Turkey’s benchmark stock index slipped in the first half of trading as investors positioned for a likely interest-rate cut from the central bank, while a mixed global backdrop and lingering concerns about funding for artificial intelligence spending kept risk appetite in check.
Turkey BIST 100 Falls Before Central Bank Rate Decision

The BIST 100 was down 0.35% at 11,537.15 points by 1 p.m., after shedding 39.96 points on turnover of 33.4 billion lira. That may look modest, but the move matters because the market is trading on expectations, not just earnings. When the main catalyst is monetary policy, the index becomes a referendum on whether cheaper money will support growth without reigniting inflation pressure.
Banks edged up 0.12%, suggesting investors still see value in lenders if the policy easing cycle continues. But holding stocks fell 0.84%, and financial leasing and factoring plunged 5.57%, showing how quickly sentiment can turn against credit-sensitive names when rate expectations shift. Transportation was the day’s strongest sector, up 0.61%, underscoring the hunt for pockets of domestic cyclicality even in a cautious tape.
The key macro driver is Thursday’s central bank decision. Economists in an AA Finans poll expect the Central Bank of the Republic of Turkey to cut the policy rate by 100 basis points to 36%. That would reinforce the market’s view that the easing cycle is still alive, but it also raises the stakes for banks, lenders and rate-sensitive sectors that will live with the consequences of a cheaper funding environment.
Globally, the mood was also less supportive than it has been for much of the year. US megacap earnings have sent mixed signals, and investors remain uneasy about how artificial intelligence capital spending will be financed. That matters far beyond Wall Street: when the AI trade wobbles, it tends to hit global risk sentiment, and emerging-market equities rarely escape unscathed.
For investors, the setup argues for selectivity, not blanket caution. The best relative opportunity is likely in domestic winners that can benefit from easier financial conditions without depending on fragile external demand. Banks could remain a key barometer of whether rate cuts are being priced as growth support or as a warning sign on inflation and margins. Leasing and factoring names, by contrast, look vulnerable if financing conditions stay volatile.
The next catalyst is the rate decision itself, followed by weekly money and banking data. If the central bank delivers as expected and signals room for more easing, the BIST 100 could regain traction toward the 11,700-11,800 resistance zone. If it disappoints, the 11,400 and 11,300 support levels will quickly come into focus. For now, the market is telling us that Turkey is still a macro story first and a stock-picking market second.
