What Is the Bid-Ask Exchange Rate?

The bid-ask exchange rate refers to the dual pricing for the same currency at a given moment: the price at which the platform sells to you (ask price) and the price at which the platform buys from you (bid price). The difference between these two prices is called the spread, also commonly known as the bid-ask spread.

You can think of it like a store’s “selling price” versus its “buyback price.” When a bank or trading platform sells you US dollars, they use the ask price; when you sell US dollars back, they use the bid price. These prices are not identical because they must account for operational costs, inventory risks, and market volatility.

How Does the Bid-Ask Rate Differ From the Mid-Market Rate?

The bid-ask rate is a pair of actual transaction prices, while the mid-market rate is a reference level between the two, indicating the average market value. The mid-market rate is not a unified price at which individuals can directly transact.

For example: If a bank quotes USD/CNY with an ask price of 7.25 and a bid price of 7.15, the mid-market rate is roughly 7.20. Many news sources or central banks publish the “mid-market rate” as a market anchor, but your actual transaction at a counter or platform will always follow the real-time bid-ask rates.

How Is the Bid-Ask Exchange Rate Determined?

The bid-ask exchange rate is determined by both supply and demand and risk management. Market makers—institutions providing both buy and sell prices—quote paired prices based on order book liquidity, inventory, and volatility.

The order book is the platform’s queue of buy and sell orders. When there are many buy orders and few sell orders, the ask price rises; when there are many sell orders and few buy orders, the bid price falls. Market makers also factor in trading costs, cash vs. wire transfer differentials, and market uncertainty into the spread to mitigate losses from extreme volatility.

How Are Bid-Ask Rates Used in Forex and Crypto Trading?

The bid-ask exchange rate determines your actual conversion price when exchanging money or cryptocurrencies. At a bank, you buy USD at the ask price and sell USD at the bid price. The same applies to crypto: in Gate’s fiat zone (OTC—over-the-counter trades directly with merchants), buying USDT with CNY uses the merchant’s ask price; selling USDT for CNY uses their bid price.

In Gate’s spot market (where you instantly swap one crypto for another), the matching engine executes trades at the best available bid and ask prices from the order book. The “latest price” you see is usually from a recent trade, but your actual transaction will always execute at the prevailing bid-ask rates.

What Risks Are Implied by Bid-Ask Spreads?

The spread represents an explicit transaction cost. The wider the spread, the greater your loss when buying and then selling the same asset, which reduces capital efficiency. Spreads can also widen sharply during periods of high market volatility, increasing transaction uncertainty.

As of the second half of 2024, public quotes from major domestic banks show that the cash USD/CNY spread for personal customers typically hovers around 0.5%, but this varies by bank, channel, and time of day. In crypto fiat OTC markets, spreads are even more sensitive to merchant inventory and payment channels. In addition to spreads, there is also slippage and fees. Slippage is the difference between your expected and actual execution prices, often occurring with market orders or in low-liquidity environments. Fees are explicit charges set by platforms or merchants—do not confuse them with spreads or slippage.

For fund safety, always use trusted channels, verify merchant credentials and counterparty risks, and be wary of unusually favorable rates that may indicate payout or compliance issues.

How to Check and Calculate Bid-Ask Exchange Rates?

You can check USD/CNY bid and ask prices on bank websites, online banking platforms, or at counters; on Gate’s OTC fiat page for merchant quotes; or on spot trading pages by observing the top bids and asks in the order book.

Step 1: Identify the ask and bid prices. Record both numbers with their corresponding time and source.

Step 2: Calculate the spread. Spread = Ask Price − Bid Price. This is your direct cost difference.

Step 3: Estimate cost ratio. Cost ratio ≈ (Ask Price − Bid Price) ÷ Mid-Market Rate, where Mid-Market Rate ≈ (Ask Price + Bid Price) ÷ 2. This estimates your theoretical loss if you “buy and immediately resell.”

