Is Earning Interest During High Inflation Permissible? The 2020s Debate

Between 2021 and 2024 a lot of Muslims watched their savings quietly shrink. US CPI ran past 9% in mid-2022, Turkey's official rate went above 80% in late 2022, Egypt's crossed the mid-30s in 2023, and Argentina spent a stretch above 200% year over year. At the same time, the Fed pushed its policy rate over 5% and money market funds started paying roughly that. So the question landed in a lot of inboxes at once: if the cash in your account is losing purchasing power every month, is earning interest during high inflation permissible as a way of standing still rather than getting richer?

The short answer from the large majority of contemporary scholars and standard-setting bodies is no. The interesting part is why, because the reasoning is more careful than "interest is haram, next question," and there is a real minority position worth understanding rather than dismissing.

What the source texts actually say

The prohibition sits in Surah al-Baqarah, verses 275 to 279. Verse 275 draws the line that everything else hangs on: Allah permitted sale (bay') and forbade riba. Verse 279 is the operative one for this debate. After warning those who persist, it tells anyone who repents that they have their ru'us amwalikum, their capital sums, and adds a two-way clause: you do no wrong and you are not wronged (la tazlimuna wa la tuzlamun).

That clause is doing a lot of work in the inflation argument, and both camps cite it. The dominant reading is straightforward: the lender's entitlement is the principal, nothing above it, and taking more is the wrong being described. Surah Aal Imran 3:130 adds the prohibition on riba "doubled and multiplied," which some modern reformers read as targeting only compounding predatory loans, though the classical schools read it as describing pre-Islamic practice rather than narrowing the prohibition.

On the hadith side, the relevant category here is riba al-nasiah, riba of deferment, which is what any loan-with-return is. That is distinct from riba al-fadl, the excess in a hand-to-hand exchange of the six commodities named in the report of Ubada ibn al-Samit (gold, silver, wheat, barley, dates, salt: like for like, equal for equal, hand to hand). A bank paying you 5% on a deposit is a loan from you to the bank with a stipulated increase, so it falls squarely in the first category.

The maxim jurists actually apply is "every loan that draws a benefit is riba" (kullu qardin jarra naf'an fahuwa riba). Worth being precise: as a marfu' hadith its chain is weak, and it is more reliably traced as a statement of companions including Fadala ibn Ubayd. All four Sunni schools nonetheless adopted it as a settled legal maxim, so its authority comes from juristic consensus on the rule rather than from a strong isnad. Anyone telling you it is an airtight prophetic text is overstating it, and anyone dismissing the rule because the isnad is weak is ignoring how the schools actually derived it.

The mechanism: why a debt is nominal, not real

Here is the part most people skip. The inflation argument is not really about whether interest is prohibited. It is about whether money is measured in units or in purchasing power. If a debt is denominated in purchasing power, then charging inflation-plus-zero is just getting your capital back and 2:279 protects you. If a debt is denominated in nominal units, then anything above those units is the prohibited increase.

Classical fiqh already had this fight, using copper coinage (fulus), whose value moved around a lot more than gold and silver. The Hanafis separated three scenarios: kasad (the currency goes out of circulation entirely), inqita' (it becomes unobtainable), and rukhs or ghala' (it simply gets cheaper or dearer). On kasad the school split. Abu Hanifa held the debtor still discharges the debt with the same nominal amount. Abu Yusuf held the debtor owes the value as of the day the loan was contracted. Muhammad al-Shaybani held the value as of the day the currency collapsed.

Notice what none of them said. For plain rukhs, ordinary depreciation of the kind inflation produces, the reported position across the schools is that the debt is discharged by the same nominal amount. Money was treated as a fungible (mithli) good, and a mithli obligation is settled by its like in count, not by its market value. That classical framing is the actual load-bearing premise behind the modern rulings.

The OIC International Islamic Fiqh Academy in Jeddah took this up directly, first in its fifth session in Kuwait in 1988 on linking debts to a price index, and again in its twelfth session in Riyadh in 2000 on the effect of inflation on the settlement of debts. The Academy's position on both occasions was that deferred debts are settled by their nominal amount in the contracted currency, and that indexing an existing debt to a general price level is not permitted, since it converts the loan into a value-guaranteed instrument with a stipulated increase. The Academy did leave doors open at the contracting stage: parties can denominate in gold, in a harder currency, or in a specified commodity from the outset, because that changes what was lent rather than adding to what is owed.

AAOIFI's treatment of the defaulting debtor points the same direction. Under its standard on the procrastinating debtor, a penalty can be stipulated to deter delay, but the proceeds go to charity, not to the creditor. Even where the creditor has suffered a real, demonstrable loss from delay, the standard refuses to let compensation for time flow back to the lender. If genuine delay-loss cannot justify a creditor return, generalized currency depreciation is a weaker case, not a stronger one.

The strongest counterargument, taken seriously

The necessity case has three legs, and it is not frivolous.

Darura and hajah

The maxim from al-Suyuti's and Ibn Nujaym's al-Ashbah wa al-Naza'ir is that necessity permits the prohibited (al-darurat tubih al-mahzurat), grounded in 2:173 and 6:119, and there is a companion maxim that general or specific need can occupy the position of necessity. So the argument runs: a Turkish saver in 2022 watching 80% inflation faces destruction of his property, and preservation of property (hifz al-mal) is one of the five maqasid.

