Zeynep Turan’s Analysis: The sharp profit dip at İş Bank is largely explained by the dramatic erosion of the net interest margin and the surge in swap costs. Strong fee‑based earnings confirm the bank’s pivot toward a service‑centric model, yet this alone cannot offset the margin pressure. Consumer loan and mortgage rate stresses will further tighten the credit‑deposit spread, raising the likelihood of stricter credit‑card limits and tougher new mortgage terms. Investors should monitor potential policy rate cuts by the central bank and any improvements in swap‑risk management as key catalysts for a margin recovery.
