To counter the sharp appreciation of the Swiss franc that set in in the wake of the European sovereign debt crisis, on September 6, 2011, the Swiss National Bank announced to enforce a minimum EUR/CHF exchange rate of CHF 1.20. We find that the simple, though elegant model for the exchange rate...

Starting from the stylized fact that the Swiss franc is a safe haven currency, this paper focuses on the determinants of the Swiss franc during the lower bound regime from September 2011 to January 2015. We describe the Swiss franc as a function of global market risk fundamentals and find that...

In this paper, we model the exchange rate in a target zone by a so-called reflected Ornstein-Uhlenbeck process. A simulation-based maximum likelihood estimation strategy of the parameters involved in the model is proposed and studied. The model fits data on exchange rates in the European...

We present a model of a quot;softquot; exchange rate target zone and interpret it as a stylized description of the post-August 1993 ERM. Our central bank targets a moving average of the current and past exchange rates, rather than the exchange rate's current level, thus allowing the rate to move...

This paper analyzes the effects of changes in the Czech exchange rate mechanism on the volatility of the Czech spot exchange rate. While related studies draw the conclusion that exchange rate volatility decreased after the widening of the imposed fluctuation band, the results derived in the...

On 6 September 2011, a ceiling on the value of the Swiss franc was imposed, at CHF 1.2 per euro. With the continuous weakness of the euro area economy, this exchange rate limit was abandoned on 15 January 2015. This paper proposes a quasi-bounded process for the Swiss franc exchange rate...

This paper develops a new theoretical model with an asymmetric informal one-sided exchange rate target zone, with an application to the Swiss franc following the removal of the minimum exchange rate of CHF 1.20 per euro in January 2015. We extend and generalize the standard target zone model of...

This paper proposes a quasi-bounded process for exchange rate dynamics within a target zone, consistent with a credible exchange rate band in which the exchange rate cannot breach the strong-side limit while the weak-side limit is only accessible under restricted conditions of the relationship...

We formulate a mathematical model for the optimal control of the exchange rate. The control consists of a stochastic control, and an impulse control. We give general sufficient conditions for its solution. We consider a government that has two means of avoiding the foreign exchange rate...
