Who benefits from the rise in the value of the Dollar? (Or rather, the fall in the value of the NIS?)
Exporters, landlords, people with foreign currency deposits - everyone and anyone who has foreign-currency-based income.
Who suffers?
Importers, and anyone who would want to buy anything imported, and gets NIS-based income.

Now, I'll let you think which group is more closely related to Herr Klein et al.

Now, for Klil's Conspiracy Theory of the Week (tm): Due to the political and economical situation in Israel, doom is approaching at a steady gait. Therefore, the elite have decided to strongarm the Bank of Israel into lowering the interest rate, thus allowing them to use their foreign-currency-based power in a limited interval of time, before the whole economy plunges into utter chaos.

Then there's the idea, that perhaps the Government is trying to make the immigrants from Argentina feel more at home.

You're leaving out the most essential part: how much more? How many more jobs? Will there be more job openings at the exporters` than there are layoffs at the importers`?

Why is a big increase in the local value of the dollar good now, when it was bad in the early 1980's?
