You may be looking for the fixed handling fee rate when handling Bank of China cash to spot exchange business.
Please Note: This fee is not a fixed percentage. It actually stems from the spread between the bank’s “cash buying rate” and “spot buying rate,” which is usually between 1% and 3%.
Understanding this hidden cost is the first step to saving money for you. Mastering its calculation method and rules can help you effectively reduce unnecessary expenses.

The true nature of this “fee” is actually a spread in the bank’s foreign exchange rates. Understanding this spread allows you to take control of the costs.
When you deposit foreign currency cash into the bank, the bank uses the “cash buying rate” for calculation. If you want to convert this money into freely transferable “spot exchange,” the bank is essentially “buying” this money from you at the “spot buying rate” and depositing it as remittance.
Cash Buying Rate is always lower than Spot Buying Rate. This spread is the actual cost you bear.
Why Is There This Spread?
Banks incur additional costs and risks when handling foreign currency cash, which are reflected in the prices. Main reasons include:
- Physical Costs: Banks need to pay for transportation, storage, insurance, and anti-counterfeiting verification to manage physical currency.
- Capital Occupation: Foreign currency cash in inventory cannot generate interest like electronic remittances, occupying bank funds.
- Market Risk: If the exchange rate falls while the bank holds cash, it faces direct loss risks.
- Profit Model: Banks profit through the spread between buy and sell prices, which is one of the basic models of banking business.
Therefore, the fee generated when handling Bank of China cash to spot exchange business is not an additional service fee charged by the bank but a necessary spread to cover its costs and risks.
You can use a simple formula to accurately calculate this fee. This allows you to know the cost before handling the business.
Calculation Formula
Fee Amount = (Spot Buying Rate - Cash Buying Rate) × Foreign Currency Cash Amount
Calculation Example
Suppose you have 1,000 USD cash and want to handle Bank of China cash to spot exchange.
We query the bank’s foreign exchange rate on that day (note that rates change in real time; this is only an example):
Now, let’s calculate your “fee”:
- Calculate Spread: 6.85 - 6.80 = 0.05
- Calculate Total Cost: 0.05 × 1,000 USD = 50
This means converting 1,000 USD cash to spot exchange requires bearing a cost equivalent to about 50 RMB. This amount is directly deducted from your total after exchange, not charged as a separate fee.

After understanding the fee calculation method, the real key is how to cleverly reduce or even avoid this expense. Rather than passively accepting spread losses, proactive planning is better. The following three major techniques will help you become a smarter currency user.
The most effective money-saving method is to avoid unnecessary “cash to spot” operations from the source. Before handling business, ask yourself a core question: How do I plan to use this foreign currency in the future?

For specific digital payment scenarios, you can explore alternatives beyond banks. For example, some emerging fintech platforms can help you manage digital assets and make global payments. Using tools like Biyapay may allow you to complete payments directly, bypassing traditional banks’ complex “cash to spot” processes, which might be a shortcut to saving costs.

You can proactively contact your relationship manager or check mobile banking membership benefits to see if you qualify for the following benefits:

Please Note: The above table is for illustration only. Specific benefit policies and spread reductions are subject to your bank’s latest announcement. Proactive inquiry ensures your benefits are maximized.
“Cash to spot” business is strictly restricted by foreign exchange management policies. Understanding and complying with these rules not only makes your business handling smoother but also helps avoid unnecessary trouble.
The most critical regulation is about daily handling limits.
Core Policy: Daily Limit Restriction
According to mainland China’s foreign exchange management regulations, individuals handling cash to spot exchange business:
- Daily cumulative amount at or below equivalent of $5,000 USD, you can handle directly with valid personal ID.
- Daily cumulative amount exceeding equivalent of $5,000 USD, you must provide relevant cash source proof materials to the bank, such as overseas withdrawal records or customs declarations.
Therefore, the simplest strategy is daily handling amount not exceeding $5,000 USD.
However, there is an important reminder: Do not attempt to “split” transactions to evade regulation.
Bank systems monitor abnormal transaction behavior. If you handle, for example, $9,000 by doing $4,500 each day for two consecutive days, this pattern may be flagged by the system as “structured transactions” or “splitting transactions”.
The following behaviors may trigger the bank’s anti-money laundering monitoring system:
Once your account behavior is deemed suspicious, you may face transaction rejection, enhanced account monitoring, or even usage restrictions. Compliant handling is the safest and wisest choice.
After mastering money-saving techniques, familiarizing yourself with the specific handling process can make it twice as effective with half the effort. This detailed guide will lead you to complete operations easily.
Preparing complete materials is the first step for smooth business handling. You need to prepare corresponding documents based on your identity.
