How it is calculated
The amount is converted to dollars at the average rate for the chosen year and compared with the same amount kept in the national currency. Today’s value uses the current rate.
In national currency = amount × (1 + rate)years
How the tenge has changed
In 2008 a dollar cost about 120 ₸. The tenge was sharply devalued in February 2009 and February 2014, and in August 2015 Kazakhstan moved to a free-floating exchange rate, after which the tenge lost almost half its value within a few months. In 2025 the average rate exceeded 500 ₸ per dollar.
For savings this is the main risk: capital in one currency loses value all at once, and sharply — in days, not years.
- The rate is the National Bank of Kazakhstan’s official annual average dollar rate; for 2026, the year-to-date average.
- The calculation ignores taxes, fees and dollar inflation.
- The past does not guarantee the future: a currency can also strengthen.

FAQ
When was the tenge devalued?
The major devaluations were in February 2009, February 2014 and August 2015, when the National Bank moved to a free-floating rate. Since then the tenge has gradually weakened against the dollar, with periods of strengthening.
Where does the exchange rate data come from?
We use the National Bank of Kazakhstan’s official annual average dollar rate. The current rate is loaded automatically; if it is unavailable, the year-to-date average is used.
Would a tenge deposit have been better?
Tenge deposit rates partly offset devaluation. Enter an average rate in “Return in tenge” for a fair comparison: a tenge deposit against a dollar one.
Should I keep all my savings in dollars?
No. It makes sense to keep the next few months of expenses in the currency you spend, and to spread long-term capital across currencies and countries. Exactly how depends on your goals, country of residence and risk profile.
