Monetary Policy in a World of Cryptocurrencies∗
Monetary Policy in a World of Cryptocurrencies Pierpaolo Benigno University of Bern March 17, 2021 Abstract Can currency competition affect central banks’control of interest rates and prices? Yes, it can. In a two-currency world with competing cash (material or digital), the growth rate of the cryptocurrency sets an upper bound on the nominal interest rate and the attainable inflation rate, if the government cur- rency is to retain its role as medium of exchange. In any case, the government has full control of the inflation rate. With an interest-bearing digital currency, equilibria in which government currency loses medium-of-exchange property are ruled out. This benefit comes at the cost of relinquishing control over the inflation rate. I am grateful to Giorgio Primiceri for useful comments, Marco Bassetto for insightful discussion at the NBER Monetary Economics Meeting and Roger Meservey for professional editing. In recent years cryptocurrencies have attracted the attention of consumers, media and policymakers.1 Cryptocurrencies are digital currencies, not physically minted. Monetary history offers other examples of uncoined money. For centuries, since Charlemagne, an “imaginary” money existed but served only as unit of account and never as, unlike today’s cryptocurrencies, medium of exchange.2 Nor is the coexistence of multiple currencies within the borders of the same nation a recent phe- nomenon. Medieval Europe was characterized by the presence of multiple media of exchange of different metallic content.3 More recently, some nations contended with dollarization or eurization.4 However, the landscape in which digital currencies are now emerging is quite peculiar: they have appeared within nations dominated by a single fiat currency just as central banks have succeeded in controlling the value of their currencies and taming inflation. -

The number of cryptocurrencies has increased from about 2,000, with a market capitalization of over $200 billion in late 2017, to over 8,000, with a market capitalization of about $1.6 trillion. For context, the market capitalization of global equities is about $110 trillion, that of the S&P 500 stocks is $35 trillion and that of US Treasuries is $22 trillion. Reported trading volume in cryptocurrencies, as represented by the two largest cryptocurrencies by market capitalization, has increased sixfold, from an estimated $6.8 billion per day in late 2017 to $48.6 billion per day in May 2021.1 This data is based on what is called “clean data” from Coin Metrics; the total reported trading volume is significantly higher, but much of it is artificially inflated.2,3 For context, trading volume on US equity exchanges doubled over the same period. -
Complementary Currencies: Mutual Credit Currency Systems and the Challenge of Globalization
Complementary Currencies: Mutual Credit Currency Systems and the Challenge of Globalization Clare Lascelles1 Abstract Complementary currencies—currencies operating alongside the official currency—have taken many forms throughout the last century or so. While their existence has a rich history, complementary currencies are increasingly viewed as anachronistic in a world where the forces of globalization promote further integration between economies and societies. Even so, towns across the globe have recently witnessed the introduction of complementary currencies in their region, which connotes a renewed emphasis on local identity. This paper explores the rationale behind the modern-day adoption of complementary currencies in a globalized system. I. Introduction Coined money has two sides: heads and tails. ‘Heads’ represents the state authority that issued the coin, while ‘tails’ displays the value of the coin as a medium of exchange. This duality—the “product of social organization both from the top down (‘states’) and from the bottom up (‘markets’)”—reveals the coin as “both a token of authority and a commodity with a price” (Hart, 1986). Yet, even as side ‘heads’ reminds us of the central authority that underwrote the coin, currency can exist outside state control. Indeed, as globalization exerts pressure toward financial integration, complementary currencies—currencies existing alongside the official currency—have become common in small towns and regions. This paper examines the rationale behind complementary currencies, with a focus on mutual credit currency, and concludes that the modern-day adoption of complementary currencies can be attributed to the depersonalizing force of globalization. II. Literature Review Money is certainly not a topic unstudied. -
What the Return of Private Currencies Could Mean for Central Banks by Susan E
