Increases in oil prices cause inflation. Interest rates are expected to decrease as a result of the expansionary monetary policies of the central banks in response to the indirect effect of increasing oil prices on inflation. Because an increase in oil price creates an additional foreign currency inflow to Kazakhstan, this leads to the appreciation of its national currency tenge. Therefore, this study uses monthly Brent Oil Price (OP), Consumer Price Index (CPI), and Real Effective Exchange Rate (REER) values for the period 2015:M1–2021:M11 to investigate the effect of oil price on inflation and real exchange rate in Kazakhstan. Analysis are performed using the Structural Vector Autoregression (SVAR) model. The results showed that while the Real Effective Exchange Rate mostly affects the Oil Price, the Consumer Price Index variable affects the Real Effective Exchange Rate.

In this study, the relationship between KASE stock market closing prices and oil prices is analyzed using ADF and Zivot-Andrews' (1992) unit root tests and monthly data for the period of 2016-2021. First, the variables are tested for causality. Results show that there is a causal relationship between the real exchange rate and closing prices and between oil prices and the real exchange rate. The short-term effects of the variables are investigated using the VAR method. Results show that Brent crude oil prices have a positive effect on KASE closing prices, while the real exchange rate has a negative effect. In conclusion, changes in oil prices affect the formation of stock prices.

The study examines the effect of Brent oil prices on the regional real per capita income in Kazakhstan by a panel data analysis of sixteen states and a quarterly time series between the years of 2008 and 2015. The long-term relationship between the series was examined with the help of Westerlund (2007) cointegration test. In this context, a positive and significant relationship was found between long-term oil price changes and per capita regional real income growth. In addition, causal relations between variables were investigated by Dumitrescu and Hurlin (2012) using panel Granger causality test. Empirical findings from both the co-integration and the Granger causality test show that the increase in oil prices has an important positive effect on the real income of the Kazakhstan regions.
