Chances for the 33-year bull run in the bond market to fall flat in 2016 increased when the Fed enacted a rate hike in December 2015 after almost a decade. But in reality, bonds kept bouncing throughout the first quarter on a low-yield environment in most developed markets across the world.

Thanks to China-led global market worries and the 12-year plunge in oil prices, the global market went berserk to start this year. All these buried risk-on sentiments and boosted relatively safer fixed-income securities in the quarter, pulling bond yields down.

In fact, the impact of the global financial market turmoil was so deep-rooted that the Fed halved its number of rate hike estimates for 2016 from four to two in its March meeting. Also, Fed chair Yellen reaffirmed a ‘cautious' stance on future policy tightening.

Needless to say, the very move dragged down the U.S. benchmark bond yields and pushed up its prices. Notably, yields on 10-year Treasury notes dropped 41 bps to 1.83% (as of March 30, 2016) in the quarter, leading U.S. Treasury valuation to soar.

Meanwhile, deflationary threats led the central banks of Japan and Euro zone to widen their already ultra-easy monetary policies. At its January-end meeting, BoJ set its key interest rate at negative 0.1%. BoJ then hinted at further cuts in interest rates if the economy fails to improve desirably. 
                         
In Europe, the ECB president Mario Draghi turned super dovish in March by raising the monthly bond purchase size to EUR 80 billion from 60 billion previously.
 
Also, ECB lowered the deposit facility rate to negative 0.4%, down from the previous rate of negative 0.3%. It also cut its main refinancing rate and marginal lending rates by 0.5% each to zero percent and 0.25%, respectively (read: Surprise ETF Winners & Losers Post ECB Easing).
 
Quite expectedly, the twin boosters of easy money policy globally and a delayed rate hike in the U.S. made fixed-income securities a winner in the first quarter. It would thus be interesting to note the ETFs that were the leaders in the bond space during the quarter. Returns are as per xtf.com.
