* Upbeat US data somewhat counters dovish Fed
* Sterling firmer on more signs of UK economic strength
(Recasts, adds details)

LONDON, June 20 The dollar was under pressure on
Friday, heading for its biggest weekly loss in over two months
against a basket of currencies following the Federal Reserve's
surprisingly dovish policy outlook.
In contrast, the Bank of England's (BoE) hawkish bias was
driving the yield gap between two-year British gilts
and U.S. Treasuries higher, helping the pound trade
near 5-1/2 year highs against the dollar.
"Sterling is a favourite right now and the BoE seems to be
the only major central bank that is likely to deliver on higher
rates," said Niels Christensen, FX strategist at Nordea.
"The dollar hasn't had a great week after the Fed
disappointed some who had positioned for a slightly more hawkish
bias from (Fed chair) Janet Yellen."
The dollar index edged down to 80.289, not far from a
one-month trough of 80.147. It was down 0.3 percent on the week,
its biggest decline in two months.
Investors sold the dollar after the Fed on Wednesday sounded
comfortable about the outlook for inflation despite recent signs
of a pick-up in price pressure. That dashed some expectations
the U.S. central bank might have to start lifting interest rates
earlier than expected and initially pushed U.S. Treasury yields
But data on Thursday showed new claims for jobless benefits
fell last week and factory activity in the mid-Atlantic region
accelerated in June, prompting Treasury yields to reverse
higher. The dollar, though, was still lagging that pick-up in
yields, traders said.
IMPLIED VOLS CRUSHED
Implied volatilities, a gauge of how sharp currency swings
are likely to be, have fallen further after the Fed meeting.
The Fed and the Bank of Japan are still pumping billions
into the banking system and the European Central Bank will
launch new four-year loans in September. With the global
financial system awash with cash, volatility indices across
asset classes have fallen, supporting riskier assets like stocks
and higher-yielding currencies.
The one-month euro/dollar implied vol was at 4.50
percent, close to seven-year lows and mirroring similar moves in
stocks' indices like the ViX and VSToxx.
The euro was up slightly on the day at $1.3610, not
far from a two-week high of $1.3644 reached on Thursday in the
wake of the Fed's policy outlook.
"The euro looks well supported. The ECB may have eased but
that does not change the fact that the euro zone enjoys a
current and trade surplus. The rest depends on how economic data
and U.S. developments pan out," said Sho Aoyama, senior market
analyst at Mizuho Securities in Tokyo.
Sterling hovered within striking distance of a 5-1/2-year
high of $1.7064 hit on Thursday thanks in part to data
that showed UK factory orders grew at their fastest pace in six
months in June.
The robust report highlighted the probability that the BoE
could raise rates well before the Fed.
