Türkiye's fund crisis reaches the banks as the energy bill climbs

On 30 September the BDDK handed management of 3 investment banks to the TMSF, and the BIST 100 fell 21% below its May peak. The fuel sliding-scale system ended on 1 October; in August the energy bill had risen 33.8% to 6.464 billion $.

Why it matters

On 30 September the fund crisis reached a banking licence for the first time, though the 3 banks hold just 0.22% of sector assets. Equities read it as systemic: the BIST 100 fell about 5% in two sessions to 11,947.18, 21% below its May peak. Sovereign pricing is calm, with the 10-year yield at 32.84% (30 Sep) and CDS at 248.74 bp (29 Sep). The real burden comes over the next 3 months, as the petrol tax rises monthly and an energy bill of 6.464 billion $ in August keeps currency demand alive. Both shocks land on one buffer: the CBRT's room on rates and reserves.

Implications

  • On 30 September the BDDK transferred the management of Tera, Destek and Hedef investment banks and 2 factoring companies to the TMSF; the banks' share of sector assets is 0.22%, the factoring firms' 1.45%.
  • The BIST 100 fell to 11,947.18 on 30 September, about 21% below its May peak of 15,204.92; its loss for September was 16.65%.
  • The special consumption tax on petrol will be 7.90 TL in October, 11.36 TL in November and 14.8277 TL in December; the August trade deficit widened 22.3% to 5.239 billion $.

The crisis reaches a licensed bank

One day after the Fund Coordination Board was set up on 29 September, the state went a step further. According to AA, on 30 September Türkiye's banking regulator, the BDDK, transferred the management of Tera, Destek and Hedef investment banks and 2 factoring companies to the TMSF, the Savings Deposit Insurance Fund. The shareholder rights attached to a 95% stake in Tera Yatırım Bankası now sit with the TMSF.

The institutions carry little weight. The 3 banks make up 0.22% of sector assets, and the 2 factoring firms 1.45% of factoring assets. According to Bloomberg HT, owners of the factoring shares were given 6 months to transfer them to qualified buyers. Turkish Minute reported that prosecutors issued detention orders for 34 more suspects the same day.

Our previous report highlighted the divergence on 29 September, when the factoring index fell 8.20% while the banking index rose 0.10%. The 30 September decision formally ended that separation. Although the balance-sheet impact is narrow, this is no longer a capital-markets case about 131 funds. It is now an intermediation case that also covers 3 banking licences.

Equities read it as systemic, bonds did not

According to AA, the BIST 100 lost 343.40 points on 30 September and touched an intraday low of 11,926.04. Only 13 indices rose while 86 fell, so the selling did not discriminate between sectors. CNBC-e reported that the index had also fallen 2.40% the day before, taking the two-session loss to about 5%.

Trading Economics data show the index peaked at 15,204.92 in May. The close of 11,947.18 is about 21% below that peak; a bear market is the term used for a fall of 20% or more from a peak. The loss in September was 16.65%.

The sovereign debt market shows no such panic. According to Investing.com, the 10-year yield eased from 32.92% on 28 September to 32.84% on 30 September. Five-year CDS, the annual cost of insuring Türkiye's dollar debt against default, slipped from 249.98 on 28 September to 248.74 basis points on 29 September. According to AA, the dollar closed at 49.0175 lira on 30 September.

This gap shows that, for now, markets treat the crisis as a problem for household and brokerage balance sheets. The money of 455,758 investors is tied up in liquidation, but the state's capacity to meet external payments is not being questioned. The gap would close if domestic losses turned into demand for foreign currency. That shift is not yet visible in a lira at 49.0175 or in CDS at 248.74 basis points.

The tax goes to the pump, the bill to the reserves

The second burden arrived the same week. According to Hürriyet, the sliding-scale system, which absorbed part of fuel price rises through cuts in the special consumption tax, ended on 1 October. Restoring the tax in one go would have meant a rise of about 12.47 TL per litre of petrol. The decision spreads this over 3 months: the tax on petrol will be 7.90 TL in October, 11.36 TL in November and 14.8277 TL in December.

This adds a new tax-driven step to inflation in each of October, November and December. In Bloomberg HT's survey of 19 institutions, the median expectation for September is 2.20% month on month and 30.30% year on year. TurkStat will publish the data on 3 October; the tax steps will not affect that release but will enter prices from the October data onwards.

On the external side, the energy bill is growing. According to AA, energy imports rose from about 4.83 billion $ to 6.464 billion $ in August, an increase of 33.8%. Crude oil imports fell 1.1% in volume, so the increase came from price, not volume. According to Anka, the August trade deficit widened 22.3% to 5.239 billion $.

Excluding energy and non-monetary gold, the deficit is only 1.088 billion $. In other words, most of the gap comes from imported energy and gold. According to AA, Brent futures closed at 98.90 $ on 30 September; as long as the price stays around 100 $, this item will not shrink.

Two shocks, one buffer

The fund crisis and the energy shock come in through different doors but meet in the same place. Data cited by CNN Türk show gross reserves fell to 174.4 billion $ in the week of 18 September. Fund losses are eroding households' lira assets, while the energy bill creates fresh demand for foreign currency every month.

In this situation the CBRT is squeezed from 2 directions. If the tax steps push inflation up for 3 months, rate cuts are delayed. If lost confidence pushes savings into foreign currency, reserves are spent. Our previous report noted that the 2-year yield, at 37.03%, sits above the policy rate; markets already doubt a cut is coming.

One more detail fits the same picture. According to a compilation by Memurlar.net, the data protection authority KVKK announced 9 data breaches on 30 September. One of them, at Papara Menkul Değerler, came through phishing that targeted Okta. Customer names, investment profiles and tax status were affected; the number of people was not disclosed. While 455,758 investors wait for payment, such data could be used for fake payment offers.

What to watch

Four indicators stand out for the next 3 weeks. First, whether any new transfer to the TMSF follows the first 5 institutions. Second, whether the 3 October CPI print exceeds the median expectation of 2.20%. Third, whether CDS settles above 250 basis points. Fourth, whether the energy bill stays above 6 billion $ in the September trade data.

As long as the gap between equity and sovereign pricing stays open, this remains a crisis of confidence. If CDS and the currency close that gap, the energy shock and domestic loss of confidence will start draining the same reserves.

Second-order effects

And then what?

Starting point

On 30 September the fund crisis reached banking licences as 3 investment banks were transferred to the TMSF; the BIST 100 fell 21% below its May peak. The same week the sliding-scale system ended, and the tax on petrol will rise in steps over 3 months.

  1. 1

    Inflationwithin days

    The tax steps add a new tax-driven rise to inflation in each of October, November and December; in the Bloomberg HT survey the annual expectation for September is already 30.30%.

    Watch: September CPI on 3 October, and the tax on petrol rising to 11.36 TL on 1 November

  2. 2

    Rates and the currencywithin weeks

    As inflation expectations rise, the CBRT delays rate cuts; households hit by fund losses, expecting low returns, start shifting savings from lira into foreign currency.

    Watch: The MPC decision on 22 October and the 33% threshold on the 10-year yield

  3. 3

    Reserves and sovereign riskwithin months

    Household demand for foreign currency is met from the same reserves as an energy bill that stood at 6.464 billion $ in August; if gross reserves fall below 174.4 billion $, the sovereign risk premium starts to follow the losses in equities.

    Watch: Weekly CBRT reserve data and the 250 basis point threshold on CDS

What breaks the chain

If Brent falls below 97 $ and the energy bill shrinks, the third link weakens. If the board announces a swift payment timetable, it would keep households from turning to foreign currency and break the second link.
