USD to INR Rate Hits New Low at 90; Here’s the Full Story Explained

The day began like any other, until the numbers glowed red. As markets opened on December 3, 2025, the Indian Rupee (INR) tumbled past the historic ₹90 per US Dollar (USD) threshold. For many, that “90 for a dollar” felt more psychological than material but the consequences ripple far beyond psychology. From import costs and overseas tuition to inflation and travel expenses, the fall of the rupee could reshape the financial reality of ordinary Indians.

Let's break down with this blog what propelled the rupee’s slide, how the Reserve Bank of India (RBI) is reacting, what experts foresee, and why this drop isn’t just about interest-rate differentials.

Why Did INR Fall?

The rupee’s plunge past ₹90 was not a freak one-day event, but the culmination of a series of pressures, both global and domestic.

• Capital outflows and weak foreign flows: 2025 has seen a steady withdrawal by foreign investors from Indian equities, with net outflows crossing the USD 17 billion mark. This flight of capital erodes demand for rupees and pushes up demand for dollars.
• Trade deficit and import bill surge: October’s merchandise trade deficit ballooned to around USD 42 billion, driven by falling exports and rising imports, especially from oil, metals, and bullion. As importers scrambled for dollars, the pressure on INR intensified.
• Global dollar strength and risk-off mood: With the dollar remaining firm globally, and investors chasing dollar-denominated assets amid risk aversion, emerging market currencies like INR are bearing the brunt. 
• Uncertainty around India-US trade deal and tariffs: Prolonged delays in concluding a favourable trade agreement, combined with steep US tariffs on Indian exports, have hurt export volumes and dampened outlook which is a blow to both trade balance and investor sentiment.

In short, the rupee didn’t fall for just one reason, but a perfect storm of foreign-capital withdrawal, deteriorating trade dynamics, and global dollar strength.

What Is the RBI Doing or Choosing Not to Do?

Though the rupee’s slide has drawn attention, the RBI’s response has been cautious and calibrated. Rather than aggressively defending a particular exchange rate, the RBI appears focused on mitigating excessive volatility.

In recent weeks, the RBI intervened intermittently by mostly selling dollars to stem rapid depreciation, especially when rupee neared record lows.

However, RBI’s stance seems to accept a certain degree of rupee weakness signalling that the exchange rate will be determined largely by market forces.

What’s Ahead for USDINR?

Even as some expect the rupee to stabilise, many analysts warn of further downside risks. The combination of persistent trade deficit, capital outflows and global dollar strength may push USD/INR beyond ₹91 in 2026 if external pressures continue.

That said, there are a few guard-rails: India’s macro fundamentals remain relatively resilient as GDP growth is robust and inflation has remained muted (CPI inflation has stayed low in recent months).

Some experts expect a period of consolidation, basically a “range-bound” INR between ₹89-₹91 unless there’s a significant change in trade flows or global dollar strength subsides.

Interest Rate, Inflation And Demand & Supply Angle on USDINR

Traditionally, exchange-rate movements reflect interest-rate and inflation differentials between countries as per Interest Rate Parity and Purchasing Power Parity. A higher interest rate in the US makes dollar assets more attractive and a higher US inflation can weaken the dollar relative to currencies whose countries have lower inflation, and vice versa. 

But this time, there’s something different. Even though India’s domestic inflation has remained modest and stable in 2025 which under normal circumstances should have supported INR, the rupee has continued to weaken. That divergence suggests that market demand and supply for dollars which is driven by capital outflows, import requirements and trade-finance flows is playing a more critical role than just interest rate or inflation differentials.

In other words: this depreciation isn’t just theoretical macro-economics. It’s a real, tangible squeeze on the rupee, fuelled by demand for dollars and shrinking supply (less foreign capital coming in, exporters holding off on conversions).

What Does It Means for You?

• Your costs just increased: If you’re paying for imported goods like electronics, fuel, education abroad, etc., expect higher rupee-denominated bills.
• Imports = inflation risk: A weaker rupee could feed into higher prices for fuel, food (through higher crude costs), electronics therby ultimately contributing to inflation.
• Exporters & remittances might get a boost: For companies selling abroad or Indians investing in US Stocks, earning in dollars and remitting to India, the weaker rupee improves their rupee value, although input costs for import-heavy businesses may also rise.
• What to track in coming weeks:
  
  • Any sign of improved foreign inflows (e.g. FDI, FPI)
  • Movement in global crude oil prices and import demand
  • Progress in trade negotiations with the US or other major partners
  • Policy moves or interventions by the RBI to see how aggressively it defends volatility or allows market-determined adjustments

The Bigger Picture on USDINR

The rupee slipping past ₹90 is more than just a number, it signals a shift in how India participates in global finance. For a rapidly growing economy dependent on imports (oil, metals, electronics) and foreign capital inflows, sustained currency weakness could reshape price dynamics, investment flows, and household costs.

For India, this moment could be a catalyst: one that forces policymakers, businesses, and citizens alike to rethink financial strategies by hedging currency risk, reconsider import dependencies, and build resilience in a more volatile global economy.

As the rupee wobbles, what began as a number in red could reshape finances, investments and everyday costs for millions of Indians.
