The Reserve Bank of India (RBI) recorded its highest-ever monthly net dollar purchases in August 2026, buying $43.26 billion more in US dollars than it sold in the foreign-exchange market. The figure, reported in the RBI’s monthly bulletin, more than doubled July’s net purchases of $18.65 billion and marked a sharp change in the central bank’s currency-market activity.
The surge coincided with the return of dollars mobilized through the RBI’s concessional foreign-exchange swap facility, which covered Foreign Currency Non-Resident (Bank) deposits, external commercial borrowings and overseas foreign-currency borrowings. The RBI’s figures also showed a record net short dollar position in the forward market. Together, these developments offer insight into the central bank’s management of foreign-exchange liquidity, although the figures alone do not establish a particular target for the rupee’s exchange rate.

What Happened to RBI’s Dollar Purchases in August?
According to the RBI bulletin data reported by Business Standard on October 23, the central bank purchased $74.47 billion in the spot market during August and sold $31.21 billion.
The difference between those two amounts produced net purchases of $43.26 billion.
| RBI spot-market activity | July 2026 | August 2026 |
|---|---|---|
| Net dollar purchases | $18.65 billion | $43.26 billion |
| Gross dollar purchases | — | $74.47 billion |
| Gross dollar sales | — | $31.21 billion |
| Net change in purchases | — | More than doubled |

The scale of the August activity stands out against the preceding months. The RBI had been a net seller of dollars in 10 of the 17 months through August. It sold dollars consistently between August and December 2025, paused net sales in January and February 2026, and resumed selling in March.
The direction changed during the new financial year. Following net sales in April and May, the RBI became a net buyer in June and increased its purchases in July and August.
Why Did the RBI Buy So Many Dollars?
A major factor was the flow of foreign currency associated with the RBI’s concessional swap facility.
Launched in June 2026, the facility allowed eligible banks to mobilize foreign currency through FCNR(B) deposits, external commercial borrowings and overseas foreign-currency borrowings, with the associated dollars routed through a special swap arrangement.
The central bank had advanced the facility’s closure date to August 31 from September 30 after banks had mobilized $52.3 billion by August 14, according to the reporting on the bulletin.
The return of these dollars through the swap window coincided with the sharp increase in August’s net purchases. This helps explain why the record figure should not be interpreted simply as evidence that the RBI was buying dollars for one specific currency-market objective.
The facility was designed to attract foreign-currency funding and support India’s external financing position. Such arrangements can affect the timing and volume of the RBI’s reported foreign-exchange transactions.
What Does This Mean for the Indian Rupee?
A central bank’s dollar purchases can influence currency-market conditions, but the direction of the rupee depends on multiple factors.
When the RBI buys dollars in the spot market, it generally supplies rupees in exchange for foreign currency. Other things being equal, this can add rupee liquidity and create pressure for the rupee to appreciate less than it otherwise might. However, the actual effect depends on how the central bank manages the resulting liquidity and on wider market conditions.
The RBI also sells dollars when it wants to meet market demand or limit excessive currency volatility. Its operations therefore need to be viewed over time rather than judged from a single month’s net purchases.
Other factors influencing the rupee include:
- Global demand for the US dollar.
- Crude oil prices and India’s energy-import bill.
- Foreign portfolio investment flows.
- India’s trade balance and demand for imports.
- Interest-rate differences between India and other economies.
- Expectations about inflation, growth and future monetary policy.
The August data confirms unusually large net dollar buying, but it does not by itself establish whether the rupee will strengthen or weaken in subsequent months.
RBI’s Net Short Dollar Position Hits a Record
The bulletin also showed a substantial increase in the RBI’s outstanding net short dollar position in the forward market.
| Forward-market measure | July 2026 | August 2026 |
|---|---|---|
| Outstanding net short dollar position | $136.77 billion | $200.06 billion |
| Short positions maturing within one year | $47.66 billion | $55.15 billion |
| Short positions maturing after one year | $91.54 billion | $176.57 billion |
| Outstanding long dollar positions | $2.43 billion | $31.66 billion |
Source: Moneycontrol. Figures are rounded.
A forward contract is an agreement to exchange currencies at a future date. A net short dollar position means that, after accounting for offsetting positions, the RBI has an outstanding net obligation to sell dollars under its forward-market contracts.
