Dear Dr. Don,
Have the savings bond purchase limits changed for 2011? My bank has refused my request to purchase a $5,000 I bond because they say I already have purchased the maximum in electronic I bonds via TreasuryDirect.

Dear Kenneth,

The savings bond purchase limit changed as of Jan. 1, 2008. The Treasury press release on the annual purchase limit for savings bonds being set at $5,000, explains it in greater detail, and it explains how you can finesse the issue to buy more Series I bonds as excerpted below.

The limit applies separately to Series EE and Series I savings bonds, and separately to bonds issued in paper or electronic form. Under the new rules, an individual can buy a maximum of $5,000 worth of electronic and paper bonds of each series in a single calendar year, or a total of $20,000, in single ownership form. If paper bonds are issued in co-ownership form, the limit applies to the first-named co-owner. All limits are based on the issue price of the securities.

Also, check out an earlier column on getting around the Series I-bond limit. It points out that you can convert the paper bonds you purchase to electronic form without violating the annual purchase limits and how Treasury inflation-protected securities, or TIPS, are a way to gain inflation-protected yields without the purchase limitations placed on savings bonds.

The Treasury just announced the yields currently available on Series I and Series EE savings bonds. Series I savings bonds purchased over the next six months will earn a fixed rate of zero percent over the bond's 30-year life and an inflation component of 4.6% over the first six months. The inflation component yield changes every six months based on changes in the Consumer Price Index.
