Japan and the United States recently carried out their first coordinated intervention in the yen in more than two decades, aiming to stabilize the currency after it sank to its lowest level against the dollar in 40 years. The move is raising questions about global liquidity, the potential effects on Bitcoin (BTC), and the outlook for broader risk assets.
Rare coordinated intervention to support the yen
Last week, both countries jointly acted to halt the yen’s sharp decline, with the New York Federal Reserve selling euros on behalf of the US Treasury. The yen had weakened to 164 per dollar, prompting the intervention—the first such step since 1998. These sales tapped the US Treasury’s Exchange Stabilization Fund, which manages foreign exchange reserves.
The interventions illustrate deepening coordination between US officials and the Bank of Japan (BoJ) as they seek to shore up the currency without triggering instability in global markets, particularly the US Treasury market.
Impact on liquidity and Bitcoin
A major concern for market participants is the so-called “yen carry trade.” For years, global investors have borrowed at low rates in Japan to invest in higher-yielding assets abroad. If unwound rapidly, this trade could tighten global liquidity and impact a range of risk assets including cryptocurrencies like Bitcoin.
US Treasury Secretary Scott Bessent highlighted the partnership ahead of a planned meeting with BoJ Governor Kazuo Ueda at the G20 gathering in North Carolina this August. He emphasized the commitment of Prime Minister Takaichi, Governor Ueda, and the Bank of Japan toward monetary and financial stability, noting ongoing close cooperation between both countries.
Japan’s monetary authorities have shown a strong resolve to maintain stability while coordinating closely with Washington, as underscored by US officials’ support for recent market actions.
Japanese two-year government bond yields have surpassed 1.57%, reaching levels not seen for decades. The shift reflects changing expectations about Japan’s long-standing low interest rate stance and marks a potential end to an era of cheap borrowing in yen.
The BoJ remains one of the few central banks with access to the Federal Reserve’s Foreign and International Monetary Authorities (FIMA) repo facility. This arrangement allows Japan to access dollar liquidity without selling its holdings of US Treasuries.
Mini dictionary: FIMA repo facility, a Federal Reserve program that provides short-term dollar liquidity to foreign central banks and official institutions, using US Treasuries as collateral. This tool helps stabilize international markets without requiring central banks to sell their Treasury holdings.
Bessent called for expanding the FIMA facility, stressing its importance as a liquidity backstop. He reaffirmed American support for Japan’s measures to address the yen’s undervaluation. The facility’s usage increases the supply of dollars outside the US, providing potential relief during periods of heightened stress.
Mixed reactions and future outlook
Reactions to the intervention have been mixed. Economist Mohamed El-Erian remarked that Washington’s new approach ties its success to Tokyo’s alignment across key policymakers, including the Bank of Japan, Ministry of Finance, and the Prime Minister’s Office.
Washington has committed to a strategy that now relies on coordinated policy actions in Tokyo, making future outcomes harder to predict.
In the cryptocurrency sector, observers have expressed uncertainty about the long-term impact of ongoing interventions. Some note that, while such moves could passively benefit the Bitcoin bull case, the ultimate effect may depend on the disintegration of the yen carry trade and the evolution of Japanese fiscal policy.
Japan’s rising government bond yields signal a significant policy transition, making yen-based financing less attractive. As domestic investors shift assets back to Japan in response to these changes, the risk of a further unwinding of the carry trade could increase, tightening liquidity across global markets.
Both traditional and digital asset markets remain alert to these developments as authorities in Japan and the US attempt to balance currency stability and financial market health.
