Please note that your investment in Smith Barney Money Funds is neither insured

the Smith Barney Money Funds will be able to maintain a stable net asset value
("NAV") of $1.00 per share.

Market Update and Outlook

Asset growth for the taxable money fund industry was once again stellar. The
industry grew 12.8% over the last six months. The Cash, Government and
Retirement Portfolios participated in that increase with a combined growth rate
of 



- ----------
*    The effective yield is calculated similarly to the seven-day yield but,
     when annualized, the income earned by an investment in a Portfolio is
     assumed to be reinvested. The effective yield will be slightly higher than
     the seven day yield because of the compounding effect of the assumed
     reinvestment.

16.6%. As of June 30, 1998, the Cash Portfolio is the second largest money
fund in the mutual fund industry with assets of $34.3 billion. The Government
Fund is the third largest government money market fund with assets of $4.8
billion. We believe that the generous returns in the stock market have allowed
for large gains in disposable income that have been in turn, invested, in money
market funds.

As we enter the second half of 1998, the U.S. economy's expansion remains
intact. Strong consumer demand has fueled the U.S. economy for six straight
quarters with 3.0% or better Gross Domestic Product ("GDP") growth. (GDP
measures the total output of goods and services.) With little or no evidence of
inflation, the Federal Reserve Board ("Fed") has been able to keep the
federal-funds rate steady at 5.50% since March 1997. (The federal-funds rate is
the interest rate banks charge each other for overnight loans and is a closely
watched indicator of the direction of interest rates.) However, robust
employment gains and the fear of higher wage pressures have kept the Fed on
alert.

Counteracting strong U.S. economic growth are pressing questions from abroad.
The Asian crisis (i.e., economic and currency problems in Indonesia, Thailand,
South Korea and other parts of the region) has finally started to negatively
affect the U.S. trade balance. Moreover, Japan's severe banking problems will
not go away and the Japanese economy continues to teeter on the brink of
depression. In addition, the future of Russia's economy remains cloudy at best.

Due primarily to the extraordinary strength of the U.S. economy, Fed Chairman
Alan Greenspan shifted monetary policy from a neutral stance to a tightening
bias at the March 31, 1998 Federal Open-Market Committee Meeting. (The Federal
Open-Market Committee or FOMC, is the committee that sets interest rates and
credit policies for the Federal Reserve System.) However, the apparent lack of
inflation has given Chairman Greenspan the opportunity to take a "wait and see"
approach with respect to monetary policy. The major fear in the markets now is
that a pre-emptive strike versus inflation could cause serious ramifications in
the already unsettled Asian countries. Record inventory accumulation in the
first quarter of 1998 along with the problems abroad should help to moderate
U.S. economic growth and allow Greenspan to hold rates steady in the months
ahead.

Effective July 1, 1998, the Securities and Exchange Commission ("SEC") has
adopted new rules that tighten risk exposure and necessitate additional
monitoring of bank and insurance guarantees and obligor concentrations with
respect to asset-backed commercial paper. (Asset-backed commercial paper
reflects cash flows from various types of receivables, and is generally
accompanied by a partial guarantee.) All of our guarantors are rated either
A1/P1 or better by Moody's Investors Services, Inc. or Standard and Poor's
Ratings

Service, two major credit reporting and bond rating agencies. Any concentrations
or obligors within asset-backed programs will meet the same stringent credit
standards as we generally employ before we make any purchase. We believe the new
SEC rules will further strengthen the overall quality of the money market fund
industry.

Investment Strategy

As noted, we think that many more months of strong U.S. economic growth or
higher-than-expected inflation numbers are necessary for the Fed to raise rates.
Therefore, we are taking advantage of the positively sloping yield curve and
targeting the average maturity at 80 days for the Cash Portfolio and 70 days for
the Government and Retirement Portfolios. (The yield curve shows the difference
between short- and long-term yields. A positively sloping yield curve means that
investors are being compensated with higher yields for the extra market risk
associated with owning longer-maturity securities.) Some of our banking and
corporate names were eliminated during the reporting period. As replacements, we
are planning to add some top-tier corporate names such as SBC Communications
Inc., GTE Corp, Ameritech Capital Funding Corp., and Province De Quebec to the
approved list.

In closing, thank you for investing in the Smith Barney Money Funds, Inc. We
look forward to continuing to help you pursue your financial goals.

