DWS Strategic Municipal Income Trust (KSM) Declares a Monthly Distribution

NEW YORK--(Business Wire)--
DWS Strategic Municipal Income Trust (NYSE: KSM) declared a
monthly distribution of $0.055 per common share, payable on June 30,
2008 to shareholders of record on June 16, 2008. The ex-date is June
12, 2008. The previous monthly distribution was $0.055 per share.

The current distribution rate represents a 5.70% annualized yield
based on the closing market price of $11.58 on June 5, 2008 and a
5.64% annualized yield on a closing NAV of $11.70 on the same date.

Future earnings cannot be guaranteed and the Fund's distribution
policy is subject to change. For more information on KSM please

DWS Strategic Municipal Income Trust seeks a high level of current
income exempt from federal income tax by investing in a diversified
portfolio of investment-grade tax-exempt securities. The fund will
invest at least 50 percent of its assets in investment-grade municipal
securities or unrated municipal securities of comparable quality, and
may invest up to 50 percent of its assets in high-yield municipal
securities that are below investment grade. The fund invests in
individual bonds whose yields and market values fluctuate, so that
your investment may be worth more or less than its original cost.
Additionally, although the fund seeks income that is federally
tax-free, a portion of the fund's distributions may be subject to
federal, state, local and alternative minimum tax. Bond investments
are subject to interest-rate risk such that when interest rates rise,
the prices of the bonds, and thus the value of the bond fund, can
decline and the investor can lose principal value.

Investments in closed-end funds involve risk. Closed-end funds,
unlike open-end funds, are not continuously offered. There is a
one-time public offering, and once issued, shares of closed-end funds
are sold in the open market through a stock exchange. Shares of
closed-end funds frequently trade at a discount to net asset value.
The price of the Fund's shares is determined by a number of factors,
several of which are beyond the control of the Fund. Therefore, the
Fund cannot predict whether its shares will trade at, below or above
net asset value.

Past performance is no guarantee of future results. Annualized
yield is the latest monthly distribution shown as an annualized
percentage of net asset value/market price at month end. Annualized
yield simply measures the level of distribution and is not a complete
measure of performance. Market price, annualized distribution yield,
net asset value are historical and will fluctuate and do not guarantee
future results.

This announcement is not an offer to purchase or the solicitation
of an offer to sell shares of the Fund or a prospectus, circular or
representation intended for use in the purchase or sale of Fund
shares.
