The pound was the top performer while the yen lagged as risk trades strengthened. Later, Kuroda and several second-tier releases highlight the calendar.

USD/CAD rose about 40 pips following the Bank of Canada decision.  The BOC maintained a slight dovish bias but there was nothing in the statement that screamed to buy the pair. If anything, across-the-board higher inflation forecasts due to rising energy prices and a softer loonie were a reason to sell USD/CAD.What stood out was the BOC emphasis that a pickup in exports and business investment is required to spur a sustainable recovery. The thing is, Poloz has been looking for that since he started at the bank and it hasn't come.

The BOC has expressed befuddlement and trend. All the elements are there, they say, but it's just not happening. Higher competition and offshoring help explain the export weakness but slow business investment is a problem in all developed countries.

Central banks have been wrong about investment for awhile and if it never truly materializes, all trades based on higher interest rates are at risk.

The Fed was also in the spotlight but Yellen revealed very little. The market was worried about hawkish commentary like we saw after the FOMC but there was nothing to hint a higher rates. She pointed to data and said downside risks to inflation are her chief concern.

The Beige Book noted a consumer spending pickup and that's a key factor for the near-term US outlook. Without spending (and business investment) sustainable new jobs will never materialize.

Up next, at 0000 GMT, BOJ leader Kuroda speaks and could offer some dovish hints. That's because the Japanese cabinet is rumored to be downgrading its economic assessment today for the first time since 2012. That's often seen as a precursor to central bank action.

At 0130 GMT, the quarterly business conditions index from the National Australian Bank is due. The prior reading was 8.

The trade has been to ignore Ukraine until the bullets started flying, well on Tuesday they began to fly and it caused a bout of risk aversion. The US dollar was the top performer while the yen lagged. Chinese GDP is a major risk in the hours ahead.

Tuesday was a busy day in markets. The initial focus was on US CPI (slightly high) and the Empire Fed (soft) but quickly shifted to Ukraine. On the weekend, pro-Russia separatists captured about a dozen government buildings in Eastern Ukraine. The government pledged a military response and delivered it by retaking an airfield.

Reports suggested 11 men were killed in the operation and a Ukrainian general said it was only the first step. Putin responded that the crisis had been “sharply escalated” and said the actions were unconstitutional.

The yen rallied as the headlines tricked out, sending USD/JPY down to 101.50 and EUR/JPY to a one-week low.

A turnaround began when Nikkei reported that Japan's government will downgrade its economic assessment on Thursday for the first time since 2012. The move could be the first step towards further easing.

USD/JPY rebounded back to 101.90 and it was assisted by a turnaround in US stocks. The Nasdaq touched the lowest since November but reversed to close slightly higher.

The Australian dollar was soft as commodities slumped. The World Gold Council reported on gold stockpiling for the shadow banking system in China and that sparked a quick $40 drop in gold. The government cracked down on similar stockpiling in copper last year, leading to a persistent selloff.

The focus will remain on AUD in the hours ahead with China set to report on industrial production, retail sales and Q1 GDP – all at 0200 GMT. The consensus is for 1.5% q/q growth, which is a modest 6% annualized pace. The collapse in trade numbers at the start of the month could be a negative but the trade balance was strong and that may add an upward bias. Any miss will immediately hit the Australian dollar and it could prove to be a lasting move. 

The limp US dollar reaction to the upbeat retail sales report highlights the divergence between market and economist expectations. On Monday, the Australian dollar was the top performer while the euro lagged. The RBA minutes are the highlight in Asia-Pacific trading.

Headline retail sales rose 1.1% in March, the best month since Sept 2012 and beating the 0.9% consensus. The previous month was also revised to +0.7% compared to +0.3% originally reported. The market more closely watches the control group and it painted a similar picture up 0.8% compared to 0.5% expected. There weren't any caveats in the report but the dollar couldn't take advantage, rising 15-20 pips and then fading. USD/JPY rose above 102.00 then slipped back to 101.70. EUR/USD and cable fell to session lows but wouldn't go any further.

If the dollar can't rally on good news, especially as it comes off a rough week, it's tough to envision a push higher. A key spot to watch is bonds. The 10-year Treasury chart is similar to USD/JPY and a break below 2.57% from the current 2.63% is an inflection point to watch.

The largest move on the day was in the euro but it was largely on the open. The catalyst was jawboning from Draghi but strong words are no replacement for action and the market doubts his sincerity, at least in the near term.

The focus switches to the Australian dollar lately with the minutes of the April RBA meeting due at 0130 GMT. The minutes could highlight the more-optimistic shift from Stevens & Co. Comments about investment and housing inflation could grab headlines and fuel AUD gains.
