Monetary policy and financial stability: What role for the futures market?

This paper examines interactions between monetary policy and financial stability. There is a general view that central banks smooth interest rate changes to enhance the stability of financial markets. But might this induce a moral hazard problem, and induce financial institutions to maintain riskier portfolios, the presence of which would further inhibit active monetary policy? Hedging activities of financial institutions, such as the use of interest rate futures and swap markets to reduce risk, should further protect markets against consequences of unforeseen interest rate changes. Thus, smoothing may be both unnecessary and undesirable. The paper shows by a theoretical argument that smoothing interest rates may lead to indeterminacy of the economy's rational expectations equilibrium. Nevertheless, our empirical analysis supports the view that the Federal Reserve smoothes interest rates and reacts to interest rate futures. We add new evidence on the importance for policy of alternative indicators of financial markets stress.     

Dynamic spillover effects in futures markets: UK and US evidence

Previous studies on spillover effects in futures markets have so far confined themselves to static analyses. In this study, we use a newly introduced spillover index to examine dynamic spillovers between spot and futures markets volatilities, volume of futures trading and open interest in the UK and the US. Based on a dataset over the period February 25, 2008 to March 14, 2013, that encompasses both the global financial crisis and the Eurozone debt crisis, we find that spot and futures volatilities in the UK (US) are net receivers (net transmitters) of shocks to volume of futures trading and open interest. The analysis also sheds light on the dynamic interdependence of spot and futures markets volatilities between the US and the UK. Specifically, the spot and futures volatility spillovers between the UK and US markets are of bidirectional nature, however, they are affected by major economic events such as the global financial and Eurozone debt crises. Several robustness checks endorse our main findings. Overall, these results have important implications for various market participants and financial sector regulators.     

The reaction of international stock markets to Federal Reserve policy

This paper investigates how changes in Federal Reserve policy impact international stock returns, with the three objectives of measuring the reaction of international stock markets, understanding the transmission channels of that reaction, and explaining the economic sources of that reaction. We find that unanticipated Federal Reserve policy actions exert a significant and robust influence on international stock prices. However, the influence of unanticipated monetary policy actions is not strong enough to change the correlation structure of international equity returns. We also find that international stock return co-movements play an important role in the transmission of monetary policy. Finally, the variance decomposition analysis indicates that the effects of monetary policy surprises on future excess returns or dividend returns account for the largest portion of the equity price response.     

Informational linkage and price discovery between China's futures and spot markets: Evidence from the US–China trade dispute

This study examines the effects of the US–China trade dispute on the informational linkages and price discovery between China's futures and spot markets. Using the daily price data of four assets representing the real and financial sectors in China during 2016–2019, empirical findings suggest that the futures–spot correlations for the stock index, copper, and corn markets have increased significantly during the trade dispute. In contrast, sharp declines in the dynamic correlations between gold futures and spot markets, as gold is a safe haven asset, are observed during the event window. During uncertainty disturbance (i.e., the trade dispute), the futures–spot cointegrated relationships in the gold and corn markets are found to adjust more quickly and efficiently, whereas the correction speeds of the market deviations for the stock index and copper market are moderately slower. With the intensive integration of market expectations with uncertainty shocks, the economic shocks of trade disputes tend to remarkably improve the pricing efficiency of China's futures markets, except for the gold futures market. China's spot markets, however, seem to be more sensitive to the noise trades and information disturbances arising from the trade dispute.     

Clearing and settlement during the crash

This article is a reexamination of the clearing and settlementprocess in financial markets (particularly the futures market)and its performance during the 1987 stock market crash. It providesboth some institutional background and some conceptual perspectiveon the problems faced by the system during the week of October19. Much of the discussion is based on the useful analogiesthat can be drawn between the clearinghouse and other financialintermediaries, such as banks and insurance companies. A majorconclusion is that the Federal Reserve played a vital role inprotecting the integrity of the clearing and settlements systemduring the crash.

