Determination of Economic and Financial Factors Affecting Investment Instruments: An Application on Borsa İstanbul
Öz
This study aims to identify the economic and financial factors affecting investments in stocks, exchange
traded funds, and private-sector debt instruments. For this purpose, three different models are
developed based on the dependent and independent variables used in the study and the period range
of the study is determined as 2008:01 - 2023:07. The current study follows a time series analysis process
that takes structural breaks into account and conducts cointegration, causality, impulse-response and
variance decomposition analyses. According to the short-term findings, stock investments are affected
by inflation, interest rates, reserves, CDS, investor sentiment, risk appetite, and consumer loans; fund
investments are affected by inflation, interest rates, reserves, investor sentiment, risk appetite, and
consumer loans; and private sector debt instruments are affected by interest rates, reserves, risk
appetite, and consumer loans. In addition, according to the long-term findings, stock investments are
affected by all independent variables used in the study; fund investments are affected by inflation,
interest rates, reserves, investor sentiment, risk appetite, and consumer loans; and finally, private sector
debt instruments are affected by inflation, interest rates, reserves, risk appetite, and consumer loans.
