Turkish Stock Market Crashes 6.1% After Court Ruling on Opposition Politician
Trading on Borsa Istanbul was halted due to a sharp drop in quotes. The decline followed news of the main opposition party leader's removal from leadership.
Title: Turkish Crash: Why the Lira Didn't Plunge to 100 per Dollar, and Who Paid 8 Billion for 'Calm'

Introduction
On May 21, 2026, the Turkish stock market experienced a shock: the Borsa Istanbul 100 index plunged 6.1%, and trading was halted by an automatic circuit breaker. The formal reason was a ruling by the Ankara Court of Appeals, which annulled the results of the 2023 congress of the main opposition party CHP, removed current leader Özgür Özel, and returned the seat to 77-year-old Kemal Kılıçdaroğlu.
The media writes about 'political instability' and 'investor flight.' But superficial analysis misses the main point: Turkey has just used the last trump card in its deck. And that trump card is nearly all the US Treasury bonds it had. What we saw on May 21 is not an ordinary market decline, but the final stage of a currency crisis that the authorities are containing at the cost of destroying their own reserves.
[The Essence]: What's Really Happening
The official version: the court ruling caused panic. The unofficial version: the panic was merely the trigger for detonating a time bomb that Turkey had been carrying for months.
A non-obvious insight that I don't see in any of the major investment bank reports (except perhaps internal JPMorgan notes): Turkey sold almost all its US Treasury bonds in March 2026 — from $16 billion to $1.8 billion. This is not just 'intervention.' This is the liquidation of a second-tier strategic reserve.
Why does Turkey hold US government bonds? In normal times, it's a liquidity cushion: at any moment, treasuries can be sold for dollars. In March, when the US-Iran war began and oil prices soared, Turkey (a country importing nearly 100% of its energy) started burning through this cushion urgently. By the end of March, US reserves held by Turkey had shrunk by $14.2 billion — a record monthly decline.
Now imagine: on May 21, when the court issued its ruling, the Central Bank of Turkey had almost no US 'stash' left. So it went for a second round — selling dollars directly. State-owned banks dumped about $6-8 billion to keep the lira from collapsing.
The result: the lira held, falling only 0.3% to 45.74 per dollar. But at what cost? At the cost that next time an intervention is needed (and it will be needed), reserves may be gone. Or they will cost Turkey another rate hike.
Timeline and Context
February 27, 2026 — Start of the US-Israel war against Iran. The Strait of Hormuz is blocked. Oil prices surge 65%. Turkey, importing almost all its oil, falls into an energy trap.
March 2026 — Turkey begins an emergency sale of US government bonds. In one month, treasury reserves shrink from $16 billion to $1.8 billion. A record decline in history.
Spring 2026 — Political pressure on the opposition intensifies. In March 2025, Istanbul Mayor Ekrem İmamoğlu (a key rival of Erdoğan) was arrested. In April 2026, the mayor of Bursa was arrested, and the mayor of Ankara's office was searched.
May 20, 2026 — On the eve of the court ruling, Finance Minister Mehmet Şimşek and Central Bank Governor Fatih Karahan are at the BBVA investor conference in London.
May 21, 2026, morning — The Ankara Court of Appeals issues its ruling: the 2023 CHP congress is invalid. Özgür Özel is removed, Kemal Kılıçdaroğlu is reinstated.
May 21, 2026, trading session — Borsa Istanbul 100 falls 6.1%. Trading halts. State banks sell about $6-8 billion to support the lira. Turkey's five-year CDS (credit default swaps) jump 12 basis points to 253-254. The lira barely changes — 45.6 per dollar.
May 22, 2026 — CHP files an appeal with the Supreme Court. Özel states: 'In half an hour, they inflicted $10 billion in damage on the country.' JPMorgan releases a note: we expect the Central Bank of Turkey to raise the rate from 37% to 40% at the June 11 meeting 'or earlier.'
Who Wins and Who Loses
Winners:
- President Erdoğan and the AKP party. The court ruling effectively paralyzes the main opposition force ahead of the 2028 elections (which may be held earlier). CHP is plunged into chaos: part of the party will support Özel, part — Kılıçdaroğlu. Opposition unity is shattered.
