The role of investor trust in mediating the impact of perceived blockchain integration on perceived stock market efficiency: evidence from the amman stock exchange

Abstract

This study examines the mediating role of investor trust in the relationship between perceived blockchain integration and perceived stock market efficiency within the Amman Stock Exchange (ASE). The Amman Stock Exchange (ASE), established in 1999, is the sole securities exchange in Jordan and one of the leading emerging markets in the Middle East and North Africa (MENA) region. Drawing on technology acceptance theory, trust theory, and market efficiency theory, the research develops and tests a dual-pathway model wherein perceived blockchain integration relates to perceived market efficiency both directly and indirectly through investor trust. Using structural equation modeling with data collected from 400 market participants, the findings reveal that perceived blockchain integration is significantly and positively associated with investor trust (β = 0.849, p < 0.001) and with perceived stock market efficiency (β = 0.448, p < 0.001). Importantly, investor trust partially mediates this relationship (β = 0.380, p < 0.001), confirming the dual-pathway impact. Among blockchain dimensions, security demonstrates the strongest effect on both investor trust and market efficiency. The study contributes to the emerging literature on blockchain in financial markets by empirically validating the psychological mechanisms through which technological innovations translate into more favorable perceptions of market functioning. For market regulators and exchange administrators, the findings suggest that comprehensive blockchain implementation strategies should address both technological deployment and trust-building initiatives to strengthen favorable investor perceptions of market efficiency in emerging markets.
