These products both convert currency but serve different accounts. Interactive Brokers offers spot FX for investing, trading or hedging activity inside a funded brokerage. Currenxie is a business payments platform with published currency tiers and a global account. The IBKR commission model can rank lower once its minimum is small relative to the amount, but it does not include execution or withdrawal.
On a $10,000 dollar-to-euro conversion, the IBKR commission model costs about $2.00, while Currenxie costs about $35.00 with a modelled markup of about 0.35% on major currencies. A $10,000 IBKR USD order is an odd lot, and the row excludes its live spread, slippage and withdrawal path.
- IBKR has the lower fee model at larger amounts. Its Tier I commission is 0.002%, with a USD 2 equivalent minimum per order.
- On very small amounts, Currenxie can win. IBKR's USD 2 equivalent minimum costs more than Currenxie's percentage below roughly $500.
- Currenxie is transparent and business-focused. Clear tiered markups, a free global account, and no separate fee.
- IBKR needs a funded brokerage account. Convert Currency submits a market order, and small orders can face a wider odd-lot spread.
How Interactive Brokers charges
Interactive Brokers (IBKR) charges a Tier I spot-FX commission of 0.20 basis points (0.002%) of trade value, with a USD 2 equivalent minimum per order. Convert Currency submits a market order, so the executable bid/ask spread and slippage affect the result.
The commission minimum explains the modelled crossover, but it is not the full cost. IBKR's standard USD order range begins at USD 25,000. Smaller orders are odd lots and can execute at a wider spread. You also need a funded eligible account, a supported direct pair and a separate eligible withdrawal if the converted cash must leave the brokerage.
How Currenxie charges
Currenxie is a business FX platform built around transparency. It offers a free multi-currency global account and converts at the mid-market rate plus a published markup that varies by currency: about 0.35% on major pairs (dollars, euros, pounds and the like), 0.10% on USD/HKD, and up to 0.60% on emerging-market pairs. There is no separate conversion fee.
The appeal is that you can see the margin before you commit, and it is the same every time for a given pair. There is no commission floor to work around, so on a small conversion Currenxie's percentage can beat IBKR's USD 2 equivalent minimum. The platform is aimed at businesses holding and moving money across borders.
Head to head, by amount
The fee model flips with size because IBKR has a commission minimum and Currenxie has a percentage. Here is the same conversion at three sizes, all below IBKR's standard USD minimum.
$100: the floor bites
At $100, IBKR's USD 2 equivalent minimum is 2% of the transfer, while Currenxie's modelled 0.35% is about 35 cents. Currenxie ranks first even before considering IBKR's odd-lot execution and brokerage workflow.
$1,000: they cross over
At $1,000, the model puts IBKR's minimum below Currenxie's percentage. The displayed crossover is not a guaranteed executable crossover because the IBKR order is an odd lot and the table omits its spread and withdrawal.
$10,000: IBKR well ahead
At $10,000, the modelled IBKR commission remains at the USD 2 equivalent minimum while Currenxie's percentage scales. The IBKR order remains an odd lot, so check the live order preview.
The pattern at a glance
The bars show the stored fee model. They do not include IBKR's buying-versus-selling price difference, slippage, tax, withdrawal or third-party-bank charges.
The savings in context
Across the displayed estimates, choosing Interactive Brokers over MoneyGram leaves an extra €326.11 (3.93%) in the recipient's account.
Same 10,000 USD and the same market rate before fees. Provider availability, how you pay and the final price can change the result.
Who should pick what
Check Interactive Brokers first when the conversion is part of an eligible investment, trade or currency hedge in that account. Confirm the rate you can actually trade at rather than relying on the commission crossover alone.
Pick Currenxie if you make smaller conversions, you value seeing the exact margin up front, or you want a business FX platform with a free global account and no commission floor to think about. Its tiered pricing is transparent and steady.
Pick a transfer specialist if the job is a simple send into a bank account rather than a conversion you manage yourself. A provider like Wise is built for that and is smoother than a broker for a one-off payment. See Wise vs Currenxie and Wise vs Interactive Brokers.
The bottom line
The model puts Currenxie first on a very small conversion and IBKR first once its commission minimum becomes the smaller percentage. IBKR is relevant when the exchange supports investing, trading or hedging in the brokerage; Currenxie supplies the business account and payment workflow.
Currenxie's strength is its tiered pricing and business payment platform. IBKR's strength is its extremely low commission when currency exchange supports brokerage investing, trading or hedging. Our markup versus fee guide shows how to compare the rate as well as the visible charge.
Frequently asked questions
Is Interactive Brokers cheaper than Currenxie?
IBKR ranks lower above the modelled fee crossover, while Currenxie ranks lower on the smallest example. The real crossover can move because IBKR odd lots have a buying-versus-selling price difference and the row excludes withdrawal costs.
What is Currenxie best for?
Transparent, business-focused FX. Currenxie publishes its markup in clear tiers (about 0.35% on majors, less on USD/HKD, more on emerging pairs), charges no separate fee, and offers a free multi-currency global account. It is a good fit for businesses that want to see exactly what they pay.
Do I need a brokerage account to use Interactive Brokers?
Yes. You need a funded eligible IBKR account. Convert Currency submits a market order, and moving cash out requires an eligible withdrawal. Third-party payees require approval and due diligence.
