Este estudo teve como objetivo investigar se algumas situações específicas do Brasil podem contribuir para que as empresas apresentem índices de liquidez ainda maiores, tais como a possibilidade de captação de recursos de baixo custo e aplicação à taxas mais altas e a existência de fatores que resultam na discrepância entre lucro e geração de caixa das companhias. Foram examinadas as proxies para estas situações através de um estudo em painel com 288 empresas não financeiras de capital aberto no período de 1997 a 2006 com a inclusão de outras variáveis que explicam as variações no nível de liquidez relacionadas aos motivos de precaução, transação, especulação e assimetria de informação. Os principais resultados sugerem que o nível de liquidez nas firmas brasileiras é maior nas empresas que possuem algum tipo de benefício fiscal e/ou conseguem financiamentos a custos reduzidos, medido pela acessibilidade a outros mercados para captação de recursos (dummy ADR).

Currencies that are at a forward premium tend to depreciate. This `forward-premium puzzle' is an egregious deviation from uncovered interest parity. We document the properties of the carry trade, a currency speculation strategy that exploits this anomaly. This strategy consists of borrowing low-interest-rate currencies and lending high-interest-rate currencies. We first show that the carry trade yields a high Sharpe ratio that is not a compensation for risk. We then consider a hedged version of the carry trade, which protects the investor against large, adverse currency movements. This strategy, implemented with currency options, yields average payoffs that are statistically indistinguishable from the average payoffs to the standard carry trade. We argue that this finding implies that the peso problem cannot be a major determinant of the payoff to the carry trade.

Lower-interest-rate currencies tend to depreciate relative to higher-interest-rate currencies. This observation is inconsistent with a popular theory, uncovered interest parity (UIP). According to market participants' views, this is caused by the carry-trade activities in a low-volatility environment. This paper investigates how exchange rate volatilities influence the failure of UIP by using a regime-switching model, which is less restricted than those used in the literature. We estimate this model using a new method of Bayesian Gibbs sampling, which enables us to examine higher-frequency state transmissions and, at the same time, avoid possible estimation biases arising from the use of overlapping data. The main findings are as follows. First, statistical tests support our model in comparison with the alternatives. The evidence suggests that regime switches in exchange rate returns should be interpreted as switches in the relationship between the returns and interest rate differentials, which may be interpreted as switches between the carry trade and its unwinding. Second, low-interest-rate currencies appreciate less frequently, but once it occurs, its movement is faster than when they depreciate. This may be because the appreciation is influenced by a rapid unwinding of the carry trade. Third, a low volatility tends to cause UIP failure. In fact, the reverse is also true. That is, UIP failure contributes to maintaining a lower-volatility environment, which may imply that a high volatility does not tend to occur until an unwinding of the carry trade. These results imply that the low-volatility environment and UIP failure are mutually dependent. Finally, the second and third findings are more evident for shorter maturities, and this may imply that UIP failure is influenced by short-term speculations. All these results are consistent with market participants' views: the short-term carry trade in a low-volatility environment and its rapid unwinding substantially influence exchange rates.

De todas as anomalias documentadas na literatura de finanças internacionais, a sistemática violação da Paridade Descoberta de Juros, ou como é mais conhecida – viés nas taxas futuras câmbio - é sem dúvida um assunto no campo de finanças internacionais que chamou muita atenção e gerou inúmeros estudos nos últimos 30 anos. A questão tratada neste trabalho é se estratégias designadas a explorar a violação da Paridade Descoberta de Juros são lucrativas o suficiente de forma a torná-las uma nova classe de ativos entre os investidores no mercado de câmbio, principalmente os especuladores. Segundo um relatório do Bank for International Settlements (BIS) de 2004, o mercado de moedas tornou-se uma nova classe de ativos por duas razões: violação sistemática da Paridade Descoberta de Juros e alterações macroeconômicas que geraram movimentos de valorização ou desvalorização de longa duração. Apresentamos primeiramente uma revisão da extensa literatura que trata da violação da Paridade Descoberta de Juros e posteriormente um estudo sobre tal violação para uma série de moedas escolhidas conforme sua relevância no volume de negociações médias diárias no mercado de câmbio internacional. Observamos que a violação, assim como já evidenciada em outros estudos, realmente existiu tanto para países desenvolvidos como para países em desenvolvimento. A parte final do trabalho mostrou que as operações destinadas a explorar tal violação não são lucrativas quando analisadas do ponto de vista de uma única moeda. Apesar disso, quando se utilizam modelos de otimização de carteiras, percebem-se não somente retornos comparáveis a outras classes de ativos comumente utilizadas pelos especuladores, mas também com uma relação risco retorno sensivelmente maior. Concluiu-se então que carteiras ótimas de moedas designadas a explorar a violação da hipótese de mercado eficiente são lucrativas, e tal prática pode realmente explicar o aumento nas negociações diárias de diversas moedas nos últimos anos.

