We analyze a two-country economy with complete markets, featuring two national currencies as well as a global (crypto)currency. If the global currency is used in both countries, the national nominal interest rates must be equal and the exchange rate between the national currencies is a risk-adjusted martingale. Deviation from interest rate equality implies the risk of approaching the zero lower bound or the abandonment of the national currency. We call this result Crypto-Enforced Monetary Policy Synchronization (CEMPS). If the global currency is backed by interest-bearing assets, additional and tight restrictions on monetary policy arise. Thus, the classic Impossible Trinity becomes even less reconcilable.
Abstract Bitcoin is a distributed system. The dilemma it poses to the legal systems is that it is hardly possible to regulate a distributed network in a centralized fashion, as decentralized cryptocurrencies are antithetical to the existing centralized structure of monetary and financial regulation. This article proposes a more nuanced policy recommendation for regulatory intervention in the cryptocurrency ecosystem, which relies on a decentralized regulatory architecture built upon the existing regulatory infrastructure and makes use of the existing and emerging middlemen. It argues that instead of regulating the technology or the cryptocurrencies at the code or protocol layer, the regulation should target their use-cases. Such a regulatory strategy can be implemented through directing the edicts of regulation towards the middlemen and can be enforced by the existing financial market participants and traditional gatekeepers such as banks, payment service providers and exchanges, as well as large and centralized node operators and miners.
Son yılların önemli araştırma konusu olan kripto paralar içinde en önemlisi olan Bitcoin bir yıl içinde yirmi katın üzerinde değer kazandı ve yatırımcılar açısından güven duyulan bir para birimi haline geldi. Artan güven ile birlikte Bitcoin yatırımcılarının da çoğalmasıyla piyasadaki hacimde gözle görülür bir büyüme meydana geldi. Bu sayede Euro ve Amerikan Doları gibi para birimlerinin 2008 krizinden sonraki güvensiz hale gelmesi Bitcoin’in güven duyulan bir para birimi haline gelmesine sebep oldu. Sadece para birimleri değil menkul kıymet ve emtia gibi yatırım araçlarına da alternatif olan Bitcoin yüzyıllardır bireysel yatırımcıların vazgeçilmez yatırım aracı olan altının konumunu neredeyse alır vaziyete geldi. Söz konusu çalışma ani şekilde yükselişe geçen ve yatırımcılar tarafından hızlı bir şekilde yatırım aracı olarak kabul edilen Bitcoini, asırlardır önemli bir yatırım aracı olarak kabul edilen altına karşı ADF Birim Kök Testleri, Johansen Koentegrasyon Testi, Hata Düzeltme Modeli ve Düzeltilmiş En Küçük Kareler Modeli kullanılarak değerlendirilmektir.
This is the first paper that estimates the price determinants of BitCoin in a Generalised Autoregressive Conditional Heteroscedasticity framework using high frequency data. Derived from a theoretical model, we estimate BitCoin transaction demand and speculative demand equations in a GARCH framework using hourly data for the period 2013-2018. In line with the theoretical model, our empirical results confirm that both the BitCoin transaction demand and speculative demand have a statistically significant impact on the BitCoin price formation. The BitCoin price responds negatively to the BitCoin velocity, whereas positive shocks to the BitCoin stock, interest rate and the size of the BitCoin economy exercise an upward pressure on the BitCoin price.

Başta Bitcoin olmak üzere kripto paralar son dönemde çok sık kullanılmaya başlamıştır. “Para birimi” olarak ve “Değer birikim aracı” olarak kabul görmeye başlayan kripto paraların fiyat hareketlerinin analiz edilmesi ihtiyacı ortaya çıkmıştır. Bu piyasaların büyümesi ve küresel entegrasyonu ile birlikte fiyatlarda meydana gelen önemli değişimlerin temelinde spekülatif balonların olup olmadığı finansal istikrar konusunda açıklık ve güvence açısından önem arz etmektedir. Ayrıca kripto para piyasasında meydana gelen spekülatif hareketler piyasa katılımcılarının sürü psikolojisiyle hareket edip etmedikleri sorusunu ortaya çıkarmaktadır. Bu nedenle çalışmada Bitcoin ve Etherium para birimlerinde spekülatif balonların varlığı Philips vd. (2015) tarafından geliştirilen yöntem ile tespit edilmiş ve ne zaman oluştukları tahminlenmiştir. Piyasada balonların olması ve bu balonların süre olarak varlığı sürü psikolojisinin olduğu yönünde bilgi sağlarken, bu piyasada dengeleyici bir spekülasyonun olmadığı yönünde de bir bilgidir. Elde edilen bulgular doğrultusunda Bitcoin ve Etherium kripto para birimlerinde çok sayıda baloncuk olduğu tespit edilmiştir. Özellikle 2017-2018 yılları arasında büyük baloncukların ortaya çıkması bu para birimlerinin spekülatif hareketlere karşı eğilimli olduğunu gösterilmiştir.
