What are the Rules of Finance in Islam?
Islamic finance is built on ethical and asset-backed principles. The system prohibits interest (riba), excessive speculation (gharar), gambling (maisir), and inversiones in haram sectors such as alcohol, pork, and adult entertainment.
All financial transactions should be backed by real economic activity, and profit must be earned through shared risk, trade, or value creation.
For international investors, this means selecting instruments that generate returns through rental income, profit-sharing, commodity trades, or equity participation rather than fixed interest.
Islamic finance also emphasizes fairness, transparency, and long-term financial stability, aligning well with HNWIs seeking balanced and ethical portfolios.
What is the 30% Rule in Islamic Finance?
The 30 rule in Islamic finance means a company is only considered halal if its interest-bearing debt stays below 30 percent of its market capitalization.
This benchmark helps investors avoid firms that rely heavily on conventional borrowing and ensures the balance sheet aligns with Shariah limits on riba.
For expats and high-net-worth investors, the rule serves as a practical screening tool when assessing global equities and Islamic ETFs.
It supports the broader principles of Islamic finance, which require avoiding excessive uncertainty, interest-driven income, and financial structures built on prohibited funding sources.
Although the exact methodology can vary across Shariah boards, the 30% threshold is consistently applied by major standards such as MSCI Islamic and Dow Jones Islamic Indexes.
Knowing how this ratio works makes it easier for international investors to determine whether acciones and funds qualify as Shariah-compliant.
What is the Debt Ratio in Halal?
The debt ratio in halal investing refers to the acceptable level of interest-bearing debt a company can have while remaining Shariah-compliant.
The most recognized standard is the 30% threshold, which matches the 30% rule in Islamic finance.
This means a company’s interest-based liabilities should not exceed 30% of its market cap.
Some Shariah boards apply the ratio to total assets instead of market cap, but the objective is the same; preventing excessive reliance on interest-based financing.
This filter helps investors avoid companies that may be overly exposed to financial instability or inconsistent with Shariah principles.
What are the Rules for Islamic Loans?
Islamic loans must avoid interest, so they are structured through alternative mechanisms such as murabaha (cost-plus financing), ijara (leasing), or diminishing musharaka (partnership-based home financing).
Instead of charging a traditional interest rate, the bank sells an asset at a disclosed markup or shares profits and risks with the client.
For expats buying property abroad, Islamic mortgages often involve the bank purchasing the property first and then leasing it to the client until ownership is fully transferred.
These structures create fixed, transparent payments without violating Shariah rules.
Is 1% Interest Halal?
Even a small amount of guaranteed interest, whether 1% or less, is considered riba and therefore haram.
The percentage does not change the ruling. Any guaranteed increase on a loan qualifies as interest, regardless of how minimal it seems.
In practice, many Muslims and Shariah-conscious investors avoid conventional savings accounts, bonds, and interest-bearing loans and instead use Islamic banking products with profit-sharing or trade-based structures.
Expat investors often opt for sukuk (Islamic bonds) or Islamic money market funds for low-risk allocation without interest exposure.
What are the Advantages and Disadvantages of Islamic Finance?
The main advantage of Islamic finance is its ethical, interest-free structure, while its main disadvantage is the limited availability of Shariah-compliant products in many markets.
This ethical framework appeals to HNWIs who prioritize transparency, fairness, and investments backed by real economic activity.
It also helps reduce exposure to excessive speculation and highly leveraged companies.
However, access remains uneven across countries, and differences in Shariah interpretations can complicate product selection.
Expat investors often need specialized advice to evaluate global equities, ETFs, and sukuk products under varying screening standards.
Conclusión
The 30% rule remains one of the most practical tools for identifying Shariah-compliant investments in global markets.
For expats and high-net-worth individuals, it provides a clear starting point when evaluating equities, ETFs, and structured Islamic products across different jurisdictions.
While interpretations vary slightly among scholars, the underlying goal is consistent: ensuring that wealth is built through ethical, asset-backed activity rather than interest-based financing.
Understanding how these standards work in practice allows investors to navigate international opportunities with confidence and align their portfolios with both financial objectives and Islamic principles.
