Russian Sanctions: Questions and Answers

This post is authored jointly with our friend and colleague, Professor Richard Berner, Co-Director of the NYU Stern Volatility and Risk Institute.

Russia’s invasion of Ukraine is altering global security and economic relationships. In this post, we focus on the financial and trade sanctions imposed on Russia. These sanctions are the most powerful and costly punishments imposed on a major economy at least since the Cold War. Their speed, breadth and coordinated global support appear unprecedented.

Not surprisingly, the impact is immediately visible. The damage to the Russian economy and financial system includes, but is not limited to, a plunge of the ruble (by about 40 percent versus the dollar over the past month amid heightened volatility); runs on domestic banks; a sharp hike in the central bank’s policy rate; imposition of capital controls; shutdown of the Russian stock market; collapse in the value of Russian companies traded on foreign stock exchanges; removal of Russian equities from global indexes; and the collapse of Russia’s sovereign credit rating to junk status.

The purpose of this post is to pose and provisionally answer a series of questions raised by this new sanctions regime.…

Ensuring financial stability requires resilient institutions. That is why regulators around the world have strengthened capital and liquidity requirements for the largest financial intermediaries since financial crisis of 2007-09.

In a global financial system that runs on dollars, the most important financial market is the one for U.S. Treasury securities. Yet, despite its importance and general reliability, the Treasury market occasionally suffers from serious disruptions. The strains in the Treasury market during the first half of March 2020 became an important motivation for the Federal Reserve’s unprecedented anti-COVID policy actions beginning that month (see here, here and here).

In the remainder of this post, we describe the COVID-induced troubles in the Treasury market and highlight Duffie’s compelling proposal to consider requiring central clearing of U.S. Treasuries. We endorse Duffie’s call to study such a mandate, and view this is as an important element of a broader effort to modernize and reinforce the financial infrastructure….

Is China's devaluation a game changer?

Since 1978, China has engaged in an unprecedented and wildly successful experiment, moving gradually from a command economy to one based on markets; in small steps transforming a system where administrators controlled the goods that were produced to one where prices allocate resources. There were surely miscalculations along the way. But, even big blunders could largely be concealed. Until now!

What has changed in recent months? The day has come for China to become more closely integrated into the global financial system, and this has a number of implications. The most important is that as prices and quantities of financial assets (rather than goods) are determined in markets, bureaucrats lose a great deal of control. But, as recent events very clearly demonstrate, Chinese authorities are reluctant to let go....