Can securities be settled on a blockchain, and, if so, what are the gains relative to existing settlement systems? The main benefit of a blockchain is faster and more flexible settlement, whereas settlement fails need to be ruled out where participants fork the chain to cancel trading losses. With a proof-of-work protocol, the blockchain needs to restrict settlement speed through block size and time in order to generate transaction fees, which finance costly mining. Despite mining being a deadweight cost, our estimates for the U.S. corporate debt market yield net gains from a blockchain in the range of 1–4 bps.

This essay examines in detail the properties of a well functioning monetary system - defined as money plus the mechanisms to execute payments - in both the short and long run, drawing on both theory and the lessons from history. It stresses the importance of trust and of the institutions needed to secure it. Ensuring price and financial stability is critical to nurturing and maintaining that trust. In the process, the essay addresses several related questions, such as the relationship between money and debt, the viability of cryptocurrencies as money, money neutrality, and the nexus between monetary and financial stability. While the present monetary system, with central banks and a prudential apparatus at its core, can and must be improved, it still provides the best basis to build on.
This paper explores whether and how technological innovation, in conjunction with policy measures, can improve the process of correspondent banking cross-border payments. The paper builds on the empirical validation of existing shortcomings in this area of business by using a questionnaire and industry expert focus group sessions. Having identified the key areas of concern (e.g. cost, transparency, speed), several new network models for cross-border payments are assessed, in terms of their ability to address existing problems. Among the possible models, we also explore the use of innovative technologies such as distributed ledger technology (DLT). As a final step, we evaluate the different models and complement our findings with policy recommendations, in particular with a view to further streamlining Anti-Money-Laundering (AML) and Counter-Terrorist-Financing (CTF) as well as conduct of business rules in payments and supporting information sharing on suspicious transactions between institutions globally.
The existing credit systems are not well recognized because of separate brokerage systems, non-pertinence, centralized and static evaluation models, and insufficient supporting information. An autonomous credit system is proposed to reform and address the issues of the current systems based on self-regulating blockchain data and programmable smart contracts. The autonomous credit system is trading-oriented to satisfy all the involved trading participants. A blockchain creditworthiness ecosystem is developed to implement the credit system as it provides an open, equal and creditworthy infrastructure. And it is through a collection of smart contracts that all the blockchain operations are processes. A creditworthiness model is developed to implement the credit system to be integrated, traceable, dynamic and personalized. Several pilot projects have been developed to test the feasibility and efficiency of the proposed autonomous credit system. Four creditworthiness clouds have been developed as public blockchain clients and creditworthiness lookup services.
This paper explains how Blockchain technology and cryptocurrency could be enhancing the financial reporting process, and therefore improve corporate governance model of transparency and monitoring. The technology and forces behind the adoption of Blockchain are discussed as they relate to accounting, auditing and corporate governance. To demonstrate such applications examples from revenue recognition are used to illustrate how Blockchain can improve financial reporting, and transparency and monitoring aspects of the corporate governance.
Abstract We introduce the distributed ledger (blockchain) technology of crypto‐currencies. We examine the ‘monetary’ attributes of crypto‐currencies, and describe some of the reasons they have been adopted. The paper discusses the mechanics of Bitcoin – the original crypto‐currency – to illustrate the fundamental elements of decentralized crypto‐currencies. We then provide a high‐level summary of the implications of crypto‐currencies for consumers, financial systems, and for monetary and regulatory authorities. We argue that crypto‐currencies are unlikely to supplant traditional fiat currencies and we anticipate an enduring role for financial intermediaries in facilitating credit.