Stock market margin requirements and volatility: Implications for regulation of stock index futures

This article reexamines the evidence on the relationship between stock market margin buying and volatility, and discusses the implications for the regulation of futures markets margin requirements. Post-war data provide no evidence of a link between the initial margin requirements set by the Federal Reserve and stock market volatility. Over the entire period in which the Federal Reserve has set margin requirements (1934-present), there is a correlation between margin requirements and margin debt on the one hand and volatility on the other. However, margin debt is not primarily associated with downside volatility and margin requirements are not primarily associated with upside volatility, as would be expected if margin buying were the cause of the volatility. Thus, the experience with stock market margin requirements provides no support for regulating futures markets margins in order to curb volatility. While this evidence does not rule out the possibility that margin buying contributed to the speculative boom of the 1920s and the 1929 crash, margin debt represented a much greater fraction of the 1929 stock market than have stock market futures in the 1980s. Even taking the experience of the 1920s into account, therefore, there is still no justification for regulating futures margins in order to curb volatility.This article was prepared for the Columbia Center for the Study of Futures Markets Conference on Regulatory and Structural Reform of Stock and Futures Markets.     

Realized volatility spillovers between US spot and futures during ECB news: Evidence from the European sovereign debt crisis

We study the simultaneity impact of the European Central Bank news on the daily realized volatility transmission mechanism (spillovers) among various US spot and futures markets. To this end, we apply a bias-corrected vector autoregressive model via Wild bootstrap simulation. We use minute-by-minute intraday data to construct daily realized volatility. We consider 429 news form the ECB as important events employing two major classifications, namely, a country classification with the highest total number of days related ECB news and a type of ECB news classification. We find that investors in futures markets react more vigorously and mainly for the ECB news that is associated with the group of EMU member states applied structural reforms. Yet, more importantly, we show that the US stock markets response heterogeneously to the ECB news, as we find key disagreements in the reactions both across the US markets and the types of ECB news studied. Such evidence is consistent with the explanation of the differential interpretation of information among market participants. From a practical point of view, we suggest that investors in the US spot market can effectively use two or more futures contracts to minimize their exposure to volatility risk associated with that news.     

Monetary policy and stock market dynamics across monetary regimes

This paper examines the dynamic linkages between monetary policy and the stock market during the three distinct monetary regimes of Burns, Volcker and Greenspan since the 1970s. Some major findings are the following. First, in the 1990s it appears that there was a disconnection between Federal Reserve actions (via the federal funds rate) and responses by the stock market. Second, the impact of inflation on the stock market did not surface as significant in the later parts of 1980s and the 1990s. And third, significant asymmetric effects of monetary policy on the stock markets were observed throughout each monetary regime but these were more pronounced during bear markets than bull markets. These results suggest that there was no consistent dynamic relationship between monetary policy and the stock market and that the nature of such dynamics was different in each of the three monetary regimes.     

美国第二轮量化宽松货币政策的影响及中国对策

美联储第二轮量化宽松货币政策预计对美国经济的刺激作用有限,并会对其他国家特别是新兴市场带来较严重的负面溢出效应。其中,美元泛滥可能引发较为严重的通货膨胀,并刺激贸易保护主义抬头。中国需要采取＂堵疏结合、攻防有序＂的手段,严格监控风险度高的短期流动资金,将长期资金流入有效疏导到金融短板加以利用,力保经济平稳较快发展。同时,应加强与国际社会的协作,对美国量化宽松政策形成一定的制约。     

Determinants of global spillovers from US monetary policy

This paper assesses the global spillovers from identified US monetary policy shocks in a global VAR model. US monetary policy generates sizable output spillovers to the rest of the world, which are larger than the domestic effects in the US for many economies. The magnitude of spillovers depends on the receiving country's trade and financial integration, de jure financial openness, exchange rate regime, financial market development, labour market rigidities, industry structure, and participation in global value chains. The role of these country characteristics for the spillovers often differs across advanced and non-advanced economies and also involves non-linearities. Furthermore, economies that experience larger spillovers from conventional US monetary policy also displayed larger downward revisions of their growth forecasts in spring 2013 when the Federal Reserve upset markets by discussing tapering off quantitative easing. The results of this paper suggest that policymakers could mitigate their economies' vulnerability to US monetary policy by fostering trade integration as well as domestic financial market development, increasing the flexibility of exchange rates, and reducing frictions in labour markets. Other policies – such as inhibiting financial integration, industrialisation and participation in global value chains – might mitigate spillovers from US monetary policy, but are likely to reduce long-run growth.     

