The dollar rose as high as 118.66 yen on December 15, its highest since February. The Conference Board said its US Consumer Confidence Index rose to 113.7, the highest since August 2001, as expectations for strength in job growth, business conditions and the stock market continued to build following Donald Trump's election to president. US house prices also continued their steady recovery in October, although a spike in borrowing costs could present a headwind to sustained home value gains, as rates rose after the election.
The upbeat data helped underscore expectations that the US central bank would raise interest rates more frequently next year, a view that gained traction after the Fed on December 14 projected three rate hikes next year compared with the two it predicted in September. "The next data to watch is US payrolls due on January 6," said Ayako Sera, market strategist at Sumitomo Mitsui Trust Bank in Tokyo. "Markets are prepared for data showing strong US economy but not for the opposite."
Sera added that volatility could be high for the yen as Tokyo trading thins ahead of the Japanese New Year holiday, which lasts from December 31 to January 3. The dollar index, which measures the greenback against a basket of six major peers, last stood at 102.97, down 0.1 percent and below its 14-year peak of 103.650 touched on December 20. The greenback was supported as US Treasury yields rose on Tuesday to one-week highs in response to the strong domestic data.
The dollar index has risen 5.3 percent since the US election, propelled by expectations that Trump would drive deregulation and fiscal stimulus. "Markets (will now) wait and see how the Trump administration will deliver its fiscal expansion, monetary easing and protectionist policy," said Minori Uchida, chief FX analyst at Bank of Tokyo Mitsubishi UFJ.
"Deregulation to compensate for smaller fiscal stimulus would not be favoured by the general public, but it will be later in the year should disappointment creep in," he added. The euro was last up 0.1 percent against the greenback at $1.0470. The common currency marked a 14-year low of $1.0352 on December 20, and concerns about Italian banks and upcoming elections in France and Germany look set to keep investors on edge into the start of 2017.
The Italian government is likely to pump around 6.5 billion euros ($6.8 billion) to rescue the country's third biggest lender Monte dei Paschi. The troubled Italian bank requested government support last week after it failed to raise 5 billion euros from private investors.
The Australian and New Zealand dollars were near multi-month lows on expectations of more tightening by the Fed following the strong US economic data. The Australian dollar edged up 0.2 percent to $0.7201, just above a seven-month trough of $0.7160 touched last week. The New Zealand kiwi inched up 0.3 percent to $0.6912, having plumbed $0.6863 on December 23, its lowest since June.
