How Hong Kong Businesses Can Send Money to the US: ACH, SWIFT & Payment Platforms

Key Takeaways

• Hong Kong businesses can send money to US recipients through SWIFT, US local ACH, and business payment platforms, depending on the recipient's bank details, payment amount, and urgency.
• For recurring USD payments, using US local payment rails such as ACH can reduce reliance on correspondent-bank transfers.
• The real cost of a US transfer includes more than the advertised transfer fee: businesses should compare FX spread, transfer fees, intermediary charges, and receiving fees.
• Businesses making frequent US payments may benefit from a USD or multi-currency business account that allows them to hold USD and pay US recipients without converting HKD for every transaction.

If you run a business in Hong Kong and need to pay a supplier, contractor, or subsidiary in the United States, you have more than one route. The three that matter most are a SWIFT wire, a US local ACH transfer, and a multi-currency business payment platform. The right choice depends on whether the recipient has a US bank account, how often you pay, whether you already hold USD, and what the transfer actually costs once FX spreads and intermediary fees are included. This guide walks through each option, the trade-offs, and how to pick the one that fits your payment pattern.

Best Ways to Send Money from Hong Kong to the US

The comparison below summarises the main routes before the detailed explanations.

SWIFT Transfer to the US

SWIFT remains one of the most established ways for Hong Kong businesses to send funds to a US bank account. It is a bank-to-bank message network, not a settlement system itself: your sending bank instructs a chain of institutions to move the money to the recipient's US bank.

When SWIFT makes sense

• Large-value business payments
• Payments where the recipient specifically requires a wire
• Transactions requiring formal banking records
• Suppliers that do not accept ACH
• International payments outside US local rails

What to watch

• Sending fee
• FX spread
• Intermediary bank fees
• OUR / SHA / BEN fee arrangements
• Bank cut-off times
• Possible payment delays
• Return fees if recipient details are incorrect

ACH Transfer to a US Bank Account

ACH is the US domestic electronic payment network. For a Hong Kong business, the key question is not whether Hong Kong banks generally provide ACH directly, but whether your payment provider can access US local payment rails. Many Hong Kong businesses reach ACH through a business payment platform that connects to the US domestic system, rather than through a local bank branch.

Why businesses use ACH

• Recurring supplier payments
• Contractor payments
• SaaS subscriptions
• US operating expenses
• Marketplace-related payments
• Other regular USD disbursements

What information is usually required?

• Recipient name
• US bank account number
• ABA / routing number
• Account type
• Recipient address where required
• Payment reference / purpose where required

Use a USD Business Account

For businesses that send money to the US regularly, the more important question may be:

Do I need to send money from Hong Kong every time, or should I hold USD first?

A USD business account can allow a company to:

• receive USD
• hold USD
• convert HKD to USD when needed
• pay US suppliers from USD
• avoid unnecessary repeated FX conversions

This is particularly relevant for businesses with recurring US expenses, and it is the same logic behind a multi-currency business account that holds several currencies at once.

Use an Online Business Payment Platform (PhotonPay)

For businesses making frequent international payments, a payment platform can combine several functions that would otherwise live in separate bank relationships:

• multi-currency balances
• FX conversion
• local payment rails
• international transfers
• supplier payments
• contractor payments
• payment tracking

PhotonPay provides businesses with a next-generation payment operating system for managing supported fiat and stablecoin balances, currency conversion, and global business payments. For a Hong Kong business paying US suppliers or contractors, the workflow is simple: hold or receive USD, convert when needed, and send USD to the US recipient. Where a business already holds stablecoins, supported USDC and USDT balances can be converted to USD and paid out — funding the payment flow with stablecoins rather than converting HKD each time.

Key capabilities to highlight

• Multi-asset business money management — hold and move several currencies from one place instead of maintaining separate bank relationships.
• Supported USD payment flows — pay US suppliers and contractors in USD through local and international rails without forcing a conversion on every transaction.
• Fiat & Stablecoin conversion — convert HKD to USD (or other currencies) when it suits your cash position, not on every payment.
• Global business payouts — reach recipients through both US local rails and SWIFT from a single platform.
• USDC and USDT payment capabilities where applicable — fund eligible payment flows with supported stablecoin balances as an alternative to repeated fiat conversion.
• API-based payment workflows — connect payment operations to your own systems for automated, reconcilable disbursements.

PhotonPay should not be positioned as simply a cheaper SWIFT replacement. It is a broader business payment platform that brings holding, conversion, cards, and payouts into one operating system.

ACH vs SWIFT: Which Should a Business Use?

The key point:

If the recipient can accept ACH and your provider supports US local transfers, ACH may be more efficient for recurring USD business payments.

How Much Does It Cost to Send Money from Hong Kong to the US?

Do not compare providers using transfer fees alone. Several layers can sit between the headline fee and what the recipient actually receives.

FX Spread

HKD → USD conversion may include a provider markup. A seemingly low transfer fee can be offset by a wide spread on the exchange rate.

