You have just landed a large sum. Maybe a property sale completed, an inheritance cleared probate, a business paid out, or you simply saved hard and the number finally crossed six figures. Now €100,000 or more is sitting in your current account, earning almost nothing, and you are not ready to commit it. You want to invest it properly, but you need weeks or months to decide how, and in the meantime you do not want it exposed to a market drop or quietly losing value in a zero-interest account.
Here is the honest answer up front: parking is not investing, and you should not treat it as such. The job of parked cash is capital preservation with a modest, near-risk-free yield, plus enough liquidity to pull the money out the day you commit to a plan. That rules out equity ETFs entirely. What is left is a short, sensible list — money market ETFs, short-dated government bond ETFs, and bank term deposits — each with its own trade-off between yield, liquidity and safety.
I have parked large lumps twice in the last decade, once after selling a flat and once ahead of a phased deployment. Below is exactly how I think about it, and what I would actually do with €100,000+ today.

The mistake I see most often is conflating two decisions. Decision one is where the cash sits safely while you think. Decision two is how you move it into the market. They are different problems and you solve them in that order.
For decision one, your only real criteria are: will I get virtually all of it back, can I access it quickly, and does it earn something close to the central bank rate rather than nothing. You are not trying to grow wealth here, only to avoid losing ground. Chasing an extra 0.5% of yield by taking on duration or credit risk defeats the purpose; if the parked money can fall 4% before you have even started, it was never really parked.
For decision two, once you have a target portfolio, you choose between a lump-sum move and phasing in over several months. How you plan to deploy changes which parking vehicle suits you best.
Option 1: Money market ETFs
For most people with a brokerage account, a euro money market UCITS ETF is the cleanest parking spot. These funds hold very short-dated, high-quality instruments and track something close to the euro short-term rate (€STR). When the central bank rate is meaningfully positive, they yield roughly that rate minus a small fee. The TER on the well-known ones is low, typically around 0.10–0.12% (treat that as approximate and confirm on the current factsheet).
This analysis sits within our defensive UCITS hub.
The appeal is simple. Interest-rate sensitivity is minimal because the underlying instruments mature in days, so the price barely moves. You can sell during market hours and have cash back in the normal settlement window. And it sits in the same account you will eventually invest from, so deploying later is a single internal trade.
Two honest caveats. First, a money market ETF is a fund, not a deposit, so it is not covered by any deposit-guarantee scheme. Its safety comes from the quality and short maturity of what it holds, which is genuinely high, but it is not a government guarantee. Second, the yield follows the central bank down; if rates are cut while you are parked, your return drops too. For a holding period of weeks to a few months, both caveats are minor.
Option 2: Short-dated government bond ETFs
A step along from money market funds are short-term government bond ETFs, holding say 0–1 year or 1–3 year euro-area government paper. These can offer a slightly higher yield, but you take on a little more interest-rate risk: if yields rise, the fund’s price dips. Over a genuinely short parking window the 0–1 year bucket behaves almost like cash; the 1–3 year bucket can wobble a percent or two, which matters if you might deploy on short notice.
If you want to understand the category properly first, I have a fuller breakdown of short-term bond ETFs and when they make sense, and a companion piece on cash versus short-term bond ETFs. For a six-figure lump you plan to move soon, I lean toward the shortest maturities or a money market fund; the extra yield from stretching duration is rarely worth the risk of being forced to sell at a small loss.
Option 3: Bank term deposits and the €100,000 guarantee
The vehicle most people already understand is a bank deposit. Fixed-term deposits can pay a competitive rate, and crucially they carry the statutory deposit guarantee. Across the EU, eligible deposits are protected up to €100,000 per person, per bank, under the harmonised Deposit Guarantee Schemes framework. You can find your national scheme via the European Banking Authority’s deposit guarantee schemes pages.
That €100,000 ceiling is the key detail when your sum is larger. If you park €180,000 at a single bank, only €100,000 is guaranteed; the rest ranks as an ordinary claim if that bank fails. The fix is boring but effective: spread the money across two or three separate licensed banks so each tranche stays under the limit. Watch for banks operating under the same licence, because the limit is per institution and two brands sharing one licence share one limit.
The downside is liquidity. Break a fixed term early and you usually forfeit interest, and moving money between banks adds transfer days. For cash you might deploy at short notice, that friction is a real cost.
