Türkiye's risk premium comes from within: CDS passes 250 as an 18.3-billion-dollar fund liquidation and a MASAK probe test the intermediation chain

According to Bloomberg HT, Türkiye's 5-year CDS exceeded 250 on 25 September for the first time since 27 May. The same week, the liquidation of 131 funds and an espionage probe into MASAK's data system show the premium is fed more by domestic intermediation and governance than by external shocks.

Why it matters

Our 25 September report read the main channel of pressure on Türkiye as the global floor rate and the dollar, and treated the CDS exceeding 250 as the threshold at which that channel turns into Türkiye-specific credit risk. The threshold was crossed a day later. According to Investing.com, the CDS rose from 223.02 on 11 September to 245.17 basis points on 24 September; the sharpest daily rise (+9.63 basis points) came on 21 September, before the days of weak US auctions. While the lira stayed flat at 48.93 on 25 September, foreign investors are pricing risk through the CDS.

Implications

  • Türkiye's 5-year CDS stood at 245.17 basis points on 24 September in Investing.com data; the crossing of 250 on 25 September appears only in Bloomberg HT, and Investing.com has no 25 September close. The two-week rise is 22.15 basis points.
  • The 131 funds belonging to 7 portfolio management companies that the CMB placed into liquidation cover about 18.3 billion dollars in assets and 455,758 investors; the liquidation period was extended from 3 to 6 months and there are 45 detainees. The sum equals about 33% of the 55.84 billion dollars in net reserves in the week of 18 September.
  • Türkiye's 10-year yield rose from 32.64% on 24 September to 35.61% on 25 September according to Investing.com and Trading Economics, and to 35.27% according to Bloomberg HT; the same day the 2-year yield fell from 37.09% to 36.86%. Whether the jump of about 300 basis points stems from a change of benchmark bond could not be verified.

What changed: the day the CDS accelerated does not match the global calendar

According to Bloomberg HT's market summary for 25 September, Türkiye's 5-year credit risk premium rose above the 250 level for the first time since 27 May. This information comes from a single source: in Investing.com's 5-year CDS historical data table, as of 26 September the latest value is 245.17 basis points for 24 September, and there is not yet a 25 September close. The exact closing value at which 250 was crossed therefore could not be verified; in this report the 250 threshold rests on Bloomberg HT and the numerical series on Investing.com.

Reading the series day by day underpins the report's main claim. According to Investing.com data, the CDS was 223.02 basis points on 11 September, 232.80 on 18 September, 242.43 on 21 September, 239.61 on 22 September, 240.86 on 23 September and 245.17 on 24 September. The largest single component of the two-week rise of 22.15 basis points is the jump of 9.63 basis points (+4.14%) on 21 September. That day came before the US Treasury's weak 5-year auction on 23 September and 7-year auction on 24 September, that is, before the most visible days of the global term-premium wave described in our 25 September report. Had the global channel alone been decisive, the sharpest rise would have been expected on 23–24 September.

In our 25 September report we judged the CDS rise of only 8 basis points from 18 to 23 September as limited and classified it as noise. The next day's data require that classification to be revisited: read together, the rise of 4.31 basis points on 24 September and the crossing of 250 reported by Bloomberg HT take the premium out of the zone that global rates can explain.

The fund crisis: an 18.3-billion-dollar lock in the intermediation chain

According to a Turkish Minute report of 25 September, the CMB placed 131 funds belonging to 7 portfolio management companies into liquidation. The funds' reported assets are about 18.3 billion dollars, and the number of affected retail investors is 455,758. The liquidation period was extended from 3 to 6 months; the liquidation of Tera funds is being handled by İş Bankası and the funds of the other 6 companies by the state lender Ziraat Bankası. According to the same report, the crisis was triggered by the failure of Pusula and Tera fund managers to meet redemption requests, the number of detainees rose to 45, and by 21 September MASAK had stopped attempted transactions worth about 51 million dollars.

The scale of the figures explains why the channel is domestic. By our own calculation, 18.3 billion dollars comes to an average of about 40,150 dollars per investor across 455,758 investors, and equals about 33% of the CBRT's net reserves, which fell to 55.84 billion dollars in the week of 18 September, and about 42% of net reserves excluding swaps of 43.1 billion dollars. These savings remain locked for at least 6 months during the liquidation. The problem is not an external price shock but the intermediation chain that carries domestic savings into assets: when a fund's redemption promise cannot be kept, investors question their trust in both the asset and the structure that holds it.

According to reports by Karar on 24 September and Turkish Minute on 25 September, President Erdoğan said the problem was confined to a limited area of the capital market and that there was no risk to the financial system. The first market test of this message is partly positive: according to Bloomberg HT, the BIST 100 closed on 25 September up 0.09% at 12,899 points. But according to Turkish Minute, the index had fallen more than 8% after the crisis; because the source does not state which date range this fall covers, it could not be verified.

