PROSPECTUS SUPPLEMENT DATED JANUARY 2, 2002
(TO PROSPECTUS DATED SEPTEMBER 4, 2001)

                             WASHINGTON MUTUAL, INC.

               Trust Preferred Income Equity Redeemable Securities
                                  (PIERS) Units

This document  supplements the prospectus  dated September 4, 2001,  relating to
the units. Each unit consists of:

o    a preferred  security  issued by Washington  Mutual Capital Trust 2001 (the
     "Trust"),  having a  stated  liquidation  amount  of $50,  representing  an
     undivided  beneficial  interest  in the assets of the Trust,  which  assets
     consist solely of subordinated debentures issued by Washington Mutual, Inc.
     each of which has a principal  amount at maturity of $50, a stated maturity
     of July 1, 2041 and, at any time,  an accreted  value as  described  in the
     prospectus; and

o    a warrant to  purchase at any time prior to the close of business on May 3,
     2041,  1.2081  shares of common stock of  Washington  Mutual.  The exercise
     price of each  warrant on the initial  date of issuance was $32.33 and will
     accrete  on a daily  basis as  described  in the  prospectus  to $50 on the
     expiration date.

At any time after  issuance of the units,  the  preferred  security  and warrant
components  of  each  unit  may be  separated  by  the  holder  and  transferred
separately.  Thereafter,  a  separated  preferred  security  and  warrant may be
combined to form a unit.

The information in this  prospectus  supplements the information set forth under
the heading "Selling Securityholders" in the prospectus dated September 4, 2001.
Jefferies & Company, Inc. is added to the list of Selling  Securityholders,  and
