Both of these ETFs limit their purchases to treasury securities issued in foreign developed markets. IGOV has a weighted average maturity of about eight years, and is therefore similar to SPDR Barclays Capital International Treasury Bond ETF (BWX). IGOV concentrates its holdings in 1-3 year securities, making it a short-term offering that is likely to be more sensitive to currency fluctuations than interest rate changes.

Neither ETF had any trades today, but the bid/ask data suggests that IGOV should start trading at around $96 per share and ISHG at $94.

Further information on the underlying indexes for these two ETFs indicates that data prior to October 31, 2008 are pro-forma.
