The Bond Bull Market

The bond bull market is the period of falling bond yields (and rising bond prices) that has extended over the decades since 1981. Conditions have changed dramatically through this bull market. At the outset inflation and interest rates were in double digits. Paul Volcker, the Chair of the Federal Reserve had been appointed with a mandate to rid the US (and world) economy of inflation that had contributed to the wild economic swings, high unemployment and political discontent of the 1970's. Unlike central bankers of today, future policy choices were not telegraphed to the market in advance. Surprising markets was intentional, so much so that Volcker even announced a rate increase on Saturday 6 October 1979.

It was not just policy and the desire to squeeze inflation pressures that was different, Baby-Boomers - the Post-WWII generation born between 1946 and 1964 were aged 18-36. This important demographic group had entered adulthood, and was heading towards the age of peak consumption. With easy access to credit being relatively new and governments incentivsed not to borrow by high interest rates, levels of personal, corporate and government debt were significantly lower than today - US and UK government debt stood at 31 and 45% of GDP. Today these figures are 127 and 105% respectively.

In addition, few at the start of the bond bull market anticipated the extent of political change that the world would experience. At that time, The Cold War and the division of the world between Communism and Capitalism reduced the scope for global networks and trade. The collapse of Communist economies, together with improved trade links and technologies, allowed globalisation to contribute to expanding consumer choice. This trend further reduced price pressures, creating what was increasingly known as 'The Great Moderation' - a prolonged period of (relative) economic stability in the wealthiest nations.

The Credit Crunch brought the idea of the Great Moderation to an end. The faltering recovery and rolling crises that have characterised the period since 2008 flipped policy making on its head. With inflation 'too low' and unemployment stubbornly high, central banks now actively promote the belief in their ability to stoke price pressures. Policy decisions have gone full cycle from intentional surprise and opacity to clear, long-term guidance about likely changes. Where the bond market was a means to manage the economy, leading the political adviser to Bill Clinton, James Carville to say that if he was reincarnated, "I want to come back as the bond market. You can intimidate everybody". Now no policymaker wants to wake the sleeping beast!

As the left hand chart below shows. There have been many occasions throughout the bond bull market where the downtrend in yields has been challenged. Each time yields have threatened to break this descent, another 'unexpected' crisis has emerged and served to reinstate the downtrend. With policymakers redoubling their efforts to push price levels higher, globalisation increasingly under pressure as nations question the benefits of market led economics and debt levels much higher than they have been in the past, will it be different this time?

Bitcoin 'death cross'

In technical analysis, a 'death cross' occurs when the 50-day moving average of a price drops below the 200-day moving average. In contrast to the more positive 'golden cross', this is taken as a signal of a more significant sell-off in the relevant security price. At the start of this week, the price of Bitcoin completed a 'death cross' as the sharp decline from the late April price high near $64,000 dragged the average price of the last 50-days below the 200-day average. Since 2014, Bitcoin has experienced two significant death cross events, after the strong price advances in 2013 and 2017. The charts below plot these periods, together with the smaller advance and set back in 2019.

In each case, the Bitcoin price had declined substantially from its high before the death cross occurred. The charts also show that while the price action was more extended after the death crosses occur, further significant price declines occurred before the ultimate price low was reached. The table below sets out this information in more detail. The typical loss following the death cross forming to the final low has been about 50%. The decline after the death cross has extended for as long as 8 or 9 months. The table also shows that on each occasion the death cross has occurred, there has also been a short-term rally during which the Bitcoin price has rallied back to the 200-day moving average.

2013 - The Taper Tantrum

For bond investors the months of May and June of 2013 marked a significant turning point in the post-Credit Crunch era. The extraordinary downturn in 2008 pushed the Federal Reserve into launching equally extraordinary policy responses. As official interest rates had effectively been cut as far as they could be, central banks considered alternative approaches to underpin the financial system and economy. Most notable amongst these new policies was 'Quantitative Easing' (QE). Under QE the central bank buys long-term bonds with newly created bank reserves (money). The idea being that as financial institutions sell their bonds to the central bank, they then will use the money received to increase lending to the real economy. In turn, this is supposed to boost activity.

With the sluggish recovery from the Credit Crunch, and repeated use of QE by central banks, investors had become used to the support from monetary policy. Through the summer of 2013, official statements continued to indicate that the Federal Reserve would change little and "maintain downward pressure on longer-term interest rates". Yet in testimony to Congress on 22 May by Chairman Ben Bernanke hinted at a change, saying "If we see continued improvement [in the economy] and we have confidence that that’s going to be sustained then we could in the next few meetings … take a step down in our pace of purchases [of bonds]". Nothing had changed and everything had changed. Bond markets reacted swiftly to the new possibility that QE could be unwound in the near future. The gold price, which had dipped sharply a month earlier, fell even further. The chart below shows how this statement effectively ended the declining trend in real yields that had been in place since the Credit Crunch. 

