Counterparty risk in arbitrage: how to spread money between exchanges

Counterparty risk in arbitrage: how to spread money between exchanges

An arbitrageur is used to counting risk in percentages and slippage. There is a risk that does not get counted that way and is still capable of wiping out a year's result in a single evening.

It is the risk of the venue itself. A hack, a withdrawal freeze, a closure, an account block, the events differ while the outcome for you is identical: the money exists and you have no access to it. We reckon this risk is underestimated more than any other, simply because it is not visible in the order book.

Why arbitrage has a special relationship with it

An ordinary trader holds a position in one place and risks one venue. An arbitrageur, by the very design of the work, holds money on at least two and usually on five to eight.

Hence the paradox. By spreading capital you reduce the share you lose from a single event, and at the same time you increase the number of venues, each of which can let you down.

The second nuance is subtler. A pair has two legs, and one venue dropping out breaks not half the position but the whole construction: the remaining leg turns from neutral into a directional bet.

The working balance rule

A simple formula that saves your nerves. On each exchange hold as much as genuinely circulates through your pairs in a week, and not a cent more.

Everything above that sum goes to your own wallet. Yes, there it does not work and brings no income, but it stays yours on any day of the week regardless of the news. The trade off is honest.

Checking yourself is easy. Ask yourself the question: if this venue stops withdrawals for a month tomorrow, what exactly changes in my life and my work? A frightening answer means one thing. The sum is too large.

How to judge the venue itself

Look at four things, and not one of them is about fees. Jurisdiction and regulatory status. The composition of the reserve fund. Whether the exchange publishes wallet addresses so anyone who wants to can check the balances themselves without relying on its own reports. And how the venue behaved in past crises.

The last point is more informative than the rest. A venue that once dealt with an incident honestly and returned the money behaves predictably the next time too.

Pay separate attention to the ratio of hot to cold storage. Where almost everything sits online for the sake of withdrawal speed, any backend breach hits the clients directly.

What to do today

Open the list of your venues and write out the sums. Not percentages but money: exactly how much sits on each.

From what we observe, the interesting part starts next: compare those figures with the weekly turnover of your pairs on the same exchange. Almost certainly on one or two venues you are holding several times more than you need, simply because that is how it worked out over time.

And set up spare accounts. In our view an opened and verified second tier exchange with nothing on it right now costs less than any insurance and saves you at exactly the moment the main venue stops.

Our tools

Spreading pairs across venues is easier when you see all the routes at once. Our arbitrage screener keeps dozens of venues in one window, refreshes quotes every second and shows each gap together with the volume actually behind it. The spread calculator helps you check what survives fees, network costs and slippage at your size. The bot is fully manual. It never connects to your exchange API keys.

To test the tools on a live market, ArbitrageScanner offers one day of free access to the whole ecosystem.

FAQ (Frequently Asked Questions)

1. What is counterparty risk in plain words?

The probability that a venue stops giving your money back. The cause can be anything: a hack, a withdrawal freeze, a closure or an account block, and the result for you is one and the same.

2. How much should you hold on one exchange?

As much as genuinely circulates through your pairs in a week. The rest goes to your own wallet: it brings no income but stays yours under any scenario.

3. Why is this risk higher for arbitrage?

Because the money sits on several venues at once, and one dropping out breaks the pair entirely. The remaining leg turns from neutral into a directional bet.

4. What do you look at when choosing a venue?

Jurisdiction, the reserve fund and its composition, the publication of wallet addresses and the exchange's behaviour in past crises. Fees are not the point here at all.

5. Why do you need empty spare accounts?

So you are not starting registration and verification at the moment the main venue stops. An opened account costs nothing and saves a great deal of time.

Conclusion

Venue risk is visible neither in the order book nor in a return calculation, which is why people remember it only after the news. Meanwhile it is exactly what can wipe out months of work in a single evening.

The protection from it is boring and works every time. Hold on an exchange precisely as much as circulates through your pairs in a week, spread the legs between venues and set up spare accounts in advance. Keep your main capital where it belongs to you.
