Nikkei 225

With the US closed for Memorial Day and UK markets offline due to a bank holiday, overnight volumes have been weaker than normal on little newsflow. The main story remains the stronger USD following Yellen's hawkish Friday speech, which not only led to the lowest Yuan fixing since February 2011...

... but pushed the USDJPY almost as high as 111.50 overnight before paring gains, however it was enough to send the Nikkei 1.4% higher.

In a world where fundamentals don't matter, everyone's attention will be on Janet Yellen who speaks at 1:15pm today in Harvard, hoping to glean some more hints about the Fed's intentionas and next steps, including a possible rate hike in June or July. And with a long holiday in both the US and UK (US bond market closes at 2pm today), it is no surprise overnight trading volumes have been dreadful, helping keep global equities poised for the highest close in three weeks; this won't change unless Yellen says something that would disrupt the calm that’s settled over financial markets.

In what has been another quiet overnight session, which unlike the past two days has not seen steep, illiquid gaps higher in US equity futures (the E-mini was up 3 points and accelerating to the upside as of this writing so there is still ample time for the momentum algos to go berserk), the main event was the price of Brent rising above $50 for the first time since November with WTI rising as high as $49.97.

As shown in the chart below, Brent crude surpassed $50 a barrel for the first time since November, lifting commodity companies and buoying currencies where oil is produced.

The single biggest event overnight was the PBOC's devaluation of the Yuan to the lowest since March 2011, setting the fixing at 6.5693, the highest in over 5 years and in direct response to a stronger dollar, which however if one looks at the DXY remains well below the recent highs in the 100 range, suggesting for China this is only just beginning.

Yesterday's weak dollar headfake has ended and overnight the USD rallied, while Asian stocks dropped to the lowest level in 7 weeks and crude oil fell as speculation returned that the Federal Reserve will raise interest rates as early as next month. The pound jumped and European stocks gained thanks to a weaker EUR.