The increase in yields pushed down bond prices. Perhaps the biggest reason the 'Taper Tantrum' has entered market folklore is because equity market values dropped too. This synchronous fall in bond and equity prices caused Risk Parity funds to 'blow up'. Risk Parity funds rely on bond and equity prices moving in opposite directions to provide the stability in their returns. This approach had benefited massively from the fall in bond yields, both heading into and since the Credit Crunch. Because the strategy applies leverage to bond positions, the impact of the fall in bond prices was even more dramatic without a positive offset from rising equity prices.

Partly because the market turmoil this pronouncement on 22 May created, Dr Bernanke had to wait until December 2013 before officially announcing the tapering of QE bond purchases. This was just one month before his retirement as Chair of the Federal Reserve. While the reduction in QE bond purchases marked the start of policy tightening in America, the Federal Reserve interest rate itself did not rise until December 2015.

1980 - Silver cornered?

Through 1979 into early 1980 the price of silver soared. The price rise was so large that Tiffany's placed an advert in the New York Times calling the price increase 'Unconscionable'. For most, enormous purchases of silver by the billionaires Bunker and Herbert Hunt caused the price increase. History records this as an audacious attempt to corner the market (i.e. force an artificial shortage by buying a large share of supply) .

Whatever the intention, the silver buying by the Hunt Brothers - which had begun in 1973 with the purchase of 35 million ounces of silver - accelerated in the autumn of 1979. (In 1973 individuals in the US were still barred from owning gold by the 1933 ban on the yellow metal - the Hunt brothers claimed they merely wanted to protect their wealth from soaring inflation). By the start of 1980 they each owned 21 million ounces of physical silver, most of which had been transported to vaults in Switzerland. In addition, they also owned more than 60 million ounces of 'poor mans gold' via futures contracts.

The market became so tight that from a price of $6 in early 1979, silver hit $50.42 in January 1980. Companies from jewelry makers to industrialists and photographic film makers were badly affected by the price rise. Ultimately, the Hunt Brothers scheme unwound as dramatically as the price had risen, as exchanges allowed contracts to be settled with cash, rather than the physical deliver of silver that had been the norm, leaving the pair nursing heavy losses.

While the Hunt brothers have been vilified, many commodity prices - including gold and oil - rose sharply to significant highs around the same time. Though bond yields continued to rise for the next 18+ months as the Paul Volcker led Federal Reserve, squeezed inflation out of the US economy, the increase in consumer prices also reached its high within months of the silver market high. Was the market cornered, or was silver merely acting as a very sensitive indicator of inflation?

2017 - Bitcoin reaches $20,000

This week has brought a stark reminder of the extraordinary volatility in cryptocurrencies. With the announcement of a ban on financial companies in China from offering services using crypto, followed at the end of the week with a further crackdown on mining and trading, the price of all these digital assets has plunged.

For a time on Thursday, Bitcoin had lost more than 50% from the $64,000 peak it reached in April as FUD (Fear, Uncertainty and Doubt) replaced FOMO (Fear Of Missing Out). Time will tell if this is part of the 'normal' wild price swings that occur in this space or confirmation that cryptocurrencies are a financial excess greater than even the 17th Century Tulip mania and the 1990's NASDAQ boom.

Bitcoin has certainly experienced extraordinary volatility in the past. Both 2014 and 2018 saw the digital currency collapse by more than 80% from its high.

Yet as the charts to the left here demonstrate, the upward trend through 2017 was far from smooth. Although the price of Bitcoin started 2017 at $959, peaking a $20,089 on 17 December (the day before the Chicago Mercantile Exchange began trading Bitcoin futures), there were five declines of more than 30%. Some of those falls occurred within a single day.

The price declines this week have been extraordinary, even for the normal volatility of cryptocurrencies. 2017 shows that wild price swings - down as well as up - have long been part of the cryptocurrency experience so far.

Year 2000 - NASDAQ peaks

March 2000 marked a significant turning point for financial markets. 10 March saw the tech heavy NASDAQ index reach an intra-day high of 5,132. Five years earlier the NASDAQ index value was less than 1,000. Returns had compounded 45% a year. Yet, NASDAQ would only return to its 2000 peak once again in April 2015.

