Expert Insight (Seda Çetin): The surge in tax revenues from banks and insurers mirrors improving profit margins and expanding balance‑sheet assets. Ziraat Bankası’s lead reflects a broadened state‑backed loan portfolio and effective net‑interest margin management. The surprising climb of savings‑finance firms signals heightened housing‑loan demand and a low‑rate environment creating profit opportunities. Market participants should monitor these entities’ cash flows and liquidity positions closely, as they will be pivotal for short‑term HFT strategies and swap market expectations on rate cuts.
