Jaeggi, who won the Godzilla billing for his aggression, is reportedly a keen equestrian. This gives him a common interest with Masters, who is an experienced horse rider. Masters also shares Jaeggis reputation for being extremely assertive, which has given her a high profile that has been a double-edged sword, both for her own progress and in terms of her value to her long-time employer, JPMorgan.
She first became widely known as head of marketing for credit derivatives when JPMorgan bankers were at the forefront of development of a market for synthetic trading of credit. A product that started as a way to offload bank exposure and improve liquidity soon metastasized into a Frankensteins monster that was widely blamed for exacerbating the credit crisis of 2008. That turned Masters reputation as a credit derivatives evangelist into a liability, even though JPMorgan itself was able to avoid losses on the scale of firms such as AIG, Merrill Lynch, Morgan Stanley and UBS.
Masters had already moved on, after a stint as CFO of JPMorgans investment bank, to a role as global head of commodities with a mandate to match or exceed the earnings generated by Goldman Sachs and Morgan Stanley, the two traditional bank leaders in commodity trading.
Once again she proved to be a magnet for attention and controversy. JPMorgans drive into commodities featured some quick early wins after Masters took the reins in 2007. The bank was already established as a commodity derivatives dealer and had deployed its trademark combination of financing firepower and an ability to value multiple positions to take over the books of failed energy hedge fund Amaranth for a substantial trading profit in 2006.
Masters led a drive to build scale in all large existing commodities markets such as oil and gas and to supercharge the development of new areas such as coal trading. Trading books and staff were inherited from Bear Stearns and acquired from RBS Sempra as part of this expansionary push, and dealing lines were increased for many businesses.
This led to a sharp increase in commodity-trading volumes and revenues at JPMorgan, although also to some trading hiccups. These included a loss of around $130 million on coal that attracted attention not because it had much of an impact on JPMorgans bottom line, but because it became obvious that the bank was running big directional positions in a market that was in its infancy.
This approach to rapid growth might seem to tailor Masters perfectly for a senior role at Mercuria. The Geneva-based firm has joined in the explosion in scale of independent commodity traders over the past decade, but it is still smaller than rivals such as Glencore, which has trading revenues roughly twice those of Mercuria, and Vitol, which is around three times as large. And independent commodity trading firms have historically shown few signs of squeamishness about the reputational issues that have become a growing concern for JPMorgans top management.
Glencore was founded by Marc Rich, a US tax exile who based the firm in Switzerland in part because he was accused of breaching oil sanctions on Iran; other commodity traders have seemed equally unconcerned about the James Bond villain image that they sometimes project.
But JPMorgan did not decide to scale back in commodities purely because of the increase in reputational issues affecting the bank while the Masters plan was being implemented, or because of the rise in capital costs for trading positions under new regulation.
There were also questions over whether or not the bank could make a sustainable profit from a big commodities trading operation, even before regulatory costs increased.
Masters certainly delivered revenue, although JPMorgan, like most banks, does not disclose how much commodities contribute to its overall fixed-income franchise. It is not clear how much this outpaced a substantial cost base, however. Commodities heads at rival banks have done back-of-the-envelope estimates of the costs associated with JPMorgans franchise, based on their knowledge of the terms offered to some staff hired under Masters, the number of front-office employees and the revenues in different sectors in recent years. They have come to the conclusion that it is unlikely that the bank made much profit, unless it was via undisclosed directional bets of the type that bankers including Masters now disavow.
And the revenue side of the equation has been under pressure recently. Coalition, a consultancy firm, estimates that the top-10 investment banks generated just $4.5 billion in commodity revenue last year. That might be a slight undercount, depending on how related banking revenue is measured, but it is still a far cry from a few years ago, when leading firms such as Goldman, Morgan Stanley, Barclays and latterly JPMorgan each comfortably generated in excess of $1 billion a year from commodities.
The newly dominant breed of independent commodity trading firms now put the banks in the shade with revenues from their relatively unconstrained dealing: Mercuria had $98 billion of revenue in 2012, for example.
The firm will have to decide how best to deploy Masters if she does come on board soon after the signing of the deal to take on JPMorgans physical commodity business for $3.5 billion, which includes the value of the assets.
Mercuria already has one former bank commodities supremo on its staff in the form of Roger Jones, ex-head of commodities at Barclays, who was hired in late 2012 to run non-oil trading. Two veteran bank heads might start to feel like a crowd, especially as Mercurias CEO Dunand and his partner Jaeggi might well think that they have the core business of oil trading covered, given their own backgrounds.
But there is no denying that Masters is an energetic manager with a flair for promoting the future prospects of developing financial markets, which might prove to be a boon for Mercuria as it seeks to expand its presence in new commodity sectors.
And a move by Masters to Mercuria would give hope to some of the beleaguered commodity executives left on Wall Street and in the City of London who recently learned the details of the diminished and partly deferred bonuses they earned after a poor 2013 for the sector.
If she does join Mercuria, it might be a signal that physical commodities staff from JPMorgan will be retained by the trading firm and other employees hired.
Commodity trading has enjoyed a minor revival so far this year, with the benchmark DJ-UBS index up almost 9% by late March, and a combination of weather and geopolitical uncertainty contributing to increased volatility in key markets.
News that Blythe Masters is hiring again might really put a spring in the step of commodity staff.
