The dynamic relationship between economic crisis, macroeconomic variables and stock prices in Sri Lanka

Abstract

PurposeThis study aims to examine the short- and long-term equilibrium relationship between All share price index (ASPI), macroeconomic variables and the economic crisis in Sri Lanka.Design/methodology/approachMonthly time series data for inflation (CPI), industrial production (IP), an exchange rate (EX), an interest rate (TB), short-term interest rate (CD) and economic crisis were used from 2010 to 2021. The ADF test, the bound testing approach, the CUSUM test and the CUSUMQ test were used in this study.FindingsThe findings show a long-run stable relationship between stock price, macroeconomic variables and political crisis (i.e., CPI, IP, ER, TB, CD and economic crisis). The results of the Johansen cointegration test suggest that there is at least one cointegrating equation, indicating that there is a long-run equilibrium relationship between macroeconomic variables and stock prices in Sri Lanka.Research limitations/implicationsThe vector error correction estimates show that the coefficient of the error correction term is significant with a negative sign, indicating that a long-run dynamic relationship exists between macroeconomic variables and stock prices. In the short term, economic crisis has had a big effect on stock prices suggesting that Sri Lanka’s domestic financial markets are linked to the stability of the country.Originality/valueThis research establishes the links between stock returns, macroeconomic variables and economic crisis. So far, research has been unable to establish the empirical nature of such links. The authors believe that this paper fills that gap.

The Influence of Fiscal, Monetary, and Public Policies on Sustainable Development in Sri Lanka

“…Data from 1990 to 2021 in the Sri Lankan context have found that increasing inflation in the short and long term hurts economic growth. The availability of money has a positive impact in the short run but an adverse impact on the economic growth rate (Madurapperuma, 2023) [36].…”

Financial Performance and Share Price: Evidence from Manufacturing Firms Before and During the Covid-19 Pandemic

“…Signaling theory explains why corporations provide statistics in the form of monetary reviews to external parties (Madurapperuma, 2022). The document provision was due to information asymmetry between internal and external corporate parties (Mamun & Chowdhury, 2022).…”

“…In looking on the contemporary ratio, the analysis have to also bear in mind the agency's situations and surroundings, including control plans, the industrial zone, and wellknown macroeconomic conditions (Madurapperuma, 2022). The existence of an destructive effect between the modern ratio on stock price is strengthened by Aggarwal's research (2022), which states that the cutting-edge ratio has a great impact on business enterprise inventory charges with a poor relationship.…”

“…It has a bad influence due to numerous elements posed by means of the agency, particularly the company's overall performance which isn't always simplest healthy independently but additionally for the future it should have reasonable possibilities (Salina et al, 2021). In the meantime, risky enterprise prospects result from risky economic conditions (Madurapperuma, 2022). Similarly, the modern-day ratio has obstacles in which the present day ratio is a static or constant degree that measures the sources to be had at a particular time to fulfill current obligations (Mbona & Yusheng, 2019).…”

Macroeconomic Factors and Jakarta Stock Exchange: A Comparative Analysis Pre- and Until the COVID-19 Pandemic

“…There is a lack of definitive criteria regarding which macroeconomic variables can impact the stock price index and whether the stock price index, in turn, affects these variables. Additionally, the implications of the COVID-19 pandemic on the global economy and financial crisis remain uncertain, making it unclear how these factors will influence the stock market (Madurapperuma, 2022). The purpose of this article is to clarify some of the important issues brought up, such as whether there is a long-term equilibrium link between the Jakarta Composite Index and factors like interest rates (BI Rate), inflation, exchange rates, and global oil prices.…”