Derivatives are the “bad boys” of modern finance: exciting, dangerous, and fundamentally misunderstood. These misunderstandings stem from the failure of scholars and policymakers to fully appreciate the unique legal and economic structure of derivative contracts, along with the important differences between these contracts and conventional equity and debt securities. This Article seeks to correct these misunderstandings by splitting derivative contracts open, identifying their constituent elements, and observing how these elements interact with one another. These elements include some of the world’s most sophisticated state-contingent contracting, the allocation of property and decision-making rights, and relational mechanisms such as reputation and the expectation of future dealings. The resulting hybridity essentially splits every derivative into two separate contracts: one that governs under normal market conditions, and another that governs under conditions of fundamental uncertainty. In good times, derivative contracts contemplate the almost automatic determination and performance of each counterparty’s obligations. In bad times, these contracts include various mechanisms designed to provide counterparties with the flexibility to incorporate new information, fill contractual gaps, and promote efficient renegotiation.\nThe process of splitting derivative contracts open yields a number of important policy insights. First, the bundling of contract, property, decision-making rights, and relational mechanisms makes derivatives look far more like commercial loans than publicly traded shares or bonds. The regulatory treatment of derivatives as “securities”—and the resulting emphasis on market transparency—is thus somewhat misguided and serves to distract attention from the significant prudential risks posed by the widespread use of derivatives. Second, the flexibility associated with the relational mechanisms embedded within many derivative contracts can play a useful role in promoting both institutional and broader financial stability. This has important implications in terms of the desirability of the recent push toward mandatory central clearing of derivative contracts. It also exposes the potential perils of recent proposals to use distributed ledger technology and smart contracts to execute, clear, and settle these contracts. By the same token, the widespread breakdown of these relational mechanisms can be a source of financial instability. This provides a compelling rationale for authorizing central banks to act as “dealers of last resort” during periods of fundamental uncertainty.
Today's banking system has seen revolutionary change within a decode or more. The foremost reason being the adaptation of information technology in the banking system. Although , this has strengthened the economy of our country, it has also led to many frauds and scams in the recent times. In this research paper, we have tried to collect information on the above events and tried to preview the actual positioning of India's banking system. There has also been some discussion on the understanding, growth, usability and adaptability of crypto currencies such as Bitcoins, Ethereum, Litecoin, Dash etc. The overall discussion helps us to understand how the inner complexities of Indian banking system is leading to consumer's thoughts and interest shifting towards crypto currency. Some suggestions have also been provided as different steps which can be taken in the present situation.
Abstract In this study, we apply the Bitcoin to estimate the price of the Venezuelan bolivar, due to the unreliability of this currency's official exchange rate. Our approach is based on the triangular no‐arbitrage condition and takes the Bitcoin as an intermediate currency. To verify its validity, in addition to bolivars, six currencies are first considered in the empirical study. We find that trading through the Bitcoin market produces higher transaction costs or requires higher risk compensation than trading through the conventional exchange market. Then, we explore the Venezuelan case. Comparing the estimates of the black market bolivars, which are generated from several popular media sources and the Web site Dolartoday.com, using Bitcoin can produce reliable bolivar exchange rates quickly and easily. To sum up, we verify the feasibility of using the triangular no‐arbitrage condition in foreign exchange markets to estimate exchange rates through the Bitcoin. This is especially useful when capital controls exist such as they do in Venezuela.

This paper contributes to the literature on cryptocurrencies by examining the performance of naïve (1/N) and optimal (Markowitz) diversification in a portfolio of four popular cryptocurrencies. We employ weekly data with weekly rebalancing and show there is very little to select between naïve diversification and optimal diversification. Our results hold for different levels of risk-aversion and an alternative estimation window.
Objectives Smart e-Forms are a new form of technology that converts complex paperwork to digital forms in an enterprise setting. In the context of the rapidly changing communication channels brought by the move toward a digital innovation environment in the financial industry, this paper examines a smart e-Form solution that can aid effective business communication. Methods Financial services using smart e-Forms are developing multilaterally with the use of electronic documents in both face-to-face and non-face-to-face channels. The electronic document system for enhancing competitiveness in face-to-face environments includes PPR (paperless and process reconstruction) and tablet banking systems, while the distance contract system through mobile banking can be utilized in non-face-to-face environments. Results As a functional document format that includes business logic, smart e-Forms allow various types of data input such as photos, voice recordings, barcode scanning, and e-Signatures through the use of smart devices. This technology has been utilized in implementing paperless services, tablet banking, and distance contract systems for a number of financial institutions, and e-Form technology is being optimized for the latest mobile devices in response to the demands of the financial market. Conclusions The rapid development of smart e-Form technology has played a major role in innovation in the financial sector. This technology improves customer convenience and work efficiency for a diversified financial environment, and the e-Form-based financial service system is becoming more competitive in various ways to lead the Fourth Industrial Revolution.
We study the evolution of ideas related to creation of asset-backed currencies over the last 200 years and argue that recent developments related to distributed ledger technologies and blockchains give asset-backed currencies a new lease of life. We propose a practical mechanism combining novel technological breakthroughs with well-established hedging techniques for building an asset-backed transactional oriented cryptocurrency, which we call the digital trade coin (DTC). We show that in its mature state, the DTC can serve as a much-needed counterpoint to fiat reserve currencies of today.