Sincerely,


/s/ Heath B. Mclendon                    /s/ Phyllis M. Zahorodny

1. Significant Accounting Policies

Smith Barney Money Funds, Inc. ("Fund"), a Maryland corporation, is registered
under the Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund consists of three separate investment
portfolios ("Portfolios"): the Cash Portfolio, the Government Portfolio and the
Retirement Portfolio.

The significant accounting policies consistently followed by the Fund are: (a)
transactions in money market instruments and government obligations are
accounted for on trade date; (b) the Fund uses the amortized cost method for
valuing investments; accordingly, the cost of securities plus accreted discount,
or minus amortized premium, which approximates value; (c) interest income is
recorded on the accrual basis; (d) direct expenses are charged to each Portfolio
and each class; management fees and general fund expenses are allocated on the
basis of relative net assets; (e) gains or losses on the sale of securities are
calculated by using the specific identification method; (f) the Portfolios
intend to comply with the applicable provisions of the Internal Revenue Code of
1986, as amended, pertaining to regulated investment companies and to make
distributions of taxable income sufficient to be relieved from substantially all
Federal income and excise taxes; and (g) estimates and assumptions are required
to be made regarding assets, liabilities and changes in net assets resulting
from operations when financial statements are prepared. Changes in the economic
environment, financial markets and any other parameters used in determining
these estimates could cause actual results to differ.

2. Dividends

Each Portfolio declares and records a dividend of substantially all of its net
investment income on each business day. Such dividends are paid or reinvested
monthly in each respective Portfolio's shares on the payable date.

3. Management Agreement and Other Transactions

Mutual Management Corp. ("MMC"), a subsidiary of Salomon Smith Barney Holdings,
Inc. ("SSBH"), acts as investment manager to the Fund. As compensation for its
services, each Portfolio pays MMC a daily fee calculated at the following rates:
Cash Portfolio: 0.45% on the first $6.0 billion of average daily net assets,
0.425% on the next $6.0 billion, 0.40% on the next $6.0 billion and 0.35% on the
average daily net assets in excess of $18.0 billion; Government Portfolio: 0.45%
on the first $2.5 billion of the average daily net assets, 0.40% on the next
$2.5 billion and 0.35% on average daily net assets in excess of $5.0 billion;
and Retirement Portfolio: 0.45% on the first $1.0 billion of average daily

net assets, 0.40% on the next $1.0 billion and 0.35% on average daily net assets
in excess of $2.0 billion. These fees are calculated daily and paid monthly.

Pursuant to a Distribution Plan, each Portfolio makes payments to Smith Barney
Inc. ("SB"), another subsidiary of SSBH, for assistance in distributing Class A
and L shares, calculated at an annual rate of 0.10% of average daily net assets
of each class, respectively. For the six months ended June 30, 1998, total
Distribution Plan fees incurred were:

All officers and one Director of the Fund are employees of SB.

4. Capital Loss Carryforward

At December 31, 1997, the Cash Portfolio had, for Federal tax purposes,
approximately $1,344,000 of capital loss carryforwards available to offset
future capital gains. To the extent that these carryforward losses are used to
offset capital gains, it is probable that the gains so offset will not be
distributed. The amount and expiration of the carryforwards are indicated below.
Expiration occurs on December 31 of the year indicated:

5. Repurchase Agreements

The Fund purchases (and its custodian takes possession of) U.S. government
securities from banks and securities dealers subject to agreements to resell the
securities to the sellers at a future date (generally, the next business day) at
an agreed-upon higher repurchase price. The Fund requires continual maintenance
of the market value of the collateral in amounts at least equal to the
repurchase price.

6. Capital Shares

The Fund has multiple classes of shares within the Cash and Government
Portfolios. Class A and Class Y shares can be purchased directly by investors;
Class L shares can only be purchased by participants in the Smith Barney 401(k)
Program; and, Class Z shares can only be purchased by participants in the Smith
Barney Employee 401(k) Program. Effective June 12, 1998, the Fund adopted the
renaming of existing Class C shares as Class L shares.

Proposal 2 requested that shareholders approve certain changes to the
fundamental policies of the Fund in order to modernize them in view of certain
regulatory, business or industry developments that have occurred since original
adoption of these policies by the Fund. The following chart demonstrates that
all proposals were approved by shareholders.

Please note that "M" indicates a modification of the policy; "E" indicates the
elimination of the policy; and "R" indicates the reclassification of the policy
from fundamental (which would require shareholder approval to change) to
non-fundamental (which can be changed by a vote of the Board of Trustees).
