One headline rarely explains the exchange rate
USD/TRY is the relative price of two currencies. It reflects developments in Türkiye as well as the US dollar and global funding conditions. A rate decision, inflation release or political headline may dominate one session, while the price can already contain earlier expectations. A sound explanation considers rates, inflation expectations, FX flows, risk premia and the global dollar together. The driver of an intraday move may differ from the driver of a multi-month trend.
Expected real return matters more than the headline rate
The level of lira interest rates is not enough. Investors compare expected inflation over the holding period, taxes and costs, currency risk and returns in comparable markets. In a simplified example, a 35% net lira return with 30% expected inflation produces an exact expected real return of 1.35 divided by 1.30 minus one, or 3.85%. If expected inflation rises to 40%, the same nominal return becomes roughly minus 3.57% in real terms. These are illustrations, not market forecasts.
| Channel | Data to watch | What it cannot establish alone |
|---|---|---|
| Lira rates | Policy rates, market rates and expected inflation | The exchange rate’s certain direction |
| FX flows | Current account, tourism, export and import payments | The intraday price |
| Risk premium | Bond yields, country risk and global volatility | A permanent valuation |
| Global dollar | Dollar indices, the Fed and US rates | A Türkiye-specific cause |
Where FX supply and demand come from
Exports, tourism, direct investment and external borrowing can supply foreign currency. Imports, debt repayments, profit transfers and residents’ portfolio choices can create demand. The current-account balance summarises important flows but does not show all timing details. Month-end corporate payments, public debt service or seasonal tourism receipts can affect the short-term balance. Reserve changes should not be labelled simply as purchases or sales without separating valuation, swaps and other balance-sheet items.
How to build a TRY100,000 currency scenario
Assume TRY100,000 is converted at 32.00 with no fees or spread, buying USD3,125. At an ending rate of 35.20, the lira value is TRY110,000, a nominal gain of 10%. Real transactions use different buying and selling rates. With an illustrative 1% spread at both entry and exit, fewer dollars are bought and the exit price is below the reference rate; the result falls to about TRY107,811. Taxes, custody costs and interest are excluded. The quoted exchange-rate change is therefore not the investor’s net return.
Align dates and frequencies
Comparing a daily exchange rate directly with monthly inflation or an annual interest rate with a one-week currency move is misleading. Use matching start and end dates, time zones and price definitions. TCMB EVDS contains different buying, selling and indicative series, so identify the one used. A weaker lira does not automatically mean profit for every exporter or loss for every importer; revenue currency, imported inputs, debt, maturity and hedging determine the company impact.
