We thoroughly describe the workings of the Brazilian interbank exchange rate market: agents, products, regulation, operation and risks. We analyse the recent evolution of the exchange rate market and came to a negative evaluation of the current exchange rate trading system, thereby suggesting an...

The cost of systemic risk in the over-the-counter (OTC) derivatives market is described and estimated. Modern portfolio theory (MPT), applied to OTC derivatives, predicts this cost, which has been growing since 1970. This cost grew because Congress blocked MPT's predicted market forces. Without...

Over-the-counter (OTC) traders cannot pursue the two fundamental objectives of portfolio management, the identification of portfolio market risk and return and its diversification. The result of this major market shortcoming is a complex, systemically risky market disequilibrium. The tradable...

We develop a general equilibrium model with intermediaries at the heart of international financial markets. In our model, intermediaries bargain with their customers and extract rents for providing access to foreign claims. The behavior of intermediaries, by tilting state prices, generates an...

We develop a general equilibrium model with intermediaries at the heart of international financial markets. Global intermediaries bargain with households and extract rents for providing access to foreign claims. The behavior of intermediaries, by tilting state prices, breaks monetary neutrality...

We discuss the idea of a purely algorithmic universal world iCurrency set forth in: "https://ssrn.com/abstract=2542541" https://ssrn.com/abstract=2542541 and expanded in: "https://ssrn.com/abstract=3059330" https://ssrn.com/abstract=3059330 in light of recent developments, including Libra. Is...

We discuss the pros of adopting government-issued digital currencies as well as a supranational digital iCurrency. One such pro is to get rid of paper money (and coinage), a ubiquitous medium for spreading germs, as highlighted by the recent coronavirus outbreak. We set forth three policy...

The paper presents a method of computing the risk neutral probability distribution of future exchange rates from the prices of currency options. The method is applied to estimate the risk neutral ex ante probability of a realignment of the pound sterling against the mark in 1992. The computation...

Risk reversals are a combination of options from which price information about market expectations of future exchange rates can be extracted. This paper describes a procedure for estimating the market's perceived probability distribution of future exchange rates from the prices of risk reversals...
