This diploma thesis is focused on unconventional monetary policy tools that individual central banks introduced into practise as a response to the global financial crisis. It is about quantitative easing policy, foreign exchange interventions with exchange rate commitment and negative interest rates. This thesis also deals with classical tools of monetary policy such as open market operations, discount tools, minimum requirement reserve or foreign exchange interventions. The aim of the thesis is to document the development of central banks policy and then to examine relationship of selected assets in comparison with balance sheet of Federal reserve systems with help of correlation coefficient. The thesis also deals with the thought how should behave in the zero lower bound environment and what are the pitfalls of unconventional monetary policy.

La régulation bancaire doit être vue comme le fait d'encadrer et de contrôler l'activité bancaire, en la soumettant au respect des diverses normes, pour en maîtriser les risques afin de préserver la sécurité des déposants, la stabilité du système financier et les grands équilibres économiques. Pour arriver à cette fin, la régulation bancaire s'appuie essentiellement sur la réglementation et la supervision.Les systèmes bancaires domestiques étant devenus de plus en plus interdépendants, il apparaît nécessaire de faire face aux menaces de la même manière, de façon coordonnée au niveau international ou, à tout le moins, au niveau régional. C'est ainsi que la CEMAC et l'UEMOA se sont dotés au lendemain des crises de 1990 d'un dispositif de régulation marqué par une pléthore de réglementations et des organes de supervision communautaires. Depuis la crise de la dette survenue en Europe, la régulation de l'activité bancaire a évolué dans cette région avec la création de l'Union bancaire. Ceci dit, la supervision des établissements bancaires a été confiée à la Banque Centrale Européenne au sein de l' UE bien qu'elle demeure partagée avec les autorités nationales. Il s'agira pour nous, dans le présent travail, de comparer les dispositifs de régulation en vigueur dans les régions de la CEMAC, de l'UEMOA, de l'UE. On verra comment les régions de l'Afrique Centrale , de l'Afrique de l'Ouest et de l'Europe organisent la régulation bancaire en vue de préserver la stabilité des banques. Pour y parvenir il faudra comparer les différents organes chargés de la régulation et les principales règles de régulation qui existent dans ces régions. / Banking regulation should be seen as the act of monitoring and controling banking, by subjecting the compliance with various standards to control risks to preserve the security of depositors , the stability of the financial system and major economic balances. To achieve this, the banking regulation is based mainly on regulation and supervision. Domestic banking systems have become increasingly interdependent, it is necessary to deal with threats in the same way , in a coordinated manner at the international level or at least at the regional level . Thus CEMAC and UEMOA have adopted in the aftermath of the 1990 crisis a control device marked by a plethora of regulations and community oversight bodies . Since the debt crisis in Europe, the regulation of banking has evolved in this region with the creation of the banking union . That said, the supervision of banks has been entrusted to the European Central Bank within the EU although it remains shared with the national authorities.In the course of this work, our task will be to compare the existing control devices in the CEMAC region , UEMOA , EU . We shall review and find how the regions of Central Africa, West Africa and Europe organize banking regulation in order to preserve the stability of their banks. To achieve this goal, a comparison of the various bodies responsible for the regulation and the main regulatory rules that exist in these regions are deemed necessary.

