To achieve this expense cap, BlackRock has agreed to waive and/or reimburse fees and/or expenses if the Fund’s annual fund operating expenses, excluding certain expenses described in the prospectus, exceed a certain limit for the Fund’s Class K Shares. Accordingly, the Fund’s Prospectus is amended as follows:

The section of the Fund’s Prospectus entitled “Fund Overview — Key Facts About BlackRock Strategic Global Bond Fund, Inc. — Fees and Expenses of the Fund” is deleted in its entirety and replaced with the following:

¹  Management Fee restated to reflect current fees.

²  Interest Expense is based on estimated amounts for the current year.

³  The Strategic Global Bond Fund (Cayman) (the “Subsidiary”) is newly organized and, accordingly, Other Expenses of the Subsidiary are based on estimated amounts for the current fiscal year of less than 0.01%.

⁴  The Total Annual Fund Operating Expenses do not correlate to the ratios of expenses to average net assets given in the Fund’s most recent annual report, which do not include Acquired Fund Fees and Expenses or the restatement of the Management Fee and Interest Expense to reflect current fees.

⁵  As described in the “Management of the Fund” section of the Fund’s prospectus beginning on page 29, BlackRock Advisors, LLC (“BlackRock”) has contractually agreed to waive and/or reimburse fees or expenses in order to limit Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements (excluding Dividend Expense, Interest Expense, Acquired Fund Fees and Expenses and certain other Fund expenses) to 0.54% of average daily net assets through April 30, 2018. The contractual agreement may be terminated upon 90 days’ notice by a majority of the non-interested directors of the Fund or by a vote of a majority of the outstanding voting securities of the Fund.

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year		3 Years		5 Years		10 Years
Class K Shares	$	59	$	283	$	525	$	1,219

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 477% of the average value of its portfolio.

The table immediately following the eighth paragraph in the section of the Prospectus entitled “Management of the Fund — BlackRock” is deleted in its entirety and replaced with the following:

Shareholders should retain this Supplement for future reference.
