Verified — I’ve held a Boom account since 2007. Coverage based on long-term personal use plus Boom’s published market list and broker materials.
What it is
Hong Kong-based brokerage founded 1997 (formerly Monex Boom Securities), acquired by Ignition Holdings in June 2024. The structural differentiator is 18 global markets through a single onboarding — broader Asian coverage than the modern fintech brokers (Tiger, Futu/moomoo) that focus on 4–5 markets. Core coverage includes Hong Kong, Mainland China A-shares (Stock Connect framework), Japan, Singapore, South Korea, Taiwan, United States, and Australia — plus the harder-to-reach Southeast Asian markets: Indonesia (IDX), Philippines (PSE), Malaysia (Bursa Malaysia), and Thailand (SET). That last group is where Boom earns its place; most international brokers don’t cover Indonesia or Philippines from outside the country.
My status with this broker
Verified — I’ve held a Boom account since 2007, so this is nearly two decades of first-hand experience. It’s widely regarded as one of the best Asian retail brokers for international investors, thanks to broad market access through a single Hong Kong account, and that matches my own long-term use.
Who it’s for (and who should skip)
Use Boom when:
- You want exposure across multiple Asian markets — including Indonesia, Philippines, Malaysia, Thailand — without maintaining 4–5 separate broker accounts.
- You’re a buy-and-hold investor where execution-time precision matters less than market access.
- Broad Asian multi-market coverage is the priority over platform aesthetics.
Skip Boom when:
- Your Asian exposure is limited to Hong Kong, Singapore, US, or China — Tiger or Futu/moomoo offer cheaper commissions and better apps for those markets.
- You want active trading with a modern mobile-first UX.
- Your primary need is Western or global developed markets — IBKR is the answer there.
Account-opening friction
Account opening is broker-mediated rather than fully self-service — closer to a traditional brokerage relationship than the Tiger/Futu app-only model. Standard documentation applies: passport, proof of address, source of funds. Settlement is available in 6 currencies (HKD, SGD, USD, JPY among them), allowing you to hold balances across currencies without forcing constant FX conversions for each Asian market traded.
Platform UX is older than the modern fintech brokers. Tiger and Futu built their interfaces in the smartphone era; Boom’s predates that wave and feels more traditional. Worth confirming the exact current 18-market list directly with Boom at the time of onboarding, as coverage details can change after acquisition.
Known caveats
- Acquisition uncertainty. Ignition Holdings completed the acquisition in June 2024; any strategic repositioning post-acquisition could affect market coverage or fee structure. Confirm current offering before committing.
- Fees. Not exorbitant, but higher than IBKR — and it charges fees on dividends, which is an annoyance for buy-and-hold holders.
- Deposit/withdrawal friction. Still a little clunky (deposits historically required faxes); workable, but not the frictionless app experience.
- Platform age. For readers used to Tiger or Futu, the UX gap is real. For passive, buy-and-hold positioning it is largely irrelevant.
Verdict
Boom long provided access to markets that were genuinely hard to reach otherwise — South Korea, the Philippines, Malaysia, Indonesia, Thailand and mainland China — through a single Hong Kong account. It’s a web-1.0-era broker that has largely stayed there (a good web-1.0 interface, to be fair); deposits once required faxes, and there’s still a bit of friction on deposits and withdrawals. Fees aren’t exorbitant but they’re higher than IBKR, and it annoyingly charges fees on dividends. Its edge has narrowed now that IBKR and others have expanded their Asian coverage. I’ve been a happy Boom user for years — but where IBKR and Boom offer the same market, I now choose IBKR.
