The loonie was well off early lows and closed up 0.01 of a cent at 98.15 cents US.
Concerns include the failure of Japan's central bank to unveil more measures to boost that country's economy and whether the U.S. Federal Reserve will start to taper off some of its bond purchases. There was also concern over a court challenge to the legality of the European Central Bank's approach to the euro crisis.
The Bank of Japan started a big monetary stimulus earlier this year in an attempt to get the economy out of a two-decade stagnation. And there had been expectations it would announce new measures Tuesday to temper the rise in government bond yields by extending the duration on its ultra-low-interest rates to banks.
Instead, the bank’s policy board merely upgraded its economic assessment and the Japanese yen strengthened at least one per cent against all its 16 major peers.
Meanwhile, investors have been closely monitoring developments in the U.S. and whether the economic picture has improved enough for the Federal Reserve to reduce the amount of financial assets it buys in the markets — so-called tapering. Speculation that it will has eased somewhat after last week’s slightly better-than-expected U.S. jobs report for May.
The quantitative easing program, involving the purchase of US$85 billion of bonds each month, has kept interest rates low and also helped fuel a strong rally on U.S. stock markets.
Traders also looked to the start of a two-day hearing by Germany’s constitutional court on the legality of a key European Central Bank program that has been credited with calming the 3 1/2 year-old euro debt crisis. The Federal Constitutional Court is considering arguments against the ECB’s offer to buy government bonds and lower borrowing costs for indebted countries.
Opponents of the bond-buying program say the program oversteps the ECB’s mandate, which forbids it from financing governments.
