BlackRock, Bloomberg, State Street Global Advisors, Tradeweb and Leading Broker Dealers Announce Market Standard Methodology for Fixed Income ETFs

Jul 27, 2015

Standard approach agreed for the consistent calculation of yields, spreads and durations for fixed income ETFs

July 27, 2015, New York / London – Global leaders in the fixed income ETF market have announced a market standard methodology to enable bond buyers to calculate key metrics for fixed income ETFs. This approach will enhance the ability of investors to conduct intra-day analysis of different ETFs and between ETFs and other fixed income instruments across multiple trading platforms. BlackRock, Bloomberg, State Street Global Advisors (SSGA) Tradeweb and leading broker dealers will use an agreed standardized aggregated cash flow approach for calculating yields, spreads and duration, as well as other metrics to evaluate and quote fixed income ETFs such as yields, spread and duration. This will allow fixed income investors to analyze fixed income ETFs using the same metrics that are used for other bond and derivative products.

“Developing a global market standard for bond ETFs is critical for the future evolution of fixed income markets. Agreeing to a common language and framework improves investors’ ability to analyze bond ETFs relative to other fixed income instruments. This creates exciting new opportunities for bond investors to accelerate their use of ETFs,” said Mark Wiedman, Global Head of iShares at BlackRock.

Fixed income ETFs are diversified portfolios of physical bonds that trade on an exchange. Since inception in 2002, the products have grown rapidly, with an aggregate value of over $450B globally. However, global fixed income ETF assets still only represent less than 0.4% of the total fixed income market.

"While the growth of fixed income ETFs has been substantial in recent years, the institutional participation in this market has been slow to develop. One factor hindering institutional adoption has been the lack of standardization of a yield and spread calculation," said Ben Macdonald, Bloomberg's Global Head of Product. "In the future, we expect to see greater exposure to fixed income ETFs by institutional investors, and we have worked with the industry to develop this new methodology and the tools to help our customers identify investing opportunities."

“Fixed income ETFs are in their early stages of growth as investors become better acquainted with their ability to provide efficient access to the global bond markets and their emergence as an indispensable portfolio management tool,” said James Ross, executive vice president and global head of SPDR Exchange Traded Funds at State Street Global Advisors. “Establishing a standard fixed income ETF methodology for the calculation of yields, spreads and durations supports their growing importance while helping investors make more accurate product comparisons and improve portfolio construction.”

The move to enable ETF usage comes at a time when institutional investors are increasingly turning to ETFs for a variety of fixed income portfolio needs, including cash management and liquidity management.

“Since fixed income ETFs are increasingly being priced by bond desks, this initiative will make it considerably easier for traders to analyze and value these products”, said Lee Olesky, CEO Tradeweb Markets. “Almost a third of our ETF volume is in fixed income-based products, and we see great potential for this segment of the market. This is an important initiative for the ETF industry, and another factor that will improve the market’s ecosystem and contribute to its growth.”

"In an environment with increasing capital requirements and constraints, investors are hungry for alternatives like fixed income ETFs to help them source liquidity. Standardization of key metrics is a critical precondition for fixed income products that trade more like equities," said Brian Levine, head of Cross-Asset ETF products and co-head of Global Equites Trading at Goldman Sachs.

Upon launch in the fall, fund information for iShares and SPDR single-currency fixed income ETFs will be available using this new standard, with Bloomberg, Tradeweb, and BlackRock’s risk and enterprise investment system Aladdin®, each displaying risk metrics through their analytics, trading, and investment platforms. The risk metrics will also be accessible from and
