Turkey’s Central Bank Faces Crisis: A Record $12 Billion Intervention in Currency Defense
In a dramatic economic response, Turkey’s central bank depleted nearly $12 billion in an unprecedented intervention to stabilize the lira after a political upheaval associated with President Recep Tayyip Erdoğan’s detention of prominent opposition figure, Ekrem İmamoğlu. This incident has raised significant alarm among investors, resulting in a stark fall in the value of the currency.
Massive Currency Reserves Deployed
On Wednesday, the central bank’s expenditure reached $11.5 billion in a bid to prop up the lira, a transaction identified as the largest recorded intervention to date. Following İmamoğlu’s arrest, the lira plummeted by as much as 11 percent against the US dollar, marking an all-time low and provoking widespread market fears.
A Turkish banker remarked that officials seemed to have “lost control” of the market early on Wednesday, leading to a significant erosion of investor confidence.
Market Reactions and Assessments
Prominent financial institutions like JPMorgan Chase report that liquidity for the lira was compromised due to large capital outflows experienced on the same day. The central bank declined to comment on these events, but analysts speculate that more interventions likely persisted into the latter part of the week.
In addition to these currency interventions, policymakers convened an emergency central bank meeting on Thursday, where a key overnight interest rate was raised to encourage local savers to retain their assets in lira rather than convert them to dollars.
Impact on Financial Markets
Although these actions helped mitigate further declines, the lira ultimately ended the week down 3 percent. Notably, Istanbul’s Bist 100 share index suffered a significant drop of nearly 8 percent—its steepest weekly decline since 2008.

Political Context and Future Uncertainties
İmamoğlu, the mayor of Istanbul and a significant figure in Turkey’s political opposition, was seen as a serious contender for the presidency representing the Republican People’s Party (CHP). His detention has instigated days of civil unrest, with calls for more protests over the weekend. Erdoğan has characterized these demonstrations as “street terrorism.”
This week’s political escalations present a formidable challenge to the economic reform agenda initiated after Erdoğan’s re-election in 2023, a plan intended to stabilize Turkey’s enduring inflation crisis and restore investor confidence.
Led by Mehmet Şimşek, a former banker with Merrill Lynch, efforts included substantial interest rate hikes—reversing former policies of keeping rates low in the face of high inflation—and increased taxation. While these measures have lowered inflation significantly, from over 85 percent in late 2022 to 39 percent, broader investor sentiment remains cautious.
The Road Ahead for Investors
Long-term investors express skepticism about Turkish assets due to fears that Erdoğan may revert to unorthodox policies previously abandoned. Nonetheless, hedge funds have engaged in “carry trades,” with approximately $35 billion being funneled into higher-yielding investments, capitalizing on interest rates exceeding 40 percent, according to JPMorgan.
As Turkey navigates this tumultuous political climate and its economic repercussions, the central bank’s actions in the coming weeks will be critical in shaping market confidence and stability.