The carry trade strategy involves selling forward currencies that are at a forward premium and buying forward currencies that are at a forward discount. We compare the payoffs to the carry trade applied to two different portfolios. The first portfolio consists exclusively of developed country currencies. The second portfolio includes the currencies of both developed countries and emerging markets. Our main empirical findings are as follows. First, including emerging market currencies in our portfolio substantially increases the Sharpe ratio associated with the carry trade. Second, bid-ask spreads are two to four times larger in emerging markets than in developed countries. Third and most dramatically, the payoffs to the carry trade for both portfolios are uncorrelated with returns to the U.S. stock market.

I nära tio år har främst amerikanska placerare utnyttjat strategin carry trade för att skapa positiva avkastningar. Strategin innebär att lån tas på en marknad med låga räntor för att sedan placeras på en annan marknad med högre räntor. Det är främst de japanska och amerikanska räntemarknaderna som har använts. Syftet med uppsatsen är att utreda om det går att få en positiv avkastning vid carry trade-affärer. Vi kommer även att belysa vilka risker som uppstår vid dessa investeringar, samt undersöka vad som kan göras för att minimera de risker som uppstår. Genom att studera andra länder med betydande räntedifferenser vill vi även utreda om denna strategi går att tillämpa på andra ränte- och valutamarknader än Japan och USA. För att uppfylla syftet har en kvantitativ studie genomförts baserad på sekundärdata, där vi skapat olika fiktiva affärer över tre tidsperioder för att kunna räkna ut och jämföra avkastningar. Vi har även undersökt olika hedgingstrategier för att se om det är något som en aktör kan använda sig av på ett effektivt sätt vid nämnda affärer. I teorikapitlet tar vi upp två relevanta teorier för arbetet, uncovered interest rate parity och covered interest rate parity. Den första teorin säger att om två länders räntor skiljer sig åt förväntas växelkursen mellan ländernas valutor att på sikt helt och hållet ta ut ränteskillnaden. Den andra teorin säger att en riskfri investering, oavsett land, alltid ska ge samma avkastning. Resultatet från undersökningen visar att teorin uncovered interest rate parity stämmer dåligt överens med vår empiri. I studien har vi funnit att det är möjligt att skapa positiva avkastningar om affärerna är riskfyllda. Covered interest rate parity motsvarar däremot empirin i mycket hög grad. Undersökningen har inte resulterat i några lämpliga metoder att använda för att hedga carry trade-affärer mot valutarisken. Studien visar även på att det går att göra lyckade carry trade-affärer på andra marknader än Japan och USA.

La liquidazione diffusa di posizioni di carry trade è risultata evidente nel corso degli ultimi mesi. Quali conseguenze ha avuto sulla performance degli ETF nonché sulle attività in tali fondi e in altri prodotti strutturati basati su questa strategia?

Currencies that are at a forward premium tend to depreciate. This `forward premium-depreciation anomaly' represents an egregious deviation from uncovered interest parity. We document the returns to currency speculation strategies that exploit this anomaly. The first strategy, known as the carry trade, is widely used by practitioners. This strategy involves selling currencies forward that are at a forward premium and buying those that are at a forward discount. The second strategy relies on a particular regression to forecast the payoff to selling currencies forward. We show that these strategies yield high Sharpe ratios which are not a compensation for risk. However, these Sharpe ratios do not represent unexploited profit opportunities. In the presence of microstructure frictions, spot and forward exchange rates move against traders as they increase their positions. The resulting `price pressure' drives a wedge between average and marginal Sharpe ratios. We argue that marginal Sharpe ratios are zero even though average Sharpe ratios are positive. We display a simple microstructure model that simultaneously rationalizes `price pressure' and the forward premium-depreciation puzzle. The central feature of this model is that market makers face an adverse selection problem that is less severe when, based on public information, the currency is expected to appreciate

We study how capital controls and domestic macroprudential policy tame credit supply booms, either directly or by enhancing the local bank-lending channel of monetary policy. We exploit credit registry data and the introduction of capital controls on foreign exchange (FX) debt inflows and increase of reserve requirements on domestic bank deposits in Colombia during a boom. We find that capital controls strengthen the bank-lending channel. Increasing the local monetary policy rate widens the interest rate differential with the U.S.; hence, relatively more FX-indebted banks carry-trade cheap FX-funds with expensive peso lending, especially towards riskier firms. Capital controls tax FX-debt and break the carry-trade. Differently, raising reserve requirements on domestic deposits directly reduces credit supply, particularly for riskier firms, rather than enhancing the bank-lending channel. Importantly, banks differentially finance credit with domestic vis-à-vis FX-financing; hence, capital controls and domestic macroprudential policy complementarily mitigate the credit boom and related bank risk-taking.
