Key Quotes:

“Gazprom announced yesterday the flow through Nord Stream 1 will be cut to 20% of capacity in the next day or two, for an indeterminate time. Prices at the Netherland virtual trading point have risen to EUR 182/MWh, close to post-March highs. The euro hasn't over-reacted to this news, however.

Maybe also, euro shorts are finally big enough, after another increase last week, to cushion the currency.”