Born in the recovery from the late 80s Savings and Loans crisis in the US, the 1990s Tech Boom continued through the a series of crises: the collapse of the Japanese economy, the ERM crisis, the Mexican Tequilla and Asian Currency crises and the failure of LTCM. Every company became desperate to have its '' strategy.

In March 2000, few realised the extent of the change. Despite the existence of many of the markers of financial excess that often occur at market peaks, those warning of the risks had done so for years. They didn't understand, the new tech giants needed to 'Get big fast' - offering products for free built brand and reputation that would pay back later. Blank cheque companies could pounce on new opportunities fast, it didn't matter they had no business plan.

There are many theories about why the market peaked in March 2000, was it the announcement that Japan had once again entered recession on 13 March, or that Yahoo and eBay ended merger talks 2 days later, or that the Federal Reserve made a 'policy mistake'? The Fed raised interest rates on 21 March and 'inverted the yield curve'. The series of rate rises since early 1999 finally lifted the official central bank rate above the 10-year US Treasury yield - usually a signal of approaching market turbulence and often a warning of recession.

Whatever the cause of the turn, the changes were profound. Stocks and sectors that had struggled through the 1990s boomed. Where the 'old economy' and companies that paid dividends to shareholders had been unloved, the capital discipline this imposed contributed to surging returns after the Millennium.

2010 Higher rates ahead?

US Treasury Secretary Janet Yellen rattled investors nerves this week suggesting that higher interest rates may be needed to prevent the US economy from overheating, because of the level of fiscal stimulus planned by the Biden administration. Mrs Yellen quickly back-tracked on her comments the next day, aligning herself with the Federal Reserve view that there is unlikely to be an inflationary problem.

Uncertainty over how long interest rates will remain low after a recession has always challenged investors. The chart above looks at how bond investors anticipated a return to 'normality' after the Credit Crunch. The graphic splits the 10-year bond yield into two parts; the 5-year yield and the 5-year, 5-year forward yield (i.e. the average yields in years 1-5 and 6-10 of the 10-year bond).

Markets did not expect interest rates to remain low, as they have done (remember, when Quantitative Easing ,QE, was launched in 2009 it was supposed to be temporary too).

Though investors were willing to price in lower rates than had been typical, in early 2010 the 5-year yield was still above 2%. With short-term interest rates remained close to zero, this implied a swift tightening of policy. This belief in a rapid 'normalisation' of policy was also reflected in the 10-year Treasury. With this yield at 3.5%, investors anticipated the average interest rate in years 6-10 of the bond (i.e. from 2016 to 2020) would be above 5%. These were pre-crisis peak levels. Reality turned out differently!

2005 - Frothy US housing market

"there can be little doubt that exceptionally low interest rates on ten-year Treasury notes, and hence on home mortgages, have been a major factor in the recent surge of homebuilding and home turnover, and especially in the steep climb in home prices. Although a "bubble" in home prices for the nation as a whole does not appear likely, there do appear to be, at a minimum, signs of froth in some local markets where home prices seem to have risen to unsustainable levels."

Federal Reserve Chairman, Alan Greenspan, 9 June 2005

"So, one of the areas is asset prices, and I would say some of the asset prices are high. You are seeing things in a capital markets that are a bit frothy. That's a fact. I won't say it has nothing to do with monetary policy"

Federal Reserve Chairman, Jay Powell, 28 April 2021

Later in 2005, Alan Greenspan also reflected on periods of high market valuation saying "what they perceive as newly abundant liquidity can readily disappear. Any onset of increased investor caution elevates risk premiums and, as a consequence, lowers asset values".

Federal Reserve Chairman, Alan Greenspan, 26 August 2005

1998 - Russian debt default and the collapse of LTCM

In financial markets, the 1990s are mostly remembered for the boom in technology stocks. Underneath this headline, the reality was anything but calm. One example of this was the failure of the hedge fund, Long Term Capital Management (LTCM) in 1998. Founded in 1994, the fund had produced stellar returns. Their approach was to spot small price differences between two similar securities, and wait for the mismatch in pricing to close. Using derivatives and borrowing to amplify gains, returns rolled in.

This strategy was also to prove the undoing of LTCM. As others imitated the approach, opportunities reduced. Then, in the summer of 1998, Russia defaulted on its debts. This was a surprise to those who believed a country would never default when it can print its own money. LTCM failed as its leverage positions rapidly lost money.

The turmoil hit markets globally. Market liquidity collapsed - even the US Treasury market became difficult to trade. The impact was so great that in the middle of its extraordinary bull-run the tech heavy NASDAQ index fell 30% from its July '98 high to the 8 October low. Eventually, a rescue organised by the Federal Reserve helped restore market calm (Bear Stearns chose not to participate in the rescue, a decision that was to prove costly in 2008).

