The insurance industry’s growing share of the global financial sector in both developed and developing countries has moved focus to the insurance-growth relationship. As a result, the study looked at the effect of insurance on Nigerian economic growth from 2007 to 2021. The study’s goals were to look at the impact of life, and total insurance premiums on the growth of the Nigerian economy after the insurance regulations and reforms were implemented in 2006. Ex-post facto analytical research design was adopted in this work. The National Bureau of Statistics and the Central Bank Statistical Bulletin provided secondary data. The logarithm was used to alter the data. Ordinary Least Square regression technique was used to analyze the data. According to the findings, non-life gross premium has a considerable positive influence on real GDP, life gross premium has no significant effect on real GDP, and there is a significant positive association between total insurance gross premium and economic growth in Nigeria. Based on the findings, the general conclusion is that insurance and economic growth in Nigeria have a considerable positive association. The study recommends that the National Insurance Commission should adopt policies that promote the growth and development of the insurance industry as a whole. Individuals and families should be educated on the importance of life insurance in order for it to have a substantial impact on Nigeria’s economic growth.