The increase in this position is separate from the $43.26 billion in net spot-market purchases. They are different measures of the central bank’s foreign-exchange activity and should not be added together as though they were identical transactions.
The RBI’s outstanding long dollar positions also increased to $31.66 billion in August from $2.43 billion in July. The reported figures indicate that all these long positions matured within one month. After adjusting for them, the RBI’s net short position in contracts maturing within one year fell to approximately $23.5 billion in August from $45.2 billion in July.
The maturity profile matters because it provides a more detailed picture of when the central bank’s forward commitments are due to settle.
FY27 Sees a Reversal in Dollar-Market Activity
The record August purchases also changed the cumulative picture for the current financial year.
By the end of August, the RBI’s cumulative net dollar purchases in FY27 had reached $47.43 billion, compared with $4.17 billion at the end of July. This almost offset the $53.13 billion in net dollar sales recorded during the whole of FY26.
The reversal illustrates how significantly the central bank’s market activity changed over a short period.
However, net dollar purchases are not the same as the change in India’s official foreign-exchange reserves. Reserve levels are also influenced by valuation changes in currencies and gold, investment returns and other transactions. A record month of net purchases should therefore not be treated as a direct measure of reserve accumulation.
What Is the Rupee’s Real Effective Exchange Rate?
The RBI bulletin reported that the rupee’s real effective exchange rate (REER) rose to 89.35 in September from 88.72 in August.
REER is an index that measures a currency’s value against a weighted basket of trading-partner currencies, adjusted for differences in inflation. It provides a broader measure of currency competitiveness than the rupee’s exchange rate against the US dollar alone.
A rise in the index indicates real appreciation relative to the index’s base period and methodology. Depending on the circumstances, real appreciation can make a country’s exports relatively more expensive to foreign buyers and imported goods relatively cheaper for domestic buyers.
However, REER is not a direct forecast of the rupee’s next move against the dollar. It is one indicator among several that economists and policymakers use to assess external competitiveness.
The Bigger Picture
The RBI’s record net dollar purchases reflect a combination of foreign-exchange market activity and dollar flows linked to its special swap facility. The sharp change from net selling in parts of FY26 to substantial net buying in FY27 demonstrates why central-bank currency operations must be interpreted alongside the policies and funding arrangements behind them.
For businesses and investors, the more important question is how these transactions interact with the rupee, external reserves, liquidity and forward-market commitments over time. August’s numbers provide a significant data point, but they do not independently establish the RBI’s future policy direction or guarantee a particular currency outcome.
FAQs
1. How much did the RBI buy in net dollars in August 2026?
The RBI recorded net dollar purchases of $43.26 billion in August 2026, compared with $18.65 billion in July. It purchased $74.47 billion and sold $31.21 billion in the spot market during August.
2. Why did RBI dollar purchases increase sharply?
The increase coincided with dollars mobilized through the RBI’s concessional swap facility for FCNR(B) deposits, external commercial borrowings and overseas foreign-currency borrowings returning through the swap window.
3. Does buying dollars automatically strengthen the rupee?
No. Dollar purchases generally involve supplying rupees in exchange for foreign currency, which can influence market conditions. The rupee’s actual movement also depends on global dollar demand, oil prices, investment flows, trade and monetary conditions.
4. What does the RBI’s $200.06 billion net short dollar position mean?
It represents the RBI’s outstanding net position in forward-market dollar contracts at the end of August. It is distinct from the central bank’s spot-market purchases and is affected by the maturity and offsetting structure of its contracts.
5. Will the RBI continue buying dollars in the coming months?
The August data alone cannot determine future operations. The RBI’s actions will depend on market conditions, foreign-currency flows, liquidity requirements and its approach to managing exchange-rate volatility.
Looking Ahead
Future RBI bulletins will show whether the August surge was mainly a temporary consequence of swap-related flows or part of a longer-lasting shift in foreign-exchange operations. Changes in spot transactions, forward commitments and official reserves will be important indicators to watch together.
For the rupee, global dollar strength, crude oil prices, foreign investment and India’s external financing conditions will remain important influences. The record purchase figure is significant, but its implications will become clearer only as subsequent data reveal how the RBI’s currency operations and broader market conditions evolve.
