Before formally starting the operation, spending a few minutes on preparations and checks can ensure the entire process goes smoothly. It’s like a chef preparing all ingredients before cooking, making you more at ease in subsequent steps.
First, you need to log into the Bank of China mobile banking APP and check your foreign currency account. The most critical point is to ensure your account holds the foreign currency “cash” balance that needs conversion.
Only balances clearly marked as “cash” in the account can be converted using the method we introduce. At the same time, you need to understand your annual foreign exchange settlement and purchase quota. According to China’s foreign exchange management regulations, each person has an annual quota equivalent to 50,000 USD. Although cash-to-remittance conversion itself does not occupy this quota, understanding the quota status helps you plan future foreign currency usage.

This is a standard risk assessment process; you just need to complete identity verification and questionnaire as prompted on the screen.
The preparations are very simple, with almost all tools on your phone.
Confirming these information in advance are accurate will pave the way for the upcoming Bank of China cash-to-remittance conversion operation, allowing you to complete the entire process in minutes.

Preparations are ready; now let’s enter the core part. You’ll see the entire operation process is very intuitive; just follow the five steps below to easily complete Bank of China cash-to-remittance conversion.
First, unlock your phone and open the Bank of China mobile banking APP. After successful login, you’ll see the homepage. In the common functions area on the homepage, you need to find and tap the “Foreign Exchange Settlement and Purchase” icon. This function is the core entry for all foreign currency-related transactions.
Tip If you can’t find “Foreign Exchange Settlement and Purchase” on the homepage, you can tap “All” or “More” button to search in the full services list. You can also use the top search box to directly search “Foreign Exchange Settlement and Purchase” for quick location.
After tapping “Foreign Exchange Settlement and Purchase”, you’ll enter a new page. Here, you’ll see multiple foreign exchange-related options. You need to select “Foreign Currency Exchange”. This option is specifically for conversions between different foreign currencies or same currency cash/remittance attributes.
This is the most critical step in the entire process. After entering the “Foreign Currency Exchange” interface, you’ll see “Sell” and “Buy” options.
By setting sell and buy to the same currency’s “cash” and “remittance”, you achieve the cash-to-remittance operation.
Why Do This? You might wonder why convert cash to remittance. The main reason is that remittance currency typically has higher value than cash. Banks bear costs like transportation, storage, and counting for physical foreign currency cash, reflected in the exchange rate. Therefore, telegraphic transfer (TT) rates are usually more favorable than cash rates. For example, cash rate spreads (bid-ask) may be as high as about 2.27%, while spot rates close to TT may have spreads as low as 0.326%. This means after converting to remittance, whether for overseas remittance or other uses, you get higher value.
The table below shows USD or HKD buying rates at different institutions to help understand cash vs. remittance differences.
| Institution Name | Cash Buying Rate (USD/HKD) | TT Buying Rate (USD/HKD) |
|---|---|---|
| Hang Seng Bank | 7.7750 | N/A |
| HSBC | 7.7750 | N/A |
| Bank of China (Hong Kong) | 7.7750 | N/A |
| Fubon Bank | N/A | 7.7750 |
| Shanghai Commercial Bank | N/A | 7.7750 |
| Nanyang Commercial Bank | N/A | 7.7750 |
| Bank of East Asia | N/A | 7.7750 |
After selecting correct currency and cash/remittance attributes, next enter the cash amount you wish to convert in the “Sell Amount” box. After input, the system automatically calculates the remittance amount you can get. Since it’s same-currency conversion, this amount is usually 1:1, with no exchange rate losses.
Before tapping next, carefully verify all information:
