The fund tracks the ICE US Treasury Inflation-Linked Bond Index and holds US Treasury Inflation-Protected Securities (TIPS) with more than one year to maturity, weighted by market capitalization. Because principal is linked to the Consumer Price Index, the real value of the holdings adjusts when inflation rises.

It is suited to medium- and long-term bond investors who want protection against inflation risk while keeping the safety of US Treasuries.

It is a passively managed (index-tracking) ETF run by BlackRock (iShares).

The fund holds the US inflation-protected Treasuries included in the index at their index weights, tracking the real return linked to inflation. Because principal is adjusted according to the price index, increases in inflation are reflected in principal, unlike nominal Treasuries, and the portfolio is refreshed regularly to maintain a medium-term average maturity.

• An inflation-hedging structure in which principal is linked to the Consumer Price Index
• High credit safety based on Treasuries issued by the US Department of the Treasury

Assets under management (AUM) are $14.6B, and the expense ratio is 0.18% per year.

Compared with similar ETFs such as SCHP and STIP, it differs in expense ratio and average maturity composition, which results in different interest rate sensitivity.

Given the nature of inflation-protected Treasuries, the price moves with inflation expectations and changes in real interest rates. It tends to face downward price pressure when real rates rise and to show relative strength when inflation expectations rise.

Funds tend to flow in as hedging demand when inflation concerns come to the fore, while preference over nominal Treasuries has been observed to weaken when prices are stable. The direction of interest rate policy is the main variable behind fund flows.

Its strengths are the inflation hedge and Treasury credit safety, while its weaknesses are price declines when real rates rise and softness during deflationary periods.

SCHP and STIP, shown in the table, are comparison candidates in the same inflation-protected Treasury category. Among them, SCHP is a direct substitute that tracks at a lower expense ratio, and STIP is a variant that concentrates on short maturities to reduce interest rate sensitivity. TDTT and TDTF use a structure with a fixed target duration, and DFIP differs in that it is actively managed. If you also want nominal Treasury exposure, you can consider IEF, an intermediate-term Treasury ETF, and if you want to focus more on short-term inflation protection, VTIP is also worth reviewing.

These are the points to review before investing in TIP. Although it is an inflation-hedging bond fund, the direction of real interest rates, the interest rate sensitivity that comes from average maturity, and the currency exposure for investors holding in Korean won should all be confirmed before buying.

Rising real interest rates and deflationary periods are the main drivers of price declines. Even an inflation-hedging asset can suffer short-term losses depending on the interest rate environment, so the holding period and purpose should be clearly defined.

It is suitable as a core holding for bond investors who want protection against inflation. If cost is the priority, SCHP is an option, and if you want lower interest rate sensitivity, short-term products such as STIP and VTIP can be alternatives.
