Who Owns the Trading Volume Crown on BIST? Top Active Brokerage Firms Revealed

At 15:30, the brokerage firms with the highest trading volume on Borsa Istanbul continue to shape market liquidity.

Liquidity Leaders: Who Holds the Volume Crown?

■Garanti Yatırım: 22% of total trading volume, breaking the record for consecutive first‑place finishes.

■İş Yatırım: 18% share, second place, with aggressive trading in technology stocks.

■Akbank Yatırım: 15% share, third place, notable for heavy activity in fixed‑income securities.

■QNB Finansinvest: 12% share, fourth, buoyed by an influx of foreign‑sourced investors.

■Deniz Yatırım: 9% share, fifth, increasing turnover in small‑ and mid‑cap equities.

Trading Volume and Market Depth Implications

■Total turnover reached ₺4.3 billion today, a 3% rise over the previous session.

■Average spread narrowed to 0.04%, indicating improved liquidity.

■Short‑term volatility remained low at 1.2%, suggesting that active brokerages are stabilizing the market.

The bulk of market liquidity is supplied by these five brokerages. Garanti Yatırım and İş Yatırım, together holding roughly 40% of the volume, help keep the equity market resilient amid tightening commercial credit and rising corporate financing costs. Meanwhile, the rising shares of QNB Finansinvest and Deniz Yatırım signal a diversification of investor profiles and foreign capital inflows. As SME credit tightens and the growth rate of commercial loans slows, investors may shift toward more liquid, low‑spread transactions. This trend points to limited volatility on Borsa Istanbul in the upcoming quarter, with institutional investors still steering the market.
