This paper develops a barrier-option pricing model in which the exchange rate follows a mean-reverting lognormal process. The corresponding closed-form solutions for the barrier options with time-dependent barriers are derived. The numerical results show that barrier option values and the...

The present paper is meant to describe the finite differences methods necessary to determine the value of financial options. In addition is presented the mathematic model of rating European type options. Value determination of an option is made through solving an equation with derivatives....

This paper explores the usefulness of currency futures-spot basis in predicting spot rate changes and currency futures returns. We conjecture that the currency risk premium may be an important component of the basis for long-maturity futures contracts, but may not be so for short-maturities....

Measuring and managing exchange rate risk exposure is important for reducing a firm's vulnerabilities from major exchange rate movements, which could adversely affect profit margins and the value of assets. This paper reviews the traditional types of exchange rate risk faced by firms, namely...

A typical strategy used by speculators to launch an attack on a fixed exchange regime is the use of forward markets. Central banks also intervene in forward markets to counter speculation. This paper addresses the question of how an attack is launched on the forward market, and what the optimal...

A common specification about the behavior of foreign exchange spot and futures prices is that they follow continuous diffusion processes. The empirical regularities uncovered from daily and weekly currency futures data, however, cast doubts on the validity of this model. First, contrary to the...

Currency option implied volatility predicts more efficiently exchange rate volatility for the Polish zloty relative to the Czech koruna, reflecting differences in the frequency of central bank intervention in the foreign exchange market. A GARCH model shows a positive impact of the introduction...

This paper aims to identify appropriate option contract specifications for effective central bank exchange market intervention. Option contract specifications determine the impact of options on the underlying asset or currency, and hence their actual effect on asset price or currency volatility...

The effects of the Exchange Rate Mechanism (ERM) of 1991-1993 on currency markets are examined. It is shown that the mechanism has led to a regime shift going from the 1980s to the 1990s. The floating exchange rates of the 1980s are associated with the forward premium puzzle (FPP) in spot...

This paper examines the historical predictive power of future spot spread in estimating currency changes. Currency futures and spot rates over the last two decades are examined. Results show that as forecast horizon of currency depreciation increases, the slope coefficients become less positive,...
