In a notable development, the Federal Reserve's custody holdings of US Treasury securities fell by $8.7 billion to $2.73 trillion during a period when Japan was likely intervening to support its currency, the yen. Japan's Ministry of Finance is estimated to have spent about $54.7 billion on currency purchases, leading to speculation that the country may have sold US Treasuries to fund these interventions. This decline in Treasury holdings could exert upward pressure on US yields, which are already affected by rising oil prices and concerns regarding the widening fiscal deficit due to the ongoing conflict in Iran. Analysts suggest that if Japan's intervention becomes a regular occurrence, it could significantly impact the US Treasury market. The upcoming visit of US Treasury Secretary Scott Bessent to Japan is expected to address these currency market dynamics with key Japanese officials, including Prime Minister Sanae Takaichi and Finance Minister Satsuki Katayama. Historically, Japan's interventions have not significantly impacted its foreign-exchange reserves, indicating a potential deterioration in supply-demand conditions in the bond markets, particularly US Treasuries.
