"The irony is that a more measured pace of liquidation would have allowed the fund to profit from the bond market 'flash rally' of October 15, 2014," visiting BIS professors Lawrence Kreicher and Robert McCauley wrote in the paper. "In any case, it appears that a huge long eurodollar position could be and was liquidated in a fortnight. By contrast, [the TRF's] liquidation of its 'short volatility' position may have contributed to the 'flash rally,'" by setting off a wave of hedging amongst dealers who scrambled to absorb Pimco's short position.
The use of eurodollar futures has not been confined to the world's erstwhile biggest bond fund, with the BIS paper noting that while asset managers play a diminished role in day-to-day trading, they "generally hold the largest eurodollar positions among buy-side participants." Their "dominance in positioning establishes them as gatekeepers for the Fed's forward guidance" limiting the U.S. central bank's ability to change monetary policy if asset managers are not positioned accordingly — as seen in the 2013 taper tantrum.
Investors seeking to boost returns at a time of abundant liquidity and unconventional monetary policy have also applied leverage to corporate credit, a market which has exploded in size thanks to low interest rates and yield-hungry investors who have enabled companies to sell more of their debt. While the use of single-name CDSs that offer insurance-like payouts to a single security, company, or government, has diminished in the wake of the financial crisis, trading tied to indexes comprised of multiple entities has jumped.
With corporate default rates at historic lows and with stimulus increasing correlation between asset classes, use of so-called CDS indexes has boomed as both a trading and hedging tool, allowing investors to create an "overlay" on their portfolios to protect against a systemic rise in defaults at a time when liquidity is said to have deteriorated.
Further complicating matters is the explosion in alternative derivatives or 'derivatives of derivatives,' with investors now served an expansive menu of exotic synthetic credit products including options on total return swaps (TRS) and options on CDS indexes.
Such 'swaptions,' as they're sometimes known, give investors the right to buy or sell the index at a particular date and for a certain price, and are said to have surged in popularity in recent years. Analysts at Citigroup Inc. estimated that about $24 billion of CDS index options traded in 2005, rising to $1.4 trillion in 2014 — a more than a 5,000 percent jump in activity in just under a decade.
Strategists at Barclays Plc have expressed concerns that the rapid rise in CDS index option volume was impacting the underlying index, while a senior credit trader at one of the biggest banks told Bloomberg earlier this year that the notional volume of credit index options traded has on some days surpassed the volume of trades in the referenced index. A more recent survey by Citigroup Inc. analysts earlier this year showed 72.6 percent of investors expressed concerned over how "investors are taking more leveraged risk using derivatives."
In the equity market, a jump in the number and amount of products tied to the Chicago Board Options Exchange's Volatility Index, the VIX, are sometimes said to be impacting the index itself. While the VIX, which is based on options contracts tied to the S&P 500, remains far below its financial crisis highs, volatility of the index itself last year reached an all-time record.
