BoJ Sparks Market Chaos With Huge 'Yield Curve Control' Adjustment

The Bank of Japan shocked markets tonight.

After leaving policy rates unchanged, the 'easiest' bank in the world decided to dramatically modify its so-called Yield Curve Control framework and increase the quantity of government bonds it will buy each month (while the rest of the world is doing the opposite).

The increase in range is huge (from -0.5% to +0.5% in yields). Thus, realistically this is a tightening policy move allowing long-rates to rise from 25bps (the prior YCC limit) to 50bps (the current YCC limit)...

The YCC adjustment is being reported as a mechanism to encourage better functioning in the bond market (where barely a bond changes hands nowadays). The BOJ says it made the change as:

“the functioning of bond markets has deteriorated, particularly in terms of relative relationships among interest rates of bonds with different maturities and arbitrage relationships between spot and future markets... If these market conditions persists, this could have a negative impact on financial conditions.

The BoJ also increased its bond purchases to JPY9 trillion per month for January through March.

Bear in mind that the share of Japanese government bonds held by the Bank of Japan has topped 50% on a market value basis for the first time, new data showed Monday.

As one might expect, Cash JGBs didn't budge on the news.

Interestingly, despite the 'easing' implied by the JGB buying increase, the JPY strengthened against the dollar (because with a wider/higher band for the 10Y yield, theoretically the BoJ will have to buy fewer bonds to keep it within their limit). The JPY is now at its strongest since August.

Until, of course the next depressionary collapse.

So the bottom line is that The BoJ will allow 10Y to rise to 0.50% from 0.25% but in order to make the transition as painless as possible, it will increase bond purchases to Y9 Trillion from Y7.3 Trillion per month.

This will basically remove the YCC kink in the JGB yield curve...

And sure enough, 10Y JGB yields have instantly exploded higher to their highest since 2015...

JGB Futures trading has been halted on the Osaka Exchange.

Japanese bank stocks are soaring on the increased outlook for their NIMs...

Capital Economics offers some clarifications as traders comes to terms with WTF Kuroda just did...

There was nothing in the statement that would suggest that this decision heralds a wholesale tightening of monetary policy.

For one thing, the bank’s assessment of current economic conditions as well as its outlook over coming quarters was little changed from the October meeting.

If anything, the downgrade to the bank’s view on external demand suggests that it is getting increasingly worried about the strength of the recovery.

Most importantly, the bank reiterated that it expects short-term and long-term policy rates to remain at their present or lower levels.

Daisuke Karakama, chief market economist at Mizuho Bank, warned about taking these initial kneejerk moves as indicative of anything:

“FX markets seem to want to take it as BOJ’s pivot, which I do not think so.” 

The BoJ's dramatic adjustment to its yield-curve control framework could reflect policymakers’ preference for a stronger yen, according to National Australia Bank.

“The widening of the band has been framed as a move to improve market functionality, but implicitly one could argue the bank now has a preference for a stronger yen (or at a minimum a distaste for further yen weakness),” Rodrigo Catril, the bank’s Sydney-based strategist says.

“On face value the YCC announcement reinforces the view that the BOJ willingness to wait for the right type of inflation does have limits.”

This action by The BoJ has sparked chaos in other markets with US Treasury yields spiking...

As Bloomberg's Yuki Masujima said:

The implications go far beyond Japan - with the BOJ - the last major holdout in a global monetary tightening shift (with the exception of China) — now letting the benchmark yield trade higher than before, the shock will echo across global financial markets.

Bitcoin has spiked (likely on the rise in BOJ QE - which is actually offset by the BOJ 'allowing' rates to rise, thus tighten)...

Gold jumped back above $1800...

And US equity markets are tumbling...

...and just as liquidity evaporates for the Xmas break across global markets.

The governor had repeatedly stuck to a resolutely dovish stance by stressing the need for stimulus until stronger wage growth takes place, ruling out the possibility the BOJ will take action against the yen’s slump.

He had also characterized any widening of the movement band around the yield target as equivalent to a rate hike, a description that led most economists to believe such a move was still some time away.

Or maybe that was Kuroda's cunning plan after all - offer no hint at all of this and then drop it during one of the most illiquid times of day during one of the most illiquid weeks of the year, so the effect is immediate - like ripping off a band-aid.

Presumably, the smart chaps in the BOJ believe they can allow the yield to jump and traders will happily let it rest there at 50bps. Of course that won't happen and Kuroda's successor will be forced to buy ever increasing quantities of JGBs to maintain the 50bps yield upper band.