Step 4: Apply to your amount. For example, if a bank quotes an ask price of 7.25, bid price of 7.15, mid-market rate of 7.20, spread is 0.10, cost ratio ≈ 0.10 ÷ 7.20 ≈ 1.39%. If you cycle ¥10,000 through a buy-and-sell roundtrip, your theoretical loss would be about ¥139—actual results may vary due to fees and slippage.

How Do Bid-Ask Rates Impact Buying USDT on Gate?

When buying USDT with CNY on Gate OTC, the merchant’s ask price determines how much USDT you receive per CNY; when selling USDT for CNY, it’s based on their bid price. The spread between these is your explicit fiat-side cost.

If you swap USDT for BTC on Gate’s spot market, the top ask in the order book sets your BTC purchase price; the top bid sets your BTC sale price. If you use a market order, low liquidity may cause slippage so that your execution price deviates from visible bids/asks.

Step 1: Choose an appropriate order type. Use a limit order to set your preferred price and reduce slippage risk.

Step 2: Monitor liquidity and depth. Trade during high-volume periods for execution closer to quoted bids and asks.

Step 3: Split large trades and estimate total costs. Break large orders into parts; consider spread, slippage, and fees together—not just headline rates—when calculating overall transaction costs.

How Are Bid-Ask Rates Related to Foreign Exchange Settlement and Cross-Border Payments?

All cross-border receipts and payments ultimately settle at a bid or ask exchange rate. When you receive USD from an overseas client and convert to CNY, the settlement institution uses the bid price; when paying USD to a supplier, they deduct using the ask price. For exporters, freelancers, and cross-border e-commerce businesses, understanding bid-ask spreads helps in negotiating prices and selecting payment channels.

In crypto payments, if a client pays in USDT but you withdraw as CNY, OTC fiat market ask and bid prices determine your final amount received. Opting for transparent quotes, stable channels, and compliant platforms helps minimize spreads and counterparty risk.

Summary of Bid-Ask Rates & Key Precautions

Bid-ask rates reflect true buy/sell prices at any given time; the spread is an explicit cost; the mid-market rate serves as a reference for comparison and calculation. These rates are shaped by supply/demand dynamics and risk management strategies—applicable across banking forex markets, Gate fiat OTC trading, and spot crypto transactions. When checking/calculating rates, record ask/bid/mid-market prices and estimate round-trip costs using simple ratios—add fees and slippage for a full picture. For fund safety and counterparty risk management, always use trusted channels and compliant platforms; avoid being misled by abnormal rates or hidden charges; optimize results by using limit orders or splitting trades during high-liquidity periods.

FAQ

What Exactly Are Cash Bid Price and Ask Price?

The cash bid price is what banks pay to purchase foreign currency from you; the ask price is what banks charge to sell foreign currency to you. In short: sell foreign currency at the bid price; buy at the ask price. These two prices are always different—banks earn profit through this spread.

Why Is There Always a Difference Between Bid Price and Ask Price?

The spread exists to compensate banks for risk and operational costs—they must maintain forex inventories, hedge risks, pay staff, and operate systems. The spread is their profit margin; larger differences indicate higher market risk or tighter liquidity.

What Is the Relationship Between Purchase Rate and Settlement Rate?

The purchase exchange rate applies when you buy foreign currency with CNY (using the ask price); the settlement rate applies when you convert foreign currency back into CNY (using the bid price). Both processes incur spread losses—frequent exchanges will increase these costs.

How Does the Bid-Ask Rate Affect My Transaction Price on Gate?

When depositing or withdrawing fiat on Gate, current bid-ask rates are referenced. When buying USDT with CNY, Gate uses the CNY/USD ask rate for conversion—the amount of USDT you receive fluctuates with these rates. Choosing liquid pairs with tight spreads minimizes this impact.

How Can I Quickly Judge If Current Bid-Ask Rates Are Favorable?

Compare with the mid-market rate: normally, the ask should be above and the bid below this level. If the spread exceeds 2%, that indicates significant divergence—consider waiting or using other channels instead. Referencing central bank-published mid-market rates helps identify potential overpricing.
