If ever there was an example of an “overnight repo Black Swan” event, MF Global’s “repo-to-maturity” laddered trades seem to be it. Though, in this case, they’re probably better described as the realisation of the “short-term repo Black Swan”.
A.k.a institutions’ growing tendency to risk it in the short-term repo universe, to beat the crappy returns being offered in the “risk-free” market.
So, while most of the media has been commonly referring to MF’s sovereign bond positions as proprietary bets gone wrong, there’s more to it than just that.
If anything this was a financing position (or liquidity trade) — not a bet on the future direction of the bonds themselves.
What’s more, if executed properly the trade should — at least on paper – have posed little or no risk.
