Pension funds are in charge of the decisions concerning the allocation of a very large share of the wealth of most countries. To guarantee financial viability, the funds should be invested in agreement with the general principles of safety, yield, liquidity and social economic utility. In this article, we evaluate the performance and the long-term viability of the public pension scheme fund managed by Rwanda Social Security Board, the major Rwandan pension fund, by using financial information covering the period from 2009 until 2014. The findings cast doubt on the long-run financial viability of the fund, and suggest the opportunity to implement more sound investment strategies, and possibly also to commit to more realistic payment plans.
