In a newly released report, the Turkish Statistical Institute (TÜİK) has detailed the real return rates of financial investment instruments for July 2025. The data, adjusted by both the Domestic Producer Price Index (D-PPI or Yİ-ÜFE) and the Consumer Price Index (CPI or TÜFE), offers key insights into which financial assets outperformed others in terms of protecting investor purchasing power — and which failed to deliver.
July’s Star Performer: BIST 100 Index Surges in Monthly Returns
According to the report, the BIST 100 index delivered the highest real return in July, posting an 8.75% monthly gain when adjusted for Yİ-ÜFE and an 8.4% gain when adjusted for TÜFE. This marks a notable rebound for the Turkish stock market, which has struggled throughout the year due to monetary tightening, global uncertainties, and inflation volatility.
In contrast, government domestic debt securities (DİBS) came in second, offering a 3.68% real monthly return by Yİ-ÜFE standards, and 3.34% by TÜFE. Meanwhile, traditional savings such as deposit interest (gross) provided modest gains of 1.79% (Yİ-ÜFE) and 1.46% (TÜFE) respectively.
Gold Struggles in Short-Term Performance
Surprisingly, bullion (physical gold) posted a 0.47% real loss (Yİ-ÜFE) and 0.79% (TÜFE), making it the worst performer for the month of July. Despite its reputation as a safe-haven asset, gold failed to maintain its real value in the face of Türkiye’s rising inflation and stronger returns from equities.
Similarly, foreign currencies like the euro and dollar delivered minimal gains or losses. The euro provided a 1.47% return (Yİ-ÜFE) and 1.15% (TÜFE), while the U.S. dollar eked out just 0.17% (Yİ-ÜFE) and incurred a slight 0.16% loss (TÜFE).
3-Month Outlook: Government Bonds Lead the Pack
Looking at the three-month trend, DİBS continues to shine with a 6.12% real return (Yİ-ÜFE) and an even better 7.92% (TÜFE). This marks government securities as the most consistent performer during the short-term horizon — a trend largely attributed to recent central bank policies and the attractiveness of fixed-income instruments amid interest rate hikes.
Meanwhile, the dollar registered the steepest three-month loss, coming in at -1.25% (Yİ-ÜFE), making it the least profitable option. From a CPI standpoint, it offered a mere 0.43% return, further underperforming against domestic instruments.
6-Month Perspective: Gold Reclaims Glory
While gold floundered in July, its six-month performance was nothing short of stellar. Bullion offered a real return of 21.98% (Yİ-ÜFE) and 22.87% (TÜFE) — placing it well ahead of other instruments and reasserting its long-term value during times of monetary uncertainty.
However, the BIST 100 index delivered the sharpest six-month loss, with a -8.92% return (Yİ-ÜFE) and -8.26% (TÜFE). This underscores the volatility of Turkish equities in the face of macroeconomic risks and shifting investor sentiment.
Annual Review: Gold Dominates, Stocks Disappoint
Over a 12-month period, gold clearly stands as the top-performing asset for Turkish investors. According to TÜİK, it delivered a 37.17% real return (Yİ-ÜFE) and 27.58% (TÜFE). Despite short-term fluctuations, gold has maintained its stronghold as a hedge against inflation and currency devaluation.
Meanwhile, mevduat faizi (gross deposit interest) provided relatively attractive gains: 15.46% annually (Yİ-ÜFE) and 7.39% (TÜFE). Euro investments delivered a more modest 6.06% (Yİ-ÜFE) and 1.35% (TÜFE).
In contrast, equities took the hardest hit. The BIST 100 index posted a devastating -23.17% annual return (Yİ-ÜFE) and a -28.54% loss (TÜFE). This positions it as the worst-performing financial instrument over the last year, reflecting both domestic and global headwinds.
Foreign Currency Loses Its Luster
The once-reliable U.S. dollar also lagged in long-term performance. For the 12-month period:
Yİ-ÜFE-adjusted return: -1.59%
TÜFE-adjusted return: -8.47%
The data suggests that despite fluctuations in exchange rates and geopolitical events, foreign currencies have not effectively shielded investors from inflationary erosion — particularly when measured against gold or domestic debt securities.
Insights and Implications for Investors
The TÜİK report paints a clear picture: diversification and time horizons matter more than ever in 2025. Investors who stayed in equities or dollars lost significant purchasing power, while those with exposure to gold or government bonds saw positive real gains.
Key takeaways for investors:
Short-term equity spikes, like July’s BIST rally, can be deceptive in an overall downtrend
Gold remains a reliable inflation hedge, particularly over six- to twelve-month periods
DİBS offers stable returns, especially for conservative investors seeking security amid high inflation
Currency-based strategies are volatile, with dollar and euro investments underperforming against local benchmarks
Contextualizing the Data with Türkiye’s Economic Environment
Türkiye has been grappling with elevated inflation, aggressive monetary tightening, and exchange rate volatility for several quarters. As of July, inflation metrics continue to challenge investor confidence, despite the Central Bank of Türkiye’s (TCMB) persistent efforts to stabilize the economy through interest rate hikes and structural reforms.
The July inflation data had not yet been fully factored into market expectations at the time of the report, but the real returns underscore a wider trend: high nominal returns mean little unless they outpace inflation — and only a few instruments currently do.
What Lies Ahead for Financial Markets in Türkiye?
With upcoming economic reports, including TCMB’s 2025-III Inflation Report due in mid-August, investors will be closely monitoring forward guidance. Inflation projections, interest rate policy, and political stability will all influence the performance of investment instruments through the rest of the year.
Analysts suggest maintaining a diversified portfolio, with exposure to:
Inflation-resistant assets like gold
Fixed-income instruments such as government bonds
Short-term deposits in high-interest environments
Selective stock market positions with inflation-adjusted returns
Gold Is Still King in a Volatile Market
While monthly returns may favor the stock market or other risk-on assets, long-term performance tells a different story. Gold’s strong showing across six and twelve-month horizons proves that traditional safe havens still offer the best protection in times of economic uncertainty.
For investors in Türkiye, navigating 2025 will require a balance between short-term gains and long-term security. With inflation still shaping every financial decision, TÜİK’s real return data offers a valuable compass in an otherwise stormy investment landscape.
