This paper employed variant GARCH models to examined official, interbank and Bureau de change returns volatilities. Using monthly exchange rate of Naira/USD from January 2004 to September 2020 (2004:1-2020:9), the returns were not normally distributed and stationary at level. Ljung-Box Q statistic and Ljung-Box Q2 statistics of power transformed using power 0.25, 0.5 and 0.75 for conditional heteroscedasticity for lags of 6, 12 and 20 indicated present of conditional heteroscedascity in all returns. The study found exchange rate volatility in Official, interbank and Bureau de change exchange rate returns were persistent. However, Bureau de change return was more persistent while official exchange rate return was the least persistent. Also, leverage effect exist in all the three exchange rate returns and asymmetric model were the best model for estimating exchange rate return while IGARCH was the worst model to estimate exchange rate return in Nigeria. There is need to incorporate news impact when developing exchange rate policy by monetary authority in Nigeria.

As a result of the oil price shocks, the 1979 revolution, and the eight-year war with Iraq, fundamental changes have taken place in Iran's foreign exchange position as well as in its exchange rate policy. The viable data over the period 1979–1980 to 1988–1989 clearly show that, despite the revolutionary rhetoric, very little has been done to reduce the country's dependence on oil exports as a source of foreign exchange and government revenues. Instead, in the face of falling oil revenues and the country's increasing international isolation, coupled with the regime's unwillingness to incur foreign debt, the government has adopted a severe ‘import compression’ policy through selective tariffs and quotas, strict control of private and government imports by means of import licenses, and the imposition of foreign exchange allocations on government agencies. The result has been an ever-rising premium on the U.S. dollar in the ‘black’ market, a highly overvalued official exchange rate, a substantial increase in rent-seeking activities at the expense of production, a severe misallocation of resources, and loss of output and industrial capacity.

This paper examines the exchange rate volatility with GARCH-type model of the daily exchange rate return series from January 2012 – August 2016 for Naira/Chinese Yuan, Naira/India Rupees, Naira/Spain Euro, Naira/UK Pounds and Naira/US Dollar returns. The studies compare estimates of variants of GARCH (1, 1), EGARCH (1, 1), TGARCH (1,1) and GJR-GARCH (1,1) models. The result from all models indict presence of volatility in the five currencies and equally indicate that most of the asymmetric models rejected the existence of a leverage effect except for models with volatility break. For GARCH (1, 1), GJR-GARCH (1, 1,) EGARCH (1,1) and TGARCH (1, 1), it was observed that India have the best exchange rate with the highest log-likelihood (Log L) and the lowest AIC and BIC followed by USA, China, Spain and United Kingdom respectively. The four models was later compared for the exchange rates of the five countries under consideration i.e. China, India, Spain, UK and USA  to select the best fitted model for each country and it was discovered that GJR-GARCH (1,1) is the best fitted model for all the countries followed by GARCH (1,1), TGARCH (1,1) and EGARCH (1,1) in that order.

AbstractPublic foreign currency borrowing is a common problem of emerging markets. Scholars named it the original sin of foreign debt. It has a proven negative influence on economic growth and development, undermining financial stability, and increasing the probability of monetary crises. The roots of the original sin often lay in emerging markets’ institutional underdevelopment, with low-quality monetary policy, inappropriate exchange rate regime choice, and exchange rate mismanagement being stated among the most important causes. This paper evaluates the influence of the exchange rate policy on the emission of foreign currency sovereign bonds in emerging markets. The relationship is estimated using panel data and GMM approach, with exchange rate regime type (both de jure and de facto) and real exchange rate volatility serving as explanatory variables. The findings reveal that fixed exchange rate regime and high real exchange rate volatility is promoting the foreign currency borrowing. Thus countries that want to reduce the burden of the original sin should lean towards a more flexible exchange rate policy while maintaining their real exchange rate stable.

After the financial crisis at the end of the 1990 s many countries rejected fixed exchange rate policy. However actually they failed to proceed to announced "independent float" exchange rate arrangement. This might be due to the "fear of floating" or an irreversible result of inflation targeting central bank policy. In the article advantages and drawbacks of fixed and floating exchange rate arrangements are systematized. Features of new returning to exchange rates stabilization and possible risks of such policy for Russia are considered. Special attention is paid to the issue of choice of a "target" currency composite which can minimize external inflation pass-through.

The Bank of Russia intends to introduce inflation targeting policy and exchange rate free floating regime in three years. Exogenous shocks absorption which stabilizes the real sector of economy is usually considered to be one of the advantages of free floating exchange rate policy. However, our research based on the analysis of 25 world largest economies exchange rates and industrial production during the crisis of 2008-2009 does not confirm this hypothesis. The article also analyzes additional risks associated with free floating exchange rate regime in Russia and presents some arguments in favor of managed floating exchange rate regime.
