RBI’s Currency Curbs Leave Markets Nursing More Than Losses

The Reserve Bank of India’s decision earlier this week to ease some of its currency market curbs, including allowing certain transactions and rollovers, signals a partial rollback of one of its most aggressive measures in defence of the rupee. Even as the rollback restores some operational flexibility, the damage from the initial intervention has largely been done and extends beyond balance sheets.

The immediate impact is clear. Banks have taken losses. Positions have been unwound. Arbitrage channels between onshore and offshore markets have been disrupted.

The more important shift is behavioural.

Markets do not forget forced losses easily.

Profits and losses are part and parcel of the market mechanism to enforce efficiency in capital allocation. When sizable positions built over time are unwound abruptly, losses will result in some corner. This is the market’s self-correcting mechanism. What distinguishes this episode is that losses did not arise from market moves alone, but from a change in the rules of the game, exit routes closed midway, and a forced unwinding of positions.

Banks are likely to respond first by recalibrating risk appetite in the immediate market of concern. Positions that rely on regulatory continuity will be sized more conservatively. What was treated as routine earlier would likely attract higher internal thresholds. More importantly, that change may not be confined to the currency market alone, as risk appetite is not compartmentalised where regulatory and monetary risks are concerned.

It can spill into government bond markets, funding markets, and even primary issuance, where banks play a critical role as absorbers of risk. A system that has just absorbed unexpected losses tends to turn defensive, not expansive.

Banks and investors will still engage, but with tighter limits, shorter horizons, and greater hesitancy, alongside a sharper focus on regulatory reversals.

Of course, in a typical capitalist environment, capital eventually chases economic opportunity. However, the leaders in charge of committing capital who sit above the operating managers may reassess risks associated with such capital commitment, in scale and product/market choices.

Policy Design
The question, then, is not whether the RBI should have acted. Few would dispute the need to respond in a period of currency pressure and global uncertainty.

The question is whether the same objective could have been achieved with lower disruption.

A more calibrated approach, including signalling, sequencing, or even limited grandfathering of existing positions, might have reduced the scale of forced losses. It would also have preserved the perception that while policy can tighten, it does not retroactively alter the economics of positions already taken.

When rules shift in ways that impose retrospective costs, risk gets priced into every trade. Over time, that shows up as wider spreads, lower liquidity, and higher costs of intermediation.

For an economy that constantly relies on the availability of adequate external capital to finance its growth needs and fund its persistent deficits, that is not a trivial concern.

Engagement Risk

There is also a subtler shift underway, one that will not show up immediately in data.

Markets engage with central banks not just through compliance, but through cooperation. They transmit policy, absorb shocks, and provide market liquidity when needed. That relationship depends on a degree of mutual confidence.

Episodes that impose asymmetric costs can strain that relationship.

The RBI has, over time, sought to deepen markets, widen participation, and introduce new products. These efforts rely on a basic assumption that participants will engage in good faith, commit capital, and build internal systems to market products to clients in addition to undertaking market making in such products, with a reasonable expectation of policy continuity.

The current episode may have had the unintended consequence (from the regulator’s perspective) of denting that behaviour. Participation may become more circumspect and tactical at best. New products, in particular, may see slower adoption, not because they lack merit, but because confidence in the operating environment has weakened.

The risk is not that markets disengage. They cannot. The risk is how they engage: more cautiously, more selectively, and with less willingness to rely on policy stability

These behavioural changes are unlikely to be visible in normal conditions. They manifest quietly and tend to surface during periods of stress. In the next episode of volatility, markets may respond more abruptly, with sharper position cuts and faster derailment of market liquidity, precisely because participants will no longer assume that such interventions are unlikely or exceptional.

That has implications for future policy initiatives. Whether it is market development, new instruments, or liberalisation steps, the success of these efforts depends on participation that is voluntary and conviction-driven, not merely opportunistic.

Rebuilding that confidence will take time.

Regulatory Signal
RBI has, over recent years, steadily moved away from prescriptive policy making to principle-based policy making. This shift placed greater onus on banks to interpret and operate within the spirit of regulation.

This episode, however, seems to have undone this shift somewhat.

Where banks uniformly believe that they have operated in a manner which is entirely consistent surely with the letter of the regulations, is it appropriate for RBI to then infer that they have not kept up with the spirit of the regulations without establishing this concretely based on evidence? Has RBI spelt out its intended ‘principle’ of the regulations which discourages Banks from building arbitrage positions? And whether RBI has engaged with the Banks to convey such a difference of opinion? Banks, for their part, claim that they have fully disclosed their positions to the RBI at all times, including during audits.

The basis on which sizeable punitive charges have been enforced on banks through the regulatory changes in this episode will discourage banks from taking RBI’s assertion on shift towards principle-based policy making on face value.

The RBI’s actions may yet succeed in stabilising the currency in the near term. Indeed, the rule changes and market illiquidity have hit speculative activity even as the rupee continues to face depreciation pressure.

The larger question is whether the cost of that stability will be paid in the form of a more cautious, less responsive and indeed less trusting market in the months ahead.

This episode does not end with the rollback. It extends to how markets price risk, reassess capital sizing, understand and interpret policy environment, and respond in the next crisis. That is where the real test will lie.
