In Costa Rica, publicly-owned banks have been available for so long and work so well that people take for granted that any country that knows how to run an economy has a public banking option. Costa Ricans are amazed to hear there is only one public depository bank in the United States (the Bank of North Dakota), and few people have private access to it.
So says political activist Scott Bidstrup, who writes:
For the last decade, I have resided in Costa Rica, where we have had a “Public Option†for the last 64 years.
There are 29 licensed banks, mutual associations and credit unions in Costa Rica, of which four were established as national, publicly-owned banks in 1949. They have remained open and in public hands ever since—in spite of enormous pressure by the I.M.F. [International Monetary Fund] and the U.S. to privatize them along with other public assets. The Costa Ricans have resisted that pressure—because the value of a public banking option has become abundantly clear to everyone in this country.
During the last three decades, countless private banks, mutual associations (a kind of Savings and Loan) and credit unions have come and gone, and depositors in them have inevitably lost most of the value of their accounts.
But the four state banks, which compete fiercely with each other, just go on and on. Because they are stable and none have failed in 31 years, most Costa Ricans have moved the bulk of their money into them. Â Those four banks now account for fully 80% of all retail deposits in Costa Rica, and the 25 private institutions share among themselves the rest.
According to a 2003 report by the World Bank, the public sector banks dominating Costa Rica’s onshore banking system include three state-owned commercial banks (Banco Nacional, Banco de Costa Rica, and Banco Crédito AgrÃcola de Cartago) and a special-charter bank called Banco Popular, which in principle is owned by all Costa Rican workers. These banks accounted for 75 percent of total banking deposits in 2003.
In Competition Policies in Emerging Economies: Lessons and Challenges from Central America and Mexico (2008), Claudia Schatan writes that Costa Rica nationalized all of its banks and imposed a monopoly on deposits in 1949. Effectively, only state-owned banks existed in the country after that. The monopoly was loosened in the 1980s and was eliminated in 1995. But the extensive network of branches developed by the public banks and the existence of an unlimited state guarantee on their deposits has made Costa Rica the only country in the region in which public banking clearly predominates.
Scott Bidstrup comments:
By 1980, the Costa Rican economy had grown to the point where it was by far the richest nation in Latin America in per-capita terms. It was so much richer than its neighbors that Latin American economic statistics were routinely quoted with and without Costa Rica included. Growth rates were in the double digits for a generation and a half.  And the prosperity was broadly shared. Costa Rica’s middle class – nonexistent before 1949 – became the dominant part of the economy during this period.  Poverty was all but abolished, favelas [shanty towns] disappeared, and the economy was booming.
This was not because Costa Rica had natural resources or other natural advantages over its neighbors. To the contrary, says Bidstrup:
At the conclusion of the civil war of 1948 (which was brought on by the desperate social conditions of the masses), Costa Rica was desperately poor, the poorest nation in the hemisphere, as it had been since the Spanish Conquest.
The winner of the 1948 civil war, José “Pepe†Figueres, now a national hero, realized that it would happen again if nothing was done to relieve the crushing poverty and deprivation of the rural population.  He formulated a plan in which the public sector would be financed by profits from state-owned enterprises, and the private sector would be financed by state banking.
A large number of state-owned capitalist enterprises were founded. Their profits were returned to the national treasury, and they financed dozens of major infrastructure projects.  At one point, more than 240 state-owned corporations were providing so much money that Costa Rica was building infrastructure like mad and financing it largely with cash. Yet it still had the lowest taxes in the region, and it could still afford to spend 30% of its national income on health and education.
A provision of the Figueres constitution guaranteed a job to anyone who wanted one. At one point, 42% of the working population of Costa Rica was working for the government directly or in one of the state-owned corporations.  Most of the rest of the economy not involved in the coffee trade was working for small mom-and-pop companies that were suppliers to the larger state-owned firms—and it was state banking, offering credit on favorable terms, that made the founding and growth of those small firms possible.  Had they been forced to rely on private-sector banking, few of them would have been able to obtain the financing needed to become established and prosperous.  State banking was key to the private sector growth. Lending policy was government policy and was designed to facilitate national development, not bankers’ wallets.  Virtually everything the country needed was locally produced.  Toilets, window glass, cement, rebar, roofing materials, window and door joinery, wire and cable, all were made by state-owned capitalist enterprises, most of them quite profitable. Costa Rica was the dominant player regionally in most consumer products and was on the move internationally.
