NCO is "net capital outflow" so that means that money is leaving the country with a positive NCO. With fewer funds available, real interest rates will rise, making it more expensive to borrow within that country.
To directly answer this question though, if NCO are increasing it is most likely that the country is a net exporter, meaning their exports are higher than imports. To increase the production within the country, firms will increase their demand for loanable funds since a lot of business expansion (investment) is done with borrowed funds. So if firms increase their borrowing, there will be an increase in demand for loanable funds within the country.
This really only applies to a country with a single currency like the US or Canada. European countries could experience different relationships since many share a single currency and some might be net importers with postivie NCO as well due to intraEU trade.