Sverige rör sig mot ett kontantlöst samhälle i en takt som uppmärksammas internationellt. Det svenska betalningsväsendet kan komma att genomgå omfattande strukturella förändringar inom snar framtid. En av dessa förändringar kan antas vara införandet av den digitala centralbanksvalutan (CBDC) e-kronan. Då språnget mot det kontantlösa samhället börjat uttrycka sig i resten av världen är olika länders centralbanker mitt uppe i att reda ut de makroekonomiska effekter som en CBDC medför. Då e-kronan är ett nytt fenomen existerar det inte någon omfattande empirisk forskning, utan förhållandesättet är fortfarande teoretiskt. Vi undersöker därför de makroekonomiska effekter som kan tänkas uppstå vid införandet av en räntebärande e-krona från kort till lång sikt, samt diskuterar möjligheten för att använda e-kronan som ett penningpolitiskt styrmedel. Vi finner utifrån en modifiering av IS-MP-PC-modellen att en räntebärande e-krona som sätts i enlighet med inflationsmålet har liknande makroekonomiska effekter som styrräntan har idag. Vidare utvidgar vi en överlappande generationsmodell och visar på en undanträngning av reala tillgångar på lång sikt vid höga räntenivåer på e-kronan relativt till räntan på reala tillgångar i ett intergenerationellt sammanhang. / Sweden is moving towards a cashless society at an internationally recognized pace. The Swedish payment system may undergo extensive structural changes in the near future. One of these changes is assumed to be the introduction of the digital central bank currency (CBDC) e-krona. As the leap towards a cashless society has begun to manifest itself in the rest of the world, various countries' central banks are in the midst of figuring out the macroeconomic effects that a CBDC brings. As the e-krona is a new phenomenon, there is no extensive empirical research and the approach is still theoretical. We therefore investigate the macroeconomic effects that may arise from the introduction of an interest-bearing e-krona from the short to the long term and discuss the possibility of using the e-krona as a monetary policy instrument. By modifying the IS-MP-PC-model we find that an interest-bearing e-krona set in accordance with the inflation target has similar macroeconomic effects as the policy rate today. Furthermore, we extend an overlapping generations model and show a crowding out effect of real assets in the long run when the interest rate on the e-krona is high relative to the interest rate on real assets in an intergenerational context.

Diplomová práce se zabývá problematikou měnové politiky v Evropské unii, respektive v Evropské měnové unii. Samotnému vzniku Evropské měnové unie předcházelo dlouhé období integračních procesů a je spojováno se dvěma mezníky. Prvním mezníkem byl vznik Evropské centrální banky, která představuje jednu z nejdůležitějších institucí a je zodpovědná za provádění jednotné měnové politiky v eurozóně. Druhým důležitým momentem bylo zavedení společné evropské měny, eura. Navzdory podstatným obchodním výhodám spojených s přijetím eura se brzy ukázalo, že jednotná měnová politika nemusí vyhovovat všem zemím kvůli jejich odlišným ekonomickým potřebám a schopnostem, které vyžadují různou měnovou politiku. Tato práce se soustředí na současnou ekonomickou situaci v eurozóně se zvláštním důrazem na otázku dluhové krize.

Ma thèse étudie la pensée monétaire ainsi que les travaux de Ralph G. Hawtrey, Harry D. White et Robert Triffin, entre 1919 et 1960. Au cours des débats sur cette période, considérée comme fondatrice pour le système monétaire international, ces trois économistes ont été des personnalités clés qui ont influencé le cours de l’histoire monétaire. Premièrement, ils ont critiqué la théorie de l’étalon-or issue de la tradition ricardienne, en soulignant le caractère non-automatique et asymétrique du mécanisme d’ajustement de la balance des paiements. En s’articulant autour du rejet de cette tradition, les analyses de nos auteurs ont caractérisé les faiblesses liées au fonctionnement du système monétaire international. Deuxièmement, bénéficiant de leurs positions au Trésor américain et britannique, au FMI ou encore à la Fed, ces économistes ont exercé une influence sur les réformes en œuvrant pour une consolidation de la coopération monétaire internationale dans un régime de changes fixes. / My PhD dissertation studies Ralph G. Hawtrey’s, Harry D. White’s and Robert Triffin’s monetary thought and works between 1919 and 1960. Actively participating to key institutions which shaped the international monetary system – the British Treasury for Hawtrey, the US Treasury for White and the Fed and the IMF in the case of Triffin – those economists influenced the course of monetary theory and history. They both wrote on the non-automatic and asymmetric nature of the balance of payments adjustment mechanism, and formulated an original critic towards the classical Ricardian gold standard theory. Structured around the rejection of this classical theory, the authors’ analysis pointed out the weaknesses of the international monetary system. Since then, all of their reform proposals were grounded on the strengthening of monetary cooperation under a fixed exchange rates system.

The author sketches the development and legal status of the European Currency Unit (ECU), the predecessor of today's European single currency Euro, and asks whether from the perspective of (former) German monetary law, this currency unit had to be looked at not as a domestic currency ("Deutsche Mark"), but rather as a foreign one.