Transfer Fee

The provider may charge a fixed or percentage-based fee per transaction.

Intermediary Bank Fee

SWIFT transfers may involve correspondent banks that deduct a fee along the way, especially under BEN or SHA charge arrangements.

Receiving Fee

The US receiving bank may charge an incoming wire fee depending on the account type and institution.

Account / Platform Fee

Some business payment platforms charge monthly or account-related fees, which matter more as payment volume grows.

Total Cost Formula

Total transfer cost = FX cost + transfer fee + intermediary fees + receiving fees + other applicable charges

What Information Do You Need to Send Money to the US?

For a US bank transfer, businesses may need the details below. Requirements vary by provider and transaction.

Recipient Information

• Full legal name
• Company name where applicable
• US bank account number
• ABA routing number
• Account type
• Bank name
• Bank address where required

For SWIFT Transfers

• SWIFT / BIC
• Recipient bank information
• Payment purpose
• OUR / SHA / BEN preference where applicable

For Business Transfers

Providers may also request:

• invoice
• contract
• business registration information
• source-of-funds information
• payment purpose

How to Choose a US Money Transfer Method for Your Business

Consider these factors when matching a rail to your payment pattern.

Payment Frequency

One large payment is different from 100 recurring supplier payments. Recurring flows favour ACH or a platform with batch capability.

Payment Amount

Large transactions may require different rails, limits, or compliance documentation.

Currency

If you already hold USD, avoid unnecessary HKD → USD conversion by paying from a USD balance.

Recipient's Bank

Check whether the recipient accepts:

• ACH
• domestic wire
• international wire
• other supported payment methods

Total Cost

Compare the full cost, not just the advertised transfer fee. FX spread and intermediary fees can dominate.

Settlement Time

Consider whether the supplier needs funds on a specific date, and whether cut-off times or holidays will interfere.

Business Controls

For teams, look for:

• approval workflows
• user permissions
• batch payments
• transaction tracking
• reconciliation
• API support

Common Mistakes When Sending Money to the US

• Using SWIFT for every US payment. A local ACH route may be available for eligible recurring USD payments and can be cheaper.
• Converting HKD to USD for every transaction. Businesses with regular USD expenses may benefit from holding USD in a USD business account in Hong Kong.
• Looking only at transfer fees. FX spread and intermediary fees can have a larger impact on total cost than the headline fee.
• Entering the wrong routing number. US ACH and wire routing details may differ; a mismatch can delay or bounce the payment.
• Ignoring payment purpose. Business transfers may require invoices, contracts, or other supporting information.
• Assuming ACH is available everywhere. ACH is a US domestic rail. Access for a Hong Kong business depends on the provider and account structure.

FAQs About Sending Money from Hong Kong to the US

What is the cheapest way to send money from Hong Kong to the US?

There is no single cheapest method for every payment. SWIFT wires often carry a transfer fee plus an FX spread and possible intermediary and receiving fees, so the total can be high. For recurring USD payments where the recipient accepts US local rails, ACH through a payment platform is often lower cost because it avoids some correspondent-bank fees. The reliable way to compare is to calculate the full cost — FX spread plus all fees — not the advertised transfer fee alone.

Can a Hong Kong business send money to a US supplier by ACH?

ACH is a US domestic rail, so a Hong Kong business does not send ACH directly from a local bank in most cases. The practical route is to use a business payment platform or provider that can access US local payment rails, then push USD to the supplier's US bank account using their account number and ABA routing number. Whether ACH is available depends on the provider, the recipient's bank, and the transaction type.

How long does it take to transfer money from Hong Kong to the US?

Timing depends on the rail. ACH through a connected platform is often settled within one to several business days, subject to provider and compliance checks. SWIFT wires typically take several business days once cut-off times, correspondent banks, and holidays are factored in. Stablecoin settlement can be faster but depends on the blockchain network and the recipient's ability to off-ramp to USD. Avoid assuming "instant" unless a specific provider guarantees it.

Can businesses pay US recipients with USDC or USDT?

For eligible business transactions where the recipient accepts stablecoins, USDC or USDT can be sent to the recipient's wallet as a settlement option, after which they may hold or convert to USD. This is not a universal replacement for ACH or bank wires — it depends on the recipient's preference, jurisdiction, compliance requirements, and off-ramp access. Stablecoins are a settlement and optimisation option, not a speculation product, and should be evaluated against the same cost, speed, and control criteria as any other rail.

Bottom Line

Hong Kong businesses can send money to the US through SWIFT, US local ACH via a connected platform, or a multi-currency business payment platform — and the best choice depends on frequency, amount, whether you already hold USD, and the full cost rather than the headline fee. For recurring USD payments, holding USD and using ACH-style local rails usually beats sending a SWIFT wire each time.

PhotonPay brings holding, conversion, multi-asset business cards, and global payouts into one next-generation payment operating system, with supported USDC and USDT balances available where a business wants to fund payments with stablecoins.
