Portfolio Rebalancing in 2026: Understanding the 10% Gold Rule

The year 2025 saw a sharp increase in gold prices, with prices for 10 grams of 24-karat gold crossing ₹1.2 lakh in October. Prices continued to climb into 2026, with gold crossing ₹1.5 lakh per 10 grams. This surge has gradually shifted gold from being seen primarily as an emotional investment to being considered an important financial asset for portfolio diversification. 

While the rising interest in gold investments may be recent, financial planners have long suggested adding a modest portion of this shining metal to a portfolio, often referred to as the 10% gold rule. This blog explains what portfolio rebalancing is, why gold can be part of a portfolio, and how much weight it may carry. 

What is portfolio rebalancing?

Portfolio rebalancing is the process of adjusting your asset allocation from time to time to maintain your desired investment mix. It typically involves selling assets that have gone beyond their target allocation and buying underweighted assets in the portfolio. Doing so ensures that your portfolio stays aligned with your risk appetite and financial goals. 

For instance, suppose Mohit is a 50-year-old conservative investor. As a simple rule of thumb, he may allocate 50% to equities and the remaining 50% to other assets, like debt and gold, to balance overall portfolio volatility. Now, if equities perform well and equity allocation increases to 70%, his portfolio may become riskier than intended. In such a case, he may sell a portion of equities and reallocate the proceeds to other assets to restore the original balance. 

It is important to note that portfolio rebalancing is not a one-time exercise. It should be done regularly because markets are dynamic. Investors typically rebalance their portfolios annually or semi-annually, or when markets are highly volatile, causing asset allocation to deviate significantly from the preset limit.

With gold being an increasingly talked-about asset class in 2026, this may be a good time for investors to review and rebalance their portfolios. 

Why do investors include gold in their portfolio?

With the easy availability of digital gold investment options, gold is no longer seen solely as an adornment in Indian households. 

Here are some reasons why including gold in a portfolio may make sense: 

1. Diversification: Gold can help diversify an equity-heavy portfolio. This is because gold typically has a low or negative correlation with equities. This means that when stock markets decline, gold’s price may remain stable or sometimes even increase. 
2. Liquidity: Unlike some investments, such as real estate, gold—particularly in financial forms such as Exchange-Traded Funds (ETFs) and digital gold—offers relatively higher liquidity. This also makes portfolio rebalancing easier. For example, you can sell a gold ETF on the stock exchange during trading hours just like stocks.
3. Ease of investing: Both physical and digital gold can be purchased relatively easily without complex procedures. Investment options such as gold mutual funds can be bought online within minutes.
4. Inflation hedge: Gold has historically been considered an inflation hedge. While cash and fixed-income investments may lose purchasing power over time, gold has often performed relatively well during periods of high inflation or currency depreciation. 
5. Safe-haven asset: During crises such as geopolitical instability or recessions, gold is often viewed as a safe-haven asset due to its perceived intrinsic value.

With so many advantages, including gold in a portfolio may make sense. The next question is: how much gold should you allocate?

What is the 10% gold rule?

The 10% gold rule is a commonly accepted thumbrule suggesting that investors allocate about 10% of their long-term portfolio to gold. The idea is to maintain a diversified portfolio that can withstand market volatility without significantly reducing exposure to growth-oriented assets, such as equities. When equity markets are volatile, gold may offer relative stability.

For example, if your investment portfolio is worth ₹5 lakh, allocating about ₹50,000 to gold or gold-related investments would align with the 10% gold rule. 

It is worth noting that the 10% gold rule is a general guideline and not a strict rule. The actual gold allocation should depend on factors such as risk tolerance, financial goals, investment horizon, and liquidity needs. 

What are types of gold investments?

Investors have several options to include gold in their portfolio in 2026:  

1. Physical gold: This includes jewellery, gold coins, and bars. This traditional form of gold investment may involve high making charges in the case of jewellery and additional concerns related to storage and security. 
2. Gold ETFs: Gold ETFs track the price of domestic gold. Each unit of a gold ETF typically represents 1 gram of gold with 99.5% purity. They are traded on stock exchanges and require a demat and trading account.
3. Gold mutual funds: These are mutual fund schemes that invest primarily in gold ETFs. They offer gold exposure without the need for a demat and trading account.  
4. Digital gold: This is a way of buying gold online in small amounts. Every investment is backed by an equivalent quantity of 24-karat physical gold stored by the provider. Digital gold can be redeemed for physical delivery of gold.

When should gold allocation be higher or lower?

Gold allocation depends on both individual and market factors. Usually, a higher allocation to gold is recommended in periods of economic instability or high market volatility, as gold is often considered a safe-haven asset in such situations. On the other hand, the allocation may be reduced during stable or bullish market conditions, when investors may focus more on growth-oriented assets. 

The allocation can also depend on individual factors such as your age and risk appetite. For instance, if you are a young or aggressive investor, you may want to keep a modest exposure to gold in your portfolio.

How rebalancing impacts long-term returns?

Just as portfolio rebalancing is not a one-time activity, the benefits are also realised over the long term. 

1. Maintains target allocation: You determine a target allocation after carefully analysing your financial goals and risk profile. Periodic rebalancing ensures that your investments remain aligned with this target allocation over time.  
2. Better risk management: Effective risk management is essential for achieving long-term financial growth. Regular portfolio reviews and rebalancing help ensure that your risk exposure remains within acceptable limits. 
3. Encourages buying low and selling high: Portfolio rebalancing indirectly encourages you to sell assets that have appreciated significantly and buy assets that may be relatively undervalued. Over time, this approach helps capitalise on market fluctuations and improve portfolio performance.  
4. Exposure to diversified asset classes: When you rebalance your portfolio, you tend to consider multiple asset classes such as equities, debt, and gold. Gold is often considered to be a good hedge against inflation and can play a role in supporting long-term financial goals. 

Conclusion

Gold has been a traditional investment in Indian households for decades. However, in recent years, the way people invest in gold has evolved. Regardless of the investment type, maintaining the right proportion of gold in the portfolio may help create a cushion against market volatility and support overall portfolio diversification.