Ideal Crisis Management Mechanism for Credit Institutions and Investment Firms in the European Union Abstract: The 2007-8 financial crisis brought about the most severe economic contraction since the Great Depression. Regulators on both sides of the Atlantic were taken aback and soon realized that they had no tools to deal with distressed banks and other financial services firms, failure of which could undermine financial stability not only within individual states, but also on a global scale. As a result, central banks of in particular the United States and the Eurozone became the most important actors in the fight against the unfolding crisis and de facto the only "governmental agencies" capable of swift and decisive measures. Their timely and vigorous reaction most likely warded off the collapse of the global financial system, though it was not without controversies. These controversies are analyzed in this dissertation in order to find out what role should central bank have during financial crisis. Governments followed central banks with massive bank bailouts. In many countries, governments went beyond liquidity provision and nationalized their banks, which threatened their own solvency. Although the global financial system has been largely restored in the last decade, it has been achieved at huge...

Under de senaste 14 åren har den svenska kronan genomgått en period av depreciering mot många andra valutor. Detta väcker frågan om vad som ligger till grund för växelkursens rörelser. Denna studie ämnar därför undersöka om det öppna ränteparitetsvillkoret kan förklara relationen mellan förändringar i växelkurser och räntedifferenser på kort sikt. För att undersöka frågan har två regressionsmodeller konstruerats med räntedifferenser som förklarande variabel och fluktuationer i växelkursen som beroende variabel. Studien begränsas till att undersöka förhållandet mellan Sverige som inhemskt land och Euroområdet samt USA som utländska områden/länder. Eftersom euron och den amerikanska dollarn kategoriseras som “safe haven” valutor inkluderas safe haven teorin som en sekundär aspekt i analysen. Studien använder månadsvis data över perioden 1999-2022. Regressionsmodellernas resultat visar en korrelation som är något avvikande från det öppna ränteparitetsvillkoret. Regressionsmodellerna presenterar icke-signifikanta resultat och studiens slutsats är därmed att undersökningen inte presenterar tillräckligt med bevis för att säkerställa att den sanna relationen mellan räntedifferenser och förändringar i växelkursen skiljer sig signifikant från ränteparitetsvillkoret. / Over the past fourteen years the Swedish krona has undergone a period of depreciation against many other currencies. This raises the question of what factors drive the movements of the exchange rate. This study intends to examine if the open interest parity condition can explain the relationship between fluctuations in the exchange rate and the interest rate differentials in the short term. To examine the subject two regression models have been constructed with the interest rate differentials as the explanatory variable and fluctuations in the exchange rate as the dependent variable. The research is narrowed down to examine the relationship between Sweden as the domestic country and the euro area and USA as foreign areas/countries. As the euro and the american dollar are categorized as “safe haven” currencies the safe haven theory is also included as a secondary aspect of the analysis. The study utilizes monthly data over the period 1999-2022. The results of the regression models show a correlation that deviates somewhat from the open interest parity condition. The regression models present non-significant results and the study's conclusion is thus that the study does not present enough evidence to ensure that the true relationship between interest rate differentials and changes in the exchange rate differs significantly from the interest parity condition.

