Recently, the dollar liquidity supply measures quietly launched by the Bank of Japan have sparked widespread discussions in the financial community about the potential risks to the global economic system.

In mid-July, the Bank of Japan announced that it would provide US dollar funding to the market through a pooled collateral approach. This seemingly ordinary liquidity management operation, however, is viewed by some macro analysts as a potential indication that more serious systemic risks are brewing.

This viewpoint is mainly based on the observation of the increasing internal pressures within the global dollar financing ecosystem, as well as the cumulative effects of the tightening policies continuously adopted by the Federal Reserve.

In-depth analysis reveals that the reason behind the Bank of Japan's actions is to address the challenges faced by domestic financial institutions. For a long time, these institutions have been accustomed to borrowing yen at low interest rates and converting it into dollars for investment. However, as the Federal Reserve raises interest rates leading to an increase in dollar rates, coupled with the continued depreciation of the yen, this arbitrage strategy is under immense pressure.

From a more macro perspective, this action by the Bank of Japan reflects the grim reality of tightening global dollar Liquidity. When a central bank of a country has to intervene to provide dollar Liquidity, it often means that market participants are facing difficulties in the allocation and management of dollar funds.

Throughout history, similar situations have occurred during the 2008 financial crisis, the 2011 European debt crisis, and the period of 2019-2020. This inevitably raises concerns about whether the current financial environment is brewing a new round of global economic challenges.

Although the Bank of Japan emphasizes that this is a preventive measure rather than a crisis response, the market remains highly attentive to it. As the global economic situation continues to evolve, the policy direction of central banks in various countries and its impact on global financial stability will continue to be a focal point of close attention for investors and analysts.
