Turkey’s BIST 100 Surges 2.3% in a Day – Central Bank’s Stock-Buying Boost Sparks Wild Rally

Turkey’s benchmark stock index has exploded higher in a series of sharp rallies, with the BIST 100 surging 2.34% in a single session and opening with gains of over 100 points on multiple days, fueled by a radical new central bank policy that directly pumps money into stocks.

The BIST 100 index, which tracks the country's top 100 companies, jumped by approximately 316.4 points on Monday, closing with a gain of 2.34% [71758]. This followed a string of powerful openings: the index gained 104.5 points at the start of Tuesday’s trading [65693], rose 99.1 points on Wednesday [110976], and opened 40.2 points higher on another Tuesday [12090]. On the first trading day of 2026, the index surged 2.1%, or 236.86 points [40181].

The driving force behind these gains is a direct intervention by the Central Bank of the Republic of Turkey (CBRT). The bank announced a new funding strategy that provides cheaper financing to lenders who increase their purchases of domestic stocks [80220]. This policy, analysts say, is a clear shift toward using central bank tools to directly support the equity market, encouraging investment in local shares [80220].

Not all sessions have been positive. The index also saw a sharp drop of 20.7 points during a global sell-off [33252] and closed lower by 30.85 points on another Tuesday [12525]. However, the overall trend points to a market being aggressively propped up by state-backed incentives, as the BIST 100 also opened higher on multiple other occasions, gaining 20.8 points [21230], 55 points [8749], and 26.64 points [33768] in separate early sessions. The significant climb marks a volatile but upwardly biased period for investors in a key emerging market [128734].
