The United States Department of the Treasury released its International Capital Flow report on January 17, indicating notable changes in foreign investments, particularly in U.S. Treasury securities. Among the key players, Japan, traditionally the largest holder of U.S. debt, has seen a slight decline in its holdings, while China has made some gains. The dynamics of these changes are reflective of not just economic strategies but are also intertwined with geopolitical tensions and currency stabilization efforts.

In November, Japan’s holdings of U.S. Treasury bonds dropped by $3.1 billion, settling at $1.0988 trillion. This decline follows a short-lived increase during August, but soon after, the trend shifted back to decreasing levels. Since overtaking China’s holdings in June 2019, Japan has maintained its status as the largest foreign owner of U.S. debt. However, the volatility of the yen has prompted Japanese authorities to adjust their strategies regarding U.S. Treasury holdings as they navigate the complexities of foreign exchange pressures.

The financial markets have been closely watching these shifts in Japanese Treasury holdings, particularly as they often signal necessary adjustments in response to intervention efforts aimed at stabilizing the yen. In the currency exchange market, fluctuations in the yen's exchange rate can be dramatic. During turbulent periods, the government often requires significant “ammunition” to effectively intervene. In this context, reducing dollar-denominated assets, including U.S. Treasury bonds, becomes a vital source of funds. In July alone, there were reports indicating that Japan had invested up to $36.6 billion in market interventions aimed at boosting the value of the yen.

Despite the chaotic nature of the foreign exchange market, there was a significant rebound in the yen's value during August and September, temporarily alleviating the immediate pressures on the Japanese government to support its currency. A stable exchange rate can diminish the urgency to divest in U.S. Treasuries as a method of forex intervention, which meant that Japan's motivation to sell off U.S. debt took a backseat for a brief period. Unfortunately, this reprieve was short-lived; since October, the yen has faced a downward spiral, recently hitting a new six-month low against the dollar and hovering near the critical threshold of 160. However, the recent market optimism fueled by rising expectations for a interest rate hike by the Bank of Japan has provided a much-needed lift for the yen.

Shifting the focus to another major player, China’s holdings of U.S. Treasury bonds experienced an increase of $8.5 billion in November, bringing the total to $768.6 billion. Since peaking above the $1 trillion mark back in April 2022, China's investments in U.S. debt have consistently remained below that figure, yet it continues to rank as the second-largest holder worldwide, following Japan. The past year has seen fluctuations, with eight months of decline overshadowing the increases noted in April, June, and November—at least partially driven by rising bond prices during those months.

Examining the broader landscape among the top ten countries and regions holding U.S. Treasury bonds, the data reflected a general uptick in holdings for the majority as of November when compared to October figures. The United Kingdom observed an increase of $22.3 billion, bringing its total holdings to $765.6 billion, placing it merely $3 billion shy of China's position. Conversely, the Cayman Islands reduced their holdings by $12.7 billion, settling at $397 billion, depicting a mixed bag among U.S. treasury investors.

Analyzing the overall performance of major assets in November, it was a notable month for U.S. financial markets, with the Dow Jones Industrial Average rising by 7.5% and the S&P 500 Index climbing 5.7%, marking their best monthly performances for 2024. Long-term U.S. government bond yields decreased significantly, with the 10-year benchmark yield dropping over 11 basis points and the 2-year yield falling by more than 2 basis points, reflecting investor confidence and market dynamics.

The Treasury Department's TIC data paints a detailed picture of global capital flows, revealing a robust net inflow of foreign capital amounting to $159.9 billion in November. This significant influx comprised $156.6 billion from private investments and $3.3 billion from official entities. In the sphere of long-term securities, foreign investors were particularly active, making net purchases totaling $115.7 billion during the same period, predominantly sourced from private investors who accounted for $124 billion of that figure. Meanwhile, foreign official institutions were net sellers, offloading $8.3 billion in securities. Interestingly, American investors also increased their investments in long-term foreign securities, with net purchases reaching $36.7 billion.

The complexities of these transactions, including adjustments such as estimating foreign investment portfolios through stock swaps to acquire U.S. equities, led to a final estimate for net purchases of foreign long-term securities totaling $79 billion in November. Additionally, foreign holdings in U.S. Treasury securities grew by $11.3 billion, while short-term securities expressed a broader trend of increased dollar-denominated liabilities within the banking sector, which increased by $60.3 billion. This emphasizes the interconnectedness of global financial markets and the ongoing interplay of capital flows across regions and economies.

Finally, it's important to note that the Treasury Department's TIC data for December is set to be released on February 18, 2025, promising to provide further insights into the evolving relationships between international investors and U.S. treasury securities as these players navigate an ever-complex economic landscape.
