Author: John J. Hardy, Global Head of Macro Strategy

Overview
The article discusses the recent announcement by the US Treasury to double its buyback operations for longer-term treasuries, which has significant implications for the US dollar and global currency markets. The Treasury's decision signals a desire to prevent higher long-term yields, which could lead to a further decline in the US dollar.
Treasury Buyback Operations
The US Treasury announced an increase in its buyback program, moving from $2 billion to $4 billion in purchases of treasuries with maturities of 10 years or more. This operation is set to begin on September 9, ahead of the scheduled meeting on November 4. Although the amounts are relatively small, the announcement is seen as a strong signal against rising yields, particularly at the longer end of the yield curve.
Market Reactions
The announcement has led to a bearish outlook for the US dollar, as foreign holders of US treasuries may seek to hedge their USD exposure. This has resulted in a notable rally in the Swiss franc (CHF), which has been particularly affected by recent carry trades. The CHF rose significantly against both the euro and the US dollar following the announcement.
Impact on Other Currencies
In addition to the CHF, the Japanese yen (JPY) also saw a rise, although it did not react as strongly as the CHF. The article notes that the Treasury's actions provided relief for the Japanese Government Bond (JGB) market, with yields falling significantly. However, the yen's performance remained mixed, indicating ongoing volatility and intervention risks.
Future Implications
The article emphasizes the importance of the upcoming Jackson Hole speech by Kevin Warsh, which may provide insights into the Federal Reserve's stance on inflation and interest rates in light of the Treasury's actions. The potential for a dovish shift in Fed policy could further influence market dynamics, particularly regarding the US dollar and global currencies.
Conclusion
The Treasury's buyback announcement is a clear indication of its intent to control long-term yields, which could lead to a significant decline in the US dollar. The market's interpretation of this move will be crucial in determining the future trajectory of both the dollar and other currencies, particularly the CHF and JPY.
