Why the US bond market matters

Felix Martin's "Real Money" column.

On 22 May, Ben Bernanke, the chairman of the board of governors of the US Federal Reserve, made what must have seemed to innocent observers an innocuous remark: he suggested that the era of nearzero interest rates in the US could not last for too much longer and that the Fed might begin to wind down its policy of quantitative easing (QE) later this year.

The reaction of the world’s financial markets was swift and dramatic. First, the interest rate on US government bonds jumped. Then the world’s currency markets went haywire. The US stock market battled on for a few more weeks before it, too, took fright and embarked on a precipitous descent.

People who are not finance professionals might be forgiven for asking what all the fuss is about. Why, after all, should these inconsequential remarks matter so much – and so what if the interest rate on US government bonds rises by a mere 1 per cent? Is any of this relevant to normal people who don’t spend their time buried in the back pages of the Financial Times? The answer, unfortunately, is yes.

The government bond market is the axis on which the financial system of every modern, capitalist economy turns. The interest rate at which the government can borrow is the most important price in the economy – the one on the basis of which the price of every other financial asset and, indirectly, all other prices and wages are set.

Companies and individuals pay interest rates on their borrowing at rates set as a markup over the government’s rate. So if the UK government can borrow for a term of ten years at 2 per cent, then a financially robust and well-established company might be able to borrow at 3.5 per cent; and a flightier, less well-capitalised, more speculative one might be able to borrow at, say, 7 per cent. You or I, meanwhile, might be able to borrow at an even higher rate than that. When the interest rate the government pays moves, so do all the others. Thus, the interest rate on government bonds affects the entire economy.

In this matter, as in so many others, the US is more important than every other country. It is not just that the interest rate on US government bonds is the reference point for the largest economy in the world. The US dollar is also the world’s de facto reserve currency – it’s the only currency that almost anyone anywhere is ready to accept and so everybody wants to keep a precautionary store of it.

As a result, US interest rates filter through to the entire international economy as well. The US dollar is the primary currency of international finance – so that when the interest rate on US government bonds goes up, it becomes more costly not only for the US treasury to borrow at home but also for any government, company or individual almost anywhere in the world to borrow from abroad. Nor is that the end of the story. The differential between the interest rates on government bonds in different countries is a key determinant of exchange rates.

All other things being equal, if the interest rate on the US government’s bonds rises when the interest rate on the British government’s bonds remains unchanged, investors will try to rebalance their investments towards US bonds and away from British ones. As they do so, they will drive down the value of the pound sterling relative to the US dollar.

Even small changes in the interest rate on US government bonds can have a big effect on the relative value of currencies in this way – especially in the emerging markets. In the few weeks since Bernanke made his remarks, the currencies of Mexico, South Africa and Brazil, for example, have all lost more than a tenth of their value against the US dollar. This is extreme volatility of exchange rates and it can be highly disruptive of international trade and finance.

In short, the interest rate on American government bonds is the single most important regulating factor in the world economy. It’s no wonder that James Carville, Bill Clinton’s electoral strategist, reflected ruefully in 1993, “I used to think if there was reincarnation, I wanted to come back as the president or the pope . . . but now I want to come back as the bond market. You can intimidate everybody.”

So is it a good or a bad thing that US interest rates are on the rise following Bernanke’s recent pronouncements? It used to be easy to answer to that question. The link between the central bank policy or base rate and government bond yields was simple. When the economy was in rude health, the central bank would hike its policy rate and the interest rate on government bonds would rise; and when the economy was running out of steam, it would cut and bond yields would fall. Higher rates meant a healthier economy.

Since 2009, however, this transparent link between the bond market and the central bank has evaporated. With central bank policy rates stuck at zero, the bond market has had to take its cue not from monetary policy itself but from officials’ speeches and journalists’ scoops. The utterances of central bank officials such as Bernanke have become major economic data in their own right. The medium has become the message.

The result has been to turn investing in government bond markets into a kind of monetary Kremlinology, in which every passing comment of central bankers is minutely parsed for clues to the true direction of policy. In June, the new Kremlinologists concluded from Bernanke’s latest oracle that the global economy was in robust enough shape to tolerate a rise in the all-important interest rate on US government bonds.

For all our sakes, we had better hope that the divinations of the new Kremlinologists turn out to be more accurate than those of the old ones.

How Theresa May laid a trap for herself on the immigration target

When Home Secretary, she insisted on keeping foreign students in the figures – causing a headache for herself today.

When Home Secretary, Theresa May insisted that foreign students should continue to be counted in the overall immigration figures. Some cabinet colleagues, including then Business Secretary Vince Cable and Chancellor George Osborne wanted to reverse this. It was economically illiterate. Current ministers, like the Foreign Secretary Boris Johnson, Chancellor Philip Hammond and Home Secretary Amber Rudd, also want foreign students exempted from the total.

David Cameron’s government aimed to cut immigration figures – including overseas students in that aim meant trying to limit one of the UK’s crucial financial resources. They are worth £25bn to the UK economy, and their fees make up 14 per cent of total university income. And the impact is not just financial – welcoming foreign students is diplomatically and culturally key to Britain’s reputation and its relationship with the rest of the world too. Even more important now Brexit is on its way.

But they stayed in the figures – a situation that, along with counterproductive visa restrictions also introduced by May’s old department, put a lot of foreign students off studying here. For example, there has been a 44 per cent decrease in the number of Indian students coming to Britain to study in the last five years.

Now May’s stubbornness on the migration figures appears to have caught up with her. The Times has revealed that the Prime Minister is ready to “soften her longstanding opposition to taking foreign students out of immigration totals”. It reports that she will offer to change the way the numbers are calculated.

Why the u-turn? No 10 says the concession is to ensure the Higher and Research Bill, key university legislation, can pass due to a Lords amendment urging the government not to count students as “long-term migrants” for “public policy purposes”.

But it will also be a factor in May’s manifesto pledge (and continuation of Cameron’s promise) to cut immigration to the “tens of thousands”. Until today, ministers had been unclear about whether this would be in the manifesto.

Now her u-turn on student figures is being seized upon by opposition parties as “massaging” the migration figures to meet her target. An accusation for which May only has herself, and her steadfast politicising of immigration, to blame.
