This paper undertakes a critique of the quality of Singapore’s public economic data in the context of the claim that one of the island’s sovereign wealth funds, Temasek Holdings, reports that it has earned since inception in 1974 an average annualized rate of return of 16%. Over a similar time period the Singapore stock market earned 4.99% implying that Temasek on average outperformed the local stock market in which it was heavily invested, by a factor of more than three times every year. The paper replicates Temasek’s portfolio and analyses Singapore’s public finances and finds that irregularities may exist within Temasek financials. It concludes that if there are as of yet unknown financial weaknesses within Singaporean public finances that have yet to be realized then given the importance of the island in Asia’s financial markets, this should raise concerns over the quality of financial statements produced by government linked corporations and the public sector.
