USD/INR extends upside on increased demand for US Dollar

• The Indian Rupee trades in negative territory in Tuesday's Asian session.
• A weak tone in the domestic markets and persistent outflows weigh on the INR. 
• Traders await the US December ISM Services PMI, which is due later on Tuesday.

The Indian Rupee (INR) remains weak on Tuesday after bouncing off a record low in the previous session. The local currency remains fragile amid broad-based US Dollar (USD) bids. Furthermore, a steep fall in domestic equity markets and an unabated outflow of foreign capital contribute to the INR's downside. 

On the other hand, the Reserve Bank of India (RBI) intervention could help contain further loss in the local currency. Investors will closely watch the development surrounding the incoming US administration under Donald Trump's tariff plan. Analysts believe that if US tariffs are broadly lower than Trump promised on the campaign trail and aimed only at critical sectors, then the outlook for global growth should improve and the USD should weaken.

The US ISM Services Purchasing Managers Index (PMI) is due later on Tuesday. On Wednesday, the minutes of the Federal Reserve's (Fed) December policy meeting will be published. All eyes will be on the US Nonfarm Payrolls (NFP) report on Friday.

Indian Rupee loses ground amid domestic and global challenges

• The HSBC final India Services PMI eased to 59.3 in December from 60.8 in a preliminary estimate. This reading came in below the consensus of 60.5. 
• "Forward-looking indicators such as new business and future activity suggested that the strong performance will likely continue in the near future," said Ines Lam, economist at HSBC.
• Trump denied the Washington Post story that his aides are considering narrowing his tariff plan so that it would only apply to specific critical imports. 
• Fed Governor Lisa Cook said on Monday that Fed policymakers could be more cautious with further rate cuts, citing labor market resilience and stickier inflation. 
• The US ISM Services PMI is expected to improve to 53.0 in December from 52.1 in November.

USD/INR's bullish bias prevails, overbought RSI conditions could limit its advance 

The Indian Rupee softens on the day. The USD/INR pair remains on a bullish trajectory as the price has broken above the ascending trend channel over the past week and holds above the key 100-day Exponential Moving Average (EMA) on the daily chart. 

Nonetheless, the 14-day Relative Strength Index (RSI) moves beyond the 70.00 mark, warranting some caution for bulls. The overbought condition suggests that further consolidation cannot be ruled out. 

The crucial upside barrier emerges at an all-time high of 85.84. Sustained trading above this level could pave the way to the 86.00 psychological mark. 

On the downside, the low of January 6 at 85.60 acts as an initial support level for USD/INR. Further south, the next contention level is located at 85.00, followed by 84.45, the 100-day EMA.
