Given the importance of monetary policy in the operation of a successful modern economy and the use of official interest rates as tools in its implementation, this study investigates the implications of changing bank concentration on the operation of the Interest Rate Pass Through (IRPT) of official rates to bank lending and deposit rates. This is an issue made more poignant by growing mergers, acquisitions and bank consolidation exercises around the world that have brought interest to their implications for economic performance. However, with contention high in the industrial organisation theory on the likely relationship between bank concentration and the IRPT, and the outcomes of empirical investigations producing conflicting evidence, the desire to investigate the issue in the African context necessitated a thorough empirical investigation of four African countries (South Africa, Botswana, Nigeria and Zambia). This study not only extended the investigation of the issue to the African context, but it merged different IRPT measurement techniques that had not been jointly applied to this particular issue, namely; Symmetric and Asymmetric Error Correction Models, Mean Adjustment Lags, Ordinary Least Squares estimations and Autoregressive Distributed Lag models. These measures of the IRPT were compared with three firm concentration ratios on two different levels of analysis, one, over the entire period and, another, through eight year rolling windows. The results reveal that bank concentration can sometimes be related to the speed and magnitude of the IRPT but that these relationships are not consistent amongst the countries, over the entire sample period or across the two levels of analysis, suggesting reasons why empirical results have arrived at contrasting conclusions. The results revealed more evidence of a relationship between bank concentration and the magnitude of the IRPT than between bank concentration and the speed of the IRPT. Furthermore, where relationships were identified there was evidence supporting both the structure conduct performance hypothesis and the competing efficient market hypothesis as the true representation of the relationship between bank concentration and the IRPT. The key implication of the result for African countries is that increased bank concentration through bank consolidation programmes should not be automatically regarded as detrimental to the effective implementation of monetary policy through the IRPT. Consequently,banking sector regulation need not stifle bank consolidation and growth to preserve monetary policy effectiveness. Rather, since the relationship cannot be neatly represented by a single theory or hypothesis each country must determine its own interaction between bank concentration and its IRPT before policies regarding the banking sector concentration and effective monetary policy, through the use of official interest rates, are determined.

This fact seems to be strongly correlated with high spreads and interest rate on bank loans charged by the Brazilian banking sector. The orthodox theory is the one that most deeply study this topic and point to five main reasons as determinants of different credit costs between countries: competition in the banking sector; macroeconomic environment; taxation, reserves requirement and mandated lending; and availability of information about borrowers. Assessing Brazil in the indicated items, there is notable improvement in almost all factors during de 2000s, however, despite of the cutbacks in interest rates and spreads, we can explain only partially the reduction observed and, in addiction, we note that the credit costs in Brazil are still high comparing to other countries. We understand that SELIC may explain the high level of Brazilian credit costs, because beyond affect directly the costs of funding, it represents a high cost of opportunity of offering credit, since SELIC remunerate part of Brazilian treasury bills, which become profitable, low risk and high liquidity assets / Apesar de ser um importante fator para o desenvolvimento das economias por propiciar liquidez ao sistema e financiar consumo e projetos de investimento, o mercado de crédito é pouco desenvolvido no Brasil quando comparado com as principais economias do mundo. Este fato parece ter forte correlação com os elevados spreads e taxas de juros praticadas pelo setor bancário brasileiro. A teoria ortodoxa convencional trata do tema e aponta para cinco principais fatores como determinantes das diferenças de custos de crédito entre os países: grau de competição do setor bancário; ambiente macroeconômico; tributação, requerimento de reservas e empréstimos subsidiados; e disponibilidade de informações sobre os mutuários. Ao avaliar o Brasil nos itens indicados, notamos sensível melhora em praticamente todos os fatores durante os anos 2000, entretanto, apesar das reduções das taxas de juros e spreads, consegue-se explicar apenas parte da queda verificada e, além disso, notase que os custos de crédito no Brasil ainda são elevados em relação a outros países. Entendemos que a taxa SELIC possa ser a explicação para os patamares ainda elevados dos custos de financiamento no Brasil, pois, além de influenciar diretamente os custos de captação, ela representa, para o setor bancário, um alto custo de oportunidade de se ofertar crédito por ser base para remuneração de parte dos títulos da dívida do governo brasileiro, tornando-os ativos rentáveis, de baixo risco e alta liquidez

Trenden inom världsekonomin har på senare år indikerat på en mognad där tillväxten ligger på låga tal historisk. Detta har tvingat centralbanker runt omkring jorden att drastiskt ta till åtgärder för att stimulera tillväxten. Reporäntan har använts som det mest centrala instrumentet för detta ändamål. Sverige är ett levande exempel på detta, där de har sänkt räntan lägre än den fruktade nollnivån och har i dagsläget en ränta på -0,5 %. Effekterna av reporänteförändringar på aktievärdering har studerats brett och den ackumulerade åsikten bland forskare är att räntan påverkar aktiemarknaden direkt. De historiska studierna som har utförts fokuserar på hur marknaden som helhet påverkas där de individuella företagseffekterna hamnar i skymundan. Därför har denna studie fokuserat på att undersöka dessa branschrelaterade effekter av en ränteförändring på individuella företag inom de valda branscherna. Detta område har undersökts med hjälp av en eventstudie.  Resultaten från studien visar på homogena effekter för mindre bolag där dessa får en större påverkan vid förändringar än stora bolag. Detta visar sig även mellan de olika branscherna. De observerade branscherna är sällanköpsvaror och dagligvaror, de branschspecifika effekterna som studien visar är att dagligvaror påverkas signifikant mer än sällanköpsvaror. Vidare visar resultatet att företagsstorlek har en större påverkan än branschtillhörighet, där small-cap bolag inom sällanköpsvaror har större påverkan än large-cap bolag inom dagligvaror. En negativ förändring går även att hänvisa till mer homogena rörelser för branscherna samt de olika storlekarna. Vidare gav positiva nyheter en mer heterogen rörelse där de mindre bolagen ej korrelerade med dem större. / In recent years, the trend in the world economy has indicated a maturity in growth which is low in historical terms. This has forced central banks around the world to drastically act to stimulate growth. The prime rate has then been used as the most central instrument for this purpose. Sweden is a living example of this as they have lowered interest rates below the dreaded zero level and currently have an interest rate of -0.5 %. The effects of prime rate changes on stock valuation have been studied widely, and the accumulated opinion among researchers is that interest rates directly affect the stock market. The historical studies that have been carried out focus on how the market as a whole is affected where individual effects on businesses end up in the dark. Therefore, this study has focused on investigating these industry-related effects of an interest rate change on individual companies in the chosen industries. The results from the study show homogenous effects for smaller companies, where the impact is greater on them in addition to larger companies. This is also apparent between the different industries. This area of concerns has been studied with an event study. The observed industries are consumer discretionary and commodities, the industry-specific effects shown by the study are that commodities are significantly more affected than consumer discretionarys’. Furthermore, the results show that company size is a greater indicator than industry due to the greater effect on small companies within consumer discretionary than on larger companies in the commodities sector. A negative change can also be referred to more homogeneous movements for the industries as well as the different business sizes. In addition, positive news gave a more heterogeneous move where the smaller companies did not correlate with the larger ones.
