Eoin Treacy's view Today's interesting charts - Here are some charts I believe will be useful in monitoring the development of this crisis.

Eurobunds - surged again today in strong commonality with other sovereign bonds. A sustained move below 130 would now be required to confirm a return to medium-term supply dominance.

Brent Crude - gave up most of Friday's bounce but needs to sustain a move below $100 to confirm medium-term top formation completion.

DJ EuroStoxx Banks Index - failed to sustain the early rally and closed on the low of the day. An upward dynamic held for more than a day or two is required to confirm more than temporary support in this area.

Asia Dollar Index - continues to revert towards the mean but a sustained move below 117 would be required to question the consistency of the medium-term uptrend.

EUR Libor 3-month - EUR Generic 3-month spread - continues to extend the breakout from the 2-year base, emphasising the continued sense of heightened risk in the financial sector.

Indonesia - found at least short-term support in the region of the 200-day MA today but will need to hold above or in the region of 3700 for the medium-term uptrend to remain relatively consistency.

FTSE Xinhua A600 Banks - broke downwards from the more than yearlong range two weeks ago and continues to extend the decline. A sustained move back above 8700 would now be required to confirm a return to demand dominance.

FTSE-100 - approaching last year's lows but a clear upward dynamic held for more than a day or two would be required to confirm anything other than temporary support in the 5000.
