Alternative Indicators for Chinese Economic Activity Using Sparse PLS Regression

Official Chinese GDP growth rates have been remarkably smooth over the past decade, in contrast with alternative Chinese economic data. To better identify Chinese business cycles, we construct a sparse partial least squares (PLS) factor from a wide array of Chinese higher-frequency data, targeted toward variables that are highly correlated with important aspects of the Chinese economy. Our resulting alternative growth indicator clearly identifies Chinese business cycle fluctuations and it performs well both in out-of-sample testing for China as well as when applied to other economies. Using ...

Global Supply Chain Pressure Index: May 2022 Update

Supply chain disruptions continue to be a major challenge as the world economy recovers from the COVID-19 pandemic. Furthermore, recent developments related to geopolitics and the pandemic (particularly in China) could put further strains on global supply chains. In a January post, we first presented the Global Supply Chain Pressure Index (GSCPI), a parsimonious global measure designed to capture supply chain disruptions using a range of indicators. We revisited our index in March, and today we are launching the GSCPI as a standalone product, with new readings to be published each month. In ...

A New Approach for Identifying Demand and Supply Shocks in the Oil Market

An oil-price spike is often used as the textbook example of a supply shock. However, rapidly rising oil prices can also reflect a demand shock. Recognizing the difference is important for central bankers. A supply-driven increase in the price of oil can result in higher unemployment and inflation, leaving central bankers with the difficult decision to loosen policy, tighten policy, or not respond at all. A demand-driven increase reflecting global growth may support the case for tighter policy. In this post, we describe an approach for decomposing oil price changes into supply and demand ...

Putting the Current Oil Price Collapse into Historical Perspective

Since the outbreak of the COVID-19 pandemic in late January, oil prices have fallen sharply. In this post, we compare recent price declines with those seen in previous oil price collapses, focusing on the drivers of such episodes. In order to do that, we break oil price shocks down into demand and supply components, applying the methodology behind the New York Fed’s weekly Oil Price Dynamics Report.

Financial amplification of foreign exchange risk premia

Theories of systemic risk suggest that financial intermediaries? balance-sheet constraints amplify fundamental shocks. We provide supporting evidence for such theories by decomposing the U.S. dollar risk premium into components associated with macroeconomic fundamentals and a component associated with financial intermediaries? balance sheets. Relative to the benchmark model with only macroeconomic state variables, balance sheets amplify the U.S. dollar risk premium. We discuss applications to systemic risk monitoring.

An Examination of U.S. Dollar Declines

Although the dollar strengthened somewhat recently, its level relative to the currencies of the United States’ main trading partners is nonetheless 11 percent lower than it was at the start of 2009. This represents one of the more pronounced periods of dollar weakness over the past two decades and consequently has garnered considerable attention from market participants and policymakers alike. In this post, we examine the role of market uncertainty and currency risk premia in the pace and size of episodes of dollar weakness since 1991. We find that the most recent bout of U.S. dollar ...

A New Barometer of Global Supply Chain Pressures

Supply chain disruptions have become a major challenge for the global economy since the start of the COVID-19 pandemic. Factory shutdowns (particularly in Asia) and widespread lockdowns and mobility restrictions have resulted in disruptions across logistics networks, increases in shipping costs, and longer delivery times. Several measures have been used to gauge these disruptions, although those measures tend to focus on selected dimensions of global supply chains. In this post, we propose a new gauge, the Global Supply Chain Pressure Index (GSCPI), which integrates a number of commonly used ...

Parsimonious estimation with many instruments

We suggest a way to perform parsimonious instrumental variables estimation in the presence of many, and potentially weak, instruments. In contrast to standard methods, our approach yields consistent estimates when the set of instrumental variables complies with a factor structure. In this sense, our method is equivalent to instrumental variables estimation that is based on principal components. However, even if the factor structure is weak or nonexistent, our method, unlike the principal components approach, still yields consistent estimates. Indeed, simulations indicate that our approach ...

Revisiting useful approaches to data-rich macroeconomic forecasting

This paper analyzes the properties of a number of data-rich methods that are widely used in macroeconomic forecasting, in particular principal components (PC) and Bayesian regressions, as well as a lesser-known alternative, partial least squares (PLS) regression. In the latter method, linear, orthogonal combinations of a large number of predictor variables are constructed such that the covariance between a target variable and these common components is maximized. Existing studies have focused on modelling the target variable as a function of a finite set of unobserved common factors that ...

Is Higher Financial Stress Lurking around the Corner for China?

Despite China’s tighter financial policies and the Evergrande troubles, Chinese financial stress measures have been remarkably stable around average levels. Chinese financial conditions, though, are affected by global markets, making it likely that low foreign financial stress conditions are blurring the state of Chinese financial markets. In this post, we parse out the domestic component of a Chinese financial stress measure to evaluate the downside risk to future economic activity.
