The Dollar has fallen drastically in the last week to a new low of 3.94. This is a 7% fall from the high we saw at the end of April of 4.256. So why the drastic fall?
There are two things to consider here, firstly what has been happening in the US and secondly what has been happening in Israel.
1) The US Dollar. This has fallen against most of the major currencies over the last week, most notably against Sterling (GBP/USD has gone from 1.5 to 1.59 in the last week). The dollar has weakened for a variety of reasons, most notably investors appetite for risk has increased.
Normally during any financial turmoil investors put their money in to Dollars as it is considered the safe thing to do. However, now that investors seem to be willing to take some more risks that could give them more rewards they are selling their Dollars (only paying 0.25% interest) and putting them into currencies that may give them more.
2) The Bank of Israel. They have over the last 10 months bought billions of Dollars. They currently purchase on average $100 million a day. This policy has helped strengthen the dollar (or weaken the shekel!) from the lows we saw early 2009 of 3.3 to the highs we saw late April. However, there is a limit to how many dollars they can purchase.
The Bank of Israel wants a weaker shekel and a stronger dollar to help israeli exports.
Last weak there were rumours that the Bank of Israel is looking for ways of selling their dollars. This has caused the markets to fall. Obviously the Bank of Israel denid this and have stated that they will continue to buy dollars.
So a combination of the two above has caused the shekel rate to plummet over the last week. It is my opinion that the Bank of Israel will do everything in its power to keep exchange rates above 4 and hopefully let them settle above 4.2.
