October 2025 Semi-Annual FX Turnover Survey Results: A Global Shift in Capital Flows and 3 Key Insights
Hello, this is Seji, Senior Editor at SejiWork.
The foreign exchange market, the vast capillary system of global finance, is the most vivid indicator of capital flows between nations and economic dynamics. Today, we are diving into the recently released results of the 'October 2025 Semi-Annual FX Turnover Surveys.' This survey carries more weight than ever, as it captures the reorganization of global liquidity following the turning point of the high-interest-rate environment seen over the past few years. Join me as we read between the lines of this data to forecast future macroeconomic trends.
Macroeconomic Implications of the October 2025 Survey Results
The October survey revealed that global FX turnover reached record-high levels. This is not merely an increase in the number of transactions; it signifies active portfolio rebalancing driven by geopolitical risk management and divergence in monetary policies.
Analysis of the Overall Increase in Trading Volume
In the second half of 2025, the interest rate paths of major central banks began to diverge. While the U.S. Federal Reserve (Fed) moved into fine-tuning mode aiming for a soft landing, Europe and Japan activated different inflation-response scenarios. These Interest Rate Differentials amplified exchange rate volatility, subsequently stimulating both speculative demand for exchange gains and hedging demand for risk aversion.
Changes in Currency Shares: USD Hegemony vs. Challenges
The most notable finding in this survey is the status of the U.S. Dollar (USD). While it still accounts for over 80% of global FX transactions, the share of certain emerging market currencies has risen significantly.
The Performance of the Yen (JPY) and the Euro (EUR)
Reflecting expectations for the Bank of Japan's (BoJ) normalization of monetary policy, Yen trading volume increased by approximately 12% year-on-year. This is analyzed as a phenomenon resulting from the repeated unwinding and re-entry of Yen carry trades. On the other hand, the Euro maintained its status as a safe haven and recorded stable trading volumes despite concerns over slowing economic growth in Europe.
Detailed Data Analysis by Transaction Type: The Start of Structural Change
To understand the qualitative changes in the FX market, we must look at data by transaction type. In the October 2025 survey, distinct shifts were captured in the FX Swaps and Outright Forwards markets.
The Overwhelming Dominance of FX Swaps
FX Swaps still account for more than half of the total transactions. This demonstrates that global corporations and financial institutions are actively using the swap market as a means to secure short-term dollar liquidity. In particular, the surge in demand for dollar funding from Asian banks is cited as a major driver of this volume increase.
Technical Evolution of the Spot Market
Spot market trading has become more volatile than in the past. This is due to the increased proportion of High-Frequency Trading (HFT) algorithms. Mechanistic data processing now often dictates market direction more than human judgment, suggesting a harsher market environment for individual investors.
Growth Background of Forwards and Options Trading
As demand to fix uncertain future values increased, forward trading rose in tandem. Interestingly, currency hedging demand for ESG-related investment assets has emerged as a new market driver. As the issuance of green bonds increases, FX derivative transactions linked to them have become more active.
Behavior of Market Participants and Technical Progress
The nature of the market changes depending on who is trading. The October 2025 data shows that the dominance of institutional investors has been further strengthened.
Proliferation of Algorithmic and AI Trading
It is estimated that approximately 70% of total FX transactions during this survey period were executed by algorithms. Since the introduction of Generative AI, 'Cognitive Trading'—which builds positions by interpreting news data and economic indicators in real-time—has become commonplace. While this technological advancement increases market efficiency, it also potentially raises the risk of a 'Flash Crash' where sell orders cascade in specific situations.
Potential Influence of Digital Assets and CBDCs
Although reflected in statistics to a limited extent, cross-border settlement experiments using Central Bank Digital Currencies (CBDCs) have begun to impact trading volumes. The phenomenon of 'financial convergence,' where the boundaries between traditional FX markets and digital asset markets blur, is beginning in earnest.
Comparative Analysis: 2024 vs. 2025 Market Dynamics
- Liquidity: If 2024 was a period of 'contraction due to interest rate hikes,' 2025 can be defined as a period of 'reallocation due to the interest rate turning point.' Transaction volumes increased by more than 15%.
- Risk Appetite: Last year saw a heavy tilt toward safe-haven assets, but this year is marked by selective investment in high-yielding emerging market currencies.
- Transparency: Attempts to introduce blockchain-based settlement systems have led to a significant improvement in the transparency of post-trade reporting.
