The impact of infrastructure bond yields on road infrastructure development: Evidence from Nairobi Metropolitan Region, Kenya. IOSR Journal of Business and Management (IOSR-JBM), 27(3 Ser. 8), 01–10. https://doi.org/10.9790/487X-27030801102278-487xhttps://ir-library.ku.ac.ke/handle/123456789/32016Research ArticleInfrastructure bonds are crucial for funding large-scale infrastructure initiatives, such as road construction, energy systems, and public transportation networks. Consequently, infrastructure bond yields represent the returns that investors receive for purchasing bonds issued by governments or corporations to finance infrastructure projects. They also represent the bond’s risk and return profile. This study sought to find out the effect of the Infrastructure bond yields on the performance of road projects in Nairobi Metropolitan Area, Kenya. The research employed a longitudinal research design to effectively address its objectives. The study population encompassed 18 road construction projects conducted between 2014 and 2022 in the area. Panel data for the bonds and projects performance were compiled from the Central Bank of Kenya; National Treasury; Ministry of Transport and Infrastructure, as well as the Kenya Urban Roads Authority. Data was analysed using descriptive statistics and inferential statistics aided by STATA ver.14.0. The findings of this study reveal a significant relationship between infrastructure bond yields and the performance of road projects in the Nairobi Metropolitan Region. Higher bond yields are associated with delays in project completion, suggesting that increased borrowing costs may restrict infrastructure financing, ultimately hindering progress in road development. Government agencies should implement policies that stabilize infrastructure financing costs, such as tax incentives for infrastructure bonds, improved public-private partnerships, and innovative funding mechanisms to enhance road project completion ratesenArticle
