The article examines the financial health of Bank Syariah Indonesia (BSI) through liquidity ratios—Cash Ratio, Financing to Deposit Ratio (FDR), and Liquidity Coverage Ratio (LCR)—during 2021-2023, a period marked by post-pandemic recovery and economic uncertainties. Drawing on literature from Brigham & Houston (2021), IFSB (2021), and OJK (2023), the study employs a quantitative descriptive methodology, analyzing BSI's financial reports to assess liquidity performance. Results reveal a stable Cash Ratio (20%-50%) an optimal FDR (73%-81%), and a high LCR (above 100%), demonstrating BSI's effective liquidity management and adherence to sharia principles. The findings highlight BSI's strong financial health but emphasize the need for proactive liquidity management to navigate future economic challenges.
