قیمت نفت، نرخ ارز و بازار سهام تحت عدم اطمینان و تغییر رژیم

We contribute to the ongoing literature on the interactions between oil prices, exchange rates and stock markets by considering the effects of economic policy uncertainty (EUP). Based on a VAR and a multivariate Markov switching vector autoregressive (MS-VAR) models, we show (i) significant interrelations between currency, oil and stock markets; (ii) relationships between the variables are rather non-linear; (iii) links between the variables change from one regime to the next, but they are stronger during volatile periods; and (iv) oil plays an active role in the transmission of price shocks to both the exchange rate and stock markets.
