Moomoo Margin Interest Rate in Singapore (2026 Guide)

The real 2026 numbers on moomoo’s margin financing rates — plus how they stack up against IBKR and Tiger Brokers.

Moomoo Singapore charges 4.8% per annum on SGD and USD margin loans, higher for HKD (6.8%) and lower for JPY (3.8%), as at July 2026. That’s more expensive than Tiger Brokers’ 2.8% SGD rate and Interactive Brokers’ tiered rates starting at 2.624%, though moomoo can beat both on USD margin for smaller loan sizes. Here’s exactly how the numbers work.

What Is Margin Financing on Moomoo?

A margin account lets you borrow money from your broker, using the cash and shares already in your account as collateral, to buy more stocks or ETFs than your own cash would allow. Moomoo Financial Singapore Pte. Ltd. offers margin accounts to retail clients under its Capital Markets Services Licence from the Monetary Authority of Singapore (MAS), alongside its regular cash accounts.

You don’t have to apply for margin trading — it’s usually enabled as an option on your existing moomoo account, subject to a suitability check. Once enabled, your “buying power” in the app expands beyond your cash balance, and any amount you borrow above your own funds starts accruing interest immediately, whether or not the position moves in your favour.

The catch: margin is a loan, not free extra capital. You’re paying an annual interest rate on the borrowed amount, and if your holdings fall enough, moomoo can sell your positions without asking first. That’s why understanding the actual interest rate — and how it compares across brokers — matters before you switch on margin.

Moomoo Margin Interest Rates in Singapore (2026)

Moomoo publishes flat annual interest rates by currency on its official SG pricing page. As at 18 July 2026, these are the rates:

Notice there’s no tiered structure here. Whether you borrow SGD 5,000 or SGD 500,000, you pay the same 4.8% per annum on SGD and USD balances. Moomoo itself notes the rate “varies according to daily market supply,” so treat 4.8% as the current indicative rate and always check your monthly statement for the exact figure applied to your account.

How Moomoo Calculates and Charges Margin Interest

Interest accrues daily on your outstanding debit balance — the amount you’ve actually borrowed, not your total position size. The formula is straightforward:

Daily interest = Debit balance × (Annual rate ÷ 365)

Moomoo adds up each day’s charge over the month, then deducts the total from your account in one lump sum. That means paying down your loan partway through the month genuinely reduces the interest you owe — it’s not charged as a flat monthly fee regardless of balance. Interest keeps accruing even on weekends and public holidays, since it’s a calendar-day calculation, not a trading-day one.

Real Cost Example: Borrowing SGD 20,000 on Margin

Numbers are easier to judge with a concrete example. Say you top up your own capital with a SGD 20,000 margin loan for a full year, and the rate stays flat at 4.8%:

SGD 20,000 × 4.8% = SGD 960 per year in interest, or about SGD 80 a month — before your position has even moved. Your investment needs to clear that hurdle just to break even on the borrowed portion.

Compare that to Tiger Brokers’ 2.8% SGD rate: the same SGD 20,000 loan costs SGD 560 a year — SGD 400 less than moomoo. At Interactive Brokers’ entry-tier Pro rate of 2.624% (for the first S$140,000 borrowed), the same loan costs SGD 524.80 a year, SGD 435.20 less than moomoo. For a Singapore investor running this size of margin position over several years, that gap compounds.

Moomoo vs IBKR vs Tiger Brokers: Margin Rate Comparison

The full picture depends on currency, not just which broker “wins.” Here’s how the three brokers compare on their published SGD and USD margin rates as at 18 July 2026:

The nuance most comparison articles miss: moomoo isn’t uniformly the most expensive. For a SGD loan, it’s the priciest of the three — Tiger and IBKR Pro both undercut it by two full percentage points or more. But flip to USD, and moomoo’s flat 4.8% is actually cheaper than IBKR Pro’s smallest tier (5.13% for loans under US$100,000) and well below Tiger’s 6.5%. If you mainly trade US stocks and ETFs on margin with a moderate balance, moomoo’s simplicity can work in your favour — you’re not penalised for having a smaller account the way IBKR Lite or Tiger effectively can be at some tiers.

Where moomoo loses ground is scale. IBKR’s tiered structure means a Singapore investor running a S$500,000+ margin book pays meaningfully less per dollar borrowed as the balance grows. Moomoo offers no such discount — the 4.8% rate applies whether you’re borrowing SGD 5,000 or SGD 5,000,000.

How to Enable Margin Trading on Moomoo Singapore

If you’ve decided margin suits your strategy, here’s the general process on moomoo SG:

1. Open or log in to your moomoo account. You need an existing cash account before margin can be added.

2. Apply for margin trading. In the app, go to your account settings and look for the margin or “buying power” upgrade option. You’ll need to complete a risk disclosure and suitability assessment, since MAS requires brokers to check that margin trading matches your investment experience and risk tolerance.

3. Fund or transfer in your collateral. Your existing cash and marginable securities become the collateral base. Not every counter is marginable — moomoo assigns a margin ratio to each stock or ETF, and some counters (illiquid small caps, for instance) may not qualify at all.

4. Check your margin ratio before trading. The app shows your available buying power and current margin ratio. Borrowing right up to the limit leaves almost no buffer before a margin call.

5. Place your trade using margin buying power. Any amount spent beyond your own cash balance becomes a margin loan and starts accruing interest from that day.

Risks of Margin Trading You Need to Know

Margin financing isn’t just “more expensive investing” — it changes the risk profile of your entire portfolio:

Margin calls and forced liquidation. If your margin ratio drops below moomoo’s maintenance requirement — because your holdings fall in value — you’ll get a margin call. Miss it, and moomoo can sell your positions to restore the required ratio, often at the worst possible time and without further warning.

Leverage cuts both ways. A 10% market drop on a fully margined position can wipe out a much larger share of your own capital, since your equity is smaller than the position size. Leverage amplifies losses exactly as it amplifies gains.

Interest accrues regardless of performance. The 4.8% clock keeps ticking whether your position is up, flat, or down. A sideways market still costs you real money in interest.

Marginability can change. Moomoo can adjust which counters are marginable and at what ratio, sometimes with little notice, which can shrink your buying power or trigger a call even if you haven’t traded.

Who Should (and Shouldn’t) Use Moomoo Margin Financing

Margin on moomoo may suit you if: you have an established, diversified portfolio and understand margin mechanics; you’re borrowing predominantly in USD for smaller balances where moomoo’s flat 4.8% beats IBKR Lite or Tiger; you have a clear exit plan and can meet a margin call in cash within a day; and you treat the interest cost as a real, ongoing expense in your return calculations, not an afterthought.

Consider alternatives — or skip margin entirely — if: you’re a beginner investor still building conviction in your strategy; you’re borrowing mainly in SGD, where Tiger Brokers or IBKR are meaningfully cheaper; you’re running a large margin balance, where IBKR’s tiered pricing saves real money at scale; or you don’t have a buffer of liquid cash to cover a sudden margin call. For most Singapore investors focused on long-term investing rather than active trading, building your retirement portfolio with unleveraged cash contributions remains the lower-risk path.