FEDERAL RESERVE BANK OF KANSAS CITY | JUNE 30, 2021 Déjà Vu All Over Again: What the Return of Private Currencies Could Mean for Central Banks By Susan E. Zubradt and Jesse Leigh Maniff Private digital currencies, or “crypto-assets,” have surged in popularity recently, but they are not new to the payments landscape and may present familiar challenges for central banks. Although they have yet to fulfill the main functions of money, crypto-assets still have the potential to affect financial stability and the implementation of monetary policy. The recent revival of private digital currencies has captured the imagination of those who envision a world where value can be transferred as seamlessly as information. Many individuals across a range of industries, from government to payments to finance, wonder whether private digital currencies may somehow sideline fiat money—the government-issued money that, coupled with reserves at central bank accounts, underpins the global financial system. In this article, we review the history of private currencies, reevaluate whether present private digital currencies satisfy the functions of money, and discuss the implications that “crypto-assets”—whether considered money or not—may have for monetary policy and financial stability. Historical Perspective Private currencies based on commodities have existed for millennia. Since around the sixth century B.C.E, commodity money has been the predominate monetary system (Velde 1998). Metal coins were a useful early means of payment to facilitate everyday transactions. Over time, paper currency, issued by a private entity and backed by a commodity such as gold, became the norm for money in circulation. -
Is Bitcoin Really Untethered?
THE JOURNAL OF FINANCE • VOL. LXXV, NO. 4 • AUGUST 2020 Is Bitcoin Really Untethered? JOHN M. GRIFFIN and AMIN SHAMS∗ ABSTRACT This paper investigates whether Tether, a digital currency pegged to the U.S. dollar, influenced Bitcoin and other cryptocurrency prices during the 2017 boom. Using al- gorithms to analyze blockchain data, we find that purchases with Tether are timed following market downturns and result in sizable increases in Bitcoin prices. The flow is attributable to one entity, clusters below round prices, induces asymmetric auto- correlations in Bitcoin, and suggests insufficient Tether reserves before month-ends. Rather than demand from cash investors, these patterns are most consistent with the supply-based hypothesis of unbacked digital money inflating cryptocurrency prices. INNOVATION, EXCESSIVE SPECULATION, AND DUBIOUS behavior are often closely linked. Periods of extreme price increases followed by implosion, commonly known as “bubbles,” are often associated with legitimate inventions, technolo- gies, or opportunities. However, they can be carried to excess. In particu- lar, financial bubbles often coincide with the belief that a rapid gain can be ∗John M.

Cryptocurrency: the Economics of Money and Selected Policy Issues
Cryptocurrency: The Economics of Money and Selected Policy Issues Updated April 9, 2020 Congressional Research Service https://crsreports.congress.gov R45427 SUMMARY R45427 Cryptocurrency: The Economics of Money and April 9, 2020 Selected Policy Issues David W. Perkins Cryptocurrencies are digital money in electronic payment systems that generally do not require Specialist in government backing or the involvement of an intermediary, such as a bank. Instead, users of the Macroeconomic Policy system validate payments using certain protocols. Since the 2008 invention of the first cryptocurrency, Bitcoin, cryptocurrencies have proliferated. In recent years, they experienced a rapid increase and subsequent decrease in value. One estimate found that, as of March 2020, there were more than 5,100 different cryptocurrencies worth about $231 billion. Given this rapid growth and volatility, cryptocurrencies have drawn the attention of the public and policymakers. A particularly notable feature of cryptocurrencies is their potential to act as an alternative form of money. Historically, money has either had intrinsic value or derived value from government decree. Using money electronically generally has involved using the private ledgers and systems of at least one trusted intermediary. Cryptocurrencies, by contrast, generally employ user agreement, a network of users, and cryptographic protocols to achieve valid transfers of value. Cryptocurrency users typically use a pseudonymous address to identify each other and a passcode or private key to make changes to a public ledger in order to transfer value between accounts. Other computers in the network validate these transfers. Through this use of blockchain technology, cryptocurrency systems protect their public ledgers of accounts against manipulation, so that users can only send cryptocurrency to which they have access, thus allowing users to make valid transfers without a centralized, trusted intermediary. -

