The Treaty of Lausanne abolished the Capitulations without exception and the Republic was declared on 29 October 1923. Yet tariff autonomy waited until 1929, and the last instalment of the Ottoman public debt until 25 May 1954. Thirty-one years separate the two calendars.

Made in EU bargaining puts Türkiye's customs union to the test

Türkiye completed alignment with EU machinery rules on 27 October; the same day ACEA sought an exemption for European investments in Türkiye. Some 73.7% of automotive exports go to the EU, and Türkiye has no vote at the table writing the rule.

The Crete–Cyprus cable is blocked by contested seabed, not engineering

France's idea of postponing the Great Sea Interconnector made the headlines. The project was already slipping before the Libya vote. Some 40% of the survey work sits on seabed that Türkiye disputes, and Cyprus has tied its payment to a navigational warning.

Washington turns Kyiv's connectivity and Moscow's energy access into bargaining chips

Ahead of the mid-November round in Abu Dhabi, the US is pulling two levers at once. Kyiv's satellite link was throttled for 10 days, while Moscow saw the door open to diesel sales and an LNG swap. Ukraine is answering by striking missile feedstock in Siberia.

The Black Sea moratorium hinges on the refinery bargain, not Ankara

The Turkish-owned Azov Concorde sank off Bulgaria on 13 October, the third Turkish-owned loss in nine days. The moratorium text Ankara sent in September remains unsigned, because ship attacks are now part of the refinery–grid bargain brokered by Washington.

Europe's preference for home-built cars runs into Berlin's China sales

Macron wants EU support for electric vehicles tied to European production, and the Commission's proposal sets a 70% EU-content rule for public procurement. Volkswagen made 2.69 million of its 8.98 million deliveries in China in 2025, which is why Berlin fears retaliation.

Black Sea risk reaches NATO economic zones; small Turkish owners pay

On 5 and 6 October three Turkish-owned ships were hit in the economic zones of Romania and Bulgaria, and two sank. The 12-mile territorial waters that the insurance market carved out on 16 September are now the only safe lane, and Ankara's moratorium proposal has sat in Moscow for two months.

Probabilities

Scenarios

Scenario	Probability	Trigger	Market impact
H1The constraint holds, substitutes multiply	55%	External borrowing stays expensive, the 5-year credit premium settles above 280 basis points and rolling over through foreign funding gets dearer.	Policy weight shifts from price and interest tools towards regulation, incentives and selective credit allocation; the founding era's sequencing repeats with different instruments.
H2Rolling over gets easier	30%	Global yields retreat or the domestic fiscal framework is anchored in numbers; the risk premium narrows and access to external finance cheapens.	The constraint loosens, the incentive to build substitute instruments fades and policy returns to price tools.
H3Sharp squeeze	15%	An external shock or a jump in the energy bill erodes the reserve buffer quickly and the cost of rolling over moves up a step.	Spending composition narrows to compulsory items, investment is postponed and the constraint stops being a choice and becomes an imposition.

Module A

Constraints Matrix

STRUCTURAL AVG 3.7 · TACTICAL AVG 2.7Structural constraints dominate: the outcome is set more by these limits than by the actors' preferences.

Hard structural constraintspersistent · beyond the actors' will

Capacity to roll over external obligations · Türkiye
5/5
World Bank data put Türkiye's gross external debt stock at 514.99 billion dollars in 2024; what decides the outcome is not the amount but the cost of rolling it over.
The cost of borrowing · Türkiye
4/5
In the founding era the constraint was the tariff; today it is pricing. The 5-year credit premium and domestic yields together narrow the options for rolling over.
Institutional commitment framework · Türkiye
2/5
Türkiye joined the IMF on 11 March 1947, has concluded nineteen arrangements since and holds a quota of 4,658.6 million SDR; no programme is currently active.

The 107.5 million gold Ottoman lira assumed in 1928 was a debt the state had not contracted, and it occupied a budget line for thirty-one years.
Delay in the instrument months
3/5
Tariff autonomy could not be used until 1 October 1929; until the constraint lifted, policy ran on substitute instruments.

2/5
The central bank law passed on 11 June 1930, but the bank only opened for business on 3 October 1931; sixteen months sat between legislation and practice.

Signal vs Noise

SIGNAL 75% · NOISE 25%

NOISE
Independence was completed on 29 October 1923.
The commercial regime of the same treaty bound customs tariffs for five years, with the clock running from 6 August 1924; the tariff arrived on 1 October 1929. The last instalment of the Ottoman public debt was paid on 25 May 1954.
FRUS 1928, Vol. III — correspondence on the commercial regime with Türkiye
SIGNAL
The Capitulations were abolished in one stroke and without exception.
Article 28 of Lausanne states that the Capitulations are abolished in Türkiye fully and in every respect; judicial and fiscal privilege ended in law with that article.
BYU WWI Document Archive — Treaty of Lausanne, 1923
SIGNAL
While the constraint held, policy turned to substitute instruments.
The Cabotage Law, no. 815, was adopted on 19 April 1926 and took effect on 1 July 1926; the Law for the Encouragement of Industry, no. 1055, was enacted on 28 May 1927 with a fifteen-year term. Both produce protection without touching duties.

SIGNAL
New borrowing had started before the old debt closed.
The Republic's first foreign loan was 10 million dollars raised from the United States in 1930, while the last instalment of the Ottoman public debt fell on 25 May 1954. The relationship with external finance ran without a break.