The events proved to be a major turning point for markets. Prior to this, equity markets typically fell as bond yields rose. This hang over from the 1970s reflected fears that rising inflation would lead to sharp interest rate rises. The collapse of LTCM and the rolling currency crises of the late 90s, signalled that falling asset prices were at least as big threat. For all the recent worries about inflation, the relationship between equities and bonds has yet to flip back.

1933 - America bans the ownership of gold

Arguably one of the biggest changes in the use of money came at the trough of the Great Depression in 1933. Newly elected President Franklin D. Roosevelt banned private ownership and exports of American gold.

After enforcing a Bank Holiday in March 1933 on entering office, on 5 April the new administration ordered any gold coin, bars or certificates worth more than $100 be handed in to the Federal Reserve. The price offered was $20.67 an ounce, the fixed price under the Gold Standard, which had been in place since 1879. Failure to turn in gold by 1 May was punishable with up to 10 years in prison.

Then in January 1934, the Gold Reserve Act transferred all monetary gold – including that now held at the Federal Reserve - to the US Treasury. With the price of gold also raised to $35 per ounce, the paper US dollar was effectively devalued by 59%.

The Coinbase IPO may mark another step on the road to acceptability of cryptocurrencies, history suggests that there are likely to be more regulatory bumps along the way.

The equity market downturn of 2002

While most investors have heard of the equity market bust after the Millennium. Fewer know that for most equities the biggest losses came in 2002, long after the recession in the largest economies had ended.

As the chart here shows, corporate excess from the boom years hung on market sentiment. Though the US Federal Reserve cut interest rates aggressively, this only provided temporary relief. When sentiment sagged in mid-2002, the scene was set for a sharp sell-off. 

The market recovery needed the support of new Fed Deputy Chairman's infamous "Helicopter Ben" speech in November 2002. To read the full article, follow this link

Gold bought by £100 over time

Why the interest in crypto?

“In terms of the overall fiscal sustainability of our federal government, we’re on an unsustainable path, meaning that the debt is growing faster than the economy. That doesn’t mean that the level of debt today is unsustainable. It’s not. Given the low level of interest rates, there’s no issue about the United States being able to service its debt at this time or in the foreseeable future”

Jay Powell, Chairman of the US Federal Reserve, 25 March 2021

Gold hasn’t changed over time, but money buys a lot less today than it used to. Should cryptocurrencies be viewed as digital gold?

Bitcoin v equity volatility

Bitcoin price volatility can be wild. On Monday this week, the price range between the high and low for the day was more than 10%! While this was large, it wasn't a standout in the context of the last 5 years.

The chart to the left plots the daily price range as a percentage of the day's price high. Each of these is plotted for the last 5-years. The blue dots show the same measure for global equities.

Instead of plotting the data over time, the chart ranks the daily price ranges by size, from smallest to largest. Although a 10% high-low range is off the chart for equities, this occurs about 1 in 10 days for Bitcoin.

Strong price gains and surging all-time highs have led to soaring interest in cryptocurrencies once again. The lower chart is a reminder that price volatility can occur with prices moving lower too, when prices fell in 2018, Bitcoin fell 80% from its high, and 20-30% declines are common. Not an asset for the faint hearted!
Bitcoin remains a painful thorn in the side for those who have dismissed it as a speculative bubble. Yet with no link to government or nation, nor any income generated, valuing Bitcoin is a challenge.

Some try to value Bitcoin based on stock versus flow measures, others prefer network effect valuation. Whichever is applied, the variation in market price versus 'fair value' is extremely large.

Price swings may be wild compared to fiat currencies, there is a correlation between wider US dollar strength (weakness) and Bitcoin prices. The lower chart demonstrates how this dollar sensitivity gives 'Dr Copper' a similar price pattern over recent years.

The 2016-17 period shows that Bitcoin price corrections can be severe even when the trend is up. Did the ECB's decision to act stop rising bond yields underpin the long-term bull case by showing policymakers are likely to continue to debase fiat currency?

Charts showing the year on year change in oil price and US bond yields and oil prices progressing through 2020 and 2021
For all the excitement about battery powered cars and ESG, markets are still heavily influenced by the oil price. This chart shows how US bond yields still correlate strongly with the year on year change in the oil price.

This week Jay Powell, chairman of the Federal Reserve downplayed the significance of the recent rise in bond yields. Yet the year on year change in the oil price is likely to remain a concern for markets well into May. Oil was as low as $30 in May 2020 after the lockdown price plunge. At above $60 today, that is a rise of more than 100%. Mr Powell may well get more concerned about bonds.
