Sterling Tracks Interest Rate Expectations

Summary

The BOE's forward guidance is confusing investors.

Officials have, though, succeeded in stopping sterling's rally.

The confusion has also injected some volatility into sterling, which officials also may find desirable.

Forward guidance is the practice by which central banks try to shape investor expectations for the trajectory of monetary policy. Central banks have come to increasingly rely on it. BOE Governor Carney appeared to have effectively used it when he was heading up the Bank of Canada. The kind of forward he had adopted there was date specific. He gave the market some indication when the excess capacity in the economy would be absorbed. This, in turn, helped generate interest rate expectations.

Subsequently, Carney's successor was forced to push further out the time frame, and abandoned all together the temporal signal of a rate hike. Still, the greater irony of Carney's tenure at the BOE is that the grounds of his selection--ostensibly more activist than his predecessor King and more inclined to support economy while the government stuck to its fiscal austerity rhetoric--proved unnecessary. From almost Carney's first day at the BOE, the UK economy has shown unexpected vigor.

The forward guidance, for which Carney was regarded as the maestro, has proven to be confusing and contradictory. The "temporal inconsistencies," a euphemism for self-contradictory guidance, does not appear to be a cause of consternation for policy makers. It has helped stop the sterling rally, which itself was tantamount to some tightening of monetary conditions. It also has helped inject more volatility into the sterling. The 3-month implied volatility had fallen to record lows below 5% in early June, and has now held above its 100-day moving average for the first time in six months.

We have been highlighting the sensitivity of the sterling to shifting interest rate expectations since May. In this Great Graphic, created on Bloomberg, we chart the dollar against sterling, so as the dollar rises against the sterling (sterling falls against the dollar), the white line rises. The yellow line is the March 2015 short-sterling futures. It is like the eurodollar futures contract. As the yellow line rises, the implied 3-month rate next March falls.

We think there is a limit to how much further rate expectations are likely to shift in the UK. We do not think a rate cut can be reasonably discounted. In addition, as the short-sterling futures contract settles with a 3-month time deposit, even if one does not expect a hike in Q1 15, as we have consistently maintained was the most likely time frame, investors would want to be protected against a hike in Q2 15.

At the same time, the large gross long speculative sterling position in the futures market has not been unwound completely. As of August 12, the gross long position of 65.3k contracts was the largest among the currency futures. It has been culled by a third since early July. This has coincided with about a 5.5 cent pullback in the sterling against the dollar. Speculators were still carrying net long sterling position, though have been net short euros, Swiss francs and yen for some time. We should expect the gross long sterling position was cut further in the reporting period that ends today and that the bears grew the gross shorts. It might have been sufficient to shift the net position to the short side for the first time since last November.
