Financial globalization affects agricultural finance through the foreign exchange channel and the transfer of disturbances within financial systems, as well as a decrease in overall economic activity abroad. International external factors modify the nature, objectives and instruments of the national macroeconomic policy, and thus, in the narrowest perspective, the combination of fiscal and monetary policy. In wider terms, macroeconomic policy today must also take account of the financial stability of the state. These are all parameters given for financial policy in agriculture, which i.a. decrease the effectiveness of fiscal and monetary multipliers, and in consequence reduce marginal and average effectiveness of financial interventionism. The programmes enhancing fiscal and monetary expansion in agriculture should therefore be prepared with great caution and regular monitoring should cover the sector’s debt, prices on the land and lease market, mechanisms of agricultural price transmission, creating margins and values in the supply chains, and the risk of speculative bubbles in the area of agricultural assets and agri-food products.