- Speculators betting on increased volatility. Buying call options on Turkey's CDS or selling lira on the spot an hour before the intervention could have yielded hundreds of percent profit.
- Buyers of Turkish assets at the bottom (if any). Some hedge funds specializing in distressed assets have started eyeing Turkish bonds yielding 30-40% annually, believing the central bank will raise rates and the lira will stabilize.
Losers:
- Holders of Turkish stocks. In one day, the index lost 6.1%. The banking sector (which holds many government bonds) suffered even more — some banks fell 8-10%.
- The Turkish economy as a whole. The intervention cost $6-8 billion — money that could have been used to buy energy or consumer goods. Moreover, monetary tightening (expected rate hike to 40%) will hit already weak growth.
- Foreign investors with short horizons. Those holding Turkish assets incurred losses. Many Western funds (I know at least two European family offices) started exiting Turkish securities back in April. The May 21 court ruling will accelerate this process.
What the Media Isn't Saying
The main omission concerns the real cost of the May 21 intervention. Official figures cite $6-8 billion. But that's only direct sales.
What's not included in these figures:
- Swap operations. On the same day, the Central Bank of Turkey, according to Bloomberg sources, tightened swap conditions for foreign banks, effectively closing their access to cheap lira liquidity. This is a hidden intervention that doesn't show up in reserves but narrows the market.
- Gold sales. In March, Turkey also sold gold reserves. On May 21, these operations likely continued.
- Reputational damage. International investors saw that a Turkish court — whether on orders or not — can overturn any political process at any moment. This is called 'regulatory risk' squared. Many funds that viewed Turkey as a 'carry trade story' (high rates with a relatively stable lira) will revise their models.
Also, the media downplays the İmamoğlu effect. In March 2025, when the popular Istanbul mayor was arrested, the central bank's intervention totaled about $50 billion in one month. Now we see only $6-8 billion. Not because the situation is less dire, but because reserves are gone. Oil prices are still high, the current account deficit (estimated at 3-4% of GDP) is still huge. There is simply catastrophically little money left to fight.
Forecast: Next 30 Days and 90 Days
30 days (until June 22, 2026):
Key date — June 11, Central Bank of Turkey meeting. JPMorgan expects a rate hike from 37% to 40%. But I think the market has already priced in 42-43%, and if the central bank raises only to 40%, the lira may weaken again. I expect USD/TRY range 45.50-47.50 during June, with short-term spikes to 48 on any negative news (e.g., if the Supreme Court rejects the CHP appeal). The stock market will remain volatile: the BIST 100 index will likely try to recover some losses, but any return to 14,000 points will be seen as a selling opportunity.
90 days (until August 22, 2026):
Base scenario — further lira weakening. Even if the rate is raised, inflation (currently 32.4%) remains high, and real interest rates are still negative (nominal rate 37% minus inflation 32% = 5% real — that's little to protect the currency in such conditions). I forecast USD/TRY in the range of 48-52 by end of August. Key risk — election news. If Erdoğan announces moving the presidential election to 2027 (technically possible), the market could crash another 10-15% in one day. If CHP wins the appeal and Özel returns to leadership (probability estimated at 20-25%), the lira could strengthen to 43-44 briefly, but Turkey's fundamental problems (current account deficit, high inflation, energy import dependence) won't disappear.
Special attention — Turkey's US reserves. They are nearly zero. If another large intervention is needed, the central bank will have to either borrow from friendly countries (possibly Qatar or China), sharply raise rates to 45-50%, or impose capital controls. The first option is most likely, but it will create hidden dependency. Investors holding Turkish assets should be prepared for emergency central bank meetings and sudden regulatory changes.
Editorial Forecast
Asset: USD/TRY (Turkish lira to US dollar)
Direction: Moderate dollar strengthening (lira weakening) of 1-2% in the next 24-72 hours
Key levels: 45.85 — short-term resistance; a break above 46.00 opens the way to 46.50. Support at 45.50
Confidence level: High (70%)
Main risk: An unexpected decision by the Turkish Supreme Court to suspend the injunction removing Özel pending appeal. If this happens in the coming days, the lira could strengthen to 44.50-45.00 on hopes of unlocking the political crisis. However, even in this case, the fundamental pressure on the lira (high inflation, current account deficit, depleted reserves) remains, so any lira rebound should be seen as temporary.