A Solution Towards Eliminating Transaction Malleability in Bitcoin
J Inf Process Syst, Vol.14, No.4, pp.837~850, August 2018 ISSN 1976-913X (Print) https://doi.org/10.3745/JIPS.03.0101 ISSN 2092-805X (Electronic) A Solution towards Eliminating Transaction Malleability in Bitcoin Ubaidullah Rajput*, Fizza Abbas*, and Heekuck Oh** Abstract Bitcoin is a decentralized crypto-currency, which is based on the peer-to-peer network, and was introduced by Satoshi Nakamoto in 2008. Bitcoin transactions are written by using a scripting language. The hash value of a transaction’s script is used to identify the transaction over the network. In February 2014, a Bitcoin exchange company, Mt. Gox, claimed that they had lost hundreds of millions US dollars worth of Bitcoins in an attack known as transaction malleability. Although known about since 2011, this was the first known attack that resulted in a company loosing multi-millions of US dollars in Bitcoins. Our reason for writing this paper is to understand Bitcoin transaction malleability and to propose an efficient solution. Our solution is a softfork (i.e., it can be gradually implemented). Towards the end of the paper we present a detailed analysis of our scheme with respect to various transaction malleability-based attack scenarios to show that our simple solution can prevent future incidents involving transaction malleability from occurring. We compare our scheme with existing approaches and present an analysis regarding the computational cost and storage requirements of our proposed solution, which shows the feasibility of our proposed scheme. Keywords Crypto-currency, Bitcoin, Transaction Malleability 1. Introduction After its introduction in 2008 by Satoshi Nakamoto, the Bitcoin crypto-currency has gained significant popularity amongst other various crypto-currencies. -

Bitcoin and Money Laundering: Mining for an Effective Solution * DANTON BRYANS INTRODUCTION Technology forges ahead at a rapid pace, whether we like it or not. Criminals recognize this inevitability and use technological improvements to advance their craft,1 committing crimes from half a world away in real time. Meticulous criminals also use technological advancements to distance themselves from their illegal activities and profits through use of virtual banking and electronic money transfer systems, which allow criminals to buy, sell, and exchange goods without any physical interaction. Though such services use digital logs that serve to identify a sender and a receiver’s digital identities, criminals possess the means to obfuscate their digital identity by simply spoofing their Internet Protocol address or by using another individual’s account, essentially making their activities untraceable. -
A Bitcoin Governance Network: the Multi-Stakeholder Solution to the Challenges of Cryptocurrency
A BITCOIN GOVERNANCE NETWORK: The Multi-stakeholder Solution to the Challenges of Cryptocurrency Alex Tapscott Director, Institutional Equity Sales Canaccord Genuity Cryptocurrencies are products of the digital revolution and the networked age. As distributed networks with no central issuer and no central command, they are also a distinctly global phenomenon that will force national governments to not only re-evaluate a number of substantive regulatory issues but perhaps also re-think the very nature of governance itself. Cryptocurrencies are wresting control over many issues from traditional decision-makers. Multi-stakeholder governance, founded on principles of transparency and inclusiveness and legitimized by consensus, is the 21st century solution. When leaders of the old paradigm adapt and collaborate more closely with private enterprise, civil society organizations and other stakeholders in the network, then bitcoin and other cryptocurrency technologies can fulfill their potential and gain widespread adoption. © Global Solution Networks 2014 A Bitcoin Governance Network: The Multi-stakeholder Solution to the Challenges of Cryptocurrency i Table of Contents Idea in Brief 1 The Challenge for Governments 2 How Cryptocurrencies Work 4 Bitcoin Volatility and Price 5 Opportunities and Challenges 6 Opportunities 6 Challenges 11 A Bitcoin Governance Network 13 GSN Types for a Bitcoin Governance Network 16 Standards Networks 16 Policy Networks 18 Knowledge Networks 19 Watchdog Networks 20 The GSN Approach: Core Principles, Conclusions and -
