What is treasury trading and should your startup be doing it?

Somewhere in Europe right now, there are thousands of startups sitting on seven figures of cash in current accounts earning essentially nothing. They raised a round, put the proceeds in the bank, and have been spending it down ever since — leaving the unspent portion completely idle.

This is understandable. Running a startup means constant demands on your attention, and optimising your cash balance rarely makes it to the top of the list. But the opportunity cost is real. And in the current interest rate environment, it's larger than it used to be.

What treasury trading actually means

Treasury trading, in a business context, means deploying idle cash into short-term, liquid financial instruments to earn yield while keeping the money accessible when you need it. The most common instruments are money market funds and short-dated government securities.

Money market funds hold a portfolio of short-term debt — government bonds, treasury bills, commercial paper — and pass the yield through to investors. They're designed to maintain a stable net asset value and offer daily liquidity. Short-dated government bonds (T-bills and similar) are direct obligations of national governments, typically with maturities between one week and twelve months. Both are considered low-risk by most institutional standards.

The goal is not speculation. It's not generating outsized returns. It's avoiding the situation where capital sits completely idle when liquid instruments can earn a meaningful return with minimal additional risk.

How it works mechanically

The traditional version of corporate treasury management required a treasury team, bank relationship managers, and a fair amount of paperwork. The modern version is largely automated.

You set a minimum operating balance — the amount you want to keep immediately available in your current account for payroll, supplier payments, and operational needs. Anything above that threshold is automatically allocated to treasury instruments. When your balance drops below the threshold because you've made a large payment, funds sweep back automatically.

Same-day liquidity is what makes this viable for startups. Unlike a fixed-term deposit, you can unwind your position and access the full amount any business day, without penalty or notice periods. That matters when your cash needs can be hard to predict six months ahead.

When does it actually make sense?

The honest answer depends on your cash position and company stage.

If you're pre-revenue with €200K runway, the yield on your treasury balance doesn't justify the management overhead. Spend your attention elsewhere.

If you're post-Series A, holding €2M or more in runway, and that cash is sitting in a current account, the calculation is different. At 3% annualised yield — a reasonable benchmark for short-term instruments in the current environment — €2M generates €60,000 per year. At €5M, that's €150,000. That's real runway extension without any additional revenue. It's worth understanding.

The inflection point is somewhere around €500K–€1M in cash. Below that, the absolute yield is unlikely to justify any meaningful management overhead. Above it, the question shifts from whether to do it to how to set it up efficiently.

The risk picture — be honest about this

Treasury products are investments, not deposits. This is an important distinction that matters both practically and in how you communicate it to your board.

Bank deposits up to €100,000 are covered by the European Deposit Guarantee Scheme. Money market funds and government securities are not deposits — they're investment products, and their value can fluctuate. In practice, the short-term, high-quality instruments used for corporate treasury have an excellent track record of stability and liquidity. But the risk is not theoretical zero, and you should be transparent about this with your board.

For most post-Series A companies, the relevant risk question is not "could I lose money?" (theoretically yes, practically very unlikely with conservative instruments). It's "could I lose access to this money when I need it?" With well-chosen liquid instruments, the answer is no — but do your homework on the specific product.

Common mistakes

Locking up too much. The point of treasury management is yield on your excess cash, not yield on all your cash. Over-allocating and then needing to unwind positions quickly to cover payroll creates unnecessary friction. Set a conservative minimum operating balance and stick to it.

Chasing yield into riskier instruments. Money market funds and short-dated government bonds are the appropriate instruments for most startups. Longer-dated bonds, credit products, or anything with meaningful duration or credit risk is a different conversation — one that requires more specialised oversight than most startup finance teams have capacity for.

Not telling your investors. Some term sheets or investor agreements include restrictions on how you hold cash. Check yours before setting this up. Most don't restrict it, but it's worth being certain — and even if there's no restriction, informing your board in advance is better than explaining it after the fact.

The practical starting point

For Eduvo Scale subscribers, treasury is available directly from your dashboard. You set your minimum operating balance, Eduvo automatically allocates excess to low-risk instruments, and funds are available same-day when you need them. There's no separate account to open, no relationship manager to call, no additional paperwork beyond initial setup. The yield accrues and is visible in the same dashboard as your current accounts and cards.

"Idle cash isn't a neutral decision. Leaving €3M in a current account for 18 months is a choice — and it has a real cost."

For the companies where treasury trading makes sense, starting is simpler than most people expect. The complexity that once surrounded corporate treasury management has largely been automated. The main thing standing between most startups and meaningful yield on their cash is simply the decision to start.

The opportunity hiding in your current account

Most startups hold more cash than they realise sitting completely idle. Between funding rounds, ahead of tax bills, or simply as a prudent runway buffer, there is usually a meaningful balance that is not needed this week or this month. In a higher-rate environment, leaving that money earning nothing is a real, if invisible, cost. Treasury trading is simply the practice of putting that idle cash to work — earning a return on balances you are not currently using, while keeping the ability to access them when you need them.

Why startups historically ignored this

Treasury management used to be the preserve of large companies with dedicated finance teams, banking relationships, and the time to actively manage instruments. For a small startup, the effort and minimums made it impractical, so the default was to leave everything in a current account earning nothing. What has changed is that platforms now automate the whole process — assessing your balance, allocating excess above an operating threshold, earning a return, and returning funds when needed — without requiring a treasury desk. The capability has been democratised, and startups that take advantage of it capture a return that used to be available only to much larger organisations.

Liquidity is the whole game

For a startup, the cardinal rule of treasury is that liquidity comes first. The entire point of a runway buffer is that it is there when you need it, so any treasury approach that locks cash away for fixed periods is dangerous for an early-stage company. The right model keeps funds accessible — same-day liquidity rather than multi-month lock-ins — so that earning a return never compromises your ability to make payroll, seize an opportunity, or weather a surprise. Yield is the benefit; liquidity is the constraint that must never be violated.

Setting an operating threshold

The mechanism that makes this safe is the operating threshold: the minimum balance you always keep immediately available for day-to-day needs. Everything above that line is eligible to be put to work; everything below it stays untouched. Set the threshold thoughtfully — high enough to cover your real operating rhythm with comfortable margin, including upcoming large outflows like payroll, tax, or a planned hire — and the automation can confidently work the excess without ever putting the business at risk. As the company grows and its cash needs become more predictable, the threshold can be tuned.

Understanding the risk honestly

Treasury products are not the same as a deposit, and it is important to be clear-eyed about that. Returns are not guaranteed, values can fluctuate depending on the instruments involved, and treasury balances are generally not covered by deposit guarantee schemes in the way a bank deposit might be. This is not a reason to avoid treasury — it is a reason to understand what you are holding, keep your operating buffer genuinely safe and liquid, and treat the yield on excess cash as a sensible optimisation rather than a place to take risks you cannot afford. Independent advice is worth taking if you are unsure.

When it is worth doing

Treasury trading earns its place once a startup is consistently holding excess cash — typically after a funding round or once the business is generating surplus. Below a certain balance the returns are too small to matter and the focus should be entirely on growth. Above it, leaving six or seven figures idle is a quiet drag on the business that is trivial to fix. The judgement is simply whether the idle balance is large enough that a modest return on it is worth the small effort of switching the capability on — and for a well-funded startup, that threshold is crossed sooner than most founders expect.
