Liquidity Dynamics in Japan's Equity Market

This document is a report that examines the liquidity conditions in Japan's equity market during March 2026. It outlines how the apparent strength of liquidity was deceptive, as execution outcomes were influenced more by factors such as queue position, urgency, and timing rather than the visible depth of liquidity. The report details a significant bid-side skew in displayed liquidity, which created competitive queues for buy orders and thinner protection for sell orders during periods of volatility. It highlights that while top-of-book liquidity increased, its stability did not improve, leading to execution outcomes that were sensitive to changes in liquidity dynamics. The report emphasizes the importance of adaptive urgency and the use of dark liquidity to enhance execution quality, particularly in a market characterized by high volatility and bid-heavy conditions. Overall, it concludes that effective execution relied on traders' ability to access and convert liquidity rather than merely on the amount displayed on the screens.
