EghtesadOnline: Sterling slid to three-month lows in Asia on Monday with investors again spooked by concerns over Britain's exit from the European Union, while U.S. policy uncertainty lingered ahead of President-elect Donald Trump's inauguration.
Regional share markets were hesitant with MSCI's broadest index of Asia-Pacific shares outside Japan up just 0.09 percent. Japan's Nikkei eased 0.3 percent, while Australia added 0.5 percent.
All the early action was in currencies where the pound sank as low as $1.1983, depths not seen since the flash crash of October, having finished around $1.2175 in New York on Friday. It was last down 1.1 percent at $1.2044, Reuters reported.
Investors have been worried such a decisive break from the single market would hurt British exports and drive foreign investment out of the country.
"It is impossible to say by how much a hard Brexit could weaken GBP, but we do not believe that a further 5-10 percent depreciation should be regarded as an extreme scenario when set aside the UK's high dependence on foreign capital," wrote analysts at JPMorgan in a note.
The flight from sterling benefited the safe-haven Japanese yen, with the pound down 1.3 percent to 137.57 yen while the U.S. dollar dipped to 114.24.
Trading was erratic with currencies gyrating on very little volume. The dollar edged up 0.2 percent to 101.390 on a basket of currencies, while the euro pared initial losses to stand at $1.0632.
WAITING ON REFLATION
The dollar index put in its worst weekly performance in more than two months last week as investors reconsidered the whole "reflation" trade - that Trump's promises of debt-funded fiscal spending and lower taxes would stoke inflation and drive the Federal Reserve to raise interest rates faster.
Fed Chair Janet Yellen will have an opportunity to lay out her thinking with speeches on monetary policy on both Wednesday and Thursday this week.
All eyes will then be on Trump's inauguration on Friday for any clarity on his economic plans.
"The market is showing greater reluctance to push on with reflation-type trades without more details of proposed fiscal spending plans and the economic data to back it up," said analysts at ANZ in a research note.
"It looks as though more than just reasonable data will be needed to see yields and the dollar push higher again. Some decent positive surprises may be necessary for the market to gain conviction."
Asian markets are also waiting anxiously to see if Trump makes good on a campaign pledge to brand Beijing a currency manipulator on his first day in office, and starts to follow up on a threat to slap high tariffs on Chinese goods.
Analysts fret that the specter of deteriorating U.S.-China trade and political ties is likely to weigh on the confidence of exporters and investors worldwide.
Wall Street ended last week mixed, with the Dow off slightly but the Nasdaq at a record high.
Sentiment this week could be driven by results from the major banks with Morgan Stanley, Citibank and Bank of New York Mellon among those reporting.
In commodity markets, oil prices inched higher after shedding around 3 percent last week. Brent crude was up 9 cents at $55.54 a barrel, while U.S. crude rose 7 cents to $52.44.
Spot gold added 0.5 percent to $1,202.80 an ounce.
