One of the biggest concerns is inflation. Higher crude oil prices and global financial uncertainty could put additional pressure on India's inflation outlook.

At the same time, the Indian rupee has remained under pressure. The rupee opened around ₹96.22 against the US dollar on October 5, while Brent crude was trading above $100 a barrel.

The RBI also appears to be watching global interest-rate movements closely. Higher rates in other major economies can make emerging-market assets less attractive and increase pressure on currencies such as the rupee.

What could a rate hike mean for ordinary Indians?

A higher repo rate can eventually translate into higher borrowing costs.

Home loans and other floating-rate loans: EMIs could rise if banks increase lending rates.

Fixed deposits: Savers could benefit if banks respond by offering higher deposit rates.

Businesses: Higher borrowing costs could make expansion and investment more expensive.

So, while a rate hike may help control inflation and support the currency, it can also make borrowing more expensive.

What about the stock market?

Indian equities have already experienced a difficult period. The Nifty 50 and Sensex were coming off an extended losing streak before Monday's recovery, with foreign selling, elevated oil prices and higher global bond yields weighing on sentiment.

Higher interest rates can create short-term pressure on interest-rate-sensitive sectors such as banks, real estate and automobiles. However, the impact will depend heavily on how aggressive the RBI signals its future policy to be.

The bigger picture

The RBI is facing a difficult balancing act: support economic growth while preventing inflation and currency pressures from becoming more persistent.

Interestingly, global markets are also watching the US Federal Reserve. Softer-than-expected US jobs data has reduced expectations of an October Fed hike, helping gold and global equities.

For Indian investors, this makes the coming days particularly important. The RBI's decision, its inflation outlook and comments on future policy could influence stocks, bonds, the rupee and loan rates.

What should investors watch?

Investors should focus on three things:

• RBI's repo-rate decision

• Inflation and growth forecasts

• The RBI's guidance on future rate hikes

Rather than reacting to a single rate decision, investors should look at the broader direction of monetary policy.

Bottom line: The October RBI policy could become an important turning point for India's financial markets. A 25-basis-point hike is increasingly expected, but the RBI's guidance on what comes next may matter even more than the hike itself.
