Kerem Tufan – Director of Commercial Loans and Central Bank Policies: The buyback surge provides a short‑term liquidity boost while fortifying corporate capital structures. With stable interest rates and constrained credit expansion, big‑cap buybacks become a crucial tool for market equilibrium. Continuation of this trend should dampen BIST volatility and reshape investor risk perception positively.
