Nifty's eight-day red streak ends on a late CAS rescue; the rupee slides to 95.44 and Brent hits $105

The shape of the day. For most of Thursday nothing worked: Nifty opened flat at 23,447, chopped between 23,410–23,445, ground to a noon high near 23,470, then slid with the rest of the tape after 2 PM to a low near 23,380 — on course for a ninth straight red close. The Closing Auction Session changed the story: a sharp final-half-hour move recovered nearly 100 points to settle at 23,477.80, 31 points above the open and near the day high. The eight-day losing streak was over — on a technical rescue, not a sentiment shift.

• The CAS question: The rescue is exactly what regulators are now probing. SEBI is reviewing how derivative settlement prices are calculated on expiry days since the Closing Auction Session rollout; Chairman Tuhin Kanta Pandey said "CAS is here to stay" — expect methodology changes, not a rollback. Next week's Sep 15 expiry is the first big test of the reviewed regime.

• Oil / geopolitics: Brent surged to around $105 and WTI breached $100 after Iran-aligned Houthi forces seized Mocha, Yemen's strategic port city — leverage over the Bab el-Mandeb Strait, on top of the Hormuz disruption. OPEC cut its 2026 global demand-growth forecast to 380,000 bpd from 580,000 bpd, a fifth straight downward revision.

• Currency: The rupee fell 0.3% to ₹95.44 — a third straight session of losses and its steepest single-day fall since mid-July — as derivative-maturity dollar demand and corporate hedging met an oil-import bill running above $100 crude. The RBI leaned against it with dollar sales and FX swaps.

• Flows beneath the surface: The structural bid keeps buying while foreign money sells: in August, SIPs took a record ₹32,297 crore and equity funds ₹29,329 crore (+18.8% MoM), with small-cap (₹7,973 crore) and mid-cap (₹6,989 crore) funds at monthly records even as the index streaked red.

• Positioning: For the Sep 15 expiry the OI ladder shifted up: maximum Call OI sits at 24,000 then 23,500 (resistance 23,600–23,700); maximum Put OI at 23,000 then 23,400 (support 23,300–23,200) — Sensibull data via Zerodha.

• The five-session picture: Over the last five sessions FIIs sold a net ₹5,884 crore while DIIs bought a net ₹17,333 crore — the absorption pattern that carried the market through an eight-day red streak without an index collapse.

• Sep 10 print: The Sep 10 provisional FII/DII file was not published at our cutoff, so Thursday's figures are left unshown rather than estimated. The 5-day aggregates above already include the shape of the week.

• Why it matters: DII absorption funded by record SIP flows is the mechanism holding the index together — FII selling of ₹5,884 crore over five sessions moved Nifty less than 500 points. If FII selling stays this shallow while SIPs run at ₹32,000 crore a month, the put-OI shelf at 23,300–23,200 holds.

• Record SIP month: August SIPs took a record ₹32,297 crore (+1.1% MoM) and overall equity inflows jumped 18.8% to ₹29,329 crore. Small-cap funds took a record ₹7,973 crore and mid-cap funds ₹6,989 crore — retail money keeps scaling the risk curve even as the index streaked red.

• Tokenised bonds arrive: SEBI launched Demat 2.0, a pilot for tokenised corporate bonds — issued, held, traded and settled on tokenisation rails — led by CDSL and NSDL with exchanges, banks, NPCI and investors; three issuers have already issued tokenised bonds under it.

• Deployment lag, not a wall of money: The record FCNR(B) raise ($127.22 billion, RBI data) reaches loan books with a three-to-four month lag, per SBI's chairman — debt-fund and credit narratives should price deployment, not instantaneous flows.

• NFO watch: No new major fund offers were flagged in this morning's sources.

• Rupee at 95.44: Three straight sessions of losses — the steepest single-day fall since mid-July — as oil above $100, derivative-maturity dollar demand and corporate hedging bit despite RBI dollar sales and FX swaps. Every ₹1 of weakness raises the imported cost of the crude India needs.

• The oil-import bill: India imports about 90% of its crude. Bank of Baroda estimates a sustained $1 rise in crude adds roughly ₹18,000 crore to the annual import bill — Brent is now about $5 above where it traded last week.

• Xi lands tomorrow: Chinese President Xi Jinping visits India on September 12–13 for the 18th BRICS Summit in New Delhi — his first trip here in seven years, with a Modi–Xi bilateral expected amid a gradual post-2020 thaw.

• FCNR(B) record: Banks raised a record $127.22 billion through FCNR(B) deposits under the RBI swap facility — a stability cushion for the external account, with deployment lagging three to four months (SBI).

• ECB hiked: The ECB raised rates 25 bps — its second hike since the Middle East war began — taking the deposit rate to 2.50% and the main refinancing rate to 2.65%, citing energy-led inflation likely to stay above its 2% target for an extended period.

• US producer inflation hot: PPI rose 0.4% MoM in August — the sharpest in three months — with goods +1.1% and diesel +24.1%. US CPI is due today; the squeeze on global rates has not peaked.

• Oil: two chokepoints now: Brent surged to around $105 and WTI breached $100 as the Houthis seized Mocha — leverage over Bab el-Mandeb on top of the Hormuz disruption. OPEC cut its 2026 demand-growth forecast for a fifth straight revision.

• China–India thaw: Xi Jinping visits September 12–13 for the BRICS Summit in New Delhi — the first Chinese presidential visit in seven years, with a bilateral expected amid a gradual border-tension thaw.

“CAS is here to stay.”

“I think everybody will be more responsible. It will take about three to four months for the deployment of the liquidity. I don't think it will happen in the next month. And as we speak, also contributed by the FCNR(B) flows, we have excess SLR of ₹4 lakh crore.”
