciate tail risk, (c) asset managers’ short-term performance targets, (d) links between short-term performance disclosures and asset outflows, and (e) regulations and conventions that encourage herding.