Bakgrund: Med ökade styrräntor och stigande inflation har det blivit viktigt att förstå hur dessa förändringar påverkar ekonomin, företag och aktiemarknaden. Forskning visar att räntebesked kan påverka både aktiemarknaden och banksektorn med effekter på avkastning och volatilitet. Bankerna har som bekant en särskild funktion i den svenska ekonomin genom att svara för finansiering och betalningstjänster till näringsliv och offentlig sektor. Syfte: Studiens syfte är att undersöka de effekter som uppstår vid förändringar i Riksbankens styrränta på den svenska aktiemarknaden och inom banksektorn.  Metod: En kvantitativ eventstudie med en deduktiv forskningsansats har genomförts. Undersökningen består av sju olika observationer på ränteförändringar av aktier på den svenska OMX Large Cap-listan. De olika observationerna är räntehöjningar rapporterade av Riksbanken mellan åren 2019-2023.  Teori: Studien utgår från den effektiva marknadshypotesen vilket kompletterats med tidigare forskning om ränteförändringar och bankers påverkan av räntehöjningar.  Slutsatser: Studien finner inte bevis för statistiskt signifikant samband mellan Riksbankens räntehöjningar och den svenska aktiemarknaden. Inom banksektorn fanns inte heller tillräckliga bevis för att visa på en abnormal avkastning vid tillkännagivandet av ett räntebeslut. Resultatet stöds av den effektiva marknadshypotesen. De få resultat som visade på abnormal avkastning bör därför studeras vidare. Externa faktorer borde inkluderas för att förklara skillnaderna i reaktionerna på den svenska aktiemarknaden. / Background: With increasing policy rates and rising inflation, understanding how these changes impact the economy, businesses, and the stock market has become crucial. Research has shown that interest rate announcements can affect both the stock market and banks, influencing returns and volatility. Banks play a central role in the Swedish economy by offering financing and payment services. Purpose: This study aims to examine the effects of changes in the Swedish central bank's policy rate on the Swedish stock market and banking sector. Methodology: A quantitative event study with a deductive research approach was conducted. The study consists of seven different observations on interest rate changes affecting stocks listed on the Swedish OMX Large Cap List. These observations cover interest rate hikes reported between 2019 and 2023. Theory: The study is based on the efficient market hypothesis, complemented by previous research on interest rate changes and the impact of rate hikes on banks. Conclusions: The study shows no significant relationship between Swedish central bank's interest rate hikes and the overall stock market. Similar findings were observed within the banking sector. This can be explained by the efficient market hypothesis, which suggests that all relevant information is already reflected in stock prices. The efficient market hypothesis also supports the lack of market reactions, thus future research should consider external factors that could explain differences in reactions within the Swedish stock market.

[pt] Como (1) aponta, a previsibilidade acerca da política monetária pode melhorar a eficácia da política de estabilização de um Banco Central. Nesse artigo, procuramos reduzir a incerteza a respeito de um instrumento de Forward Guidance do Banco Central norte-americano (o Federal Reserve) estimando distribuições de probabilidade completas sobre todas as associações possíveis entre seus membros e o dot plot de taxa de juros para cada reunião. Nossa contribuição para a literatura ocorre em duas frentes: primeiro, propomos um algoritmo Bayesiano geral que estima essas hipóteses de associação entre agentes e ações sempre que elas não são observadas. Além disso, elaboramos uma maneira nova e menos subjetiva para quantificar textos em dados numéricos, usando Alocação Latente Dirichlet (LDA) e modelos econométricos de seleção. Esse método apresenta algumas características desejáveis como uma correlação positiva entre o presidente do FOMC e o resto do comitê, e um ordenamento na postura de política monetária que reflete, ainda que parcialmente, visões de analistas de mercado a respeito desse espectro entre membros mais duros e mais lenientes com a taxa de juros. Nosso algoritmo de rastreamento de alvos também tem bom desempenho num ambiente simulado, no sentido em que, em média, considera como mais provável a verdadeira associação entre membros e dots. Usando dados reais de discursos individuais e dots, ele também consegue atribuir a maior probabilidade para a associação correta na única reunião em que ela é conhecida de fato. / [en] As (1) points out, monetary policy predictability can enhance a Central Bank stabilization policy efficacy. In this paper we aim to reduce uncertainty about one Federal Reserve forward guidance instrument by estimating full association probabilities distributions between members and the interest rate dot plot for each FOMC meeting. Our contribution to the literature is twofold: first, we propose a general Bayesian algorithm which estimates these association hypotheses between agents and actions whenever they are not observed. Second, we elaborate a novel and less subjective technique for quantifying text into data, using Latent Dirichlet Allocation (LDA) and shrinkage econometric tools. This method shows some desirable features such as positive correlation between the FOMC chair and the rest of the committee, and a policy stance ordering which partially reflects analysts and market participants views on this hawk-dove spectrum. Our tracking algorithm performs successfully in a simulated environment, in a sense that it on average considers the correct member-to-dot association as the most likely one. Using real data on speeches and Fed dots, it is also able to attribute the highest probability to the correct assignment hypothesis in the only meeting it is known for sure.
