BIS Study Finds National Regulation Reaches Crypto Markets

The Bank for International Settlements published research on September 23, 2018, finding that cryptocurrency markets were substantially affected by national regulatory actions despite their borderless infrastructure. The study challenged a central claim of the period: that decentralized networks placed digital assets largely beyond the practical reach of individual governments.

The paper, written by BIS economists Raphael Auer and Stijn Claessens, examined cryptocurrency prices, transaction activity and user indicators around regulatory announcements. Its conclusion was not that authorities could control an underlying protocol. It was that cryptocurrency markets still depended on regulated institutions and jurisdiction-specific gateways—including banks, exchanges, payment companies and listed investment products.

A 151-event test

Auer and Claessens assembled 151 regulatory news events reported by Reuters from the beginning of 2015 through June 30, 2018. The events covered statements or actions by regulators, central banks, international organizations and standard-setting bodies. The authors classified them by subject and by whether their expected effect on cryptocurrency use was favorable or unfavorable.

The study then measured bitcoin’s response over several windows. Favorable events coincided, on average, with a 0.33% return during the 120 minutes surrounding an event and a 1.52% return over the corresponding 24-hour window. Unfavorable events were associated with returns that were 0.32% lower over 120 minutes and 3.12% lower over 24 hours.

Those figures were averages across the selected events, not a prediction for any particular announcement. The authors also observed that prices sometimes began moving before the recorded news time, indicating gradual disclosure or information arriving through other channels.

The market backdrop on September 23 remained mixed rather than uniformly responsive to the BIS publication itself. CoinMarketCap’s historical snapshot listed bitcoin at $6,710.63 with a 0.01% 24-hour change. That figure is an aggregator snapshot—not an official close in a continuously traded market—and the displayed historical table does not establish an exact publication-time reaction or causation.

Legal status carried the greatest weight

The BIS analysis found the strongest market effects around news concerning cryptocurrencies’ legal status. Announcements involving outright prohibitions, non-recognition as currency or possible treatment under securities law were associated with negative returns. News pointing toward a purpose-built legal framework outside conventional securities treatment coincided with positive returns.

Rules governing access to established financial infrastructure also mattered. The researchers identified 32 events concerning anti-money-laundering requirements or regulation of cryptocurrency intermediaries. More restrictive news in this category was associated with a median negative effect of roughly four percentage points over a 10-day window, although the distribution was wide.

Another 42 events concerned interoperability with regulated markets, including banking access, taxation, initial coin offering decisions and applications for exchange-traded funds or derivatives. The study associated this category with an average decline of about 6.4 percentage points. General government warnings, by contrast, did not produce a statistically significant valuation effect in the reported regression.

What the evidence did not prove

The September 23 publication was an empirical study, not a regulation, enforcement action or binding BIS policy. Its authors expressly stated that their views did not necessarily represent the BIS or its member central banks.

Its measurements also require caution. Event selection depended on Reuters coverage and its interpretation of importance. Price changes were winsorized at the fifth and 95th percentiles to reduce the influence of possible data outliers. Multiple announcements could occur on one day, and the study’s associations could not eliminate every overlapping market influence. Address counts were only an imperfect proxy for users because one person could control multiple addresses.

Even with those limits, the institutional implication on September 23 was significant. Decentralized settlement did not remove dependence on centralized access points. Regulators could affect valuations and participation by changing an asset’s legal classification, restricting financial-system connections or imposing obligations on intermediaries. For cryptocurrency businesses and institutional market participants, regulatory architecture was therefore part of market structure rather than an external concern.
