 Abstract :
This paper proposes a systematic study of the degree of financial integration following the degree of trade integration according to Balassa’s (1961) classification, from preferential trading area to complete economic integration. To this end, we exploit all the information contained in interest rates and rely on the expectations hypothesis of the term structure of interest rates and real interest rate parity. These two conditions are empirically investigated on various regional trade agreements, using cointegration techniques by paying a special attention to potential breaks. Our results show that customs unions, corresponding to step 3 of the Balassa’s classification, seem to be a decisive threshold after which financial integration robustly takes place.
