 New international borders separated Hungary's industrial base from its sources of raw materials and its former markets for agricultural and industrial products.Its new circumstances forced Hungary to become a trading nation.Hungary lost 84 percent of its timber resources, 43 percent of its arable land, and 83 percent of its iron ore. Because most of the country's prewar industry was concentrated near Budapest, Hungary retained about 51 percent of its industrial population, 56 percent of its industry, 82 percent of its heavy industry, and 70 percent of its banks.
