The development of the market and the improvement in the climate for investments in the mid-1920s was mainly due to the efforts put in by the governments of the period to stabilize the economy. Foreign financiers invested considerable sums both in the form of refugee loans to the Greek state, and also financed big public works like drainage and irrigation as well as the expansion of the road and rail networks.
The international changes in the orientation of cross-border trade contributed to the circulation of capital. Compared to their counterparts in Greece, the capital cities of the world enjoyed relatively low interest rates, which basically enabled foreign entrepreneurial capital to pursue this course. After the economic crisis of 1929, traditional markets in the field of trade were replaced by new markets with the mechanism of clearing ( that is setting off in kind, without paying in exchange) as well as a developing local market. This method, despite its significant drawbacks, permitted the effective control of imports and exports by the state. In this way, imports were reduced to the absolute essentials (raw materials etc.), resulting in a decrease in the trade deficit from 47.6% in 1924 to 25.1% in 1939.
