The Federal Reserve’s reliance on macroprudential policy

July 5, 2014

In a recent speech Federal Reserve Chair Yellen has emphasized the economic cost of making financial risk a key consideration of monetary policy. While accommodative and non-conventional monetary policy may boost risk taking, enhanced regulation should secure financial system resilience and contain excesses. Only when macroprudential policy cannot achieve that goal should monetary policy step in. That time would not be now.

The volatility paradox

June 29, 2014

Brunnermeier and Sannikov illustrate in a formal model why fundamental risk and asset market volatility can be out of sync. They focus on endogenous market dynamics, such as “collateral amplification” (the mutual reinforcement of credit conditions and asset values). These endogenous dynamics imply that [i] low-risk environments foster systemic risk, [ii] market reactions to negative fundamental shocks are non-linear (i.e. can become catastrophic when the shock is large) and [iii] financial market risk can de-couple from fundamental risk.

Understanding capital flow deflection

June 28, 2014

A new academic paper asserts strong empirical evidence for capital flow deflection: one country’s capital inflow restrictions re-direct capital flows to other countries with similar economic characteristics. While the paper investigates from a policymaker angle, it would be relevant for international macro trading strategies.

The “net stable funding ratio”: a basic briefing

June 22, 2014

The “net stable funding ratio” is a quantitative liquidity standard for regulated banks, scheduled to go into effect in 2018. It will require stable funding sources to be equal or exceed illiquid assets. It may to some degree restrict term transformation of regulated banks and encourage migration into shadow banking. The impact of the new regulation will differ across countries and institutions.

Why governments have financial interest in higher inflation

June 21, 2014

With G7 public debt stocks at record highs, inflation has become a key fiscal concern. A new IMF paper estimates that a fall of inflation to zero would raise debt ratios by another 5-6%-points. A rise of inflation to 6% would lower debt ratios by 11-18%-points of GDP through real debt erosion. Inflation would offer additional fiscal benefits, such as higher revenues through “seigniorage” and progressive income tax tariffs.

How human stress increases financial crisis risk

June 15, 2014

John Coates gives a neuroscience view on how human “stress response” can aggravate financial crises. Rising market volatility causes a bodily response in form of a sustained elevation of the stress hormone cortisol in traders and investors. This raises risk aversion and may contribute to institutional paralysis. Central banks’ policies aimed at keeping markets calm in normal times may weaken traders’ immune system.

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 unintended consequences of leverage ratio requirements for banks

June 8, 2014

The Basel III capital regulation reforms introduced a non-risk based leverage ratio for banks. A new ECB paper shows that a leverage ratio requirement may have unintended negative consequences. It encourages banks that specialize on low-risk lending to raise their share of high-risk loans. And it could make overall bank portfolios more similar, increasing the contamination risk from negative surprises to expected default risks.

Understanding the ECB’s latest tool: TLTROs

June 7, 2014

On 5 June 2014 the European Central Bank announced Targeted Long-Term Repo Operations (TLTROs]. Their main purpose is to stimulate bank lending to non-financial corporations. The operations would offer conditional cheap funding to banks in large size and for maturities of up to four years. Private loan conditions should ease in response, particularly in the euro area periphery, but the impact on area-wide credit is uncertain. Also, TLTROs might effectively be used for government bond carry trades.

On public debt and economic growth

June 1, 2014

The view that high public debt is bad for growth, popularized by Reinhart and Rogoff, has failed to find much empirical support in academic research. A paper by Lof and Malinen presents evidence that over the past 55 years lower growth has typically preceded higher debt but higher debt has not usually preceded lower growth.
