Bloomberg Terminal Is Ugly and Clunky—Everyone Still Uses It

Opening

Hello, subscriber. This is Oz’s Knowledge Talking. A tweet on X (formerly Twitter) recently sent a shock through the trading floors. The poster was none other than Mohammad Bagher Ghalibaf, Speaker of Iran’s parliament. The tweet itself was a short, mocking comparison of the oil market to the bond market — but the real story was in the last line.

“EUCRBRDT Index GP ”

At first glance it reads like an indecipherable code, but it’s actually a Bloomberg Terminal command. The implication was that a senior official from a sanctioned country was casually operating inside the very heart of Western financial infrastructure. The existing suspicion that Iran was quietly raking in huge sums from oil trading suddenly felt a lot closer to confirmed.

But I want to look at this from a different angle. Just what is the Bloomberg Terminal, that one line of command could set off this much noise? Why was Iran’s parliament speaker using it in the first place? And why, 44 years on, can the financial industry still not let go of this “clunky, expensive” machine?

Today, let’s follow these questions.

🛢️ What That One Line Actually Means

Let’s break the command down piece by piece.

EUCRBRDT is the ticker¹ for the Bloomberg European Dated Brent Forties Oseberg Ekofisk (BFOE) Crude Oil Spot Price. The name is a mouthful, but in plain terms, it’s the spot² price index for North Sea Brent crude³. It’s registered as an official time series on the European Central Bank (ECB)‘s data portal — a core benchmark of the global oil market.

Index marks this ticker as, well, an index rather than a stock or a bond — a market qualifier⁴. On a Bloomberg keyboard, this is exactly what the yellow keys (GOVT, CORP, EQUITY, INDEX, and so on) are for.

GP stands for Graph Price — the command to pull up a price chart for that ticker.

And the final is the Bloomberg keyboard’s famous green GO key — the “execute” button that plays the role of an Enter key. Interestingly, that shade of green is borrowed from the “GO” square on a Monopoly board, in the hope that every time a user hits the key, they collect some winnings.

Put together, the line reads:

“Pull up the spot price chart for Brent crude.”

Here’s the problem: this isn’t a command just anyone can casually try. The Bloomberg Terminal is a closed system that costs upward of $30,000 a year to access. And the fact that a senior Iranian official — sanctioned by the U.S. Treasury’s Office of Foreign Assets Control (OFAC)⁵ — appeared to be fluent enough in this command syntax to slip it into a tweet reads, all too neatly, as circumstantial evidence of sanctions evasion or oil-trading activity.

Of course, other explanations remain on the table — a staffer tweeting on his behalf, someone on his team drafting it, and so on. But the suspicion itself has already outgrown the realm of mere suspicion.

And this is where the real story begins. What exactly is this Bloomberg Terminal, with its cryptic command language?
