Turkey's Lira Looks Like a 37% Yield. The 23.7% Inflation Number Explains Why It Isn't.

Here is an inflation chart that should fascinate any income investor, because it is a laboratory for the single most important question in money: does a high nominal return survive inflation and currency erosion?

Turkey's central bank has held interest rates at 37% for five straight meetings, and a lira savings account yields double-digit interest that would make any US saver's eyes water. Yet the same central bank's own survey of banks, funds, and corporate treasurers puts consumer price inflation at roughly 23.7% over the next twelve months. That gap — a policy rate that looks enormous next to a number the market itself expects to stay near a quarter — is the whole story.

Inflation expectations are the leading indicator

The 23.7% figure comes from the Central Bank of Turkey's monthly Survey of Market Participants, the poll the country's policymakers watch more closely than almost any other. It is worth understanding why the number deserves that attention.

Central banks fight inflation with rates, but inflation is made by people — by a shopkeeper raising a price, a landlord renewing a lease, a union settling a wage. Each of those actors sets numbers based partly on what they expect everyone else to do. Price expectations are therefore a leading indicator of prices themselves: if businesses and households expect 25% inflation, they build it into their pricing and pay demands, and inflation follows. The 23.7% reading is not a prediction so much as a measurement of what a big slice of the Turkish economy is already doing.

That is why the number carries the interpretation. Actual inflation has been falling — annual CPI cooled to 31.5% in August, its lowest reading since March, down from months stuck near the low-30s — but the market still expects a quarter of price rises over the coming year. That is progress, not victory. Two years ago inflation was running above 75%; the expectation has converged from catastrophe toward something merely very high. But it remains stubbornly above the central bank's own official roadmap of 24% by end-2026 and 15% by end-2027. Expectations are drifting down slower than the authorities would like, which is exactly why rates have sat at 37% through five consecutive decisions.

The yield that isn't what it looks like

Now the part that matters for a US investor deciding whether any of this belongs in a portfolio.

At 37% nominal against 23.7% expected inflation, the lira's "real" rate — the return above inflation, the one that actually builds purchasing power — looks deeply positive on paper. That is precisely the kind of real yield that forms the core of the standard bullish case for countries running tight-money disinflation programs. It is real, but it is not the windfall it appears to be.

The reason is currency. A lira yield is only a gain to a dollar-based investor after the lira's slide against the greenback is subtracted. And the survey participants who expect 23.7% inflation also expect the lira to keep depreciating: they project the dollar to rise from roughly 48.5 liras today to above 51 by year-end and above 54 a year out. Convert a lira deposit back to dollars at those levels, and a good chunk of the 37% gets handed back in exchange-rate loss. What looked like a spectacular carry is, in real, dollar terms, a modest and increasingly fragile one.

This is the trap at the heart of "chase the yield" thinking, in Turkey or anywhere: a high nominal rate is not an inflation-protected return, and a local-currency yield is only as good as the currency. When a country is running 31% inflation with expectations at 24%, the currency risk is not a footnote to the trade — it is the trade.

What the number means for a real portfolio

Strip away the speculation and a definition question remains: how does a US investor sensibly participate in a country that is disinflating, if at all?

The honest answer is that this is not an income trade. The pure lira carry is a currency trade wearing an income costume, and it carries the additional, uncounted risk that the program breaks — a global energy shock, a political shift, or a decision to ease before expectations are anchored. A hold of Turkish assets through a dedicated vehicle such as the iShares MSCI Turkey ETF exposes an investor to both sides of the disinflation at once: real-economy companies with genuine pricing power and hard-currency export earnings gain when the lira is cheap, but domestic-demand businesses are squeezed hard by 31% inflation and deeply restrictive rates.

If there is a rule the 23.7% number enforces, it is the same one that governs every asset in an inflation regime: do not buy the headline yield, buy the thing that can hold its purchasing power. For that, the watchable variable is not the rate or the monthly CPI print but the expectation itself. Each survey in which 23.7% keeps falling — toward the central bank's 24% and beyond — is evidence that the disinflation is being earned rather than assumed. The day market expectations stop expecting a quarter of future inflation is the day Turkish assets stop being a speculation and become a quality-at-a-price consideration. Until then, the only number that matters is the one the market is already showing you, and it is not in your favor as an income play — even if the interest rate reads like a dream.