An alternative approach to evaluating the agreement between financial markets

This research investigates that the price relationship between a stock index and its associated nearby futures markets can be explained by the cost-of-carry model using the concordance correlation (CC) coefficient in the US financial markets. The main purpose of this research is to confirm that the CC coefficient is an appropriate methodology to determine ex post arbitrage opportunities and to maximize ex ante arbitrage profits through the analysis of the price relationship derived from the cost-of-carry model. To increase the robustness of the results and to enable us to generalize our conclusions, this analysis is carried out in consideration of external uncertainty, including the marking-to-market procedure of futures contracts and the transaction cost on the stock index and its futures markets, under several assumptions related to the conditions of transactions. Examining transaction price data on the S&P 500 stock index and its futures markets shows that the CC coefficient gives a good result for ex ante arbitrage profits and is appropriate for analyzing the relationship between the observed stock index futures market price and its theoretical price derived from the cost-of-carry model.     

Communication by Central Bank Committee Members: Different Strategies, Same Effectiveness?

The paper assesses the communication strategies of the Federal Reserve, the Bank of England, and the European Central Bank and their effectiveness. We find that the effectiveness of communication is not independent from the decision-making process. The paper shows that the Federal Reserve has been pursuing a highly individualistic communication strategy amid a collegial approach to decision making, while the Bank of England is using a collegial communication strategy and highly individualistic decision making. The European Central Bank (ECB) has chosen a collegial approach both in its communication and in its decision making. Assessing these strategies, we find that predictability of policy decisions and the responsiveness of financial markets to communication are equally good for the Federal Reserve and the ECB. This suggests that there may not be a single best approach to designing a central bank communication strategy.     

Impact of speculation and economic uncertainty on commodity markets

We examine the interactions between commodity futures returns and five driving factors (financial speculation, exchange rate, stock market dynamics, implied volatility for the US equity market, and economic policy uncertainty). Nonlinear causality tests are implemented after controlling for cointegration and conditional heteroscedasticity in the data over the period May 1990 – April 2014. Our results show strong evidence of unidirectional linear causality from commodity returns to excess speculation for the majority of the considered commodities, in particular for agriculture commodities. This evidence casts doubt on the claim that speculation is driving food prices. We also find unidirectional linear causality from energy futures markets to exchange rates and strong evidence of nonlinear causal dependence between commodity futures returns, on the one hand, and stock market returns and implied volatility, on the other hand. Overall, the new evidence found in this paper can be utilized for policy and investment decision-making.

Identifying the effects of a lender of last resort on financial markets: Lessons from the founding of the fed

We use the founding of the Federal Reserve to identify the effects of a lender of last resort. We examine stock return and interest rate volatility during September and October, when markets were vulnerable because of financial stringency from the harvest. Stock volatility fell by 40% and interest rate volatility by more than 70% following the monetary regime change. The drop is insignificant if major panic years are omitted from the analysis, however. Because business cycle downturns occurred in the same year as financial crises, our results suggest that the existence of the Federal Reserve reduced liquidity risk.     

The effects of U.S. quantitative easing on South Africa

This paper investigates the impact of the Federal Reserve’s monetary policy on the economy of South Africa, particularly during the period of quantitative easing and thereafter from 2009 to 2018. A VAR model, including South Africa’s inflation, output, a stock market index, exchange rate, and South Africa’s policy rate is examined to determine the impact of the Federal Reserve’s actions. Our results show that the Federal Reserve’s quantitative easing programs had only slight overall effects on South Africa’s economy. However, the way monetary policy is measured appears to have important effects for studies of international monetary spillovers as the results differ depending on the type of monetary policy measure used.

Simultaneous monetary policy announcements and international stock markets response: An intraday analysis

This paper investigates the return and volatility response of major European and US equity indices to monetary policy surprises by utilizing extensive intraday data on 5-min price quotes along with a comprehensive dataset on monetary policy decisions and macroeconomic news announcements. The results indicate that the monetary policy decisions generally exert immediate and significant influence on stock index returns and volatilities in both European and the US markets. The findings also show that press conferences held by the European Central Bank (ECB) that follow monetary policy decisions on the same day have a clear impact on European index return volatilities. This implies that they convey additional important information to market participants. Overall, our analysis suggests that the use of high frequency data is critical to separate the effect of monetary policy actions from those of macroeconomic news announcements on stock index returns and volatilities.     

THE RELATION BETWEEN THE FEDERAL FUNDS CASH AND FUTURES MARKETS

The introduction of futures contracts did not alter the regularity in the cash market that results from the Federal Reserve regulation of the bank-settlement process. Although we find a positive preholiday effect in the Fed funds futures returns, we do not find evidence that Federal Reserve regulations cause that effect. Contrary to previous observations for other futures contracts, we find Fridays and preholidays have the largest net volume. We suggest this finding of high volume is consistent with hedging activity by financial institutions before market closings.
