What it means
Some financial contracts need a reference rate that blends two worlds. Indian banks hedging dollar-rupee exposures wanted a rate reflecting both dollar funding costs and the rupee forward market, and MIFOR supplied it: LIBOR plus the forward premium implied by currency swaps.
The construction made it a hybrid. Because the forward premium moves with interest rate differences between the two currencies, MIFOR effectively translated dollar rates into synthetic rupee terms.
Derivatives desks used it to settle forward rate agreements and swaps linked to that combined exposure. Its weakness was inherited.
MIFOR rested on LIBOR, and when global regulators moved to retire LIBOR after the rate-rigging scandal and the decline of the interbank market it measured, every benchmark built on LIBOR inherited the same end date. India's central bank told banks to stop writing new MIFOR contracts from the end of 2021, and Financial Benchmarks India, the administrator, published the final rates on 30 June 2023.
Existing contracts were left to mature or transition to replacement references. The MIFOR story is really the benchmark-reform story told through one rate.
References that thousands of contracts treat as bedrock can be discontinued when their foundations weaken, and the transition work of re-documenting portfolios is long and unglamorous. The episode also showed how much invisible plumbing a single rate supports.
MIFOR appeared in loan agreements, swaps, accounting systems and risk models, and each use had to be found, re-papered and tested before the final fixing. For treasurers and managers, the lesson endures beyond India.
Any contract referencing a benchmark should name what happens if that benchmark ceases, because cessation clauses written in calm times decide who bears the difference when the rate disappears.
In practice
Real-world examples.
Example
An Indian importer hedging a dollar loan enters a forward rate agreement referenced to MIFOR. The settlement reflects both dollar interest costs and the rupee forward premium at the fixing date. The importer's finance team records the fixing in its hedge accounting file.
Example
A derivatives desk holds MIFOR swaps maturing after June 2023. Its transition team repapers the portfolio to replacement rates over eighteen months, adjusting spreads so neither side gains or loses from the switch. Each trade is tested against the old fixings before it is signed off.
Example
A treasurer checks a 2019 facility agreement and finds the fallback clause names a replacement rate and spread adjustment, so the MIFOR cessation changes the paperwork but not the economics. She files a note confirming that no further action is needed.
Formula
Calculation
MIFOR approximated LIBOR + forward premium, where the forward premium reflects the interest differential between rupees and dollars for the same period. If six-month LIBOR was 5.2% and the forward premium added 1.8%, six-month MIFOR fixed near 5.2% + 1.8% = 7.0% until the methodology's final publication.
On a $10,000,000 notional for six months, 7.0% implies interest of $10,000,000 x 7.0% x 0.5 = $350,000. In a transition, suppose the replacement reference rate fixed at 5.0% and the parties agreed a fixed spread adjustment of 2.0%. The all-in rate stays 5.0% + 2.0% = 7.0%, so the interest remains $350,000 and neither side gains or loses from the switch on that date.Case study
Seen in the real world.
Fictional example: Dhruva Textiles, an imagined exporter, borrowed dollars and hedged with MIFOR-linked swaps through the 2010s, barely noticing the reference rate in its documents. When the cessation was announced, its bank sent a transition proposal for every contract. The fictional finance head initially signed without reading, until her adviser modelled the spread adjustment and found one swap priced noticeably against her. Renegotiated with market-standard fallbacks, the portfolio transitioned with a small one-off cost. The episode rewrote house policy: no contract is signed now until someone has read the clause that says what happens when the benchmark dies.
Watch out
Common mistakes.
- Assuming published benchmark rates are permanent features of markets, when administrators and regulators can and do discontinue them.
- Ignoring fallback and cessation clauses when signing contracts, since those clauses decide the economics and the paperwork burden if the reference rate vanishes.
- Believing MIFOR still fixes today, when publication ceased on 30 June 2023 and legacy contracts have matured or transitioned.
Questions
People also ask.
Does MIFOR still exist?
No. Financial Benchmarks India published the final MIFOR rates on 30 June 2023, after the Reserve Bank of India directed banks to stop new MIFOR contracts from the end of 2021. It survives only as a historical reference in matured contracts.
Why was MIFOR discontinued?
It was built on US dollar LIBOR, which global regulators retired after the manipulation scandal and the decline of underlying interbank trading. Benchmarks derived from LIBOR shared its end date.
What replaced rates like MIFOR?
Contracts moved to alternative reference rates built on actual transactions, such as overnight risk-free rates in each currency, with spread adjustments to mirror the old economics as closely as possible.
