We explain in a nontechnical fashion why dollar-neutral quant trading strategies (e.g. statistical arbitrage) suffered substantial losses (drawdowns) during the COVID-19 market sell-off. We discuss: (i) why such strategies work during “normal” times; (ii) the market regimes when they work best; and (iii) their limitations and why they “break” during extreme market events. An accompanying appendix (with a link to freely accessible source code) includes back-tests for various strategies, which put flesh on and illustrate the discussion in the main text.

We discuss the advantages of adopting government-issued digital currencies and a supranational digital iCurrency. This will get rid of paper money, a ubiquitous medium for spreading germs, as highlighted by the recent coronavirus outbreak. We set forth three policy recommendations for adapting mobile devices as new digital wallets, regulatory oversight of sovereign digital currencies, and a supranational digital iCurrency. We also argue that the USA should reevaluate its “exorbitant privilege and exorbitant duty” in light of the financial meltdown from the coronavirus outbreak.

A large number of decentralized cryptocurrencies has emerged since the inception of Bitcoin in 2009, with a total market size exceeding $170bn. Recent reports suggest that Russia will issue its government-backed cryptocurrency, CryptoRuble, in the middle of 2019. Russia’s primary goal in issuing a government cryptocurrency is to free its monetary system from the controls exerted by the Federal Reserve and their allied central banks. Government-issued cryptocurrencies will increase: Large sovereign states have the technological know-how and means to do this, but small and/or developing countries may be forced to outsource issuance of their government-backed cryptocurrencies to larger states.
