Endowus lets you invest your CPF-OA, SRS, and cash into low-cost, institutional-class funds, while GXS Bank’s Boost Pockets pay up to 1.6% p.a. on cash you can’t afford to risk. Together, they cover both jobs: growing your long-term retirement money and protecting your emergency fund with SDIC-insured interest. Neither platform does both jobs well alone.

What Is Endowus, and What Is It Good For?

Endowus is a Monetary Authority of Singapore (MAS)-licensed robo-advisor and fund platform. It gives you access to institutional-class unit trusts from managers like Dimensional, PIMCO, and Fullerton — funds that used to be reserved for private banking clients — at a fraction of the typical bank platform fee.

You would open Endowus if you want your CPF Ordinary Account (CPF-OA) or Supplementary Retirement Scheme (SRS) money to grow beyond the CPF-OA’s 2.5% floor rate or a bank’s near-zero SRS interest. You can sign up with the Endowus referral code and sign-up bonus using code 2V343.

However, Endowus’s fund portfolios and Cash Smart products are market-linked, not guaranteed, and not SDIC-insured. That’s exactly why they shouldn’t be your only home for cash you might need on short notice.

What Is GXS Bank, and What Is It Good For?

GXS Bank is a full digital bank in Singapore, backed by Grab and Singtel, and regulated by MAS. Rate details are published on the GXS Savings Account page. Deposits are SDIC-insured up to S$100,000 per depositor — the same protection as a traditional bank.

Your GXS Main Account earns 0.88% p.a. daily interest with no minimum balance or salary crediting required. Where GXS really stands out is Boost Pockets — sub-accounts that pay up to 1.6% p.a. for a fixed tenure of 1, 3, 4, 8, or 12 months, across up to five pockets and a combined S$95,000 deposit limit.

Because it’s SDIC-insured with a locked-in rate for the tenure you pick, GXS is the better home for money you can’t afford to see fluctuate — your emergency fund, or cash you’ll need on a known date. You can find sign-up details on the GXS Bank referral code page.

Why Combine Them Instead of Using Just One

Here’s the mistake many Singaporeans make: they pick one platform and force all their money into it. That’s a problem because Endowus and GXS are built for different jobs.

Endowus’s CPF-OA and SRS portfolios need time to compound. They can dip in value in a bad quarter, which is fine if you won’t touch the money for 5-10 years. However, that volatility makes Endowus a poor place for your emergency fund. If you needed to withdraw during a downturn, you’d lock in a loss.

GXS, on the other hand, gives you a fixed, SDIC-insured rate. That’s perfect for money you need to protect, but its ceiling of 1.6% p.a. won’t build real long-term wealth the way a properly invested CPF-OA or SRS portfolio can.

For example, a Singapore investor with S$30,000 in CPF-OA sitting idle earns a flat 2.5% p.a. from CPF. Moving part of that into an Endowus CPF-OA portfolio targets higher long-term returns, while keeping 3-6 months of expenses in a GXS Boost Pocket protects you from having to sell investments in an emergency.

Rate and Fee Comparison: Endowus vs GXS Bank

What This Actually Means in Dollars

Numbers on a rate sheet don’t mean much until you see them applied to real amounts. Here’s how S$10,000 in cash performs across a year, and how S$30,000 in CPF-OA compares over five years if part of it were invested through Endowus.

Source: TKN calculation based on published rates, August 2026. For illustration only, not guaranteed returns.

Over 5 years, a S$30,000 CPF-OA balance left untouched grows to roughly S$33,942 at the guaranteed 2.5% p.a. If a portion were instead invested through Endowus at a hypothetical average of 5% p.a. — well within the historical range of a balanced portfolio, though never guaranteed — that same S$30,000 could grow to roughly S$38,288, a difference of about S$4,346. Markets can also underperform this assumption in any given stretch.

The August 2026 GXS SG61 Boost Pocket Promo

Right now, GXS is running a National Day-themed promo called “SG61”. If you deposit into a 12-month Boost Pocket named SG61, GXS pays you S$10 cashback for every S$10,000 you deposit. The promo is valid until 18 August 2026.

For example, if you moved S$50,000 into an SG61 Boost Pocket before the deadline, you’d receive S$50 cashback on top of the 1.6% p.a. interest for the 12-month tenure. That’s a meaningful boost if you already have emergency fund cash sitting idle in a low-interest account instead of being invested through Endowus.

However, don’t chase a promo with money you might need before the 12-month tenure ends. Boost Pockets lock in a rate for the full term, so early withdrawal can mean forfeiting the bonus interest.

How to Set Up the Combo, Step by Step

1. Work out your emergency fund target — typically 3-6 months of essential expenses.

2. Open a GXS Bank account and move your emergency fund into a Boost Pocket. If it’s before 18 August 2026, consider naming a 12-month pocket “SG61” to capture the cashback.

3. Sign up for Endowus separately using referral code 2V343. You’ll need Singpass MyInfo and your CPF/SRS account details if you’re investing those.

4. Decide how much CPF-OA and SRS you’re comfortable investing beyond your near-term needs, and pick a fund tier or ready-made portfolio that matches your risk appetite.

5. Review both accounts every 6-12 months. Rates on both platforms move with the broader rate environment, so today’s numbers won’t be permanent.

Risks and Things to Watch

Endowus’s fund portfolios and Cash Smart products are not principal-guaranteed. They invest in unit trusts, money market and short-duration bond funds, and while losses are historically rare for cash-like funds, they’re not impossible — especially during sharp rate moves.

Investing CPF-OA or SRS money through Endowus means giving up the CPF-OA’s guaranteed 2.5% interest for as long as it’s invested — a real trade-off, not a free upgrade.

GXS Boost Pockets are SDIC-insured up to S$100,000 combined per depositor, per bank, but locking cash into a fixed tenure means you can’t access it early without losing the bonus interest.

Rates and fees on both platforms are variable and can change. The figures in this article are accurate as at August 2026 — always check the live rate on each platform before committing new money. Neither Endowus nor GXS should hold 100% of your money; this combo works because it splits risk and time horizon across two purpose-built tools.