Comparing the three parking options
| Feature | Money market ETF | Short govt bond ETF | Bank term deposit |
|---|---|---|---|
| Yield (approx, follows ECB) | Near €STR less ~0.1% TER | Slightly higher, varies with yields | Fixed for the term |
| Price stability | Very high | Good, small rate sensitivity | No price movement |
| Liquidity | Sell any market day | Sell any market day | Locked until maturity |
| Protection | Fund quality, no DGS | Fund quality, no DGS | DGS up to €100k per bank |
| Best for | Deploying from a broker soon | A slightly longer wait, higher yield | Fixed horizon, guarantee priority |
Where the account itself matters
If you plan to invest the lump through a broker anyway, park it there. Holding a money market ETF in the account while you decide means that on deployment day there is no bank transfer in the way; you sell the parking fund and buy your target ETFs in the same session. For a sum this size the broker’s custody model, costs and jurisdiction matter more than usual, so it is worth reading up on the best brokers for six-figure European portfolios first. And to sanity-check candidate parking funds side by side, our UCITS ETF comparison tool lets you line up TER, size and structure.
Then decide: lump sum or phase in
Parking buys you time to make the second decision well. The evidence broadly favours investing a lump sum immediately over drip-feeding it, because markets rise more often than they fall. But averages are cold comfort if you invest €150,000 on a Friday and the market drops 10% the next month; the regret can push you into selling at the worst moment. Phasing the money in over three to six months trades a little expected return for a lot of behavioural insurance, and for many people that is a fair deal.
If your sum is genuinely large and you are weighing whether to go it alone at all, I worked through that exact fork in a piece on handling half a million euro yourself versus a wealth manager. The parking vehicle should match your plan: a money market ETF for a lump-sum move or a fast phase-in; a short bond ETF or laddered deposits if you will feed it in slowly over many months.
What I would do with €100,000+
If the money were mine and I intended to invest it within a few months, I would open the brokerage account I planned to invest through, move the cash in, and hold it in a euro money market ETF. Simple, liquid, and one internal trade away from deployment. If I knew I would phase in over half a year and wanted the guarantee, I would split the cash across two banks under the €100,000 limit each, using short fixed terms that mature roughly when I plan to buy. What I would not do is leave six figures earning nothing, or park it in anything that can fall while I decide. Preserve first, deploy on a plan second.
Frequently asked questions
Q: Is a money market ETF safe for parking €100,000?
A: For a short holding period it is a sensible, low-risk choice, because the fund holds very short-dated, high-quality instruments whose price barely moves. Be clear that it is a fund, not a bank deposit, so it is not covered by the €100,000 deposit-guarantee scheme. Its safety comes from the quality and short maturity of its holdings, which is high but not a government guarantee.
Q: How is my money protected above €100,000 in a bank?
A: The EU deposit-guarantee scheme covers eligible deposits up to €100,000 per person, per bank. Amounts above that at a single institution are not guaranteed, so for larger sums you spread the money across separate licensed banks to keep each tranche under the limit. Check that two brands do not share one banking licence, or they share a single limit.
Q: Should I invest the lump sum all at once or spread it out?
A: On average, investing immediately beats drip-feeding because markets tend to rise over time. Phasing in over three to six months gives up a little expected return in exchange for reducing the risk of a bad-timing regret that makes you sell. Choose based on your temperament and the size of the sum relative to your net worth.
Q: Can I lose money in a short-term bond ETF while parking?
A: Yes, a little. Short government bond ETFs carry some interest-rate sensitivity, so if yields rise the price can dip a percent or two, and you could sell at a small loss if forced. The shortest-maturity funds and money market ETFs minimise this, which is why I prefer them for cash I might deploy at short notice.
Q: Where should I actually hold the parked cash if I plan to invest it?
A: If you will invest through a broker, park the money in that same brokerage account in a money market ETF. On deployment day you sell the parking fund and buy your target ETFs in one session, with no bank transfer in the way. This removes both delay and the temptation to leave cash idle.
Q: Is parking cash the same as building an emergency fund?
A: No. An emergency fund is permanent, always-liquid money for genuine emergencies, whereas parked cash is a temporary holding for a specific sum you intend to invest soon. They can use similar vehicles, but the emergency fund stays put while parked cash is meant to move into your portfolio on a plan.
