The short answer
For most Malaysians, the cheapest normal way to fund Interactive Brokers is still Wise. You get the mid-market rate, pay a transparent variable convert fee of about 0.61% on MYR to USD right now, then send the USD into IBKR.
Local bank telegraphic transfer is simpler for some people, but the board FX rate usually loses to Wise by about 1% on the same day. That gap compounds if you fund every month for years.
If you need to move more than Wise will let you hold at once, that is a different problem. Personal Wise accounts in Malaysia are capped at RM20,000 equivalent across currencies. Working-class DCA almost never hits that. Six-figure lumps do. For those, either split across a few days, or use a multi-currency bank path such as Maybank Global Access. I documented a real large transfer in a separate post linked below.
I am not promoting Wise. I do not have a Wise referral link. I am comparing what Malaysians actually use.

Why funding cost matters
Most people underperform the market because they ignore costs. Fund TER, withholding tax, and FX all work against you.
That is why I care about the tax edge of Irish-domiciled ETFs, and why this post exists. Funding is often the first cost you pay, before a single share is bought.
A rough rule I use: keep each deposit's all-in funding cost under about half a month of expected market return. If you treat long-run US equity as roughly 12% a year, half a month is about 0.5%. That is a personal threshold, not a law. When you cannot accumulate enough in a few months, accepting closer to 1% can still beat sitting in cash for half a year.
Funding size, frequency and opportunity cost
Most methods mix a percentage fee and a fixed fee.
Person A sends RM2,000 every month. Person B saves the same RM2,000 a month and sends RM24,000 once a year. Person B usually pays less in fixed fees. Person A is invested earlier.
Who wins depends on market returns and what B earned on cash while waiting. There is no single best frequency. I try to fund when the all-in cost is near my 0.5% rule, and I do not wait years to save a tenth of a percent.
How Malaysians actually fund IBKR
IBKR does not hold MYR natively. Official guidance is to deposit a supported currency (USD, EUR, and others). For Malaysia, the documented local path is the Wise partner flow: MYR funding reference and Transfer from Wise Balance.
IBKR itself generally does not charge a deposit fee for normal wires or Wise deposits. Your bank, Wise, and any intermediary bank can still charge. See IBKR fund your account.
1. Wise (default for most people)
Wise is listed by Bank Negara as an e-money issuer. Unlike most banks, it shows the mid-market rate and a separate fee instead of burying the cost in a worse board rate (Wise mid-market rate).
Convert fee (MYR to USD in Wise), my quotes on 2026-07-26:
| Convert | USD you get (approx.) | Variable fee | Fee as % of MYR |
|---|---|---|---|
| RM1,000 | US$242.97 | RM6.07 | 0.61% |
| RM5,000 | US$1,214.86 | RM30.31 | 0.61% |
| RM10,000 | US$2,429.72 | RM60.63 | 0.61% |
| RM20,000 | US$4,859.44 | RM121.26 | 0.61% |
That is why a table is still useful even when the exchange rate moves every minute. On this corridor the variable convert fee is a stable percentage of the MYR amount (about 0.61% in my quotes). The mid-market rate changes. The fee percentage barely did across RM1k to RM20k.
On top of conversion, sending USD from Wise Balance into IBKR still has a small fixed fee on the order of about US$1. That fixed piece matters more on tiny deposits than on large ones:
- About US$1 on US$243 ≈ 0.4% extra
- About US$1 on US$2,430 ≈ 0.04% extra
So all-in for a typical RM5k-RM10k convert + USD send is roughly 0.65%, still in the same ballpark as the old post, and still usually cheaper than retail bank TT FX.
Limits that actually bite:
- Personal Wise accounts registered in Malaysia cannot hold more than RM20,000 equivalent across all currencies (Wise holding limits).
- Sending is capped separately at RM30,000 per day for MYR converted or sent abroad, and there is a third limit that catches people out at size: 13 cross-currency transfers per month, to a maximum of 7 recipients (Wise MYR transfer guide). That count is the real ceiling. RM400,000 would need 14 transfers, so it does not fit inside one calendar month at all.
- Transfers from Wise back to your own Malaysian bank account have no daily limit. Money coming home is easy. It is money going out that is capped.
What to do if you are over the limit:
- Split across a few days if timing does not matter.
- For a true lump sum, use a bank multi-currency path (see Maybank Global Access below) instead of ten Wise hops.
IBKR deposit UI when USD is selected. Always follow the live Client Portal labels.
EUR path (optional, not required):
Some people convert MYR to EUR in Wise, transfer EUR to IBKR (send fee has often been free or cheaper than USD), then buy USD assets and let IBKR auto-convert. IBKR auto FX is typically about 0.03%. Manual IDEALPRO spot FX is 0.20 bps (0.002%) with a US$2 minimum on Tier I (IBKR spot currency commissions).
I do not optimise hard for the EUR route anymore. On normal sizes the USD path is simple enough, and the gain is small once the fixed USD send fee is spread out. If you use a margin account, multi-currency balances can also be treated as collateral, which is easy to get wrong. Cash accounts are simpler.
