The Grand Exchange is going beyond max cash — here's how the 2.147b wall finally falls

The short version: For over a decade the Grand Exchange has capped a single trade at 2,147,483,647 coins — max cash. On June 15, Jagex laid out a rework that lets GE offers settle above that wall by pairing coins with platinum tokens, so a handful of ultra-rare items can be traded safely in the GE again. Here's how it works, what else is changing, and the account move landing later this year.

01The 2.147-billion wall, and why it matters

The Grand Exchange has been the backbone of Old School's economy for well over a decade — supplies before a boss trip, loot after it, and flips in between all run through it. But one limit has quietly aged badly: the most coins a single offer can trade is still 2,147,483,647.

For almost every item that's fine. For a tiny handful of extreme rares — the elusive 3rd Age Pickaxe is Jagex's own example — prices sit above max cash, so those trades can't happen through the GE at all. Players fall back on manual in-person trades with Platinum tokens, or coordinate through third-party sites and Discords. Jagex is blunt about the downside: it strips away the protection the GE gives you, raises the risk of scams, and muddies price discovery for everyone else. And because new high-end content tends to launch well above max cash before supply settles, the problem keeps recurring.

02How the fix actually works

The obvious question — "wasn't 2.147 billion the biggest number Old School could handle?" — has a real answer. That limit comes from a lot of older systems using 32-bit integers, where 2,147,483,647 is the maximum value. Jagex hasn't changed that for item stacks: you still can't carry more than 2.147b of either currency in a single stack.

Instead, Jagex added 64-bit number support to the engine, RuneScript and supporting services, and taught the GE to treat Platinum tokens as a proper currency within it. Any value above the old 2.147b limit is handled automatically across the two currencies — so a very large trade is represented as a combination of coins and platinum, without touching stack sizes. In theory the underlying tech could reach into the quintillions; in practice, with only coins and platinum to hold value, the effective ceiling lands around 2.149 trillion GP. Jagex notes it borrowed heavily from how modern RuneScape enabled higher-value exchanges, but kept it grounded in the coins-and-platinum players already know rather than adding a currency pouch.

The guardrails stay in place. Existing buy limits are unchanged. GE tax still applies to these trades — keeping the gold sink working — and it remains capped at 5 million coins per item. Jagex is candid that some players will still trade the very biggest items outside the GE to dodge tax, but reckons plenty will value having the safe, convenient option back.

03The other GE improvements on the table

Alongside the max-cash change, Jagex flagged a set of broader GE ideas it's exploring. These are earlier and less locked-down, but the list is worth knowing:

• ExploringMore responsive guide prices, so they track current market conditions day-to-day rather than lagging.
• ExploringImproved item search — better name matching and category filters.
• ExploringClearer buy-limit indicators, showing when an offer has hit its limit and when it resets.
• ExploringBetter price-discovery tools to help you gauge what it actually takes to buy or sell an item.

The beyond-max-cash change is targeted for late Summer to Autumn 2026, with the wider improvements following later. As ever, it's a proposal — Jagex asked for feedback before it ships.

04Also this week: the full move to Jagex Accounts

The GE wasn't the only structural news. On June 12, Jagex confirmed the full transition to Jagex Accounts is happening this year — no exact date yet, but the team is looking at around November or December 2026. Jagex Accounts launched back in 2023 on a modern codebase with stronger passwords, better 2FA and login/change notifications, and the share of active players using them is now over 85%.

Once the transition lands, a Jagex Account will be required to play RuneScape and Old School RuneScape — except for Steam, Apple, Google and Game Center logins, which are covered. If you already use a Jagex Account or one of those platform logins, you don't need to do anything; if you don't, Jagex recommends upgrading early to avoid a forced switch at an awkward moment. Launcher changes are coming so players on every supported OS keep access.

• PaymentsSeparately, Jagex is retiring Boku as a website payment method from 17 August 2026. Anyone using it can switch to card, PayPal or another supported method in account settings before then.

05The market corner: the items that live above the wall

We don't run a fabricated price table for a past week — the live Grand Exchange prices API only serves current values, and we won't invent June figures. But the economics behind this update are worth stating plainly, because they're the whole reason it exists.

A small set of items — Jagex singles out the 3rd Age Pickaxe — routinely trades above 2.147b, which is exactly why their owners currently have to leave the GE to buy or sell. New top-tier content tends to debut above max cash too, then drift down as supply catches up. If this change ships, those day-one trades come back inside the GE's protection — and every one of them keeps paying GE tax (capped at 5m per item), so the gold sink grows with them. That's the quiet economic point: it's as much about safety and tax as convenience.
