Savings is essential for boosting economic growth. Low savings in a country will have negative consequences for both investment and economic growth. South Africa has continued to expe rience declining saving rates and in recent years, accompanied by declining economic growth. The study evaluated savings in South Africa by decomposing it into household saving, cor porate saving and public saving. The focus was to investigate the determinants of household savings, corporate and public savings. In addition to examining the determinants of savings, the research has also analysed the saving-investment relationship for South Africa. The study used a Bayesian vector auto regressive model to investigate the determinants of household sav ing from 1980Q1 to 2017Q4. The results of the investigation on household saving showed that GDP, inﬂation rate, and ﬁnancial deepening determine household saving in South Africa. The Bayesian VAR was also used to identify the determinant of budget deﬁcit between 1980Q1 to 2017Q and found Real GDP, inﬂation rate, total government debt, investment by general government and the inﬂation rate to be determinants. The Blundel-Bond Generalized Method of Moment (GMM) was used to investigate the determinants of corporate saving in form of cash holding for 80 non-ﬁnancial ﬁrms listed on the JSE between 2007 and 2017. The results showed leverage, cash ﬂow, debt maturity and previous amounts of cash holding to have signiﬁcant eﬀect on cash holding in SA. Lastly, the study examined the saving-investment nexus for South Africa using yearly data from 1980 to 2016. Using the Autoregressive Distributed lag (ARDL) and the Error Correction Model, (ECM), the study found a cointegrating relationship between domestic saving and domestic investment. It further found a positive relationship between domestic saving and domestic investment in both the short and long run. Causality analysis showed a unidirectional causality from domestic saving to domestic investment.
