In the 21st century these are all still excellent ways to import skills in banking in general and risk management in particular. Limiting foreign presence may be the worst thing for local banks - insulating them from competition and making the import of valuable human capital and expertise more costly.
Risk management implies significant limits on the ability of highly leveraged financial institutions such as banks to provide badly needed venture capital; it implies that financial systems need more than banks. They need non-bank financial institutions that are less leveraged than banks and have much longer term liabilities. They also need functioning capital markets, including foreign providers of long-term and equity capital.
