Measuring the frequency dynamics of financial connectedness and systemic risk

  title={Measuring the frequency dynamics of financial connectedness and systemic risk},
  author={Jozef Barun{\'i}k and Tomas Krehlik},
We propose a new framework for measuring connectedness among financial variables that arises due to heterogeneous frequency responses to shocks. To estimate connectedness in short-, medium-, and long-term financial cycles, we introduce a framework based on the spectral representation of variance decompositions. In an empirical application, we document the rich time-frequency dynamics of volatility connectedness in US financial institutions. Economically, periods in which connectedness is… 

Time-Varying General Dynamic Factor Models and the Measurement of Financial Connectedness

Ripple effects in financial markets associated with crashes, systemic risk and contagion are characterized by non-trivial lead-lag dynamics which is crucial for understanding how crises spread and,

Total, Asymmetric and Frequency Connectedness between Oil and Forex Markets

We analyze total, asymmetric and frequency connectedness between oil and forex markets using high-frequency, intra-day data over the period 2007 -- 2017. By employing variance decompositions and

Dynamic Networks in Large Financial and Economic Systems

The empirical application redefines the meaning of big in big data, in the context of TVP VAR models, and track dynamic connections among illiquidity ratios of all S\&P500 constituents, and studies the information content of these measures for the market return and real economy.

Exchange Rate Return and Volatility Spillover across Major Trading Partners of India

ABSTRACT We examine the connectedness among the series of four exchange rates with respect to the Indian Rupee. The results of Diebold and Yilmaz method which measures time-domain connectedness, show


This study analyzes the dynamic connectedness (i.e., spillovers and spillbacks) of financial stress across advanced and emerging economies. As proxy for financial stress, we reconstruct the financial

Measurement of Connectedness and Frequency Dynamics in Global Natural Gas Markets

We examine spillovers among the North American, European, and Asia–Pacific natural gas markets based on daily data. We use daily natural gas price indexes from 2 February 2009 to 28 February 2019 for

Asymmetric Connectedness of Fears in the U.S. Financial Sector

We study how shocks to the forward-looking expectations of investors buying call and put options transmit across the financial system. We introduce a new contagion measure, called asymmetric fear



A New Approach to Measuring Financial Contagion

This paper proposes a new approach to evaluate contagion in financial markets. Our measure of contagion captures the co-incidence of extreme return shocks across countries within a region and across

On the Network Topology of Variance Decompositions: Measuring the Connectedness of Financial Firms

We propose several connectedness measures built from pieces of variance decompositions, and we argue that they provide natural and insightful measures of connectedness among financial asset returns

Long Run Risk and the Persistence of Consumption Shocks

We propose a decomposition for time series in components classified by levels of persistence. Employing this decomposition, we provide empirical evidence that consumption growth contains predictable

The Horizon of Systematic Risk: A New Beta Representation

We show that a business-cycle consumption factor can explain the differences in risk premia across alternative portfolios, including recently-proposed anomalies portfolios. We argue that explicit

Nonstationarities in Stock Returns

The paper outlines a methodology for analyzing daily stock returns that relinquishes the assumption of global stationarity. Giving up this common working hypothesis reflects our belief that

The Spline-Garch Model for Low Frequency Volatility and its Global Macroeconomic Causes

Twenty-five years of volatility research has left the macroeconomic environment playing a minor role. This paper proposes modeling equity volatilities as a combination of macro- economic effects and

Long Run Macroeconomic Relations in the Global Economy

Abstract This paper presents tests of long run macroeconomic relations involving interest rates, equity, prices and exchange rates suggested by arbitrage in financial and goods markets. It uses the

Understanding the Evolution of World Business Cycles

Risks for the Long Run: A Potential Resolution of Asset Pricing Puzzles

We model consumption and dividend growth rates as containing (1) a small longrun predictable component, and (2) fluctuating economic uncertainty (consumption volatility). These dynamics, for which we

Low-Frequency Movements in Stock Prices: A State-Space Decomposition

Previous analyses have concluded that expectations of future excess stock returns rather than future real dividend growth or real interest rates are responsible for most of the volatility in stock
