Fed Rate Hike to 3.75%-4% Triggers Global Tightening Wave and Forces RBI October Decision

The US Federal Reserve resumed its rate-hike cycle on September 17, raising its benchmark rate by 25 basis points to a range of 3.75%-4.00% and signaling further tightening ahead. The move reverberated across global markets, with the US 10-year Treasury yield approaching 5%, gold extending gains for a second consecutive day as yields partially reversed, and Bloomberg Intelligence strategist Mike McGlone arguing that 5% US bond yields now give investors a compelling reason to rotate out of Bitcoin and gold into Treasuries.

The Bank of Japan compounded the global tightening picture by raising its benchmark rate to 1.25%, a 31-year high, and signaling readiness to keep lifting borrowing costs. ECB President Lagarde separately described the rise in yields as a global trend, while the French 10-year bond yield premium over German Bunds widened to 100 basis points. Eurozone benchmark yields were nonetheless on track for their first weekly decline since early August, as investors scaled back bets on further ECB hikes in light of the broader surge in global borrowing costs.

For India, the Fed's move sharpened the stakes ahead of the Reserve Bank of India's October 5-7 policy meeting. The rupee has weakened to near 96 per US dollar, Brent crude holds above $100 per barrel, and headline CPI came in at 4.82% in August with core inflation firming. Indian 10-year government bond yields have climbed to around 7.05%, a four-month high, and Indian bonds fell for a fifth consecutive week as shrinking US-India yield spreads and foreign portfolio investor debt outflows weighed on the market. Bank of Baroda forecasts the 10-year yield to range between 6.95% and 7.12%.

Economist views on the RBI's next move are split. Emkay Global's Madhavi Arora sees a 25 basis point hike in October as increasingly probable, with an overall shallow tightening cycle of 50-75 basis points. Axis Capital's Prateek Ancha projects up to 50 basis points of RBI tightening across the October and December meetings. Ventura Research's Vinit Bolinjkar anticipates a pause in October paired with hawkish forward guidance, while Choice Institutional Equities' Purvi Mundhra notes that keeping real policy rates near 1% could ultimately imply a nominal repo rate target of 6.5%. Shriram Group's Apoorva Javadekar warns that rate hikes aimed at defending the rupee risk dampening domestic growth. Analysts flag 7.25% on the 10-year yield as the critical level to watch if global and domestic pressures persist.
