The news briefing, announced earlier in the day, was an unprecedented departure for the traditionally cautious central bank. Since taking the helm of the RBI in September, Rajan has pledged to be more communicative and has so far been warmly welcomed by investors.
Still, Rajan's remarks had a mixed impact on markets, sending benchmark 10-year bond prices rallying, although the rupee failed to gain much despite ending the day well above a two-month low hit earlier. Stock markets were already closed.
"It's important that the RBI clarifies interpretation of economic events and the likely direction of economic policies at times of uncertainty so that the market worries about the right things and does not get into a tizzy about the wrong ones. That is my quote today," Rajan told reporters.
"There is no fundamental reason for volatility in value of the rupee," he also said. "At some time, it makes sense to take a deep breath and examine the fundamentals. I hope you all will do that."
Rajan addressed reporters after stronger-than-expected US jobs data last week had sparked concerns about an early end to the Federal Reserve's stimulus, hitting the rupee and sending Indian bonds and shares tumbling, although markets remain well above the levels of the summer lows.
Some investors had started to fear a repeat of the summer, when the rupee slumped to a record low of 68.85 to the dollar, punished by worries about the country's vulnerability should foreign investors sell because of Fed tapering.
Analysts also cited some comfort from the governor's remarks on inflation given the RBI has raised interest rates by a half percentage point since September in two back-to-back actions as it fights off rising consumer prices.
Worries about yet another rate hike had gripped investors after India reported late on Tuesday consumer price inflation accelerated more than expected to 10.09 percent in October from 9.84 percent in September.
At his briefing, Rajan called food inflation "worryingly high", but said he was comforted by a downward trend in the core consumer price index.
"The RBI has attempted to calm the market by verbal intervention. On the policy front, it seems clear that the governor is in no hurry to hike the repo rate," said Upasna Bhardwaj, economist with ING Vysya Bank.
Rajan also surprised analysts by saying the RBI's estimate for the current account deficit for the fiscal year ending in March was USD 56 billion, the first time in recent memory the central bank has given such a forecast.
That puts the RBI's estimate in line with the government's after Finance Minister P Chidambaram said this month the current account gap would reach USD60 billion, well below its previous estimate of USD70 billion.
India's current account had been a key source of stress during the summer sell-off, but has become less of a concern as the trade deficit has narrowed on government action to curb gold imports and to raise funds from abroad.
Rajan also sought to reassure investors worried about the rupee's stability after the RBI has allowed oil companies to source dollars directly in markets instead of a special window provided by the central bank.
That window was opened as an emergency measure by the RBI in late August and was cited as a key reason behind the recovery in the rupee, which is still up 8.8 percent since its record low in late August.
Rajan said the RBI had flexibility in managing the return of oil companies to markets, and would go slow if needed.
The rupee strengthened to 63.31 from its 63.71/72 close on Tuesday, while benchmark 10-year bond yields slumped 13 basis points to 8.92 percent, marking the biggest fall in five weeks.