The counter is built into the same maxim set. Darura is bounded by "necessity is measured by its extent" (al-darura tuqaddar bi qadariha), and the classical bar for darura is compulsion at the level of life or limb, the standard example being eating carrion to avoid death. Losing real value on savings is a serious harm, but it is neither life-threatening nor unavoidable, and darura licenses a bounded act of consumption rather than voluntarily entering an ongoing riba contract with a renewable maturity. That last distinction is why most muftis who accept an emergency exception for, say, an interest-bearing mortgage in a country with no Islamic alternative still will not extend it to a savings account earning yield.

Zulm runs both ways

The second leg reads 2:279 symmetrically. If the creditor taking more is zulm, the debtor repaying a nominally identical but far less valuable sum is also zulm, and the verse forbids both. A minority of modern jurists, with the Syrian scholar Mustafa al-Zarqa the most cited among them, argued along these lines in favor of some form of indexation for severe currency deterioration. The majority answer is that the verse defines the creditor's entitlement as ru'us al-amwal, the capital sum, and that fiat money is precisely what the parties chose as the unit of account when they contracted, along with its known risks. There is also a practical objection the Academy leaned on: general price indices are estimates, they differ by basket and by methodology, and building a contractual increase on a disputed statistic reintroduces gharar alongside the riba problem.

The Al-Azhar fatwa

The third leg is the most institutionally serious. Muhammad Sayyid Tantawi, as Grand Mufti of Egypt in 1989 and later as Shaykh al-Azhar, issued rulings treating fixed-return bank deposits and government investment certificates as permissible, on the reasoning that the depositor is an investor whose return is agreed in advance with the bank acting as manager. In December 2002 the Islamic Research Academy at Al-Azhar issued a ruling along the same lines. That is a real institution and a real position.

It is also an isolated one, and it reversed Al-Azhar's own earlier direction, since the Second Conference of the Islamic Research Academy in Cairo in 1965 had declared interest on all types of loans to be riba. The OIC Fiqh Academy, the Islamic Fiqh Academy of the Muslim World League, AAOIFI, and the shariah boards of essentially every Islamic bank hold to the prohibition. The technical objection is that a pre-agreed fixed return on capital is definitionally not mudaraba, since mudaraba requires profit sharing by ratio with the capital provider bearing loss. Calling a deposit an investment does not change the contract's mechanics.

What to actually do about it

Preserving purchasing power and earning riba are not the same project, and the second is not the only route to the first.

• Own real assets. Shariah-compliant equities are claims on businesses that reprice their own output, which is the most direct inflation hedge available. Screened equity portfolios in the 2022 to 2024 stretch did what equities do: they moved with the real economy rather than with a nominal coupon.
• Sukuk, not bonds. Ijara sukuk pass through rental income from identified assets. The return is not a stipulated increase on a loan, and lease rentals in many structures reset periodically against a benchmark, so they are not frozen at issuance.
• Gold. The classical hedge, and the one the Fiqh Academy explicitly allowed parties to denominate in at the contracting stage. Physical or fully allocated, with immediate constructive possession, because deferred settlement in gold has its own riba al-fadl problem.
• Islamic deposit alternatives. Mudaraba-based investment accounts and commodity murabaha deposits at Islamic banks are profit-generating rather than interest-bearing, and their distributed profit rates rose alongside policy rates in the Gulf and Turkey during the tightening cycle.
• Purify what you cannot avoid. Many current accounts credit interest whether you asked for it or not, especially in Turkey and the Gulf. The standard guidance is to calculate it and give it away with no expectation of reward, and not to leave it sitting with the bank.

If you want to see how the underlying rules are applied to instruments rather than to your own account, the FaithScreener methodology documents where each threshold comes from.

How interest income shows up in screening

The same logic that governs your savings account governs the companies you own, which is where screening does the heavy lifting.

Under the AAOIFI standard, a company's interest-bearing debt must stay under 30% of market capitalization, its interest-bearing securities and cash under 30%, and its impermissible income, interest included, under 5% of total revenue. The index providers use similar structures with different denominators: Dow Jones Islamic Market and S&P use 33% against a trailing 24-month average market cap, while FTSE and MSCI use 33.33% against total assets, which makes the same company pass one screen and fail another depending on how its share price has moved.

Two things follow for an inflation-heavy period. First, when rates rise, corporate interest income rises with them, and cash-rich companies that sat comfortably under the 5% revenue threshold can drift over it without changing their business at all. That is one reason a screen is a recurring check rather than a one-time verdict. Second, the residual interest that passes under the threshold is not waived. It is purified, meaning you calculate the impermissible share of your dividend and give it away. You can compare how the multi-faith frameworks handle the same balance sheet, since Christian BRI and Catholic USCCB screens weight leverage and interest very differently, and then run a specific ticker to see the ratios rather than guessing at them.

The Bottom Line

Inflation makes holding cash expensive, and the fiqh does not treat that expense as a reason to permit a stipulated return on a loan. The classical treatment of currency depreciation as rukhs rather than kasad, the OIC Fiqh Academy's rulings against indexing debts in 1988 and 2000, and AAOIFI's refusal to let even genuine delay-loss flow back to a creditor all point the same way, and darura does not reach a savings decision when halal alternatives exist. The one thing to hold onto: the problem is a stipulated increase on a loan, so the solution is to stop lending and start owning, because equity, real assets, and lease-based sukuk carry real returns without carrying riba.
