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.
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.
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.
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.

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.
Cryptocurrency, a new technology depended electronic currency, is seemed as business commodity for investment and medium of exchange to few number of people of the world. It has different forms in different countries even more different forms in the same country. Bit coin, the first and most popular cryptocurrency, is paving the way as a disruptive technology to long standing and unchanged financial payment systems that have been in place for many decades. In some countries, cryptocurrency has been recognized by the respective governments. While cryptocurrencies are not likely to replace traditional fiat currency, they could change the way internet connected global markets interact with each other, clearing away barriers surrounding normative nationa currencies and exchange rates. Cryptocurrencies bear both some advantages and disadvantages in uses. Over the last few years, it has been gaining rapid popularity in the public eye. In India, recognition process has been started to come into mainstream o the public domain. In this article, a short analysis of cryptocurrency is presented, which illuminates some of the recent events and movements that could influence whether cryptocurrency contributes to a shift in economic paradigms. The article covers th original idea and motivation, the mode of operation and possible applications of Cryptocurrencies block chain technology. We conclude the article mentioning the prospect of cryptocurrency well as in the world.

The UK Government is under growing pressure to improve the performance of public services whilst reducing costs. Services are under stress at a national and local level. This pressure to improve the value being delivered to citizens whilst reducing operational costs and risks is analogous to the pressure the financial service industry has been under since 2008. Financial services organisations are increasingly turning to Distributed Ledger Technology (DLT) to address these challenges. Distributed ledger technology is enabling a new paradigm in financial services where organisations collaborate and integrate at the infrastructure and transaction level, freeing up resources for innovation and competition at the application and value proposition level; what we are seeing is wholesale business model transformation. This paper explores how a new Public Value Network might enable Public Service Organisations to: 1. Retain their existing decentralised business models, (budgets, decision making, business, service design) yet optimise and synchronise locally and nationally 2. Collaborate in the design and delivery of frictionless human centric services 3. Automate- services, adherence to and auditing of regulation, policy and process 4. Improve financial transparency across public service value chain.

This Policy Contribution tries to answer two main questions: can cryptocurrencies acquire the role of money? And what are the implications for central banks and monetary policy? Money is a social institution that serves as a unit of account, a medium of exchange and a store of value. With the emergence of decentralised ledger technology (DLT), cryptocurrencies represent a new form of money: privately issued, digital and enabling peer-to-peer transactions. Historically, currencies fulfil their main functions successfully when their value is stable and their user network sufficiently large. So far, cryptocurrencies are arguably falling short against these criteria. They resemble speculative assets rather than money. Primarily this is because of their inherent volatility, which is the by-product of their inelastic supply, and which limits their widespread use as a medium of exchange. Cryptocurrency protocols could theoretically evolve to limit their volatility and correct their current deficiencies. If successful, this could lead to an increase in their popularity as an alternative to official currencies. A successful alternative to official currencies could put pressure on those who manage official currencies to provide better policies. But the widespread substitution of central bank currency for cryptocurrencies would effectively create parallel currencies. This by itself could create risks to the effectiveness of monetary policy, to financial stability and ultimately to growth. Nevertheless, the risks of cryptocurrencies becoming serious contenders remain small as long as fiat currencies issued by the world's major central banks continue to deliver effectively the three traditional functions of money. It would take a deep crisis of trust in official currencies for their widespread substitution by cryptocurrencies to materialise. For cryptocurrencies to replace official currencies they would have to overcome a triple challenge. First, the supply of cryptocurrency would need to act as an instrument (or identify a different instrument) that affects the economy. Second, in the presence of fractional reserve banking, the supply would need to respond to liquidity crises and act as a lender of last resort in order to safeguard financial stability. Third, there would need to be a system of checks and balances to keep the agent, ie the cryptocurrency issuer, accountable to the principal, ie society, which is not possible because cryptocurrencies are automatically and privately-issued. For these reasons, official currencies controlled by inflation-targeting independent central banks still appear to be a far superior technology than cryptocurrencies to provide the money functions.
The Banking Union is a framework composed of “Single Supervisory Mechanism （SSM）”, “Single Resolution Mechanism （SRM）” and “Deposit Guarantee Scheme （DGS）” and aims at strengthening regulation, observation and governance in the European financial sector. In the case that a bank goes into bankruptcy, it will be saved, without using public finance, between stockholders and creditors under the framework of banking union. Moreover, European Union （EU） integrates the responsibility of observation into the European Central Bank （ECB） and expects that ECB will be able to timely intervene banking system in member countries so that it can stop spreading financial crisis. On the other hand, European financial system is diversified and regional oriented in nature, reflecting its history, culture and policies. For example, in Germany, Landesbank/Sparkasse system, which is like a public bank owned by local government, and cooperative banks, which have close relationship with local businesses, has a larger share and influence. In France, large financial institutions such as Credit Agricole, BPCE group and Credit Mutuele, which are owned partly by public entity, make it possible to be both commercialization and localization at the same time by owning numerous small local banks under their umbrellas. In the Netherlands and Finland, which are economically successful in Euro zone, cooperative banks such as RaboBank and OP Group have also larger share and could keep sound banking even during European debt crisis. However, In Spain and Italy, which owns about 1/3 of bad loans in whole Euro zone, cooperative and saving banks also have larger share in their financial systems but it is criticized that its governance is one of major reasons causing financial crisis. Purpose of this paper is to overview how de-centralized financial system like saving banks and cooperative banks, which have larger influence in European countries, are overcoming the financial crisis in major European countries and to analyze and discuss effectiveness of both banking union and stability of regional financial system, emphasizing its importance as a stabilizer of money circulation in regional economy. This paper also tries to show the soundness of regional financial system during European debt crisis with recent business performance of cooperative banks which have decentralized financial structure and to complement precedent papers by indicating that characteristic of financial structure have some relationships with degree of financial crisis through comparing the characteristics of four major Euro countries such as Germany, France, Spain and Italy. （395 words）
A proof of balance plus transaction fees block-chain cash system as well as a proof of logarithmic stake block-chain system are proposed. Securities of both systems are analysed.
Revisiting analytically the notion of embeddedness and its connections with the concept of trust, this paper shows that contrary to Bitcoin’s premises and promises to be a trust-low or even trust-less currency, trust enters the system at many various levels and with different nuances. Applying a conceptual framework that conceives embeddedness as both the possible source and outcome of trust, it is pointed out that Bitcoin should better be regarded as doubly embedded: in technology and in its peculiar social structure. Due to the existence of computational and cognitive asymmetries within the system, in fact, trust is necessary for the very functioning of this new form of money, as well as for its future prospects.
