Tóm tắt:
Nghiên cứu này xem xét mối quan hệ giữa tích trữ thanh khoản (TTTK) và khả năng sinh lợi (KNSL) của ngân hàng, đồng thời là một trong những nghiên cứu đầu tiên phân tích sự thay đổi của liên kết này trong giai đoạn đại dịch Covid-19. Dữ liệu được sử dụng từ 33 ngân hàng thương mại tại Việt Nam trong giai đoạn 2012–2023 để thực hiện các ước lượng bằng phương pháp moment tổng quát (GMM) hệ thống hai bước trên mô hình bảng động. Kết quả nghiên cứu cho thấy tồn tại mối quan hệ nghịch biến giữa TTTK và KNSL của ngân hàng. Điều đó hàm ý rằng việc nắm giữ quá nhiều tài sản thanh khoản có thể khiến ngân hàng giảm KNSL. Trong giai đoạn đại dịch Covid-19, mối liên kết giữa TTTK và KNSL của ngân hàng có xu hướng suy yếu. Điều này hàm ý rằng ngân hàng giảm KNSL ở mức độ ít hơn khi TTTK nhiều hơn vào giai đoạn này. Các kết quả nghiên cứu góp phần làm sáng tỏ tầm quan trọng của việc quản lý TTTK hợp lý nhằm xây dựng một số biện pháp phòng ngừa để bảo vệ ngân hàng trong những cuộc khủng hoảng, chẳng hạn như đại dịch Covid-19.

Abstract:
This study examines the relationship between liquidity hoarding and bank profitability and is among the first to analyze how this relationship evolved during the Covid-19 pandemic. The study utilizes data from 33 commercial banks in Vietnam over the period 2012–2023 and employs two-step system GMM estimation on a dynamic panel model. The findings indicate an inverse relationship between liquidity hoarding and bank profitability, implying that excessive holdings of liquid assets may reduce bank profitability. During the Covid-19 pandemic, the link between liquidity hoarding and bank profitability weakened, suggesting that banks experienced a less pronounced decline in profitability when accumulating more liquidity during this period. These findings highlight the importance of prudent liquidity hoarding management in designing preventive measures to safeguard banks during crises, such as the Covid-19 pandemic.
