RBI 'defending' rupee, capital account convertibility, & can tax policy drive jobs

ELI5/TLDR

A viewer Q&A on Indian macro plumbing. Bidisha Bhattacharya walks through what RBI is actually doing when it “defends” the rupee (spoiler: mostly smoothing expectations, not pegging a number), why full capital account convertibility hasn’t happened and probably shouldn’t, why differential corporate tax rates only nudge corporate behaviour at the margins, and why Japan keeps breaking the Philips curve. No fireworks, but a clean tour of the toolkit.

The Full Story

What RBI is actually doing to the rupee

The viewer’s framing — that RBI is in a “defending zone” and that this signals weakness — gets gently rejected. India runs a managed float, not a peg. RBI has four tools, and it’s been rotating between them in quick succession: spot dollar sales, domestic liquidity management, FX swaps (lending dollars to banks short-term and taking them back later), and intervention in the offshore NDF market where traders bet on the rupee’s future direction without ever owning it.

The subtle point Bidisha keeps returning to is expectations. Currencies don’t move only on trade flows and fundamentals. If NDF traders start pricing in further weakness, that bet leaks back into the onshore market and amplifies the move. This is why RBI sometimes acts on offshore positions even when nothing has changed in the real economy. It’s not defending a level — it’s interrupting a feedback loop.

The corollary, which she states explicitly, is that signalling matters. The moment markets believe RBI is committed to a particular exchange rate, speculators have a free target. So the activity is deliberately varied — swaps one week, NDF restrictions the next, relaxation after that — to keep the regime opaque and the level unanchored.

Capital account convertibility — not dead, just deferred

The Narasimham Committee (1991) flagged the idea; the Tarapore Committee (late 1990s) drew the actual roadmap, conditional on four things: low stable inflation, fiscal discipline, strong banks holding adequate FX reserves, and strong financial markets.

India has steadily liberalised — FDI, FPI, LRS for outbound investment within limits. What remains tightly managed is short-term capital. Bidisha’s argument against full convertibility is the standard one but worth saying plainly: in a risk-off event (her examples: 2008 GFC, current Middle East tensions), capital flees emerging markets fast, and a fully open capital account would mean RBI watches the rupee crater without any plumbing left to slow it down. Her view: the goal hasn’t disappeared, it has evolved. A maturing economy doesn’t necessarily mean a fully open one.

Why countries can’t simply set their exchange rate

A nice fundamentals detour prompted by a viewer asking how the world “agrees” on currency values. It doesn’t. Currencies are priced by the FX market on demand and supply, driven by three things: trade flows (India imports oil → buys dollars → rupee weakens), investment flows (capital chasing safety or yield), and trust/stability (still 58–60% of global FX reserves are in dollars).

How much a country can influence its own currency depends on the regime it picks: floating (US — no intervention), fixed (Saudi pegged to the dollar — requires huge reserves to defend), or managed float (India — intervene only on disorderly moves). And — a point easy to forget — emerging economies often don’t want a strong currency. A weak rupee makes exports competitive. Bidisha cites her own August/September 2025 piece “Let the Rupee Fall” as the long-form version of this argument.

License Raj, mindset, and what actually changes it

A viewer asks how to dislodge the post-independence suspicion of business — the “capitalist profiteer black marketer” frame that hardened during License Raj and arguably still lingers in West Bengal, UP, Bihar.

Bidisha’s answer is structural, not pastoral. She walks through the layers: state-led development from 1951 to 1991, scarcity economics (high prices read as exploitation in poor countries even when they’re rational price signals), militant labour unions of the 60s and 70s that started as protection and ended as rigidity, then red tape and bureaucratic discretion stacking on top. Result: capital outflow from those states and de-industrialisation.

Her prescription: don’t try to change the mindset directly. Change the system. Simpler rules, transparent processes, visible outcomes (the IT/services boom from 2000 onwards did more for the public’s view of business than any campaign), balance labour protection with business flexibility, reduce bureaucratic discretion via single-window systems and digital compliance. Mindset follows results.