MASAK and EMİS: a question of trust in the oversight infrastructure

A second domestic channel opened the same week. According to a Cumhuriyet report of 25 September, the Istanbul Chief Public Prosecutor's Office opened proceedings against 22 suspects on charges of political or military espionage over allegations that unauthorised queries were made in MASAK's Integrated Financial Intelligence System (EMİS) between 2012 and 2018; 5 people were detained and arrest warrants were issued for 16 people abroad. A technical review found that the protection mechanism for politically exposed persons (PEPs) had been disabled. The SDIF appointed trustees to AGMLAB and MRD, which developed the software. According to Turkish Minute, administrator access logs do not exist. Three former MASAK presidents will give statements on 28 September.

Its financial significance is independent of the probe's political dimension: MASAK is the institution examining the transactions of 117 executives in the fund crisis and the one that stopped 51 million dollars of transactions. The allegation that access logs do not exist in the institution's own data system boils down, for a credit investor looking from outside, to a single question: with what guarantee of data integrity are asset tracing and seizure operations in the fund crisis being conducted? The allegations have not been verified by a court; the suspects' defence has not been made public. Even so, what matters for pricing is not whether the allegation is true but how long the uncertainty lasts.

Bonds and the lira: the 300-basis-point jump could not be verified

According to Investing.com, Türkiye's 10-year yield rose from 32.64% on 24 September to 35.61% on 25 September; the day opened at 32.73% and closed at the high of 35.61%, with a low of 32.64%. Trading Economics also gives 35.61% for 25 September and a rise of 2.97 points on the previous session. Bloomberg HT's 10-year bond page, however, shows 35.27% for 25 September and a daily change of 0.00%. The two data sets contradict each other on both level and change.

Whether the jump was a genuine sell-off or a data break caused by the benchmark shifting to a new security could not be verified. The detail that deepens the doubt is the front end of the curve: according to Investing.com, the 2-year yield fell the same day from 37.09% to 36.86%. A 297-basis-point rise in the 10-year alongside a 23-basis-point fall in the 2-year on the same day would reduce the curve's inversion in a single day from about 445 basis points to about 125 basis points. A move of this scale could not be confirmed from a second primary source, such as a Treasury benchmark bond announcement; the report's thesis does not rest on this figure.

The currency side is quiet. According to Investing.com, the dollar/lira rate was 48.96 on 24 September and 48.93 on 25 September, down 0.07%; Bloomberg HT gives 48.97 and a 0.15% rise for the same day. Our 25 September report used a 24 September rate of 48.87 from another source; this 9-kuruş difference between sources may stem from differing closing times and could not be verified. The decisive point is this: according to Investing.com data, the CDS rose about 8% between 14 and 24 September, from 226.67 to 245.17, while the dollar/lira rate rose only about 0.6% between 14 and 25 September, from 48.62 to 48.93. With the currency managed through reserves, the CDS remains the most liquid instrument through which foreign investors can express risk.

The hidden link: not an external shock but a governance premium

Three data points point the same way. The CDS's sharpest day came before the global calendar; 18.3 billion dollars of savings are locked for 6 months; the data infrastructure of the institution overseeing the fund crisis is under investigation. This combination ties the premium not to external shocks such as the Fed or oil but to the credibility of domestic financial intermediation and oversight institutions. An external-shock premium unwinds when the shock passes; a governance premium unwinds only with institutional proof, that is, liquidation payments made on schedule and a probe that answers the question of data integrity.

The practical consequence of this distinction is the time horizon. The global channel in our 25 September report was tied to the 28 October FOMC meeting or to US auction demand and could reverse within weeks. The domestic channel, by contrast, is tied to the 6-month liquidation timetable and to statements starting on 28 September; the part of the CDS that has risen because of this channel should not be expected to fall back along with global relief. CBRT weekly securities data on the direction of foreign portfolio flows this week were not reviewed tonight; whether foreign investors exited bonds and equities could not be verified.

Second-order effects

And then what?

Starting point

About 18.3 billion dollars in assets of 131 funds and 455,758 investors are locked in liquidation for at least 6 months; in the same week the data system of MASAK, which monitors the fund crisis, came under investigation and Türkiye's CDS exceeded 250 according to Bloomberg HT.

  1. 1

    Fund flows and saving preferenceswithin days

    Holders of the locked savings and other fund investors prioritise liquidity and shift from portfolio funds into deposits or foreign currency; redemption requests rise at funds with similar structures.

    Watch: TEFAS weekly fund size data and CMB announcements of further fund liquidations or redemption deferrals

  2. 2

    Domestic debt marketwithin weeks

    Redemption pressure turns into fund sales of equities and private-sector debt instruments; demand weakens for domestic bond and bill issuance by banks and companies, and spreads widen.

    Watch: The spread of private-sector bill issuance rates over Treasury bills and the BIST 100's position relative to its 24 September close of 12,888 points

  3. 3

    External financing costwithin months

    Tighter domestic financing conditions and governance uncertainty keep the premium foreign investors demand for Türkiye credit risk high; the Treasury's and banks' cost of rolling over external debt stays high even if global rates fall.

    Watch: Whether Türkiye's 5-year CDS stays above 250 basis points and the yield on the Treasury's next eurobond issue

What breaks the chain

Liquidation payments started ahead of schedule by İş Bankası and Ziraat Bankası, no redemption restrictions emerging at other funds, and an official assurance on MASAK data integrity after the 28 September statements would break the chain at the first step.
