Q3 2018 Hedge Fund Industry Data

PublishedNovember 15, 2018
SourceOFR Hedge Fund Monitor

The third quarter of 2018 represented the absolute peak of the cycle for hedge fund leverage. Qualifying Hedge Fund NAV grew slightly to $3.380 trillion. Markets appeared deceivingly robust through late September; however, under the surface, aggressively tightening monetary policy and peaking corporate earnings created an incredibly fragile setup for the deeply leveraged industry.

Key findings this quarter:

  1. 1Qualifying Hedge Fund NAV reached $3.380 trillion before the Q4 market collapse.
  2. 2Gross Notional Exposure peaked aggressively at $21.1 trillion.
  3. 3Jerome Powell’s hawkish remarks on rate policy sparked a surge in Treasury yields.
  4. 4The industry entered Q4 carrying historic leverage into a rapidly tightening financial environment.

Macro Environment

In September, the Federal Reserve implemented its third rate hike of the year, and importantly, Chairman Jerome Powell indicated that rates were still a "long way from neutral." This unexpectedly hawkish tone sent U.S. 10-year Treasury yields soaring to multi-year highs (above 3.2%). Despite this, U.S. equities powered to record highs on the back of monumental trillion-dollar valuations in the tech sector.

Regulatory Context

Regulatory commentators warned extensively about "duration risk" and the massive buildup in corporate debt. The OFR noted that hedge funds had pushed Gross Notional Exposure to a record $21.1 trillion. The combination of high leverage, rising interest rates, and widening credit spreads in the leveraged loan market created acute systemic vulnerabilities.

Future Outlook

By the end of September, the complacency was palpable but brittle. The severe divergence between booming U.S. equities and plummeting emerging markets and commodities suggested the global growth narrative was cracking. Highly leveraged funds were exceptionally vulnerable to any sudden repricing of risk as Q4 approached.
