Stablecoin Devaluation Risk

Stablecoin Devaluation Risk

by Barry Eichengreen, My T. Nguyen, Ganesh Viswanath-Natraj

Stablecoins’ reliance on centralized custodians introduces devaluation risk similar to that of traditional currencies under fixed exchange rate regimes. The authoers construct market-based measures of stablecoin devaluation risk using spot and futures prices for Tether, estimating an average devaluation probability of 60 basis points annually and peaking at over 200 basis points during the 2022 Terra-Luna crash. Key risk factors include market volatility and transaction velocity, with elevated interest rates indicating devaluation risk. Deviations from covered interest rate parity point to segmentation between traditional and stablecoin markets, driven by leverage trading and arbitrage costs. Our findings suggest the need for increased transparency and regulatory oversight to mitigate stablecoin risk.

The Renminbi as Global or Regional Currency

The Renminbi as Global or Regional Currency

By Barry Eichengreen (UC Berkeley) & Domenico Lombardi (CIGI)

The project, undertaken jointly with Domenico Lombardi of CIGI (Canada), sought to analyze the Chinese renminbi’s prospects as a global and regional currency, the question being whether the renminbi is more likely to play a consequential international role globally or within Asia.  To this end, the following aspects of renminbi internationalization were analyzed.

a)      The weight on the renminbi as an anchor currency in the exchange rate baskets of different countries, following the methodology pioneered by Frankel and Wei.

b)      The geographic distribution of People’s Bank of China renminbi swap lines, following the methodology of Garcia-Hererro et al.

c)       The timing of announcements designating official renminbi clearing banks for different foreign financial centers.

d)      The geographic distribution of QFI and QFII foreign investor renminbi quotas.

e)      The role of the renminbi in the IMF’s SDR basket and Asia’s Chiang Mai Initiative Multilateralization.

f)       The role of political linkages and alliances in the reserve-composition decisions of central banks and governments.

The analysis did not definitively determine whether the renminbi’s future was as a global or regional currency, but it identified factors and influences on which the outcome is likely to turn.

Research papers in this stream were presented in the 2015-6 academic year to seminars and conferences at UC Berkeley (Center for Chinese Studies), Stanford University (Center for Asian Studies), Harvard University, the University of Malaysia (Jeffrey Chia Institute), and the Korea Development Institute.

Stability or Upheaval? The Currency Composition of International Reserves in the Long Run

Stability or Upheaval? The Currency Composition of International Reserves in the Long Run

by Barry Eichengreen, Livia Chitu & Arnaud Mehl

STABILITY OR UPHEAVAL?

This project analyzes how the role of different national currencies as international reserves was affected by the shift from fixed to flexible exchange rates. The authors extend data on the currency composition of foreign reserves backward and forward to investigate whether there was a shift in the determinants of the currency composition of international reserves around the breakdown of Bretton Woods. They find that inertia and policy-credibility effects in international reserve currency choice have become stronger post-Bretton Woods, while network effects appear to have weakened. They show that negative policy interventions designed to discourage international use of currency have been more effective than positive interventions to encourage its use. These findings speak to the prospects of currencies like the euro and the renminbi seeking to acquire international reserve status and others like the U.S. dollar seeking to preserve it.
