Transaction liquidity refers to the ability of assets to be quickly bought and sold at reasonable prices in financial markets. Here are some important aspects of it:

Measuring Indicators

- Bid-ask Spread: The difference between the buy and sell prices set by market makers; a smaller spread indicates higher liquidity. For example, the spreads of major currency pairs in the foreign exchange market are usually small.

- Trading Volume: Reflects the activity level of the market; a large trading volume indicates active trading and good liquidity, such as large-cap blue-chip stocks often having high trading volumes in the stock market.

- Market Depth: Refers to the amount of large transactions that the market can accommodate without significantly impacting prices; a market with good depth can withstand larger buy and sell orders with minimal price fluctuations.

Importance

- Enhancing Market Efficiency: Allows investors to quickly enter and exit the market, reduces transaction costs, and promotes effective resource allocation.

- Stabilizing Market Prices: Adequate liquidity can buffer the impact of large transactions on prices, making prices more stable and reasonably reflecting the true value of assets.

Influencing Factors

- Number of Market Participants: The more participants there are, the easier it is for buyers and sellers to match, resulting in better liquidity. For instance, large stock exchanges have strong liquidity due to numerous participants.

- Characteristics of Trading Products: Standardized and homogeneous products, such as gold futures, tend to have better liquidity; while complex derivatives or non-standardized assets may exhibit poorer liquidity.

- Market Information Transparency: In markets where information is public and transparent, investors can better assess asset values and are more willing to engage in transactions, leading to higher liquidity.

Transaction liquidity is a key factor for the healthy functioning of financial markets, significantly impacting investor decision-making and the overall functionality of the market.
