Forexpros - Last week saw the Swiss franc fall to a six-day low against the U.S. dollar on Friday, extending sharp losses from the previous session amid speculation the Swiss National Bank will take further action to weaken the currency.
USD/CHF hit 0.7785 on Friday, the highest since August 4; the pair subsequently consolidated at 0.7775 by close of trade on Friday, climbing 2.37% over the week.
The pair is likely to find support at 0.7236, Thursday's low and short-term resistance at 0.7855, the high of August 2.
The Swiss franc plunged nearly 4.6% against the greenback on Thursday, the biggest one-day drop since 1990, while the euro jumped by almost 5%, the most since its inception in 1999.
The Swissie weakened after SNB Vice President Thomas Jordan said Thursday that the central bank could further ease monetary policy without having to intervene in the currency market to curb the franc's recent gains.
Jordan added that a temporary tie between the Swiss franc and the euro would be legal under the SNB's mandate, as long as such a peg contributed to price stability.
Meanwhile, SNB officials declined to comment on speculation that Swiss lenders might start charging 1% on franc deposits from as early as next week.
On Wednesday, the SNB announced that it would take additional measures, including increasing liquidity to the money market and conducting foreign exchange swap transactions to curb recent gains in the currency.
The actions come after the SNB narrowed its three-month Libor rate to 0.25% from 0.75% on August 3, saying the currency was "massively overvalued".
The franc climbed to a record high of 0.7066 against the greenback on Tuesday, after the Federal Reserve pledged to keep its benchmark interest rate at an all-time low until "at least through mid-2013."
In a statement, the Fed said growth was much slower than expected and the labor market had deteriorated, underlining concerns over the U.S. economic outlook.
On Monday, market sentiment was rattled after ratings agency Standard and Poor's downgraded the U.S. sovereign debt rating by one notch to AA+ from AAA after markets closed last Friday.
The ratings agency kept the rating outlook at negative, suggesting a further downgrade could be possible within the next 12 to 18 months.
The downgrade prompted investors to shun riskier assets, such as stocks and higher yielding currencies, and flock to traditional safe haven assets like the yen, Swiss franc and gold.
