Abstract

Digital transformation can increase competitiveness and customer loyalty and become a business strategy, especially in the context of data security and trust. This study aims to empirically analyze the impact of digital transformation on customer loyalty, emphasizing the mediating role of customer trust at PT Pos Indonesia Pematangsiantar branch. Quantitative research using explanatory surveys of 100 customers selected by purposive sampling technique. The data collection instrument, with the distribution of questionnaires with a Likert scale of 5, has been tested for validity and reliability. Partial Least Squares-Structural Modeling based on SmartPLS 3. The results showed that digital transformation had a significant impact on customer loyalty trust (β = 0.836; p < 0.001) and loyalty (β = 0.906; p < 0.001). However, trust did not significantly impact loyalty (β = 0.076; p < 0.181). The study found that digital transformation can foster loyalty by providing a personalized, secure, and transparent service experience. This study's theoretical and practical implications are the strengthening of trust-based digital strategies for the postal services sector in developing countries

Abstract

This study investigates the strategic role of gold as a haven asset amid the anticipated 2025 global tax war, characterised by rising fiscal protectionism, currency volatility, and geopolitical fragmentation. Employing a qualitative literature review, the research synthesises scholarly findings, institutional data, and financial commentary to examine how gold performs under fiscal-driven crises. The findings reveal that gold remains a reliable hedge against inflation, exchange rate risk, and systemic policy shocks, supported by strong institutional trust and long-term investor demand. However, most prior studies focus on financial or monetary crises, leaving a significant gap in understanding gold's behaviour during state-led fiscal confrontations. This paper contributes by framing gold's relevance through a multi-dimensional lens, incorporating macroeconomic policy, digital investment behaviour, and central bank strategy. Further research is recommended to explore the impact of digital gold adoption in emerging markets and its implications for retail investor behaviour.