2. Bank telegraphic transfer (wire)
Classic path: create a deposit notification in IBKR, then send a USD TT from Maybank, CIMB, HSBC, and so on.
Published online service fees (not including FX):
| Bank | Online outward TT service fee | Source |
|---|---|---|
| Maybank | RM10 (SST may apply on fees) | Maybank FTT |
| CIMB | RM10 | CIMB Clicks fees |
| HSBC | RM25 | HSBC international transfer |
The expensive part is usually the FX board rate, not the RM10. On the same day, retail bank sell rates for USD often sit roughly 1% worse than Wise all-in. Preferred or private-banking clients sometimes do better. Very large transfers can sometimes be negotiated.
CIMB is worth a same-day check. I will not pretend I re-ran a full fee lab here, but CIMB's TT rate is not always the same lazy board rate as every other bank. On some days it is merely average. On others it is competitive enough that the all-in can beat, or nearly beat, Wise once you include Wise's convert fee and the small USD send fee. Open MAE/Maybank, CIMB, and Wise side by side before a big send. For normal monthly DCA under the Wise limit, I still default to Wise without shopping every bank.
For ordinary DCA, Wise still usually wins. For lumps near or above the Wise hold limit, compare Wise splits, CIMB TT, and Maybank Global Access on the day you move the money.
If you choose SHA (shared charges), intermediary banks may skim the wire. OUR / full-amount options cost more upfront but can protect what IBKR receives.
Always:
- Create a fresh deposit notification in IBKR for the right currency.
- Copy the currency-specific bank details exactly.
- Send only from an account in your name. Third-party deposits are usually rejected.
- Budget time for matching and possible holds.
3. Maybank Global Access for large amounts
Wise's hold limit is the hard constraint for big lumps. Splitting a six-figure transfer into many Wise days works, but it is slow if you need the cash invested now.
Maybank Global Access is a multi-currency account. Outward USD fixed fees are much higher than Wise's small send fee (on the order of US$22 vs roughly US$1 in the GAA review). The question is whether the FX rate on one large transfer is good enough to offset that.
I walked through a real Global Access → IBKR example, with screenshots, here:
Maybank Global Access vs Wise: full review and fee breakdown
On that RM100k test, GAA cost about 0.27% more than Wise, roughly US$62 extra. Most of that was worse FX plus the fat fixed TT fee.
One update since then: Wise's own convert fee has moved up. In this post it is about 0.61%, versus about 0.54% when I first wrote the funding guide. That does not flip the ranking. Wise is still usually cheaper for normal sizes. It does shrink the convert gap, so on a large GAA transfer the all-in disadvantage is probably closer to something like ~0.1% than 0.27%, if Maybank's FX is still around the old ~0.62% mid markup. I have not re-run a full same-day GAA quote, so treat that as direction, not a new lab result. The fixed US$22 vs ~US$1 fee still sits on every GAA TT.
Use the GAA post for the large-lump decision and the messy app UX. Use this post for the overall ranking and the DCA math.
4. Higher-friction options
- Other fintech ACH-style deposits: quote-driven. Create IBKR deposit details first, then compare all-in vs Wise the same day.
- Wise → Singapore bank → IBKR: more steps and more FX legs. Not my default.
- Withdrawals are different. Taking money out via SGD to CIMB Singapore is a common low-cost exit path. Do not mix withdrawal math into funding comparisons.
Is Wise always cheapest?
For normal recurring funding under the Wise hold limit, yes. Wise is still the default I would use, even after the convert fee drifted up toward 0.61%.
For very large one-off transfers, compare on the same day:
- Live Wise quote if you can stay under the limit or split cleanly
- Live bank TT rates (CIMB included, not only Maybank) + fixed fee + intermediary risk
- Maybank Global Access all-in on a real quote
The GAA path is rarely "cheaper than Wise." In my measured example it was more expensive. The case for GAA is speed and not babysitting a multi-day Wise split. Include time. If you need cash in IBKR this week to buy a dip, paying an extra tenth of a percent or so can be rational.
Risk note
Money and securities at IBKR are not protected by PIDM. PIDM covers eligible deposits at Malaysian member banks. IBKR LLC client assets fall under US SIPC (and excess SIPC), not Malaysian deposit insurance. IBKR is also not SC-licensed in Malaysia. Using a foreign broker is normal for many investors, but your protection and complaint path are different. More in the IBKR Malaysia guide.
Practical checklist
- IBKR Client Portal → Transfer & Pay → Deposit.
- Prefer the Wise integration for ordinary sizes. Follow the flow IBKR shows.
- Keep each deposit's all-in cost near your personal threshold (I use ~0.5% as a guide).
- After money arrives, buy what you planned. For me that is often Irish-domiciled ETFs.
- Still choosing a broker? Read Moomoo vs IBKR for Malaysians before you optimise funding for the wrong account.
Closing
Funding IBKR from Malaysia is mostly an FX problem. Pay less on conversion, avoid third-party deposits, and do not let a 0.6% fee become a reason to stay uninvested for a year.
What are you using to fund IBKR right now, and what all-in % did you see on your last transfer? If you have a method that beats Wise on a normal RM5k-RM10k send, leave the fee breakdown in the comments.