Differential corporate tax rates as policy lever

Can you steer corporations into more R&D, hiring, higher wages, and reinvestment using differential tax rates? Her short answer: somewhat, but demand is the real driver.

R&D: India had a “super deduction” until 2020 that genuinely encouraged R&D spend — and was also gamed, with companies repackaging non-research activity as R&D.
Hiring: tax credits don’t create demand. Without underlying demand for the product or service, hiring incentives don’t move the needle.
Wages: even more limited. Wage levels are set by productivity, skills, and competition for talent, not tax breaks.
Reinvestment: this is where tax policy actually has bite. Encouraging firms to retain and reinvest profits rather than distribute them does compound into growth.

Standard rates: India’s lowest manufacturing slab is 15%, Ireland 12.5%, global typical range 23–25%.

Healthcare, teaching, and firm formalisation

Two follow-up questions on the social sector. India’s doctor-to-population ratio is roughly 1:1500 against a WHO norm of 1:1000. Government schools are short of teachers, and applications to teacher-training institutes have dropped. Pay scales are too low relative to what these professions should command.

She flags the standard fiscal worry: with manufacturing now a strategic priority (because services alone can’t close the trade deficit), social sector capex is the line item most likely to get postponed. Capital expenditure always loses to revenue expenditure when budgets get squeezed.

On formalisation, her three-tier model: centre designs policy, states deliver efficiency, local bodies handle delivery. The lever for moving informal businesses into the formal system is incentives — easier credit access, eligibility for government schemes, infrastructure access — not penalties. Tier 2 and tier 3 cities are where most of the unmet demand and unutilised workforce sit.

Japan and the broken Philips curve

Final question, riffing off a recent IMF Article IV consultation report on Japan (3rd April). Wage growth is strong, unemployment near multi-decade lows, yet inflation is barely at the 2% target. Textbook Philips curve says inflation should be running hot. It isn’t.

Bidisha’s diagnosis: 30 years of stagnant prices have rewired expectations. Japanese consumers are extraordinarily price-sensitive — any meaningful increase would be a shock. So firms are absorbing input cost increases rather than passing them through. Strong productivity helps absorb the rest. Wage growth isn’t translating into inflation because the transmission mechanism has been broken by three decades of conditioning.

Her takeaway: macroeconomics can’t lean on the Philips curve as a standalone tool anymore. Expectations and productivity need to be in the model alongside the headline rates.

Key Takeaways

Four RBI rupee tools: spot dollar sales, domestic liquidity ops, FX swaps (short-term dollar provision to banks), NDF market intervention.
Why intervention varies week to week: prevents markets from inferring a defended level; signalling a target invites speculative attack.
Tarapore Committee’s four conditions for full convertibility: low stable inflation, fiscal discipline, strong banks with adequate reserves, strong financial markets.
Dollar’s reserve dominance: 58–60% of global FX reserves still denominated in USD.
Corporate tax rates: India 15% (lowest manufacturing slab), Ireland 12.5%, global range 23–25%. Super deduction for R&D removed in 2020.
Doctor ratio: India ~1:1500 vs WHO norm 1:1000.
Japan puzzle: low unemployment + strong wage growth + ~2% inflation. Firms absorb costs; productivity absorbs the rest; 30 years of low inflation has reset consumer expectations.
Three exchange rate regimes: floating (US), fixed (Saudi peg), managed float (India).

Claude’s Take

This is a reasonable Q&A format — undergraduate macro with Indian examples, delivered cleanly. Bidisha’s strongest move is the repeated insistence that RBI is managing expectations, not defending a number, and that varying the toolkit is itself a strategy. The capital account answer is the right answer (full convertibility in an EM with a structural CAD is asking for trouble), even if it’s also the conventional one.

Where it thins out: the corporate tax section is correct but generic, and the License Raj answer leans on familiar narrative beats without much new colour. The Japan piece is the most interesting, mostly because the Philips curve breakdown is the kind of thing that should change how analysts read every economy with persistently low inflation, not just Japan. Expectations have eaten more of the model than economists like to admit.

A 6 — solid, accessible, no real edge over what you’d get from reading her column directly. Useful as a refresher; not essential.
