31H26 BRSA CONSOLIDATED EARNINGS PRESENTATION Assuming continued fiscal discipline, a cautious CBRT stance, and a gradual normalization in energy prices in 2H26, we forecast year-end consumer inflation to be 30%. We expect the funding rate to gradually converge toward the policy rate by September. With limited room for policy rate cuts starting in 4Q26, the funding rate is expected to reach 36% by year-end. TURKISH ECONOMY (I/II) 5.0% 3.3% 3.6% 3.0% 2023 2024 2025 2026F We expect GDP growth to reach around 2.5% y/y in 1H26. Under our baseline scenario of gradually normalizing energy prices and a prudent policy mix, we maintain our 2026 GDP growth forecast at 3.0%.

We forecast the current account deficit to widen to 3.5% of GDP in 2026. Tourism revenues provide an important buffer during the summer months. CA DEFICIT / GDP (year end) -13bn$-42bn$ TURKISH ECONOMY (II/II) The cash deficit-to-GDP ratio stood at 2.6% in June, supported by resilient revenues and spending discipline. Despite softer activity, given the strong performance of 1H26, budget deficit is expected not to deviate much from the MTP target of 3.5% of GDP.
