The Rogue Traders

He knew every gap in their system. They knew every number he produced.

Paris, 2005. Marc Aurel spent five years in compliance learning exactly where the bank's surveillance cameras point — and where they don't. When he finally makes it to the trading floor, he uses that knowledge to build something the system was never designed to see. A €49 billion position. Disguised as routine arbitrage. Generating returns so extraordinary that no one asks the question that would end it.

By the time a compliance officer works late on a Friday evening in January 2008, it's already too late for a clean answer. The bank faces insolvency if it holds. It faces scandal if it discloses. It spends three days selling in secret, feeding a market collapse it refuses to explain — while it decides what story it needs to tell.

Marc is that story. Rogue employee. Exceptional deception. Acting alone.

But a board member sold €86 million in shares eleven days before anyone officially knew there was a problem. And a set of handwritten meeting notes — kept in a private file, never entered into the investigation record — describes a trading desk with returns that were "structurally inconsistent with its mandate." Six weeks before the sale.

The model said the hedge was clean. The basis said otherwise.

From a high-rise desk overlooking Manhattan, a risk officer watches a natural gas spread curve dislocate in real time. VaR is moving. Liquidity is thinning. The exposure report that looked routine at the open is now a stress scenario with a name on it.

Basis Risk is a compact Rogue Traders novella about model risk, hedge failure, and the moment a desk discovers that the protection built to save the position has become the trade that breaks it.

For readers who want the mechanics without the noise — and the specific terror of being right about the world and wrong about the hedge.

Novella length. Reads in one sitting.
